I use Google FI it is $20 for 1 person $35 for 2 people. This plan is pay for the data you use above a certain amount. It depends on your usage habits, I rarely go above & then it is only a few dollars. (I use wifi whenever I can, which I would advise with this plan, plus I have things set for example to never download unless I am on wifi). Unlimited calls & texts within the US, Canada, & Mexico, pretty good 'other' international. It depends on how you use your phone. It provides 4GLTE or 5G through the TMobile network.
