[Q] Can I use a TMobile modem with an AT&T tab to get TMO 3G?

Title says it all. Got an ATT refurb but I have tzones with tmobile and would love to do better then edge. I would think that the hardware would be the same and all I need is just to use a TMO modem.
I would appreciate it if someone can tell me if this can be done.
Also, can I alter the IMEI so TMO will think that I have a different device? I currently have a Nokia that I use and I would love to "clone" it so I dont start getting charged for a tablet. I am only planning to connect the tab via 3G once in a while.

Sorry no, so many threads say only 2G+voice or 3G using rotohammers switcher
Attempting to alter imei is frowned upon.

I think that you missed my point, I am asking only about TMO 3G on ATT tab not for voice. And the devs that do this do this for fun, $1K will not get you someone for this type of a problem as I understand that this is very hard or not possible at this point with available modes out there.

Att uses different 3g frequencies than t-mobile. I don't think there is a way to change a tab's frequencies; this is an attribute of the hardware/radio.
It would be cool to do what you ask, but you can't.

3g with att from t-mobile tab

I have a t-mobile galaxy tab that I am now using on Att, I installed the newest overcome rom, have been trying different modems but so far cannot seem to be able to get 3g to work. To clarify I am using att sim card in a att 3g area. Is there a specific modem to achieve this or some settings I need to set?
My t-mobile vibrant that is unlocked, works perfectly fine with the same att sim and I get 3g, can make calls and use data simultaneously.

Have you gone through your vpn settings?

I have checked the APN settings and everything looks the same as what is set on my vibrant that is getting 3g.

I understand there ARE hardware differences between AT&T and T-Mo versions. As a result....only Edge on T-Mo network with AT&T tab....and only Edge on AT&T network with T-Mo tab.
I know...sux!

Oh, I was hoping that the hardware was just the same and the software was different on each carrier, like each one only enabled certain frequencies. Especially since the Vibrant is able to get 3g with At&t.

Big differences in the radios. They are compatible on each others voice frequencies, but they don't have the correct data frequencies.

what are your apn settings to make the att sim work and get data??

I flashed overcome v2.0.0 gold on my tmobile tab and flashed the jk3 modem for att... is that the modem I need to flash to work with at&t? I only get voice and 2G only. Someone said maybe I need to flash jpz modem? would that get 3g data on my tmobile tab with at&t sim?

I give up. What's the point of posting accurate information if people won't read it?

Standing right beside you Captain.

I feel sad Cap, the crush on galaxy tab made me buy a Tmo TAB and I am a ATT user. I just want to sell my current one and get a ATT to enable 3G data...damn...

I have two tabs: the t-mobile tab I first bought, and the at&t tab I bought after I learned.

[Q] factory reset

hey guys quick question
i brought a at&t nexus1 off ebay. the seller mentioned it will can and only work on tmobile 2g [i am t-mobile],
my question is if i factory reset/wipe the nexus1, does it lose complete compability with tmobile?

Factory reset only wipe data. you can still use the phone with tmobile
and still 2g only

so flashing roms, kernels, recoveries and all that good stuff, in the end i will still be able to activate the phone aka [ google sign in at the beginning activation ] with a tmobile sim card?

Yes. Just keep in mind that you'll need to stick with american firmware. With different ROM, you can even use 3g, but it depends on you provider too.

He will not be able to use 3G on Tmobile no matter what ROM he use.
The 3G limitation is a hardware issue.

Really? How so? Nexus One do support 3g. Isn't it matter of installed modem? But maybe T-Mobile has modified it somehow on hw basis...

There is two version of Nexus 1, one made for Tmobile frequency and one made for AT&T. While they are both sim unlock, you can put sim card from either carrier into the other and it will work as far as phone calls. For 3G support a Tmobile sim in a AT&T N1 will only work with 2G not 3G.

I suppose that it is only T-Mobile's fault, not phone's. Phone itself do support 3g, and I do suppose that T-Mobile has just disabled 3g on the SIM or on the modem's side.

How is it T-mobile's fault? Their 3G work on a certain frequency. AT&T 3G work on a certain frequency. If you buy a phone that does not work on your carrier's frequency, it's the buyer's fault*.
*Nothing against the OP in this post. He knew he bought a AT&T N1 and know 3G don't work on T-mobile.

yeah lol i dont even have data on my phone, so 2G / 3G doesnt even matter to me,
im just worried if it i factory/hard reset the phone, that the phone will "lock" back on AT&T.
but imo, since the N1 is carrier unlocked by nature, it will stay that way no matter what i do right?

correct, factory reset will only wipe data. out will not get lock into any network.

True. So then we are back at my first point - wrong modem. It can be easily reflashed without loosing any data, so Nexus will operate on frq your provider uses.

You cannot change the operating frequency of the phone - it's a hardware limitation.

Maybe if you flash a new modem it can run on Verizon.

It'll be good if you actually read before making false statements and insisting on them.
Read the FAQ, question 13.
Nexus has 2 HW variants, with 2 different sets of 3 frequencies for each variant. The variants differ in HW and use exactly the same SW, including modem.

Verizon XT862 on Manitoba, Canada's MTS Network!?

Hey everyone.. I've been combing through forums for the past 5 hours trying to help out a buddy. He picked up an unlocked Verizon XT862 a while back, but we're having a heck of a time getting it on Manitoba's MTS network (partnered with Rogers in Manitoba, Canada). I put on .890, then rooted, safestraped, and tried Steel Droid. It won't find the MTS gsm network. I even have tried screwing around with a 883 radio and modified build.prop. It would be great if I could just run the Bell XT860 firmware as that would probably do it, but I have heard that's impossible. So has Verizon just locked the ever locking crap out of this things GSM or what? Any way I can get voice/sms/data working up here on this thing? I desperately need some help. Thanks!

i dont think verizon locked anything.... Im using a GSM simcard in Lithuania without any problems, try switching your phone Network Mode to Global or GSM/UMTS

Hm.. Okay thanks. I'm just reloading the SBF to get it back to stock. It will find Rogers, but I can never get it to see MTS for some reason. I will keep trying.

So I reloaded the SBF and same issues. When this phone is on Network Mode: GSM/UMTS , it finds Rogers 3G and 2G. If I pick Rogers 3G, I don't get any service. It just has the red No over the signal bars. If I switch it to Network Mode: Global, it gets almost full signal strength, but in *#*#4636#*#* its using the CDMA network. If I change the preferred network type to GSM only, it never finds anything (assuming its only looking for Verizon?). If I try GSM auto (PRL), then it doesn't find anything either. I just don't get why its not finding our MTS 3G network in Network Mode: GSM/UMTS.

Yeah I have the apns from MTS already. It still doesn't seem to find MTS though. Only Rogers comes up after network scans. I'm going to try to modify the build.prop.

Does it use the Rogers network, or have its own? What spectrum does it use? Are you sure the d3 supports its spectrum? I didn't see that info in my good search, although I did see they have a legacy cdma network, can you find that?
Sent from my XT860 using xda premium

Endoroid: Thanks for the help. Yeah they used to be purely CDMA (EVDO and 1x), but they decided to partner with Rogers in Manitoba and share the HSPA+ (21Mbps) towers. As taken from their website: Please note that any unlocked device must support 4G North American Frequencies (850Mhz), older GSM devices will not function on our new 4G network. You can find out if your device is 4G compliant by reviewing the phone's settings.
So it looks like they operate on the 850Mhz spectrum, which should be fine for the quad band XT862. I'm not 100% sure if the network search should show up MTS 3G or not. I don't have an official MTS GSM phone to check it with. It does find the following two networls:
CAN Rogers Wireless Inc. 3G (302-720)
CAN Rogers Wireless Inc. 2G (302-720)
I would assume I should see something like: CAN MTS Wireless Inc. 3G (something here), but nothing ever shows up. If I select either of the Roger's networks, nothing ever happens. It just has the red block over the signal bars and it never grabs a signal. Then I randomly get the following popup:
Network Error
No GSM/UMTS networks were found. Would you like to switch to the Global mode?
I've had it pull the 1x legacy MTS CDMA network before. I think that might have been in Global mode.
So confused.

Okay I'm RSD'ing VRZ_XT862_5.5.1_84_D3G-55_1FF_01.xml back onto this thing. That should get me back to stock, right? I don't know why it doesn't just work with the stock setup. I really should, shouldn't it? It's unlocked, just load the apns and go? Weird. Does RSD'ing that file reset the radios and everything? I'm not sure what all has been messed with on this thing. I'd like it back to virgin if possible.
Edit: So I reload that file and it boots up asking about international roaming. I agree and it pulls a network. It's MTS 1x CDMA though. I put it to GSM/UMTS and do a network search and the two Rogers networks show up again. If I pick one of them, I instantly get a notification bar error about no service and selected network unable... I have an MTS SIM in this thing and the mts apn entered. So weird.
My buddy said at one point while he was messing with it, he had it find the MTS gsm network. He can't remember what rom or what he had done, but he still couldn't get data working. Only voice/sms. Should I try a different rom? Any suggestions?

I dont think rom will matter. You could try editing the build.prop. Change default network mode from 7 to 3 and verizon global phone from 1 to 0. These are the changes needed to get d3(cdma)roms to work on my xt860(GSM) .
You could add the apns to /system/etc/apns-conf.xml I don't think that will make any difference as it should read it from the sim, but never hurts to try.

That's exactly what I've been trying in regards to the build.prop. Doesn't seem like it ends up doing anything thouhg. Not sure. I will definitely try adding the apns to that other file though. Thanks again!

Ya im sort of at a loss. I've only ever used my device on the bell network(the carrier I bought it from) so I've never had to deal with this issue. Hopefully someone with more experience in this will pipe up

For some reason I recall reading about XT862 users having to flash something like the XT883 radio to access GSM networks? Or am I mixed up...

Hey guys.. I had sifted through most of that thread and attempted the radio and build.prop flash, but I was still having troubles. Maybe I'll give it another go. Thanks!

I'm trying to follow this post: http://forum.xda-developers.com/showpost.php?p=24176930&postcount=176 because I've never put .906 on this thing. I can get the chinese ota to install with rsd fine, but I'm having troubles getting the XT883 OTA.zip to flash. It errors out while installing with safe mode on. Should I be running a different recovery? Also, whenever I try to launch recovery from startup, it just triangle ! errors and dies. Something must be missing. Should I have CMW recovery on this thing instead or any ideas?

I'm having the exact same problem.
I have an unlocked DROID 3, which is working perfectly fine for voice and SMS, but no Data.
I've tried flashing the XT883 radio img, which did nothing.
I'm thinking I might just flash the whole XT883 ROM onto it, maybe it'll make a difference?
But, in regards to your case, I do recall that someone mentioned not being able to get a data connection in Canada, en they had to play around with the libmoto_ril.so file.
Here's the thread:

Flashed XT883 ROM. No luck.
Only change is that it's automatically getting the default APN's for the network. But no DATA.
At this point, Could it be a hardware issue? My voice and sms radio is working perfectly, are they linked? WIFI works fine.

Does I9000M (Bell) works with Mobilicity?

Does I9000M (Bell) works with Mobilicity? I have a Bell Note which works with Mobilicity. My Galaxy S is sitting around dark. I really want to use my Galaxy S sometimes Just for a change. Is there any Modem which I can flash to make it work with Galaxy s?
Thanks

Short answer is no.
Mobilicity and Bell don't use the same frequency band.
Tried my brother's sim card and it didn't work.

i also would say no due to differency but maybe other hav some 'shortcut' method that wouldnt brick ur fone by changing modem

Thank you Guys. I just thought that it is possible to flash a different modem because I am using a different modem on my note and works with Mobilicity. I remember there was a thread where people were trying to get it work with AWS bands. I guess, No Success yet.
