So I currently have two phones, work & personal. I plan on keeping my personal one active just in case the work one falls through. My plan is to buy an android ATT go phone from bestbuy for $50 and put my sim in it. If this works, I can forward all sms and calls to my work phone. I have de-registered my personal number from iMessage so they should all be forwarded. Should there be any issues with switching phones with ATT? Going from iPhone5 to a cheaper android go phone. From what I've heard my plan will switch automatically. I still have an old unlimited data plan so don't want any issues.
