MY DW and I use Straighttalk. $45.00 a month for 5GB LTE High speed unlimited talk and text. The phones we have, Samsung Galaxy S5 use Verizon towers. We travel all over Michigan , upper and lower and have excellent service. A bit spotty in the U.P, but do find areas that have service. Make sure the phone you are looking at uses either Verizon of AT&T.. Verizon is the best of the bunch! Been with them for many years, no complaints what so ever..
