3g with att from t-mobile tab - Galaxy Tab Q&A, Help & Troubleshooting

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?
Sent from my HTC HD2 using XDA Premium App

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.

Bell Galaxy S Vibrant

I live in the USA, using AT&T, and is shopping around for Galaxy S phone. The Captivate is the obvious choice under the Galaxy S flag. I just noticed the Galaxy S Vibrant from Canada today and I am really interested in it, especially because of the front facing camera.
How would I go about purchasing it? How would I get it working under the AT&T carrier? How is Edge, 3G, and voice, etc? How would future rom updates be installed? What are the down sides to buying the Vibrant versus a local Captivate?
Thanks
I have a Bell GS and on Bell it works great. Though after a firmware upgrade yesterday is is acting a bit wonky, might have to do reset.
To use it on ATT in the US you would have to buy it outright from Bell or other brick and mortar store that carry Bell phones. ie. Best Buy/FutureShop.
There is an unlock app for GS's and supposedly works on the Bell I9000, haven't tried it myself, no need atm. This will allow you to use a ATT sim card in the phone.
To update, you can use Samsung kies, supposedly what they will be using to push updates to GS, you can get that from samsungs web site. From what I have found so far you need to be in the touch wiz launcher to use kies. only matters if you use 3rd party launchers.
Not sure how the FFC will work for you. That might be dependant on ATT?
Your best bet, if you decide to get one. ROOT and make it your *****!
It would be 100% compatible on AT&T's network. In fact, it's even more compatible because Bell doesn't have a 2G network you can switch to to save battery life.
ROM updates come officially through Kies like normal, although you should also be able to flash most international i9000 ROMs you see floating around here, just make sure before doing so. Flashing a Captivate ROM just because you're on AT&T is a surefire way to brick your phone.
To buy it you will likely need to use something like eBay because even if you purchase it outright almost every store won't let you leave unless you have existing service with Bell. You can unlock it for free though with the method that I am sure is detailed on the Android Development board somewhere.
The obvious downside to buying Bell's Galaxy S is it comes at full retail price (over $500 Canadian) and in all likelihood you're probably going to get a model with the three button download/recovery modes disabled, making flashing ROMs risky. Hold out until the end of this month to see if Samsung Canada announces more about their promised fix for this.
I am using one on AT&T as well and it works fine. Best part is that AT&T doesn't force you on their limited smartphone plans and you can put it on a cheaper unlimited plan.
I got mine in a trade for a BB Torch but you can find one on eBay or maybe talk to a Canadian member here to see about picking one up for you. I would suggest you have them check for the 3 button recovery to make sure it's working before they buy it though.
The downside is warranty issues if it breaks but as long as the 3 button recovery works you should be able to recover from a bad flash and the hardware seems pretty solid so far so no worries there.
Based on the responses, I am definitely going with the Bell/Canadian Vibrant. The only trouble I have now is just finding one to purchase.
How do I post my intentions here to let people that I want one? Who is a reliable dealer here?
Many Thanks
GH
the bell ones got both 850 and 1900 bands?
Also does it have a bell logo on it or is it unbranded.
send me a PM if you want to buy a Bell SGS with 3 button working tested, and GPS tested before mailing it to your address of choice.

Epic 4G (used as 3G on Bell / Rogers)
Hello,
I am interested exactly the opposite: I want to buy an Epic from Sprint (with no contract) and to use it in Canada (on Bell or Rogers) but only with a data plan, no voice (as I will use the SIP / VOIP). If Bell or Rogers offers only data plan, should this phone (Epic) works out of the box (or with the unlocking code) on the 3G network of Bell / Rogers, simply inserting their SIM card into the phone?

the sprint version is CDMA, chances are it's CDMA locked to sprint
CDMA unlocking is done on the server side, is not on the phone like GSM
you need to register your CDMA IMEI number to the say... Bell or Telus, if they see it on their server it's allowed they will let you in, if they see it listed as not allowed then they wont register the phone into their (Telus/Bell) CDMA network

Thanks for your answer.
I am not a tech, but the 4G/3G is also depending on CDMA? Or CDMA concerns only voice? Is it 4G/3G a standard (the same on Sprint and Bell and Rogers) that doesn't depend neither on CDMA or GSM?
we don't have 4G support yet in Canada
CDMA is for voice, but if you can not register the phone in the network for voice, you will also not get access to data
to have data you must have a voice connection
not a phone requirement but a phone network carrier requirement
Thanks.
Anyway, I checked right now with Bell and Rogers and no one offers only data plan... But what they will do with iPad and Galaxy Tab that doesn't support voice, but only data? If I will take the SIM out the gTab and put in a phone (Epic or Vibrant or Captivate), will the phone be able to work on 3G?

Yes, but if Bell already sells the dataonly plan for iPad, why they don't sell a dataonly plan also for a smartphone?
because they can claim a Tab is "not a phone" (whatever...)
and a Galaxy is a "phone"

I currently have a I9000 and am on ATT's network in southern california. I'm all but satisfied since my coverage is poor indoors and in some areas because of the lack of 850 band support.
I'm looking to move instead to the I9000M from Bell to get the added 850 3g coverage. Were you able to get a phone, root, unlock it and upgrade to froyo 2.2? Can you tell me about your experience so far including testing for 3-button boot into recovery? Where and how much you got the phone for out-the-door? Thanks.
Sorry mate, still waiting on mine, can't believe its been a month. An xda member here indicated that the stores in Canada are out of stock for awhile now.

[Q] Nexus 1 stuck on Edge signal

I just purchased a rooted Nexus 1 from eBay. It came with Cyanogen 6.0 RC3. 5.08 radio. I noticed it was always displaying an E for edge signal. I went into the phone menu (*#*#4636#*#*) to set it to WCDMA Only. It then would not get a signal at all. I set signal back (WCDMA perfered) and Flashed Cyanogen ROM again with 4.06 Radio. I still get only EDGE. I have another Nexus 1 and it goes between H and 3G (HSPA is active in my area). Does anyone have any idea what could be causing this or how to fix?
One is AT&T band and another is T-Mobile band, perhaps?
No they r for T-Mobile. The problem is it only shows edge and never 3g like it should.
Sent from my Nexus One using XDA App
Try flashing back to stock to see if it keeps doing that.
Did you check settings>wireless & networks>mobile networks "use only 2g networks" unchecked. I assume you did since you know the (*#*#4636#*#*) method, but maybe someone else will read this who needs it. If that doesn't work I would test an ATT sim card to clear my curiosity.

Yes I did check this. What will testing phone with ATT sim card do? Phone is advertised as unlocked and rooted. What am I missing?
For 3g, T-Mobile USA exclusively uses the AWS 1700/2100 MHz frequency-band, and ATT uses the 850/2100 MHz band, so a special batch of N1's were made for ATT with different hardware. If a friend's ATT sim card picks up a 3G signal, it means you can't pick up T-mobile usa.
You said the phone was advertised as unlocked and rooted. The thing to check would be to ask if the phone is compatible with ATT's 3G bands or T-mobile's 3g bands. "Unlocked for all GMS carriers" for example, only tells you that it works on all EDGE networks. I haven't seen a Nexus One that can run both 3G networks, but they may exist. (Was there anything in the ad specifically about the 3g bands?)
The ATT Nexus One is more rare, you may be able to sell or trade with someone in the marketplace here on xda or on the internet somewhere.
Sanity check: shut down the phone, take off your battery cover, remove the battery and tell us the FCC ID. It's in the second of three lines of text below where the barcodes are.
My AWS (T-Mobile) Nexus One says:
FCC ID: NM8PB99100
If you have the AT&T version it should say:
FCC ID: NM8PB99110
Note the single-digit difference. If you have the AT&T version you'll want to trade it with someone else who has the T-Mobile version in order to get 3G. If this is the case, you're in luck, because the AT&T version is discontinued and lots of people would be very happy to obtain one from you.

Thanks for the information. You hit the nail on the head! The phone is marked as one of the early AT&T Unlocked models. I also had one of my friends put his AT&T card in the phone and it picked up 3g just fine. I spoke to seller of this phone on ebay and he said he would take item back. IS THERE ANY WAY TO FIX THIS PROBLEM SO THAT PHONE WILL WORK ON T-MOBILE?

hmm...I don't think so.
Take it back to the seller or trade with someone
As many already stated in the thread (starting with me), you have AT&T Nexus, and there is NO WAY to make it work with T-Mobile. But, as also stated, you're lucky - lot of people will probably be happy to trade with you or buy it from you.
I just got a flawless AT&T Nexus One for next to nada $150 from a guy that heads up the IT department at a hospital, he had bought over a dozen f them and I mistakenly thought that since they were Google Nexus devices and since I had a "android data plan" and because I could make and receive calls and get on the web that all was good! What I didn't realize is that I'd be stuck on EDGE for good, they only real downside is that I cannot be on a call and surf the web at the same time, I'm just glad I got a pristine phone that's outta warranty, and running 2.3.6 (stock) and for only $150! Also I've always been a physical keyboard guy, so darn I get EDGE... I run the fastest web on my WEP encrypted network at home and hop on the VPN network at school, and now that the bastards at TMOB don't offer (unlimited) I really don't use alot of data anyways cause I don't goto social networking sites neways!
Any one wanting to trade a TMOB NEXUS ONE for a ATT NEXUS ONE??

[Q] Captivate on Wind Mobile? (Voice Only)

Is it possible to use the captivate (2010 year models) on Wind Mobile in Canada? I have a rooted and unlocked phone, but when I put a Wind Mobile SIM in the phone, it did not seem to show any service of any kind.
I do understand the phone is not capable of AWS, and I don't really care id I can get any data anyway, just voice would be great since I have wifi availble most of the times when I need it anyway.
I am willing to load whatever ROMs, modems, etc to get it working if its even possible.
Thanks!
No sorry, that's not possible. Try the T-Mobile version, unless you'd like to be roaming on Rogers all the time
you need APN settings for wind.call them and get them
So a rogers captivate will work on wind?
With the right APN settings I dont see why not.
False, it doesn't have the right frequencies to get reception.

Just to confirm, I can't even use my captivate on Wind even for voice only calling. Just want to make sure since this APN talk I figured was for data which I know won't work since its 1700/2100 AWS.
I only want to use Wind since there voice plans are so cheap, but I can not afford another phone at the moment.

[Q]S4 Active on T-Mobile Network, need help getting Data.

Hey there, I just got an S4 Active hooked up with T-Mobile's $30 plan. There's really sparse information on the S4 Active, and even less for people who are using T-Mobile on the S4 Active.
My problem is I'm only getting EDGE. I've searched the forums and found a couple of people who say they plugged in their SIM and it worked flawlessly. Is there anything I need to do? Open up AWS? I've tried using default APN, calling T-Mobile and having them give me the information, and using APNs I've found online, but I still get EDGE.
It'd would be a shame to have such a nice phone and only be able to use EDGE.
Edit: I've also tried enabling AWS using this guide [http://forum.xda-developers.com/showthread.php?t=2291589], first it says "USSD Code running", then I get an error saying "Connection problem or invalid MMI code."

Raydi07 is better than geohot
here's how you get 4g LTE to work.
google search: "How to Enable T-Mobile HSPA+ AWS Bands on AT&T Galaxy S4"
the part where it says: Step 2. Dial “*#7284#” on your dialer. Use *#0808# instead
follow everything else by the book.
you'd think "durr this method only flashes hspa+ bands durr" no. I get 4G LTE on my at&t s4 active. sometimes it just says 4G tho when im out in the boonies like where the other useless people are

Thank you so much! *#0808# Worked perfectly. I followed the guide closely, and I now get 4G. Could I ask what you have your *#2263# set on and your *#*#4636#*#* data preference?
yeah boy
I got my 2263 set to lte/wcdma dunno about the other thing but I never been dropped to 2g or 3g always stayed on 4g with the occasional 4g lte! I don't want automatic cuz maybe it'll save some battery so it doesn't scan for signal all day. If rather 4g or not have any data at all

4G LTE or possibly HSPA+ will not work on your international version S4 Active I would recommend to go to AT&T Store and buy full paid or eBay or swappa.com have some AT&T S4 Active unlocked that will work on AT&T and T-Mobile LTE
Also i m not sure if you need s4 active then s4 because not that much of protraction and you are giving up on better screen and Camera MP
If it was up to me I would stay with regular s4 but that's just my own opinion

so im still new at doing things like this and i attempted to figure out how to do this but wasn't able to wich is no big deal but now when i conect my phone to my pc the storage doesn't show up not sure if this is what caused it or not but if anyone could help that would be great btw sorry if im posting this in the wrong place im also new to xda
SGS4 Active No HPFS
I have followed every step, but I still haven't seen the changes. I get no errors, the QPST programs says completed and my phone reboots. I've done this several times and still no change.

Upon reading the "[GUIDE] Using I537 on T-Mobile and other AWS Networks", I successfully got one phone to work, however I have been trying for a week, almost 2 weeks to get the other one to work with no success. I've tried numerous drivers, pc, cable etc... I've compared the settings on the phones *#0808#, *#2264#, *#0011# *#*#4636#*#* and any of the others I've found. The ports show up in device manager without any issues.
Android version 4.2.2
Kernel 3.4.0-784654 [email protected]#1

My question(s) are:
1. Is there a way to get qpst to recognize the com port without coming back with "no phone"
2. Is there another tool or software I could use to do the AWS flash?
3. If none of the above, Would it be possible or even correct to copy something from the working phone to the non-working phone? of course without damaging the IMEI/ESN...
Instructions are helpful as I am new to this, but very interested in learning.
Thanks in advance to anyone who can help!!
UPDATE!!!!!!!
I did a factory reset while plugged into the usb and qpst picked it up upon rebooting. I don't however find this as a solution, but Now I have the AWS enabled.

I have a similar problem. I just got my gs4 active , and while I get 4g service, most of the time I just don't get data at all. I already rooted and enabled hspa from a guide off "high on adroid" but the problem persists. I'm determined this is a at&t locking there bandwidth issue but I don't know what else to do in order to free my phone. Any advice would be appreciated. .

He does not need an AT&T modem flashed on his device. That would most likely result in a brick.

Ok you need to give ATT the IMEI number from one of their LTE android devices. Just go to the store to get one from one of the demo devices. Then your account will be provisioned for LTE.

I tried to do LTE only and it has the right network code, but it won't activate. I checked my ATT online profile and it doesn't have a "LTE" data plan and I think that is the problem. I'll try again tomorrow once it takes effect and report back

The guy above is correct, you need at&t to register your imei into their network to access their LTE.... They should do it for you no problem, just give them a call....however I wouldn't be surprised if they don't! Another way is to find someone with an extra LTE phone and just activate that imei and your LTE should pop up

If he registers his T-Mobile S5 on AT&T he will still have problems. AT&T won't recognize the T-Mobile IMEI number, and therefore it will list as a GSM device.
He needs to find an IMEI number of one of AT&T's LTE android devices. Once he has called AT&T CS and have had them provision his account for LTE, then he can just pop in his AT&T sim card to his T-Mobile S5. He'll get LTE then.

What he said.
What are your APN settings? I have T-Mobile S5 on AT&T and have LTE working.

Just wondering where did you unlock the phone from and how long did it take to get the unlock code?
Thanks for everyone's help. I am good to go.
I took a SIM from another LTE device. I think it does need to be registered as a IMEI from an ATT device and that was the problem.

Now that you are getting AT&T LTE on the T-Mobile variant, can you please comment on LTE signal strength? This is a deal breaker for me. When I had the TMO Note 3 on AT&T, LTE reception sucked. If you can compare it with an AT&T branded phone, that would be great.
Another person using the G900T. Congrats
My experience is that coverage is just as good if not better. Same radio, same antenna, I wouldn't expect it to be any different?
The TMO GS5 has all the needed ATT LTE Bands no need for a radio flash, I'm using one on ATT now, have gotten LTE from day 1, as stated only requirement is the sim has to be originally activated on a LTE ATT device and that the APN is set properly.
What kind of speed is everyone getting with the tmo s5 on att network? I have an att s5 next to a tmo s5 and att s5 is getting 50mbps vs tmo at 20mbps. I am wondering if I needed to configure something on the tmo devices?

Check your APN setting. The T-Mobile S5 should have the same exact APN settings your S5 has. Can you also comment on LTE reception on the T-Mobile S5 using AT&t?

APN is exactly the same as AT&T one. Reception is also same as AT&T one but the speed is a show stopper if it's half the speed. Any one have any ideas?

I wouldn't sweat the speeds, unless you keep noticing it. Try again later. Perhaps the T-Mobile S5 needs a modem update? Keep us posted.

I would also like to do this, but I just want to clarify something. I just bought an AT&T S5. Brand new, unopened, still in the box. I want to swap it for a T-Mobile S5, as the bootloader is unlocked. If I keep the AT&T SIM card before I sell it, and put it into the new Tmo S5, will I have any foreseeable issues? Will it work just like that, or will I need to retrieve something from my S5 before I swap it?
Thanks.
EDIT: I should clarify that the device is unactivated, and when I do activate it, I will be porting my existing number from Verizon.
