Common Questions

SMS FAQ

How do I get a custom masking sender ID like "NEXEVENT"?

After purchasing credits, submit a sender ID approval request through your dashboard along with your trade license and content samples. BTRC approval typically takes 2–7 working days. We handle the entire submission for you.

What's the difference between masking and non-masking SMS?

Masking SMS show your custom brand name (e.g., "NEXEVENT") as the sender. Non-masking shows a numeric short code. Masking is required for promotional/marketing SMS and gives much higher trust + open rates.

Do credits expire?

No. Once purchased, your SMS credits never expire. Use them whenever you want — today, next month, or next year.

Can I send Bangla SMS?

Yes — full Unicode (Bangla, Arabic, Hindi, etc.) supported. One Unicode SMS = 70 characters. Standard English SMS = 160 characters. Long messages are auto-split.

Do you support international SMS?

Yes — to 200+ countries via tier-1 carriers (Twilio, Vonage, Sinch). Pricing varies by destination. Bangladesh-to-international (e.g., to a US number) starts at $0.04/SMS.

Are there any monthly fees or commitments?

No. Pure pay-per-SMS pricing. Buy credits when you need them, use them when you want. No monthly fees, no contracts, no minimums.
