3 months ago I obtained a T-mobile pre-paid plan to stay connected while in the US ($15 per month). Now I’m back to my country (outside of T-mobile network) but I want to keep the same number for when I get back to the US next year. I have recently paid the monthly fee while here in Colombia but I want to reduce the fee because I’m using my local sim card. How can I do that?
I have heard about connecting the number to Google Voice but I’m not sure if that’s the most effective and less expensive option to keep my US phone number.
