I figured I'd ask here. I'm almost certain that it isn't possible at all to do but you never know what the great devs here at XDA has come up with.
I have a HTC HD7s from ATT. It's a GREAT phone in my opinion. Never had a single problem with it; but I did with AT&T. They were just; lacking in terms of anything in my local area.
Now for my question; It's probably not possible but like I said you never know until you ask. I am currently running on Sprint service with my Epic 4G Touch. Love the service as it does what I need it to do (a lot better then AT&T ever did). Now AT&T is GSM if I'm correct and I know sprint is CDMA.
But what could I change my HD7s over to via flashing/custom roms or whatnot. I doubt sprint would even think of being an option; but if there's a way to get it on even a pre-pay service; I'd love to have it sitting around as a backup phone if I ever needed it. So is it possible to flash over my HD7s to any other carriers? I have read that my current phone can actually be flashed to multiple other carriers, but with sprints (decent) service, there's no need.
Thanks ahead of time!
Your HD7S cannot work on a CDMA network (Sprint, Verizon) because it lacks the necessary radio hardware. No amount of flashing can fix that.
If it's unlocked, you can use it on any GSM network, however; no flashing would be required for that. The most obvious example of a non-AT&T GSM network in the USA is T-Mobile. Your phone will work on T-Mobile but won't get 3G due to lack of AWS UMTS support -- in other words, it doesn't have support for T-Mobile's 3G frequency.
If you can find a virtual network operator that uses AT&T's network, then you should be able to use your phone on that network and get 3G. I'm not up on which operators that might include.
The specific thing you need for your phone is a "SIM-unlock" which means removing the restriction that AT&T puts on their phones to prevent using SIM cards from other carriers. Typically, AT&T will remove this lock for you if you ask them, but otherwise there are sites online that can sell you unlock codes or you could try calling HTC.

I understand (I think) that T-Mobile uses different bands for its 3G than AT&T. So, my unlocked TP2 doesn't do 3G on AT&T's network.
My question is, can that be changed with a ROM? Are those frequencies embedded in software are hardware? I really like this phone and I'd rather keep using it than sell it and get an AT&T version when it's available (with the AT&T keyboard).
Thanks,
Shane
Unfortunately, can not be changed. It's radio hardware and of course sorftware support. You will need to get a ppc for the at&t for 3g bands...
One of the mods (GSleon3) has said that he can get 3G on his unlocked Fuze on t-mobile in the Raph rom forum, but it only works for a while, and if he soft resets the phone, it basically freezes and then he needs to do a hard reset. It can be done, but not well, I guess. I guess you're trying to go the other way. You may want to look up the thread, there does appear to be some hope (but very little, lol).
I have a sim & security unlocked Sprint phone touch pro 2 that we use on the AT&T network, USA. It works well, and registers with AT&T, but then after a bit it gets dropped, and pops up asking if you want to register with the network again. My friend has the same thing, and we are using different ROMs, and have tried different radios, but we both have this same issue. Does anyone have any idea how to resolve this issue, maybe a registry edit or something?
thanks.
I'm also curious about this. I'm on Verizon and was given the phone to keep from my last employer and my new one uses AT&T. I haven't done enough digging yet but wanted to *bump* this thread as I'm looking to keep my CDMA VZN phone and use it on AT&T permanently and wanted to know if there are others who have done this already.
*Anyone had success with using their CDMA phone with AT&T/Tmobile without GSM disconnecting as the OP mentions?

wooties, I read somewhere where the verizon touch pro2 works for AT&T GSM in the us, but not sure where. Search xda and ppcgeeks. I have the Sprint touch pro 2.
I just answered this one in another thread, so here is a copy and paste...
With your AT&T SIM in you probably need to set to manual network instead of automatic so it stays connected to AT&T and doesn't try to flip back to CDMA - if you've already one this, then someone else will have to jump in, but the settings are:
All Settings > Personal > Phone > Network (tab) > Mode of Operation = GSM/UMTS Only
This should keep it from jumping back to Sprint and then back to AT&T where it asks you to register again...
Remember though, with a CDMA world phone, you will only get 2G coverage here with your data as the 3G radio is a different frequency.
Hopefully that does the trick - and if not, someone else jump in and save them quick!
After much searching I found lots of 'no you can't's, but I haven't found any posts that are recent, ...in the last 6 months.
I have a Sprint Touch Pro 2 that I successfully got working on Page Plus. I would like to get it on my folks' Verizon family plan. I called an agent and they said if it doesn't have a Verizon logo on it, it's not possible.
I question this, but I've found no one of late posting about this.
I think the phone will work on Verizon, it may just need the ESN number activated on their network.
I remember someone here or at PPCGeeks activated it for me on PagePlus, is there anyone/any way to activate it on Verizon?
I like the phone, I just don't need data, so I don't want a regular Verizon phone.
thanks,
Yes, you can get it activated on VZW... The only problem is this... you can't do it legally or ethically... It would involve doing things against VZW's rules as well as the law... and you would need a "broken" TP2 (or other VZW phone) to do it... But that aside... the reason it worked with PagePlus is because they allow outside phones on their network, with giving you the responsibility to make it work on their network.. VZW is vey explicit that they will NOT allow anyone elses phones on their network (same with Sprint)... They are the worse 2 when it comes to that IMO..... Sorry to the bad news.... But sometimes that is how it goes.... Maybe you can post an ad on here offering to trade someone yours for the VZW version.. or maybe Craigslist?
Thanks,
Trading for a verizon phone won't work, as then I'll have to get data.
My bottom line question:
I need a smart phone, but I NEVER need data, wifi is always available for me. But I guess there is no way to have an Android phone on a Verizon network, without a data plan?
Not legally anyways, that's one of the downsides to using CDMA, the carrier has much greater control over what kind of phone you use. Thankfully they can't control the Rom/OS you run on it .
You need a Verizon rep that knows what they're doing, it can be done.

Hello,
New here, don't see an up to date thread on this issue. I moved and Verizon has no towers here, so I had to cancel. I'm lucky to get a single bar of 1x or maybe 3G. Then it cuts off. Anyway, AT&T is about the only choice here, tower coverage wise, so I was looking into it. I popped in an old SIM card from a friend's AT&T phone, and it recognized it, didn't seem to request an unlock code. My contract has been up with V for months, not sure if that has anything to do with it.
Poking around, seems like basically the issue is some providers use GSM towers (like the rest of the world's standard) but a few like V use CDMA. This info seems a little outdated, probably because not a lot of folks care about the older Razrs anymore. AT&T seems to have upgraded a lot of their service to LTE now. I might pop into AT&T tomorrow to see what I can come up with. My GF has a family plan thingy going so to add this old XT912 would only be another $20 / m.
I just thought I'd throw it out there, and ask you guys what sort of problems I'm going to have? I've read I might get signal, but no data. I've read that the physical radio operates on a different frequency and might connect to GSM but might not be stable. Just wanted to hear your thoughts in laymans terms. I'm pretty new to phone modding, but it's interesting for sure.
Thanks for any attention.
Just looked up more about the physical issues with phone radios. Stumbled across this app named GetRIL
Read on other sites that some phones are Radio Interface Layer locked, which I think is just the physical limitation of the phone. After the FCC changed some things, like forcing carriers to unlock phones after service is complete, most newer users won't have this issue. Anyway, it's interesting reading.
I'm trying to find out if what I would like to do is possible and if it is, how I would go about doing it. I've already spent hours scrolling threads on here looking for information. I feel like I've scratched the surface but I haven't found exactly what I'm looking for yet to confirm whether or not I can accomplish what I'm attempting to do.
Let me start at the beginning. I own a Samsung Galaxy S5 LTE-A (SM-G906K) and I recently switched carriers from AT&T to Verizon. At the store I was unable to get the sim card to work with my device. I also checked the IMEI on Verizons website and it said my device was not compatible with their network. Out of necessity I picked up another phone. I know Verizon is or has been a CDMA network but from what I understand, they are transitioning or have transitioned to a GSM network. The phone I purchased at the Verizon store; a G360V; does not work without a sim card, which seems in line with any other GSM device. Furthermore, I tinkered with service mode on my G906 to get a LTE connection a while back and I saw a CDMA option in the menu. Out of curiosity, I checked out service mode again. Sure enough through navigating the main menu in service mode I can access numerous options containing "CDMA" in the title. The problem is I don't know what any of these options do.
I would like to know if there is any possible way to get my g906 working on Verizon's network. I feel like this would be more or less easy to do with an American device but since I have the Korean version, the model I own was skipped when non-Verizon devices were certified to be on the network. I assume this because apparently quite a few individuals have brought their own device on to their Verizon plan.
So my questions are: Where should I look to get more information about getting my Verizon sim to work on my g906? I see a lot of info about switching from Verizon to a different carrier but what about the other way around? Where can I get detailed explanations of the service menu options and their functions?
Thanks in advance
Hi, thank you for using XDA Assist. The best place to ask is in your device's specific forum here, http://forum.xda-developers.com/galaxy-s5 Also see this, http://forum.xda-developers.com/galaxy-s5/general/sm-g906s-k-l-owner-thread-t2807639 This is probably the best place to start.
