Re: [Services] Is AT&T really that greedy?
The 3G/2G switchover symptom is a fairly common problem in many areas, but usually it is more noticeable with data. Dropping voice calls when the phone switches modes is not as common a symptom. OTOH, simultaneous data/voice calls can only work with a 3G/WCDMA connection, so if your phone switches into 2G mode in that circumstance, one or the other connection is going to drop.
When AT&T turns off their GSM/2G/EDGE service in your area to utilize those frequency bands for LTE, your problem may be solved. In the interim you may want to investigate if your phone has a setting that allows you to force either GSM (2G) or WCDMA (3G) mode.
In my Samsung phones, I can dial *#0523# (but that would be very phone specific, and won't necessarily apply to other phone models) and I then have access to a diagnostic screen that allows me to force the phone into either GSM or WCDMA mode when I find myself in an area where I see similar symptoms.
I do know what you mean about AT&T not wanting to supply their 3G MicroCell box either free or at a discount to customers who live in problem areas. I can't use my cell phones in my home/office without a repeater because of almost no signal being available. AT&T's coverage map shows my address as being in a high signal strength area, so AT&T says that I have no problem. Rather than paying AT&T $200 for their 3G MicroCell box, I bought a zBoost repeater with an external antenna (for about the same price) with the external antenna mounted on a tall enough mast to get a good signal. That solution probably would not work for you however, since you say you have a good signal, and signal strength is probably not related to your symptoms (your problem sounds more like your phone just can not properly handle switching modes in real time).
We can never have enough of nature.
We need to witness our own limits transgressed, and some life pasturing freely where we never wander.
