My phone is not receiving calls or enabling me to make calls using the network.

Calls not connecting

I'm experiencing the same problem. I haven't been receiving phone calls, nor can I make calls. While I get SMS messages sporadically, I also need to turn off my voicemail because I can't listen to messages without being able to call Three. How can I resolve this? The shops tell me to reach out to customer service, but I need a SIM that allows outgoing calls! I've tried the SIM in four different phones, including some that my friends use daily without problems, so I know the issue isn't with the phones.

Hello, welcome to the Three Community.

Do you have the issue in all locations? Or have there been places where calls have been working? 

Pete.

Hi @Gilly03,

Sorry to hear you've been having trouble with making and receiving calls. If this problem started very recently within the last two weeks or so, this could relate to our 3G switch off. Please have a look at our advice on How to ensure your phone is ready for the 3G switch off and let me know if this helps.

Thanks,
Jonathan
