We have an iPhone 5s, a Galaxy S5, and a Galaxy S3.
I've read a few threads here but still have many questions.
1) I have read elsewhere that the iPhones will work (as long as I get a GSM SIM card). But a TING rep just told me on chat that the iPhones would have to be unlocked and that only Sprint could have done that while still a Sprint customer (we came over from RingPlus). Is that true?
2) Can I simply put a GSM SIM card in to see if I get an error? How can I know if the iPhone is unlocked?
3) I have also been told that the Galaxy S5 will NOT work because it is CDMA only (even though it uses a SIM). Is THAT correct?
4) I do not believe that the Galaxy S3 even has a SIM card. Can anyone confirm?
