Your Samsung messages show a red exclamation mark, get stuck on "Sending," or fail with an error. Whether it's SMS texts or messaging apps like WhatsApp failing to send, a message delivery fault disrupts communication. Call 0723763173 — our Nairobi team handles both software and hardware causes.
Why Are Samsung Messages Not Sending?
For SMS:
- No network signal or SIM not registered on the network
- Wrong SMSC (SMS Centre) number in SIM settings — this is a common issue after switching networks in Kenya
- Message centre number missing: go to Phone app › Settings › More Settings › Text Messages › Message Centre and confirm it's set
- SIM card damaged or not seated properly
For internet-based messaging (WhatsApp, Telegram, etc.):
- No internet connection — check data or WiFi
- App-level fault — clear app cache or reinstall
- Incorrect date/time causing SSL errors that block message delivery
- Account or server issue on the messaging platform side
Checking Your SMSC Number in Kenya
Safaricom SMSC: +254722000000 Airtel Kenya SMSC: +254733100000
Enter these in your message settings if SMS delivery is failing. This resolves message sending failures for many Kenyan Samsung users after a network or SIM change.
Hardware Causes
If SMS fails despite correct settings and good signal, the SIM tray, SIM card, or modem hardware may be at fault. We test and repair these at our Nairobi workshop.
