Is there any GSM choice except AT&T & T-Mobile? - General Questions and Answers

Is there any GSM/WCDMA mobile telecom carriers besides AT&T and T-Mobile?
Verizon, Sprint, Virgin Mobile, Cricket, Straight Talk... They are all CDMA/CDMA2000... But I do not want to throw away my Samsung Galaxy S phone, which worth nearly $500 and only supports GSM/WCDMA network. I really wan to get rid of AT&T, so does T-Mobile

At&t and T-Mobile HSPA+ can run same device?

I know how At&t are gonna have HSPA+ 4g, I'm confused about the new devices they're gonna have that support HSPA+. Are they going to be able to connect to HSPA+ on T-Mobile's network.
So for example, I buy an unlocked HSPA+ tablet from AT&T, straight from their store. Is it going to be able to use T-Mobile's HSPA+ network if I put a T-Mobile SIM card inside?
Also, one last question, if I use T-Mobile's SIM card, do I have to do some special stuff to get it to work on their cell network? Like how you have to unlock an iPhone for it to work on T-Mobile?
Thanks

Hello,
Unfortunately you will not be able to use HSPA+. HSPA+ is just an extension/revision of the current 3G. Effectively it is also called 3.5G/3.75G in some reports. They use the same 3G band of each respective company. The At&t tablet would work on 850/1900 band and T-mobile will work on their AWS (1700) band. So if you bought an At&t tablet, you may need to get it unlocked, not sure if they lock the sim on tablets. At best you would get Edge service with a T-mobile sim.
thanks man, argg
do you think it's worth it to change to at&t because I just heard of the Motorola Atrix and it sound PRETTY BAD ASS!
I don't know since people I know are always angry at AT&T for their service either..

NP. I have had every major carrier offered in the US. I have had at&t, t-mobile, and sprint within the last year. I had verizon a while ago and dropped them because they could never get my bill right. Honestly, the service is about the same. The question is how is the service in your area. I mainly stay in my area about 90-98% of the time. I live in a major city so all carries have great service. But I have stayed with At&t for the last few years. Every time I go to another carrier I kept my at&t service, go figure. So I would just look at coverage to where you travel the most and go with a carrier that will give you the best coverage for the best price. Do i prefer a carrier over another, yeah. I like GSM carriers better because I do like to surf and talk at the same time. Sprint can do this if your in a 4G coverage area and have a 4G phone. Verizon is a no go with this feature until they release their LTE phones. But At&t has a better coverage footprint than T-mobile that is why I stick with them. Hope it helps.
Wondering a bit about this too.
I have service through Bendbroadband using a HSPA+ SIM with USB modem Dongle by bandluxe. The service is stellar on the speed, but I can't use the dongle with everything (iPad), so looking for alternate routes before i decide to move to a different provider.
I noticed that the CTO of the company said in a comment regarding their service that any unlocked UE that supports HSPA/HSPA+ in the AWS band could be used, but also had an unclear reponse on cell phones with HSPA+.
I have a Huawei Comet (unlocked), it lists the same AWS Bands compatible, but says HSDPA (which I thought HSDPA + HSUPA = HSPA+ but at higher speeds, correct me if I am wrong), and has hotspot tether that works with tmobile web service no problem.
I plugged the SIM in, and it updates the bar with BendBroadband but I get no data. (might need to provide the IMEI or something)..
Curious if you think it should work, before i go knocking on their doors.
Some other specs:
the mytouch 4g (HSPA+) lists the bands as:850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band IV (1700/2100)
The comet is listed as: 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100)
I am fairly sure the comet is HSPA+ but not advertised that way.
According to comments on the site, Bendbroadband technicians do not actually support moving of the SIMs. Bummer.. trying to keep my business local.. Bumping and moving to Tmobile once the month is up.

please clarify using unlocked phones on tmobile

So with the refarm..can you clarify some things for me. An att phone will or won't get 4g hspa+42 on tmobile? If and when Tmobile gets LTE will an existing att 4glte phone will or won't work on tmobile future lte network?
If an att phone will get 4ghspa+42 and future tmobile 4glte
it would seem to make more sense to get an SIII unlocked att phone since it would future proof things in that it unlike a current tmobile version would eventually get 4glte?
No
I believe there are currently no att phones that get 4g on tmobile. I do think 1 or 2 tmobile phones that will work with att. Lte depend on the band of lte if it will work or not but most likely no
but if they do the refarm woudn't att bands work on tmobile?

[Q] Does T-Mobile Galaxy S3 works on Verizon network?

Hi,
I'm with Verizon Wireless and have unlimited data plan, and want to keep that unlimited data, so a friend of mine, from Puerto Rico is selling me a Galaxy s3 from T-Mobile Puerto Rico and wanted to know if I can unlock that phone and make it work in US Verizon Wireless.
Any advica will be very apreciated,
Nope, not even close. T-Mobile operates a primarily GSM network whereas Verizon's base network is CDMA. There is no compatibility whatsoever between a T-Mobile GS3 and VZW.
I thought the galaxy s3 was supposed to work on an carrier. so, not even going to verizon, getting a micro sim card and activating it?

Any GSM CDMA Wimax LTE phone?

Here is my problem...
I have 2 months in my sprint contract & need a smart phone that can use sprints wimax. I'm going to switch to at&t unlimted go phone after & would like to use the same phone to get at&t's LTE speed here in Las Vegas.
Do I have any options?
I would hate to buy a wimax phone for 2 months then buy another for for At&t LTE.
Also at&t unlimited go plan includes LTE correct??

At&t mvno question

I have at&t right now and I been thinking about switching to a prepaid plan my question is do all at&t mvno providers offer the same coverage I can't find anything online about these I would like to get at least hspa+ on a prepaid at&t carrier so to sum it all up which mvno gets hspa+ or do they all offer same coverage ?
Don't care about straightalk and net10
Any help?
Why don't you care about straight talk and net10? I would assume that all at&t mvnos have the same coverage. I get HSPA+ with mine.
I can't find straightalk and net10 at&t sim cards on their site I guess at&t pulled out I only can find tmobile sims
