Don't know how else to ask. I have a semi similar issue. Got a new phone, iPhone 5SE. My old phone is iPhone 4. Never outright said this but I asked which iOS this phone had because my phone could get iOS 9. I didn't have my old phone with me. She never said I would need a new SIM card but I do! What can I do? I don't have time to go back probably until Friday and I want my new phone fully useable today!
