Bulk SMS that reaches everyone
in Tanzania.

The sender ID is the name your customer sees when the SMS arrives — e.g. "NMB" instead of "+255 7XX XXX XXX". A branded sender ID looks professional, doesn't get filed under spam, and confirms the message is legitimately from you. SanyaSMS registers your sender ID with TCRA (the Tanzanian regulator) for free — usually approved within 2–3 working days. While we're waiting, your SMS goes out under the fallback ID "INFO" so nothing blocks.

All Tanzanian mobile operators: Vodacom, Airtel, Tigo, Halotel, Smart, Zantel, and TTCL. Same price across all of them (TZS 18/SMS). We can also route international SMS — email us for rates by country.

Typical end-to-end delivery is under 5 seconds. We give you real-time delivery receipts in the dashboard so you can see what was delivered, what failed, and why.

Yes — REST API with API-key auth, JSON payloads, idempotency keys, and webhook delivery receipts. Used in production by ~80 businesses for OTPs and transactional sends. Documentation at app.sanya.tz/docs.

No. Once you top up, the credits sit on your account until you use them. Unlike most TZ SMS providers, we don't expire balances after 6 / 12 months.

From the SanyaSMS dashboard, pick a package (e.g. 1,000 SMS for TZS 18,000), and pay via SanyaPay — which accepts M-Pesa, Tigo Pesa, Airtel Money, Halopesa, bank cards, and direct bank transfer. Credits land on your account instantly when payment confirms.

No. SanyaSMS is built into every Sanya OS workspace — same dashboard, same balance, same sender ID. The standalone app.sanya.tz exists for businesses that only want SMS without the rest of the business OS.

Yes, but with rules. TCRA requires sender ID registration, prohibits sending between 21:00–07:00 (we enforce this), and requires opt-out instructions on marketing SMS. We handle the compliance side so you don't have to think about it.
