I don't know if this is the correct forum page, Mods please relocate if its not. I have 4 voice/data lines with Tmo and my family is currently only using 3 of them, the cool thing about the lines is that all of them have a line of 10gb/mo. So that 4th line that isn't being used... I was wondering if I could pop that sim card into a cellular iPad and the data will work... I really don't want to call Tmo and have them take a look at my acct and change that voice/data line just to data. Just in case I wanted to pop that back into a phone and be it voice and data. Can anyone confirm this for me? Maybe put their Tmo sim card from their phone to a iPad with cellular?
