my Huwai phone got run over by a few cars on the highway. I found it, phone is no more good but my sim card was untouched. I have a pay-as-you-go account. My question is, can I switch my account (and same phone number) to an Iphone that uses a smaller sim card? I was given an Iphone but my sim card is too big. I absolutely NEED to keep my same phone number, and I would like to continue with my PAYG account. Please help. Thanks in advance!
