We had and continue to have the same issue. We went through all of the same frustrations. Endless hours on the phone with tech tier 1,2, and 3. Waited precious time at the store to pick up the new SIM cards. Fast forward, five months later- still having the exact same issues. I would switch carriers but still have balances on my equipment which is the ONLY reason why I'm still with T-Mobile. I have been with T- Mobile almost 5 years and it wasn't like this before. We can barely use our T-Mobile internet when we go out- sometimes it gets so bad- we can't even use our phone gps let alone check our text messages. We have 6 lines on our account. 4/6 are iPhone 14 and the other 2 are iPhone 11. I thought I was having these problems due to two phones not being 5G compatible but that's not the case as the other phones are having the same issues. At this point we have no other choice but to put up with it until the rest of the phones balances are paid so that we can move on to another carrier. SMH
