My daughter just switched to Google Fi. She doesn’t have a phone that will automatically switch towers yet - plans to in a few weeks. She has her Moto G plus still. If she finds it good we may consider switching down the road. Curious to hear others experiences.
We just switched from a family plan on ATT to the T-Mobile 55+ plan. $70 a month for 2 lines unlimited data/phone/texts seemed like a good deal. Had some problems the first couple of days and we’re on the verge of switching back but they got the data and number porting sorted out - so far so good. We have better service at the house than we did with ATT so will probably let go of the house phone at the end of the contract (we just switched from ATT landline to Vonage).
