I know this has probably been asked a million times but I have terrible service with AT&T and don't wanna take ages loading pages to look for answers. Can I take my AT&T iPhone 6 Plus with me to Verizon? Or not?
No. Verizon won't activate a phone that they don't have a SKU for in their own system. You can put your sim card in there and it won't make a difference. You would have to call them and activate the phone.
