So I moved to a new area and the building I work in gets so-so reception from at&t. I want to port my phone number to verizon and my employer is willing to reimburse me only for the voice charges and the ETF fee. However, I'd like to keep my iPhone 4 (at&t). My employer has a discount through at&t premier and when I went to their website, it seems that I can get a data only plan with unlimited data and 200 sms for $33 plus tax. When I choose devices, there's a number of smartphones, and I chose a refurbished samsung focus. If I buy this as a data only device, can I then cut the sim card and put it in my iPhone 4? Thanks in advance.
