If you are experiencing issues with being able to send / receive SMS from your Mobile Handset, we recommend trying the below troubleshooting:
Symptom: Unable to send or receive an SMS
Step 1: Check that the handset is showing reception bars.
Step 2: Reboot your handset. Turn handset OFF – remove SIM Card for up to 5 minutes – reinsert SIM Card – turn handset ON.
Step 3: If the above reboot does not resolve the issue, if possible, test your SIM Card in another handset as the issue may be related to the handset and not the SIM Card or network.
