Hi Everyone, I looked into the spec of the Sprint 5s and it seems to contain all bands that an AT&T 5s contains. Does it mean that I can use the Sprint 5s with the AT&T network. My company only uses Sprint so I may have to buy the Sprint 5s but wonder if one day I port out the line to AT&T, can I still use the Sprint 5s on AT&T. Thanks in advance for any help and comment. Have a great weekend Btw similarly, can a Verizon 5s be used on AT&T since it also contains all the bands and it also has a SIM slot? Thanks again.
