We celebrated the new year by ditching Cingular and getting those awful Blackberry 7105t phones with unlimited voice/data/text.
I'm still grandfathered into that plan, which isn;t always the cheapest, but it is NEVER data capped for me, NEVER limited in any way for video playback, NEVER limited for streaming of any sort.I have never had an overage in now 11 years and 3 months, ever.
Now the complaints...
At my previous office location, the cafeteria suffered from being located too close to an old GPRS tower that TMO leased, and I had to sit by the windows to get 3G service. They could not solve it, the leased tower solved voice problems and the owner was raking in $ without further effort.
Moved to my current office location 3 years ago, and here the lunch time demand is so great that I usually cannot get data service. Fortunately I like the lunch spots that give me WiFi. My Blu R1 HD may not be getting Band 12, but I don;t care to diagnose it further until my new phone next month. TMO will not build out further here, so it may be solved with Band 12/66 (TMO is leaving some Band 12 sites for Band 66, which is wack), though spectrum is changing for TMO so fast they can't keep up with phones, SDR can't come soon enough.
My vacation spot was without service for 10 years until TMO finally got Band 12 there, which they bailed on for Band 66 this past fall. At least the resort WiFi got fixed.
TMO does have odd dead spots, but not as many as Sprint. Mostly long stretches of highway through 'wilderness'.
But on the positive side:
Great customer service. Even when they can't solve the problem, they are at least pleasant and honest.
They follow through when they say they will. I've logged several 3rd level calls, and got engineers calling back explaining. Once even a roaming problem turned out to be a config problem with my phone, and they helped me set it right.
I have no intention of changing service, though right now I'm paying a bit more than I like with a 3rd line and extra phone on EIP. But it's too close to what VZW would gouge me for, and no one else can match it without exposing me to random plan changes.
