All I am transitioning my 3 lines from 10 GB simple choice to One in a week. I have to phones with 10GB and a Sync Drive with 2GB. I will never use more than a few GB off my phone and would like a way to give more DATA to the sync drive as my wife connects to it on long drives with her tablet. Any ideas?
You cannot gift data to another line each line on One has an unlimited data Supply and devices that tether to your data like snuck up cannot be gifted data however the sync up will tether to tour phone up to 10 gigabyte LTE if you have that added to your One plan.
