My girlfriend has an iPhone 5S through U.S. Cellular. I purchased the straight talk BYOP activation kit, when I inserted the AT&T SIM (to make sure the phone would accept a SIM from a different carrier) it told me the carrier was TFW. I was wondering if when I transfer her number will it cancel her line or the whole account on U.S. Cellular? She is under her mom's plan so there are other family members on that account. We just want to transfer her number.
I tried this as well with limited success. Okay kind of..
I've owned a Galaxy S5 for a few years, and I had to terminate my USCC Plan prematurely. I have the phone and for awhile thought you COULD NOT use the S5 on the Straight Talk network.
I proved that wrong just this weekend after rooting and making one adjustment to the phone's programming. It now works, however, I do not have LTE Access; Only 3G.
When you transitioned from USCC to Straight Talk on your iDevice, Did you get LTE Access, or no? If you did, I Might need to use the ATT Sim Card instead of the Verizon one (Because it originally was in a Verizon Prepaid device before I tested it in the S5)
