Reaching African users by SMS, OTP and USSD: ten verified API options compared
Ten communication APIs in the Wycord registry cover SMS, OTP, USSD and voice for African apps. Here is how they compare and when to pick each one.
SMS still converts better than push notifications for user verification across most African markets. OTP via SMS is the standard for account sign-up, fund transfers and KYC flows. USSD extends that reach to feature phones, which remain a large share of active devices across Nigeria, Kenya and Tanzania.
The Wycord registry returns ten communication APIs when filtered to the SMS category. This post maps each option by geography, channel and best-fit scenario so you can choose without reading ten sets of docs.
The ten providers at a glance
Nigeria-first
- Termii (wycord.com/resource/termii): SMS, OTP, voice and USSD. Nigeria only. Built-in DND-aware routing, which matters for OTP delivery on Nigerian carriers. Pricing is NGN-denominated and per-message. Developers consistently cite documentation quality as a strength.
- BulkSMS Nigeria (wycord.com/resource/bulksms-nigeria): SMS only, Nigeria only. Accepts local payment methods and prices in NGN. Right for teams that need one channel in one country and want to pay locally.
- KudiSMS (wycord.com/resource/kudisms): A broader CPaaS for Nigeria covering SMS (promotional, transactional and OTP), email, WhatsApp Cloud and voice (pre-recorded and text-to-speech). Free signup, credit-based billing.
- HollaTags (wycord.com/resource/hollatags): USSD specialist. Deep integration for Nigerian banks and enterprise USSD workflows. Not a self-serve product. If you are building a USSD menu for a bank or regulated financial app, this is the category leader for Nigeria.
Pan-African and multi-country
- Africa's Talking (wycord.com/resource/africas-talking): SMS, USSD and voice across multiple African markets. USSD coverage in Nigeria confirmed across all four major operators: MTN, Airtel, Glo and 9mobile. Official SDKs available for Python, Node.js and other runtimes. The only provider in this list with first-party SDK coverage at this breadth.
- Sendchamp (wycord.com/resource/sendchamp): Multi-channel in a single API. SMS, WhatsApp, voice, email, USSD and OTP. Lagos-headquartered. Pay-as-you-go with free account signup. Covers Nigeria and other African markets. WhatsApp Business delivery is a first-class channel, not an afterthought.
- Tingg by Cellulant (wycord.com/resource/tingg-by-cellulant): Primarily a payments platform covering 24+ African markets, with SMS and OTP as part of its customer engagement layer. Right if you are already using Cellulant for collections and want messaging in the same contract.
West Africa beyond Nigeria
- Arkesel (wycord.com/resource/arkesel): Ghana-based. Covers Ghana, Nigeria, Tanzania and South Africa. Channels: SMS, USSD, voice, OTP, WhatsApp Business and email. Free signup, pay-as-you-go. The default choice if you are building a Ghana-primary product and need cross-border reach.
- Hubtel (wycord.com/resource/hubtel): Ghanaian fintech founded in 2005 as SMSGH. SMS and USSD sit alongside mobile money collection and card payments in the same API. Some features require licensing approval. Worth considering if you are building a Ghana product that combines communications with payments.
East Africa
- Beem Africa (wycord.com/resource/beem-africa): Tanzania-origin. SMS, OTP, USSD, airtime and voice. Claims 22+ African regions and ISO 27001 compliance. Docs are live. A natural candidate for East Africa-focused products looking for a locally-rooted provider.
Choose by channel
SMS only: BulkSMS Nigeria (local NGN pricing, Nigeria), Arkesel (multi-country from Ghana), Africa's Talking (pan-African).
OTP with Nigerian DND routing: Termii. DND-aware routing is built into the API design, not a support ticket.
OTP with channel fallback (SMS fails, fall back to WhatsApp): Sendchamp or KudiSMS.
USSD menus: Africa's Talking (all four Nigerian operators confirmed), HollaTags (bank-grade enterprise), Termii, Sendchamp.
Multi-channel in one API (SMS + WhatsApp + Voice + Email): Sendchamp, KudiSMS, Arkesel.
Ghana-primary product: Arkesel (comms only) or Hubtel (comms plus mobile money).
East Africa or Tanzania: Beem Africa.

Three things the docs do not tell you upfront
DND lists in Nigeria quietly kill delivery. Nigerian carriers maintain Do Not Disturb registries that silently drop promotional SMS without a delivery failure code. Termii's API is designed around this. For any OTP or transactional route, confirm your provider distinguishes between promotional and transactional channels at the routing level, not just at the label level.
USSD short codes are operator-specific. Africa's Talking confirms multi-operator support in Nigeria, but you still need to acquire a short code per operator and test sessions separately. Session timeout behavior also differs. Budget testing time across all operators before launch.
WhatsApp Business as OTP fallback is viable in Nigeria. WhatsApp penetration in Nigeria is high enough that it works as a secondary delivery channel when SMS fails. Sendchamp and KudiSMS both support this pattern in a single API call. Factor it into your OTP retry logic.
The SDK and MCP layer
Africa's Talking has official SDKs. The Wycord registry also includes community-built wrappers: an africastalking-python library and an africastalking-nodejs SDK for Node, both with documented coverage.
For AI-agent use cases, the registry includes two MCP servers: an Africa's Talking SMS MCP and a Termii MCP. These let AI agents send SMS and trigger OTP flows directly without building HTTP wrappers.
