The problem

SMS OTP is broken in this region.

Every fintech in the Middle East and Africa relies on SMS one-time passwords. They fail constantly — and nobody talks about it.

Messages arrive late — or not at all

Carrier routing across African telecom networks is fragmented. OTPs expire before users receive them, killing conversion at the worst possible moment.

🔓

SIM swap fraud is rampant

Nigeria and South Africa lead globally in account takeover via SIM swap. An OTP sent to a stolen number is worse than no verification at all.

💸

SMS costs are climbing fast

Global CPaaS providers charge premium rates for African routes. At scale, SMS OTP becomes a significant and growing line item on every fintech's P&L.

📱

No good alternative — until now

Silent Network Authentication exists in the US, UK, and Europe. The infrastructure for UAE and Africa exists. Nobody has built the developer layer on top of it.

How it works

Three layers. One API.

Simba sits between your app and the carrier network. Your users never see it working — that's the point.

01 OAuth orchestration

Silent carrier handshake

Your app passes a phone number. Simba initiates an Authorization Code flow with the carrier's CAMARA API — entirely over the device's mobile data connection. No user input, no waiting.

02 Carrier routing

Intelligent multi-carrier routing

Simba detects the carrier from the number prefix and routes to the optimal network. If SNA isn't supported, it falls back to SMS OTP automatically — your code never changes.

03 Fraud detection

Real-time fraud signals

Every verification check includes SIM swap recency, request anomaly detection, and phone number reputation. Know if a number was swapped in the last 24 hours before approving a transaction.

For developers

Integrate in minutes, not weeks.

verify.py
# Verify a phone number silently
import simba

client = simba.Client(
  api_key="sk_live_..."
)

result = client.verify(
  phone="+971501234567",
  channel="silent",
  fallback="sms"
)

# result.verified → True
# result.channel → "silent"
# result.sim_swap → False
# result.latency → 1.2s

One endpoint, every carrier

Your code doesn't know or care whether verification happened via e& UAE, MTN Nigeria, or SMS fallback. Simba handles all routing logic.

iOS & Android SDKs

Native mobile SDKs force the verification request over cellular data — the technical requirement for silent auth — without you writing a single line of network code.

SIM swap signal included

Every verification response includes a SIM swap recency flag. Pass it to your risk engine, or let Simba block suspicious verifications automatically.

Markets

Built for mobile-first economies.

CAMARA-certified carrier APIs are live across our target markets. We're the missing developer layer.

🇦🇪

UAE

e& (Etisalat) holds three GSMA CAMARA certifications — the only operator in MENA with this credential. The infrastructure is ready. The product layer isn't built yet.

e& — CAMARA certified du — coming
🇿🇦

South Africa

Three carriers — MTN, Cell C, and Telkom — launched CAMARA Number Verification and SIM Swap together. A 24% surge in digital banking fraud makes this an urgent market.

MTN — live Cell C — live Telkom — live

Nigeria

MTN Chenosis exposes SIM Swap and Number Verification APIs across Nigeria. Home to Africa's most active fintech ecosystem and highest SIM swap fraud rates.

Ghana · Kenya · Uganda

MTN's Chenosis platform covers 18 African markets. As carriers achieve CAMARA certification, Simba expands automatically. Same product, new carrier connector per market.
