Hi... I have a Samsung A5, had a lot of spam, fraud & obscene calls so changed my phone number. Worst mistake I've ever made
.... several phone calls with technical support later and I still have no internet connection or the ability to receive text messages!! Strangely enough I can send messages, but cannot receive them. Now, what I'm told is I may need a new sim card, but would like to try and just remove and re-insert the one I have and see if that solves the problem first...…. how do I do that??
