In order to downgrade to one of the current plans with 1500 minutes, they told me I would lose the T-Zones and would have to go with the current $10/month internet instead on the other lines. I told the rep I was running hacked iphones on those other lines and he said it would be fine. The money saved from dropping to 1500 minutes makes up for the extra $4/moth on the data so I have them make the switch (I also dropped T-Zones from one line that was not usinging it to make up for the increased cost).
Once they make the switch, T-Mobile cuts off data to the 3 iPhones and they keep getting a "You must upgrade" screen. I call in and they tell me I need to upgrade to a $30/month data plan for the iPhones!! I point out that if I did that I would actually end up paying more for the 1500 minute plan than I was for the 3500 and if that had been made clear I never would have made the switch.
At that point I told them to take me back to where I started and they do, but the lady gives me a big lecture on how she is doing this as a favor becasue I should not be running iPhones on T-Zones. That T-Zones is really a "phone first" plan and that the iPhone usues way more data than that plan was designed for, but she was going to let me get away with it becasue I am a "good customer" and went through all this trouble (there additonal issues unrelated to the T-Zones). This lady was in Retentions as I was so mad I was ready to eat the ETF and go, so she was alos able to downgrade me to a 2500 minute plan and keep everything else the same, which is all I wanted to do at the beginning of my week long ordeal.
So, hang onto the T-Zones if you have them and just be aware that they cut off my iPhones on the $10 plan, and this rep said I was "getting way" with running the iPhones on my restored T-Zones.
