Q1: How many characters can I send in a Unicode SMS?

A: The first Unicode SMS segment can contain up to 70 characters. If your message is longer, it will be split into multiple segments, with each additional segment containing 67 characters. For example, a 140-character message would consume 3 credits (70 + 67 + 3 characters).

​

Q2: Which languages are supported by TechTo Networks?

A: We support all major Indian languages including Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Marathi, Punjabi, Odia, Assamese, and Urdu. We also support international languages like Arabic, Chinese, Russian, Thai, Japanese, and Korean. Emojis and special symbols are also supported.

​

Q3: Is Unicode SMS more expensive than regular SMS?

A: Unicode SMS has a slightly higher per-credit cost due to reduced character capacity per message. However, the significantly higher engagement rates and better conversion typically result in a better return on investment, especially when targeting regional language audiences.

​

Q4: Can I mix English and regional languages in the same message?

A: Yes, but the entire message will be treated as Unicode SMS if it contains even a single non-GSM character. This means character limit will be 70 per segment instead of 160. We recommend keeping messages in a single language when possible for efficiency.

​

Q5: How do I calculate the cost of my Unicode SMS campaign?

A: Our platform features a real-time credit calculator. As you type your message, it automatically shows how many characters you've used and how many credits the message will consume. You can also use our online calculator tool before starting your campaign.

​

Q6: What's the delivery rate for Unicode SMS?

A: TechTo Networks maintains a 98%+ delivery rate for Unicode SMS across all Indian mobile networks. Delivery rates depend on factors like number validity, network connectivity, and handset memory. Our delivery reports provide complete transparency.

​

Q7: Can I schedule Unicode SMS campaigns for future delivery?

A: Yes, you can schedule campaigns for any future date and time. This is perfect for festival greetings, birthday wishes, appointment reminders, and time-sensitive promotions. You can also set up recurring campaigns for regular communications.

​

Q8: How do I handle special characters like rupee symbol, emojis, or mathematical symbols?

A: All special characters are automatically handled when you select Unicode encoding. Simply type or paste your message with special characters, and our system will encode it correctly. The character counter will show you the exact credit consumption.

​

Q9: Is Unicode SMS supported on all mobile networks and devices?

A: Yes, Unicode SMS is supported by all major Indian mobile networks (Jio, Airtel, Vi, BSNL) and virtually all mobile devices manufactured in the last 15 years. Older feature phones may have limited font support for certain scripts, but smartphones display all languages perfectly.

​

Q10: What's the difference between Unicode SMS and Flash SMS?

A: Unicode SMS refers to the character encoding that allows multi-language support. Flash SMS refers to a delivery method where messages appear on the screen immediately without going to the inbox. You can send Unicode Flash SMS—the two features are independent.

​

Q11: How quickly are Unicode SMS messages delivered?

A: Most Unicode SMS messages are delivered within 5-10 seconds during normal network conditions. Bulk campaigns are throttled to comply with operator guidelines but typically complete within minutes. Exact delivery time depends on network load and recipient location.

​

Q12: Do I need technical knowledge to send Unicode SMS?

A: No technical knowledge is required. Our web interface is designed for easy use—simply type your message, select recipients, and send. However, we also provide comprehensive API documentation for developers who want programmatic integration.

​

Q13: Can I track which recipients received and opened my Unicode SMS?

A: You can track delivery status (delivered, failed, pending) through our delivery reports. However, SMS doesn't support read receipts like messaging apps. You can track link clicks by using our URL shortener feature to measure engagement indirectly.

​

Q14: What happens if a Unicode SMS fails to deliver?

A: Failed messages are automatically reported with failure reasons (invalid number, DND, network error, etc.). Credits for genuinely failed messages are automatically refunded to your account. You can retry failed messages with corrected numbers.

​

Q15: Is my contact list data secure?

A: Absolutely. We employ bank-grade encryption for data storage and transmission. Your contact lists and message content are never shared with third parties. We comply with Indian data protection regulations and maintain ISO 27001 certification for information security.
