Hi I was dealing with somebody on the live chat but got cut off and it has now closed. I am unable to receive any signal in any location. My phone was tested in store and they said not an issue with the phone so gave me a replacement sim card. I have activated this, waited at least an hour, restarted my phone several times and it made no difference. I have also tried removing and re-inserting this sim card (it is definitely fitted correctly) I am paying around £30 every month and tied into a contract for a phone that doesn't work! It has resulted in being unable to make emergency calls. Are you able to help please?
