I upgraded my phone last week with 3 from samsung s5 to iphone 7. I rung up to have my old number transfered across but for some reason they transfered the wrong number. Rung up on thursday told it would be sorted in 48 hours but still nothing since thursday the iphone has had no service. Spoke to 3 chat they said the sim would be activated and could use it in within an hour and the number would be done in 48 hours. Couple of hours later still nothing except my samsung sim now doesnt work. Is the no service an apple problem or a 3. Has the iphone been done but i cant tell cos of the no service? Any help would be appreciated
