I have an AT&T branded HTC Windows Phone 8X that is unlocked. I can use my T-Mobile SIM for voice, data, and text, but seem to be locked to Edge speeds. I have done a lot of reading, and it seems like it has the correct radio / frequencies to work on T-Mobile 3G, but some say it won't work. Has anyone else tried this, or have any knowledge if this will work?

Can someone explain why it I've heard that if you take an unlocked AT&T phone like the Fuze to T-Mobile or another provider, that you won't get full 3G data speeds like you do on AT&T? Isn't an unlocked phone "fully" unlocked? What would prevent data from operating at it's fullest?
Thank you! Trying to look online to find a site that will explain this and I'm not getting anywhere.
in usa it depend on what 3g band the provider use vs. what 3g band the phone have
elsewhere it would work 100% as only usa use alternative 3g bands
I unlocked my us cellular phone and now when i try to use it with ar&t i cant use the internet while im on the phone or find an at&t rom so i can use programs at&t offer can anyone help and i dont see a G next to to atenna just an E
Us cellular
So is it possible then to use the touch pro 2 from us cellular on a gsm network?
Thanks
yea it is but you wont be able to use a lot of features i believe ive been looking around for answers and asking ppl but no one seems to have anything to say
interesting. so what are the features i wont be able to use??
1) The US Cellular TP2 likely only supports the Euro 3G frequencies. As a result you will only get EDGE (indicated by the E) when on GSM in the US, not 3G.
2) If you want to use the Internet on ATT, you need to configure the ATT data settings (and of course pay for data) the same as you would with any unlocked/unbranded GSM phone. The settings can be found on the ATT site.
3) The US Cellular phone can run any WinMo programs that you install on it. You don't need a specific ROM.
To claim you "won't be able to use a lot of features" is incorrect.

I am living in Jamaica so can the us cellular touch pro 2 be used here on a Gsm network with/ without being unlocked? thanks
yes it will make call and answer but internet you need to set it up
in costa rica it works but internet does not work
wow. i have been dealing with a very similar issue.
i am using a US Cellular TP2 on AT&T, Sim unlocked and security unlocked with the radio provided by Olinex. radio version2.32.00WU. see signature.
i am using an Energy CDMA rom, and i have internet, but i have been searching for some sort of settings to get 3G. as of now i am stuck with the E, or edge data connection. i have changed all of my settings to match those of MEdia Net, but still no 3G.
Anyone have any info or suggestions?
1.) Once you have perm root and flash a custom rom you can use any SIM from any carrier correct?
I had a HTC Inspire from AT&T and running a custom rom put in a Tmobile SIM card and it worked but I had terrible reception.
2.) I also have a HTC Sensation from Tmobile that I just recently rooted and it wouldn't work with my At&t SIM. I understand this is due to the Tmobile rom on the phone and to have the at&t SIM work I'd need a custom rom or unlock the sim right?
I've read some about SuperCID but I understand that is only if you want to run another carriers rom (exp: run a european carriers standard sensation rom on a tmobile sensation) Is this correct?
3.) My main question is that since a phone's radio deals with how it interacts with wifi,gps and the carriers network wouldn't using a tmobile radio with a at&t SIM always give crappy performance and is there anything I can do about this? At&t doesn't have a radio for the sensation. Or am i looking at this all wrong?
Thank you for your help!
AT&T and T-mobile run off of different frequencies. The frequencies the phone uses does not change with the radio. When using a T-mobile phone with an AT&T SIM, you are only going to get edge (2G) speeds, and vice versa.
There is nothing to be done about this? Edge might as well be no data at all :/

Nope, nothing that can be done. There are some pentaband phones out that will get 3G/4G on both...galaxy nexus, and versions of the evo 3d and optimus 3d.

Moving to Q&A
Ok, so I've searched all over and haven't had much luck. I have no experience with cdma phones, as t mobile is all I've ever had.
I was given a new US Cellular HTC Hero s. I opened it up and saw the sim slot and though, sweet I can replace my sensation with it (I smashed the screen pretty bad). Well, that was a no go, as the phone is cdma. Looking online though, I see it can run in gsm (options global mode, cdma mode, gsm / umts mode. I unlocked the bootloader using the htc site (not sure it matters) and popped in my sim card again, and tried both global and gsm mode, though neither got signal or would dial out. (under networks, it had the tmo apn info.)
So, is the GSM mode offered on this phone only for non US bands? Would a custom rom (now or down the road) allow it to work on tmo? I read something about the HTC Merge and someone being able to switch out the modem in the rom that allowed it to work in the US, but that is well beyond me. I can follow instructions, work ADB and flash roms.. but thats about it.
Is it possible, or will it soon be, to have this phone work on GSM or am I just stuck trying to sell it as a us cellular phone (or perhaps another cdma carrier.. like I said, I don't know anything about cdma)
As a Canadian I'm not sure about who owns US cellular or if they are their own company but I'm guessing they work like Verizon world phones. They have sim card slots but will work only outside of the US. If those verizon phones are used within the States, they will only pick up Verizon's frequency, as opposed to T-Mobile or AT&T where you can unlock them and use them with any GSM carrier within the States. But yeah, you can unlock it and it will work with any GSM carrier outside the States but within the States I think it will only work under US Cellular CDMA network...please correct me if I'm wrong.
That's right, u.s. cdma "world phones" have gsm radios but are locked down from connecting to gsm networks in the u.s. This is not just the normal sim lock found on gsm phones but they are hard coded to ignore u.s. gsm networks.
Some have been unlocked to work on any network through various methods including flashing a modem from a non-us varient of the same phone and other hacks. I can't comment specifically on this phone however.

Well, that points me in the right direction, and confirms what I read about swapping modems (on the other phone mentioned).
So basically it's software telling it not use a certain frequency, and not that the phone itself is incapable of picking it up (had my doubts about that)
Pretty shady the way phone companies are allowed to operate (don't get me started on my unlimited internet in my contract [pre data caps in tmo]. "Hey! check it out, this phone uses data 5 times faster than your old one, oh, and you get half as much too) sorry, end of rant.
I'll keep searching, and post if I find something..
On a side note, can cdma phones be flashed to another cdma carrier like verizon or sprint, or is it the same deal, coded to only use a certain frequency range?
only thing I've heard of is flashing sprint and verizon phones to cricket, metro pcs and boost.
Hi,
I currently have an unlocked, out-of-contract Verizon Galaxy Nexus, and I'm considering switching to Ting, a MVNO that uses Sprint's network. However, Ting says this isn't supported, and I was hoping someone here could help me understand why.
As I understand it, both Sprint and Verizon use CDMA, so I already have the hardware I need to communicate with Sprint's network. However, the ESN on my phone is not currently whitelisted on the Sprint network, therefore it won't work.
Ting has a bring your own device program. If your phone is on their whitelist, and it is Sprint branded, you can use it with their network. So I guess what I'm struggling to understand is why Sprint branded phones will work, but non-Sprint branded phones will not.
Is the fundamental issue simply here that Sprint refuses to whitelist my ESN because it is a Verizon phone? Or is there a technical reason why I can't use my Verizon Galaxy Nexus with Sprint? Is there anything I can do get my existing phone to work with Ting?
Thanks,
John
there's pseudo-technical reason, and it boils down to the big V is a stupid way, the reason is that Verizon uses a weird (read: f***ed up) way of authenticating devices on their "CDMA" network, Verizon uses WCDMA/CDMA2000 style authentication even for the 4g towers, and the hybrid AAA/HA keys they use were developed by them for use only on their network, this is why, primarily, that sprint phones are incompatible on verizon and vis-versa (Also, anecdotaly why Verizon 4G phones are a pain to put on Verizon MVNOs though with the GNex it is possible, I have mine on page plus using Sprint's CDMA radio firmware, and YES everything, even 3G data works fine, and no, no ESN swap was needed). Basically it's a ploy to keep Verizon phones, well, on Verizon..
