Since I am not an experienced arranger player, I can't contribute much but I benefit from this forum and I wanted to contribute in a different way.

We've been with AT&T more than 10 years. Currently paying $220 and more for 4 lines. The monthly bill reflects a 28% corporate discount. So it could have been worse. I did some homework and made up my mind to switch to T-Mobile. If you don't need a new phone, the best route seems to be pay off the early termination fee yourself and bring your device to T-Mobile. With us, three lines are still under the AT&T contract. Even after we pay the early termination fees of $600 ourselves (actually you are paying for the phones), we will be saving $600 a year and $1,200 from the following year on while taking advantage of more features from T-Mobile. Besides T-Mobile, there is Google Fi That might work better for others. I should have shopped around sooner. It is amazing to see a lot of young people paying $1,000 for a phone.
