I have had no phone signal for 3 days now. I have been on to 48 and all they said was it was a faulty and they sending out a new one. But until then I cannot make or recieve calls or texts. As far as I am aware the sim hasn't even been dispatched. Has this happened to anyone else? I have tried everything possible and do not get any signal. Ive tried it in 2 other phones and no signal so must be the sim card.
