2. What Determines Bulk SMS Rates in India?

Bulk SMS pricing in India is not a flat rate — it is a dynamic price influenced by at least seven distinct variables. Understanding these helps you compare quotes intelligently and avoid overpaying.

Factor 1: Message Type (Route Category)

TRAI classifies all commercial SMS into four route categories, each with different pricing:

• Promotional SMS — Lowest cost. Marketing campaigns, offers, discounts. Cannot reach DND numbers. Allowed only 9 AM to 9 PM.

• Transactional SMS — Medium cost. Account alerts, order updates, appointment confirmations. Can reach DND numbers. Allowed 24/7.

• Service Implicit SMS — For services the user has consented to implicitly (e.g., banking relationships). Similar cost to transactional.

• Service Explicit SMS — For services requiring explicit written consent. Slightly higher cost due to consent verification overhead.

• OTP SMS — Highest priority route. Sub-2-second delivery requirement. Highest cost due to premium carrier routing.

Factor 2: Message Volume

Bulk SMS pricing in India follows a tiered discount model — the more you send, the less you pay per SMS. Providers typically offer 4–6 volume tiers:

Monthly Volume	Typical Rate Range (Promotional)	Typical Rate Range (Transactional)
Up to 10,000 SMS	₹0.18–₹0.25/SMS	₹0.22–₹0.30/SMS
10,001–1,00,000 SMS	₹0.14–₹0.18/SMS	₹0.18–₹0.25/SMS
1,00,001–10,00,000 SMS	₹0.11–₹0.14/SMS	₹0.15–₹0.20/SMS
10,00,001–1 crore SMS	₹0.10–₹0.12/SMS	₹0.13–₹0.17/SMS
1 crore+ SMS	₹0.08–₹0.10/SMS	₹0.11–₹0.15/SMS

Factor 3: Route Quality (Tier-1 vs Grey Routes)

This is the most misunderstood pricing factor in the Indian bulk SMS market. Routes are classified into:

Tier-1 (Direct Carrier Routes): Messages are routed directly through Jio, Airtel, Vodafone Idea, or BSNL's own SMSC infrastructure. Fastest delivery, highest delivery rate (99%+), DLT-compliant, but higher cost.

Tier-2 (Aggregator Routes): Messages go through one or more intermediary aggregators before reaching the carrier. Slightly slower, delivery rate 95–98%, still DLT-compliant.

Grey Routes: Messages bypass DLT entirely, often using SIM farms or international routes misrepresented as domestic. These appear extremely cheap (₹0.05–₹0.08/SMS) but violate TRAI regulations, risk carrier blocking, generate fake delivery reports, and can result in fines. TechTo Networks never uses grey routes.

Factor 4: DLT Compliance Overhead

Since TRAI's DLT mandate in 2020, every commercial SMS must be registered and verified on the DLT blockchain before delivery. The per-SMS DLT processing fee is approximately ₹0.025 per message — a cost that every provider must pay to the telecom operators. Some providers include this in their quoted rate (transparent), while others add it as a separate line item on your invoice (hidden).

Factor 5: Sender ID Type

• Shared Sender ID (e.g., SENDER, NOTIFY): Lower cost — shared among multiple clients

• Dedicated Sender ID (e.g., TECHTO, BKAXIS): Higher cost — exclusive to your brand, typically ₹500–₹1,500/month extra

• Numeric / Short Code: Used for international SMS; premium pricing applies

Factor 6: Message Character Length

Standard SMS in India is 160 characters for English (ASCII) content. Unicode messages (Hindi, Tamil, Telugu, Kannada, etc.) are limited to 70 characters per SMS part. Messages exceeding these limits are billed as multiple SMS units:

• 161–306 characters = 2 SMS credits charged

• 307–459 characters = 3 SMS credits charged

Unicode (regional language):

• 71–140 characters = 2 SMS credits charged

• Every additional 67 characters = +1 SMS credit

Factor 7: Contract Duration and Commitment

• Pay-as-you-go (PAYG): Highest per-SMS rate, maximum flexibility, no expiry pressure

• Monthly prepaid pack: 15–25% discount vs PAYG; credits valid for 30 days

• Quarterly/annual pack: 30–40% discount; ideal for predictable volume businesses

• Enterprise annual contract: Custom pricing, SLA guarantees, dedicated support, 40–50% discount

3. Promotional SMS Rates in India 2026

Promotional bulk SMS is used for marketing campaigns — sale announcements, discount codes, product launches, event invitations, and customer re-engagement. It is the most widely used and most competitively priced category.

What Is Promotional SMS?

• Sent to opted-in customers or the general public for commercial promotion

• Cannot be delivered to DND-registered numbers

• Can only be sent between 9:00 AM and 9:00 PM (TRAI mandate)

• Sender ID is typically a 6-character alphanumeric (e.g., SHOPNW, OFFERS)

• Must use a TRAI-DLT registered promotional template

• Travel and hospitality: Booking offers, seasonal deals, cancellation notifications

4. Transactional SMS Rates in India 2026

Transactional SMS is triggered by a customer action — it is sent in response to something the user has done, not as a broadcast. It carries a higher delivery priority than promotional SMS and a correspondingly higher cost.

What Is Transactional SMS?

• Sent as a direct result of a customer-initiated action

• Can be delivered to DND-registered mobile numbers

• Can be sent 24 hours a day, 7 days a week with no time restrictions

• Higher delivery priority — carrier networks process transactional messages ahead of promotional

• Sender ID is typically a 6-character alphanumeric (e.g., BANKAX, ORDNOW)

• Must use a TRAI-DLT registered transactional template

Transactional SMS Pricing — TechTo Networks 2026

Pack Size	Total Credits	Rate per SMS	Total Cost	Validity
Starter	10,000 SMS	₹0.22/SMS	₹2,200	6 months

• Healthcare: Appointment reminders, lab report availability, prescription refill alerts, discharge summaries

• Insurance: Policy renewal reminders, claim status updates, payment confirmations

• Logistics: Dispatch confirmations, estimated delivery times, delivery attempt notifications

• Government: Application status updates, scheme notifications, benefit disbursal confirmations

5. OTP SMS Rates in India 2026

OTP (One-Time Password) SMS commands a premium rate because it demands the highest delivery reliability and the fastest delivery speed. India sends over 5.5 billion OTP messages every month — the highest volume of any single market globally — driven by UPI mandates, digital banking, and app-based verification flows.

What Is OTP SMS?

• Time-sensitive verification code (4–8 digits), valid for 30–180 seconds

• Must be delivered in under 5 seconds to meet user experience standards (sub-2-second is gold standard)

• Can reach DND numbers (transactional classification)

• Sent 24/7 with no time restrictions

• RBI mandates OTP 2FA for all UPI and card transactions above ₹5,000

• Requires TRAI-DLT registered OTP template with {#var#} placeholder

OTP SMS Pricing — TechTo Networks 2026

Pack Size	Total Credits	Rate per OTP	Total Cost	Validity
Starter	10,000 OTPs	₹0.28/SMS	₹2,800	6 months
Growth	50,000 OTPs	₹0.24/SMS	₹12,000	6 months
Business	1,00,000 OTPs	₹0.22/SMS	₹22,000	12 months
Professional	5,00,000 OTPs	₹0.20/SMS	₹1,00,000	12 months
Enterprise	10,00,000+ OTPs	₹0.18/SMS	Custom	12 months

Multi-channel fallback (Voice OTP, WhatsApp OTP) available as add-on. DLT charges included. GST @ 18% applicable.

Why OTP SMS Costs More Than Promotional SMS

Providers charge more for OTP SMS because:

1. Tier-1 exclusive routing — OTPs must use direct carrier routes, not aggregator paths, to guarantee speed

2. Priority queue position — OTP messages are processed at the front of carrier queues, ahead of all other traffic

3. Real-time delivery confirmation — Webhook-based DLR (Delivery Receipt) must fire within milliseconds of carrier acknowledgment

4. Failover infrastructure cost — Multi-channel fallback (SMS → Voice → WhatsApp) requires maintaining multiple carrier integrations simultaneously

5. SLA penalty risk — Enterprise OTP contracts often include financial SLA penalties for missed delivery windows, which providers price into their rates

6. SMS API Pricing in India 2026

Businesses that integrate bulk SMS into their applications, websites, or CRMs via API do not pay a separate "API fee" with most modern Indian providers — they pay the same per-SMS rates as dashboard users, with the API itself provided free of charge.

What TechTo Networks API Access Includes (Free)

• Full REST API access with HTTP GET and POST endpoints

• JSON and XML response formats

• Sandbox/test environment for development

• SDKs for Node.js, Python, Java, PHP, Ruby, .NET

• Webhook support for real-time delivery receipts

• API documentation with code samples in 6 languages

• Rate limit: 1,000 API requests per minute (enterprise: custom)

• IP whitelisting and API key rotation supported

• SMPP connectivity for high-volume enterprise integrations

API-Specific Pricing Note

Some providers charge separately for:

Hidden API Fee	Industry Range	TechTo Networks
API access setup fee	₹0 – ₹5,000 one-time	₹0 (included)
Monthly API maintenance fee	₹0 – ₹2,000/month	₹0 (included)

SDK/integration support	₹0 – ₹5,000/project	₹0 (included)

Always confirm with your chosen provider whether API access is genuinely free or conditionally free (e.g., free only above a minimum monthly spend).

7. DLT Charges: What They Are and How They Affect Your Bill

What Is DLT and Why Does It Add to Your SMS Cost?

TRAI's Distributed Ledger Technology (DLT) framework, mandated since March 2021, is a blockchain-based registry for all commercial SMS in India. Every message sent must be verified against the DLT ledger before the carrier delivers it to the recipient. This verification step carries a processing charge — currently approximately ₹0.025 per SMS — that is passed on to the sender by the telecom operators.

This is not a provider markup. It is a regulatory cost that every business in India must pay, regardless of which SMS provider they use.

How DLT Charges Are Billed

Model 1 — Included in per-SMS rate (transparent):The provider embeds ₹0.025/SMS DLT charge into their quoted per-SMS rate. When they say "₹0.18/SMS," you pay ₹0.18/SMS — total. This is how TechTo Networks prices its services.

Model 2 — Billed separately (hidden):The provider advertises ₹0.15/SMS but then adds ₹0.025/SMS DLT charge to your invoice separately. Your actual cost is ₹0.175/SMS — 16.7% higher than the headline rate. This is a common practice among low-cost providers as a way to advertise misleadingly low rates.

How to spot Model 2 providers: Ask specifically "Is the ₹0.025 DLT surcharge included in your quoted rate?" If they hesitate or say "it depends," it is not included.

DLT Registration Fees (One-Time)

In addition to the per-SMS DLT processing charge, businesses must pay one-time DLT registration fees to the telecom operators:

Registration Type	Operator Fee	Who Manages It
Principal Entity (PE) Registration	₹5,900 per operator	TechTo Networks manages for clients
Sender ID (Header) Registration	₹0–₹500 per header	TechTo Networks manages for clients
Template Registration	₹0 (free on most operators)	TechTo Networks manages for clients
Annual DLT Renewal	₹5,900/year per operator	TechTo Networks reminds and manages

TechTo Networks includes DLT onboarding and template management support as part of the service — no additional professional fees charged.

8. Hidden Costs in Bulk SMS Pricing — And How to Avoid Them

The bulk SMS industry in India has a significant transparency problem. Many providers advertise very low per-SMS rates that balloon into much higher actual costs once all charges are considered. Here are the 10 most common hidden costs to watch for when evaluating any bulk SMS provider:

Hidden Cost #1: Unpublished DLT Surcharge

What happens: Provider advertises ₹0.12/SMS. Invoice arrives at ₹0.145/SMS.Reason: ₹0.025/SMS DLT charge billed separately without prior disclosure.How to avoid: Ask explicitly: "Is your DLT surcharge of ₹0.025 included in the quoted rate?"

Hidden Cost #2: Setup and Onboarding Fees

What happens: Provider charges ₹2,000–₹10,000 for account activation, KYC processing, or "platform onboarding."Reason: Many providers treat account setup as a revenue opportunity.How to avoid: Confirm "Is there any setup fee, onboarding fee, or activation charge?" before signing up.TechTo Networks: ₹0 setup fee. Free account activation.

Hidden Cost #3: Credit Expiry Without Warning

What happens: You buy a ₹5,000 credit pack. Three months later, half your credits expire because you didn't read the fine print about a 90-day validity window.Reason: Providers monetize unused credits by setting short expiry windows.How to avoid: Ask for validity period in writing. Prefer providers with 6–12 month or lifetime credit validity.TechTo Networks: 6–12 month validity on all plans, with enterprise packs offering annual validity.

Hidden Cost #4: Minimum Recharge Requirements

What happens: You need ₹1,500 worth of credits. Provider's minimum recharge is ₹5,000. You overpay by ₹3,500 and risk expiry.Reason: Artificial minimum orders increase provider revenue.How to avoid: Choose providers with ₹500–₹1,000 minimum recharge for startups.TechTo Networks: Plans start from small volumes suitable for startups and testing.

Hidden Cost #5: API Access Fees

What happens: The "free" API access turns out to be free only up to 100 API calls per day. Beyond that, you're charged per API call or forced into a paid developer tier.Reason: Monetizing developer usage beyond basic access.How to avoid: Ask: "Is API access completely free with no call limits for paid SMS accounts?"

Hidden Cost #6: Fake Low Rates via Grey Routes

What happens: Provider offers ₹0.06/SMS — sounds incredible. You send 5 lakh messages. Only 2.5 lakh are actually delivered; the rest are dropped or fake delivery reports are generated.Reason: Grey route providers submit only 50–70% of messages to carrier SMSCs and pocket the difference.How to avoid: Any rate below ₹0.10/SMS in 2026 for DLT-compliant routes is a red flag. Test delivery before committing large budgets.

Hidden Cost #7: Multi-Part SMS Billing Surprise

What happens: You write a 185-character message. You're billed for 2 SMS credits per recipient.Reason: Any message over 160 characters (ASCII) or 70 characters (Unicode) becomes a multi-part SMS — each part billed as a separate credit.How to avoid: Always count characters before sending. Keep templates under 160 characters (ASCII) or 70 characters (Unicode). Use an SMS character counter tool.

Hidden Cost #8: Dedicated Sender ID Monthly Fee

What happens: You assumed your branded sender ID (TECHTO, BANKAX) was included. It's a ₹500–₹1,500/month add-on.Reason: Dedicated sender IDs require exclusive carrier-side registration.How to avoid: Ask specifically: "Is a dedicated 6-character branded sender ID included in this plan?"

Hidden Cost #9: Paid Technical Support

What happens: Your DLT template gets rejected at 11 PM the night before a major campaign launch. The provider's only support option is a ticket that gets answered in 48 hours.Reason: Free support is limited to business hours; real-time support requires a paid tier.How to avoid: Test support responsiveness before committing. Call or WhatsApp their support number at an unusual hour.TechTo Networks: 24/7 support included in all plans.

Hidden Cost #10: International SMS Surcharges

What happens: You have 5% of your customer base outside India. Your provider's international rate is ₹5/SMS — 25x your domestic rate — and this was never mentioned upfront.Reason: International A2P SMS is genuinely more expensive, but the markup varies wildly.How to avoid: If any portion of your user base is international, ask for the provider's per-country international SMS rate sheet before signing up.

13. International Bulk SMS Rates from India

For businesses with customers or users outside India, bulk SMS rates are dramatically higher than domestic rates. International SMS pricing is determined by the destination country's telecom regulations, local carrier termination fees, and the provider's international carrier agreements.

International SMS Rates from India — Reference Rates 2026

Destination Country	Approx. Rate per SMS	Notes
USA / Canada	₹2.50–₹4.00	High carrier fees; TCPA compliance required
UAE / Gulf Region	₹3.00–₹5.50	Saudi Arabia higher than UAE
UK	₹2.50–₹4.00	GDPR compliance required
Singapore	₹3.50–₹5.00	PDPA compliance
Bangladesh	₹2.00–₹3.50	Improving carrier connectivity
Southeast Asia (avg)	₹3.00–₹5.50	Country-specific variance
Africa (avg)	₹4.00–₹8.00	Highest carrier termination fees

Key Note: International SMS from India does not use the TRAI DLT framework — it uses the destination country's A2P SMS regulations. Ensure your provider is compliant with TCPA (USA), GDPR (Europe), PDPA (Singapore) etc.

14. How to Get the Best Bulk SMS Rate in India

Getting the best bulk SMS rate is not just about negotiating the lowest per-SMS number — it is about maximizing the total value you receive for your spend. Here are ten actionable strategies:

1. Commit to annual volume for the deepest discount.If your SMS usage is predictable, committing to a 12-month volume pack instead of PAYG can reduce your per-SMS cost by 35–50%.

2. Always ask if DLT charges are included.Never compare rates without confirming whether the ₹0.025 DLT surcharge is embedded or added separately. Two providers quoting ₹0.15/SMS and ₹0.18/SMS may both end up at ₹0.18/SMS after DLT — making them equivalent.

3. Negotiate on total commitment, not just per-SMS rate.Providers will often give deeper discounts for prepayment (e.g., paying 6 months upfront) than for volume commitments alone. Offer to prepay in exchange for better rates.

4. Separate your SMS types and price them separately.Do not bundle promotional, transactional, and OTP SMS into a single plan if your provider offers separate pricing for each. OTP at 10% of your volume should not inflate the cost of your 60% promotional volume.

5. Test before you buy large.Use free trial credits to test delivery speed, DLR accuracy, and support quality before committing to a large prepaid pack. Cheap SMS that doesn't deliver is infinitely more expensive than reliable SMS at a fair rate.

6. Watch for credit expiry traps.Negotiate credit validity upfront. Every rupee in expired credits is a 100% loss. Prefer providers with 12-month credit validity.

7. Ask about reseller pricing if your volume warrants it.At volumes above 50L SMS/month, some providers offer reseller-tier pricing — essentially wholesale rates — even if you're not reselling. Worth asking.

8. Keep messages under 160 characters to avoid multi-part billing.Every character over 160 (ASCII) doubles your SMS credit usage. Audit all templates for length before approving them in DLT.

9. Use regional language templates only where necessary.Unicode SMS (Hindi, Tamil, etc.) have a 70-character limit per SMS part — easily generating 2–3 SMS credits for a single message. For mixed audiences, consider offering an English alternative.

10. Request itemized invoices.Ask for invoices that break down SMS volume by type (promotional/transactional/OTP), DLT charges, multi-part charges, and any add-on fees separately. Itemized billing lets you spot anomalies and negotiate smarter at renewal.

15. Bulk SMS ROI: Is the Cost Worth It?

At ₹0.14 per promotional SMS, one question businesses rightly ask is: does bulk SMS actually generate enough return to justify the spend? The answer, backed by India-specific data, is emphatically yes.

Bulk SMS vs Other Digital Marketing Channels in India — ROI Comparison

Channel	Average Cost per 1,000 Reach	Average Open Rate	Average Conversion Rate	Typical ROI Multiple
Bulk SMS	₹140–₹250	95–98%	5–8%	8–15x
Email Marketing	₹50–₹200	20–35%	2–4%	3–8x
WhatsApp Business	₹350–₹800	85–95%	6–10%	5–12x
Facebook/Instagram Ads	₹400–₹1,500	1–3% CTR	1–3%	3–6x
Google Search Ads	₹1,000–₹5,000	High intent	3–8%	4–10x
Push Notifications	₹20–₹100	5–15%	1–3%	2–5x

Key ROI Factors for Bulk SMS

Why SMS outperforms on open rate:SMS arrives directly in the recipient's message inbox — no algorithm decides who sees it, no spam filter silently redirects it. India's SMS open rate of 95–98% versus email's 20–35% means a far higher proportion of your spend actually reaches active attention.

Why SMS works in rural and semi-urban India:Unlike WhatsApp, social ads, or push notifications, SMS works without an internet connection. For businesses selling in Tier-2, Tier-3, or rural India — where 4G penetration is growing but still inconsistent — SMS remains the only guaranteed-reach channel.

Real example: Ecommerce flash sale campaignA D2C apparel brand sends 1,00,000 promotional SMS at ₹0.14/SMS = ₹14,000 campaign cost.Open rate: 96% = 96,000 messages readCTR: 6% = 5,760 users click the linkConversion rate: 4% = 230 purchasesAverage order value: ₹1,200Revenue generated: ₹2,76,000ROI: (₹2,76,000 - ₹14,000) / ₹14,000 = 19.7x return on spend

17. Frequently Asked Questions: Bulk SMS Rates in India

What are the current bulk SMS rates in India in 2026?Bulk SMS rates in India in 2026 range from ₹0.10 to ₹0.35 per SMS depending on message type, volume, and provider. Promotional SMS starts as low as ₹0.10/SMS for high-volume enterprise senders and ₹0.18/SMS for small businesses on PAYG. Transactional SMS ranges from ₹0.15 to ₹0.28/SMS. OTP SMS ranges from ₹0.15 to ₹0.35/SMS with sub-2-second delivery. TechTo Networks offers promotional SMS from ₹0.10/SMS and transactional/OTP from ₹0.14/SMS at enterprise volumes, with all DLT charges included in the quoted rate.

What is the cheapest bulk SMS rate in India?The cheapest promotional bulk SMS rates in India in 2026 start at ₹0.10–₹0.12/SMS for enterprise volumes above 10 lakh SMS per month on DLT-compliant Tier-1 routes. Be cautious of advertised rates below ₹0.10/SMS — these typically use non-DLT grey routes, deliver only 50–70% of messages successfully, and generate fake delivery reports. The real-world cheapest reliable rate on a DLT-compliant platform in 2026 is approximately ₹0.10–₹0.11/SMS for promotional at high volume.

Are DLT charges included in bulk SMS rates?It depends on the provider. TRAI mandates a DLT processing fee of approximately ₹0.025 per SMS that all providers must pay to the telecom operators. Some providers (including TechTo Networks) embed this in their quoted per-SMS rate — what you see is what you pay. Others advertise a lower rate and then add the ₹0.025 DLT charge separately on your invoice. Always ask: "Is the DLT surcharge of ₹0.025 included in your quoted rate?"

What is the difference in rates between promotional and transactional SMS?Transactional SMS costs approximately 25–40% more than promotional SMS for the same volume. The premium reflects higher delivery priority (transactional messages are processed before promotional ones in carrier queues), 24/7 delivery capability (promotional is restricted to 9 AM–9 PM), and the ability to reach DND-registered numbers. For example, at TechTo Networks: promotional at 1 lakh/month = ₹0.14/SMS; transactional at 1 lakh/month = ₹0.18/SMS.

How many SMS can I send for ₹1,000?At TechTo Networks' current rates:

• ₹1,000 at ₹0.18/SMS (promotional PAYG) = approximately 5,555 SMS

• ₹1,000 at ₹0.22/SMS (transactional PAYG) = approximately 4,545 SMS

• ₹1,000 at ₹0.28/SMS (OTP PAYG) = approximately 3,571 OTPs At volume pricing (1 lakh/month):

• ₹1,000 at ₹0.14/SMS = approximately 7,142 promotional SMS

Is there a minimum recharge for bulk SMS in India?Minimum recharge requirements vary by provider. Some require ₹5,000–₹10,000 minimum. TechTo Networks' entry plans start from small volumes accessible to startups and individual developers. Always check minimum recharge requirements and credit expiry terms before committing.

Do bulk SMS credits expire in India?Most providers set expiry windows on prepaid credits — typically 30 days for monthly packs and 6–12 months for larger packs. TechTo Networks offers 6-month validity on Starter and Growth plans and 12-month validity on Business, Professional, and Enterprise plans. Credits do not auto-renew; unused credits at expiry are forfeited unless the plan is renewed.

Is GST charged on bulk SMS services in India?Yes. Bulk SMS services in India are subject to 18% GST (CGST + SGST or IGST depending on supplier and recipient location). This is in addition to the per-SMS cost. All prices quoted by TechTo Networks are exclusive of GST unless stated otherwise. Budget for 18% on top of quoted SMS rates.

Can I send bulk SMS in Hindi and regional languages? What is the cost?Yes — Unicode bulk SMS supports Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Marathi, Punjabi, and other languages. Unicode SMS has a character limit of 70 characters per part (versus 160 for English ASCII). Messages exceeding 70 characters are billed as 2 SMS credits; exceeding 140 characters as 3 credits, etc. The per-credit rate is the same as English SMS, but the per-message effective cost is higher for longer regional language messages due to multi-part billing.

What is the cheapest way to send OTP SMS in India?The most cost-effective OTP SMS strategy in India involves: (1) Choosing a provider with DLT-managed OTP at competitive rates (TechTo Networks from ₹0.18/OTP at enterprise volume), (2) Committing to annual volume for 35–50% discount versus PAYG, (3) Ensuring multi-channel fallback (Voice OTP) is included in rate rather than charged separately, and (4) Verifying that DLT charges are included in the quoted rate. For startups, 2Factor offers PAYG from ₹0.15/OTP but without managed DLT support.
