At the time being I am an international student from Norway living in the US. In my physical SIM-slot on my Xs is my Norwegian SIM-card who gives me free international roaming as well as texts and calls. To call text/within the US, I use Google Voice/Hangout and their free service. The advantage of this is not having to pay for double data etc, but the disadvantage of this is not being able to register with services such as Venmo, because the Google Voice number is recognized as a landline number. Is there a work around or another way to get this working?
