I am planning on buying an ipad mini 4 wifi + cell or ipad pro 7.9 for traveling purposes
I am not a good tech person. I would like to know if I buy either an ipad mini 4 or a ipad pro 7.9 what is the best way to use the SIM card when I travel overseas without incurring in roaming charges. And when I return to the US from my trip I can get it connected to the carrier that I have with my iphone 6 (Verizon) or I need to get it connected to another carrier instead of Verizon?, and have the option to change carriers every time I travel overseas. I need the GPS feature (location) every time I take pictures so the information of the location where I took the picture is already in so I do not have to write the info afterwards. Please advise.
