No strictly analog AMPS accounts have been activated by any carrier for years. Mark Cuccia was using an AMPS phone up until several months ago and only changed because they were not making the batteries he was using in his Moto handset and Cingular wil not activate any analog only and now will not activate any TDMA (IS-136) handsets.
You'd think a reputable company would do just such a thing. Unfortunately that's not Cingular's attitude. Former AT&T Wireless subscribers saw this first hand. Initially Cingular would tell AT&T Wireless subscribers if they wished to get a new phone for their AT&T Wireless GSM handsets TS. You'll have to convert your account from "blue" to orange meaning Cingular pay *$18* and force you to buy a new handset since Cingular would not provide unlock codes for AT&T Wireless handsets so they could be used on the Cingular network. Cingular's attitude seems to be that "customers are expendable" and that they don't mind if they lose customers because they got the shaft from Cingular. In other words "we are Cingular, you will be assimilated."
Of *course* they would say that! They wouldn't dare admit that the network was deficient!
In built up areas usually it's pretty good. In rural areas it's a mixed bag and often not as good as what was available with analog AMPS even though they might claim differently.
Analog often works better in rural situations than do the digital technologies. As far as the technology analog is really over twenty-three years old since the first analog AMPS systems were put into commercial use in 1983.
No. There is no "A/B" switch as there was on analog AMPS. With GSM the way it usually works at least on monthly billed accounts is your home carrier (such as T-Mobile, cingular, Suncom, etc.) will be what you will generally use. *If* your home carrier has a roaming agreement with another carrier you can use that service if it is available and a roaming agreement is in place. If no roaming agreement is in place all you'll be able to do is call emergency911/112 (if there's any GSM signal at all available.)
A & B were only used in analog AMPS never in digital technologies.
Actually the way I understand it is that the carriers are mandated to keep the analog AMPS system running through February of 2008. After that date the FCC has given permission that the analog system *may* be shut down. There is no mandate that the companies running analog AMPS shut those systems down, but you can most likely be assured that they will so it will free up that part of the spectrum that analog AMPS uses so they can better use it for GSM or CDMA voice or data service. Spectrum is very inefficiently used with AMPS and is used more efficiently with TDMA/IS-136 but is nowhere as efficient as GSM or CDMA technologies.
The carriers will shut down analog systems as soon as they can. TDMA/IS-136 also uses spectrum that GSM could use if TDMA/IS-136 wasn't using it so it's in cingular or any company running TDMA/IS-136 to get customers off it as expeditiously as possible. cingular chose to do it in as unfriendly a manner as possible is the difference. cingular could have offered incentives such as free handsets or allowing former TDMA/IS-136 plans to be transferred to GSM. That's why many people were keeping the older technology since they had really good plans and cingular doesn't have anything that's close to the benefits they get with their present plan so they have stuck it out and decided not to go with a GSM plan because of the perceived benefit they have with an older plan on 1st generation TDMA/IS-136 technology.
