- Check your balance to see if you have enough credit or haven't gone over your monthly usage. It's easily done and your network provider could be blocking further calls and messages because of this.
- Look to see if your inbox is full. Some mobile phones stop you from making and receiving texts if this is the case.
- Try to make a phone call from your phone. If the phone call doesn't go through, check that you have enough reception. Turn your phone off and then on again and try sending a message/making a call from another area.
- If you can make a phone call, go to your phone's message settings and see if the SMS service centre number is correct with the ones shown below:
|Network Provider||SMS Service Centre Number|
|O2 Pay As You Go||+447802092035|
- If you've recently changed phones you may have to wait up to 48 hours for the network to change all the settings.
- The next step is to try your SIM card in another compatible phone. If you're able to send a message, it means the fault is with your mobile phone and you'll need to put it in for repair.
- If you still can't send an SMS then there's a problem with your SIM card. You can get a replacement in-store or by calling your provider who can send you one in the post.
- Sometimes masts can become faulty, which will affect your coverage. When you ring your network, check to see if any have been affected in your area.
