I have a 4g/LTE sim in my iPad4 and an iPhone 5s full price Tmobile bought from Apple online store. I need to get buy a couple of weeks before going on a long vacation so thinking to use the 4g/lte sim in my iPhone 5s with Google voice and Talkatone. Will my iPhone 5s get the 4g/lte service from the Att sim? I thought I would ask first before cutting it down.

Thanks

Thanks. Just realized th Att is the giant full size sim, if I cut it down to Nano sim some gold part will have to go. Will that work or affect the lte speed?
