We've been on the T Mobile "55 plus" plan for about 6 years now. We're very happy with the service, we do experience weak spots from time to time but for the most part it's worked good for us! 55 plus with T Mobile costs us $70/mo all in, NO extra fees. 50 gigs of data each phone, unlimited texts and unlimited talk. I now have a 5G capable phone and their 5G service is available in LOTS of areas. Love it! :B
On a side note, we just got T Mobile's 5G Home Internet gateway a week ago. Where we are right now (NO WIFI supplied) we had to do something or "burn up" your data on our phones. We decided to try the Home Internet, so far the gateway is working GREAT! :C
