- Mom's phone had a short battery life
- Dad's phone had a broken Home button
- my own phone had become unusable due to a "ghost touch" issue
But switching to the new plan was a pain in the ass. Dad chatted with an agent and placed an order, but never got information on when the phones would arrive. He contacted customer support again but got disconnected due to inactivity several times. Only after some phone calls did we find out they had not processed the order. As a consequence, the phones didn't arrive until after several days.
The good news is that setting up the phones and transferring the data turned out to be a very simple matter. I was able to start using mine right away. Although the other two could not send or receive calls, the issue went away after several hours. At least we didn't have to call customer support again.
In any case, the iPhone 13 Pro Max is awesome. One cool feature is the voicemail transcription. It's nice to be able to tell when a message is spam without having to listen to that crap. Another nice thing is that the iPhone 13 Pro Max has a much longer battery life. I can also run newer apps that don't support the iPhone 6 Plus. RuneScape on the go, anyone? :-)
