Welcome to the Community, I'm so sorry to learn about the problem you're experiencing with your mobile at the moment.
Firstly, I'd recommend logging into your My Virgin account and checking that nothing is wrong, you can check that [here]. If that's all looking good, try taking a look at our [coverage checker] to see if there are any problems in your local area
Do you have airplane mode switched on at the moment? If not, we'd like to reconnect to the network manually. Let me know what handset you've got and I'll guide you through that if you like.
Look forward to hearing from you and getting this sorted
Hi I've done that, but it has made no difference. The signal is greatly improved when I leave my home area and have spoken to other people in the area on EE who are also having the same problems. However EE claim there is no problem in the area.
