First, check whether your handset is configured correctly. With our handy, interactive guide you will quickly see whether you have used the correct settings for your handset.
Having problems? Then try this:
- Switch off your handset and remove the battery (if possible). Place the battery back in your handset and then switch it on again.
- Still having problems? Place your SIM card in another handset and check whether it works there. Then place your BASE SIM card back in the original handset, test it again and check whether your text message has been sent/received.
