Use T-mobile Htc Hd2 On AT&T 3G Network?

Hi guys, i have already searched the forums and cant find anything related to my title. Basically i would like to know if i could use my hd2 on at&t 3g network and how can i do it. I know i can unlock my hd2 by asking t-mobile but would it work on at&t? Thanks in advance

yeah it works on at&t network but not as 3g. It gets E which is the edge. If you search the forum there's a cab file that will program the phone so you can use data connection with at&t network. I got my phone unlocked via tmobile and have been using it with at&t for a couple weeks now without any problems.

SO you are basically saying that i can do anything i can already do with the phone on t mobile on at&t but except have 3g? So i would have to use edge as my data connection for internet? And how does sms work? Any settings to change to get it to work?

Install this cab file, its all you need to do

These are the att settings everything will just work
on att, you can use gprs/edge , but of course no 3g

You have to have T-Mobile account to get the HD2....they don't sell them unlocked... after 40 days of use on a t-mobile account, t-mobile customer service will provide youw ith an unlock code, not before...

I'm wondering, if the radio can be flashed to support AT&T 3G band, or components are different...

No, can't be flashed to work on AT&T 3G. You would have to get the Australian Telstra 9193 model which uses the 850 band that AT&T uses. That's the only way to use AT&Ts 3G with the HD2. The bands are set in the hardware.

how did you get the unlock code from t-mobile before 40 days of activation. That is what they told me when i asked for the unlock code. could you please share the secret....

this is incorrect. anyone can get the hd2 without contracts @full price of 450 plus tax. they will also unlock it in 1 to 5 days if you paid full price.got mine from wirefly, and had it unlocked in 2 days.

I have an HD2 on AT&T and everything works, but not fine! If I am browsing the internet and the phone tries to update the weather or mail, really anything else that accesses data in the background it will stop my data connection everywhere. It seems the only way to fix this is a hard reset sometimes, at the very least I have to exit the browser, open the task manager, kill everything, and turn off the data connection in the wireless controls and turn the data back on... My questions to the others who are using this phone on AT&T are 1) are you experiencing the same problems? 2) What did you do to fix this. I have installed the above mentioned cab file for settings and I have also manually entered the settings. I would love the phone even though it only has EDGE except it cant hold a data connection for more than 10 minutes at a time.

Well due to the type of connection that EDGE is, you cannot be on the internet and talk on the phone at the same time. This would also go for all applications that use the data connection...only one at a time. This was the case on the pre-3G phones like the HTC Wizard (Cingular 8125).

The phone cannot and will not get 3G when used on the AT&T network, despite what your icons show...the hardware simply isn't capable. Period.

Bought my unlock code through ebay for $14.00 and had the phone unlocked in 20mins. HD2 works great now.

G = GPRS
E = EDGE
look them up on wikipedia if you want more info but.....
GRPS is older and slower than Edge, GRPS max speed in ideal conditions is somewhere i the upper double digits/ lower triple digits. You might be lucky to get into the 200kbps range with EDGE.
In the end both suck compared to being able to get tmobile's 3g signal which ive personally seen hit 5mbit/s here in tampa now that HSPA+ is deployed. Being able to get ATT's 3g might get you right around 1mbit if lucky. I dont know what if any plans ATT has for HSPA+ deployment

I used this .cab file and while I can browse the web, I can't seem to send MMS pictures using my AT&T sim, are there other settings I have to change?
EDIT: I found the answer here, after a bit more searching! Thanks all, forum.xda-developers.com/showpost.php?p=6695081&postcount=13

I just bought the hd2 and planning on unlocking it to work on AT&T. I know that I will be getting Edge instead of 3g. But can someone plz explain to me how does it work as far as data plans and mms. Do i need to have a data plan to send mms or mms will be sent through edge. and as for data and web browsing , do i have to have a data plan or since when i go online i will be on edge so i dont need a data plan

[Q] tmobile and unlocked Samsung Tablet

I apologize because I think I may have posted my questionin the wrong place two days ago. I'll see if I can delete it. I hope a few people here can answer me.
My question is that I already have a voice data account with tmobile and SIM card for that account in my Galaxy S Vibrant. Can I remove the SIM from the vibrant and place it in this particular International unlocked P1000 Galaxy TAB to use this P1000 as phone and data just by moving the SIM card? Or do I have to still notify tmobile that I am moving the SIM to this unlocked P10000 device? And will all features of this international version then work....the phone and 3G data with my SIM from the working Vibrant? If I can just move the SIM card is there anything else that I have to know or have to do?

All US carriers consider Samsung Galaxy Tab as a mobile broadband data device and make difficult to walk around this decision.
Since you are going to get a Tab not from T-mobile, it will not have your IMEI number recorded and might treat your Tab as a phone allowing for both voice and data. The issue might be only that you will not get 3G for data because software and hardware do not support unique 1700/2100 AWS frequency bands utilized by T-mobile in the US.

Do you have the phone dialer icon? If not you will need to flash a rom so you have a dial pad.

Thank you both for some answers.
The reason I was looking at this imported version was because I read that this Samsung tab already allowed telephone and since I already had a working 3G and telephone SIM from tmobile I thought this was the way to go. I really wanted this Samsung Tab to do telephone so that was the real reason even looking at this particular item.
No I have not ordered this yet. I wanted to ask the questions BEFORE I paid the money to find out that it will not work in my situation?
So what I am reading from both of you is
1. I probably will not get 3G, and
2. I would need a dialer Icon from somewhere.
Not getting 3G is a "do not purchase this" issue then for me.
Any ideas on the Samsung Tab then? I do NOT mind signing it up with tmobile, I just also wanted it to do bluetooth phone, 3G and then only need to carry this one device.
You guys are great
Thank You

The T-mobile tab can be unlocked. After it is unlocked you can flash it with a European rom and Roto's modem swithcher. You can then run 3G on any carriers sim card and switch to 2g (edge) and phone with T-Mobile using Roto's modem switcher.

WoW. Thanks for that info.
Wonder if you do all this and will hear incoming calls if you are in 3G mode. (i guess this is what the Roto's switcher does, it places it in 2G or 3G). Then if you could/would hear it ring while in 3G, for an incoming call you would then have to switch to the 3G mode with this Roto switcher? Trying to get the call before voice mail kicks in? (what is it, an icon for an on-off type thing of its installed software).
Has anyone actually done any of this?

Yes its been done by many Tab owners. Search the galaxy tab developers section for how to flash roms, modems and kernals. You'll find a treasure trove of information on how to improve the Galaxy tab. The Developers here at XDA are an incredible group of people and most are willing to share their development findings with other Tab owners.
Good Luck.

Do I understand you correctly saying that T-mobile Tab after flashing can get 3G and voice phone on any carrier Sim?
This would be my "dream". So far I can only get either voice with phone Sim or 3G data without phone capability. BTW, the latter requires Sim with paid data service separate from smartphone. Roto's swither is just a utility flashing either phone modem or 3G data modem.
Would you mind to give more details supporting your post.
P.S. European Tabs have phone voice capability and a dialer out of box. Not extra flashing is needed.

Voice + EDGE data OR OR OR 3g data/ no voice NOT NOT NOT both!!

You cannot get 3G data and voice at the same time on the Galaxy Tab. With the modem switcher you can switch between 3G data only and 2G (edge) data and voice.
Until the development community can come up with a method to run 3G data and voice at the same time (if possible) the modem switcher is the best answer to the problem.
Also the the T-Mobile Tab can be unlocked so that any GSM carrier's sim card can be used. This allows you use the sim cards from Simplemobile or any other GSM carrier and not be locked into a T-Mobile sim card.

Anyone live here in MD and want to make some money setting me up doing this thread hack/install for me?

I am a T-Mobile customer and here is set up on my T-Mobile tab:
1.Tab running Roto's JME v4 (European firmware that will allow voice+edge)
2. Roto's Modem Switcher (switch between 3G only or Voice+Edge)
3. My old Vibrant SIM card (Voice+Data)
4. Broke IMEI so i could use my Vibrant SIM to go online and stop getting re-directed to t-mobile site.
So basically i use my tab as a phone now but only getting voice+edge, if i want faster speeds i switch over to 3G using the Modem Switcher. The only way you can get both voice+3g is if you unlock the tab and use AT&T sim, if you want to use T-Mobile sim that option is not available unless a modem comes out that allows both voice+3g.
Hope this helps in making your decision.

Hello and thanks very much,
Seems that you are a match to my scenario. Are you happy with everything the way it works now (voice/2Gdata).
Do you have Caller ID working in any setting/switch?
And to make sure I understand this part. If I am in 3G mode I will NOT ever know of an incoming call by any pop up or beep or anything? The only way to know if some one even tried to call is to go to voice mail from 2G/voice being switched? (se, I am not a voice mail user. i have my Vibrant tmobile voice mail turned off at tmobile.)
So what i read at the top of this thread about having to unlock it is not the case for me?
Do I have to remove anything or add anything else?
Having to do anything at all other than these 4 things you listed for me is not needed?
That's very interesting. How do you "break" IMEI?
And these installs that you did list, is this the exact order to do these things?
And what about the thing where someone said I need a phone icon?
How do you switch to phone mode and dial?
BTW how is it as a phone with Bluetooth device? How is the volume (at both ends). Can you hear okay?
And I think one last question. If you happen to be in a wifi spot and using the tab in wifi mode, does the phone work at all?

No true. If you flash the at&t tab with Roto firmware, and install the bell modem, you can have 3g and voice with an at&t sim card, but again, at&t tab only does this.

Dear noreturn
If you so eager to get it and need help send me PM. I am almost your neighbor.
I would not recommend you breaking (meaning erasing file containing) Imei.
You have two other options
- get At&T tab, unlock it use on Tmobile with Vibrant sim. You will get voice and Edge which is very usable around dc-md-va. 3g will be only on att.
- get European Tab that is unlocked and use it on same way as #1 but no extra firmware flashing is needed.
Unlocking of either Att or Tmobile Tab is easy the same is true about flashing. however it takes more time.
Caller id works as on any phone.

Yes I really do want to get this samsung with voice.
So are you saying get this version of the Samsung tab and use my tmobile vibrant SIM?
Then install that modem switcher thing is all? And I guess I read about a dialer icon or something?

European Tab has everything for voice and Edge but Tmobile tab just cheaper.
Dialer comes installed with European, on Tmobile it appears after flashing.
Hope you understand your options. Modem switcher helps only if you have paid data service or erased your Imei. The last case is legally questionable thats why I would not advise it.

True. I should have clarified my response in that I was referring to the T-Mobile version.

I have the Hong Kong version,which has the same 3G frequence with At&t.
I use a At&T sim card and has 3G or H on phone and data works perfect.
For t mobile sim card you will only get edge for voice and data.
If you have any question you can email me.
Jimmy

Its kind of pricy,it cost me almost 700.00,but you don't have to change anything.
It depends on what carrier you use Tmobile 2G, AT&T 3G.
I love the device.you can hold it by one hand and use other hand to surf.

Tmo tab on uk network?

So i am currently in the uk (northern ireland to be exact) when i try to select a network (O2, Vodafone, tmobile) it wont register, it sees the network but it wont connect to it. Besically i am using the tab with my tmobile sim not a local sim, and the tab is still network locked to tmobile. Any ideas on how i can get it to register to a local network? I am not looking to unlock the tab (not right now at least) and run it with a local sim just trying to connect to a network just in case i need to make a call.

Do you have "WorldClass International Roaming" enabled on your plan?
Regards,
Dave

Well i am not sure,i actually checked my account and all i see is somethibg called world class international service, my wife has this option on her line but her phones does not connect either so i not sure thats not the only thing that needs to be activated. There is no way for me to select that service on my line. I also have an old phone wich was unlocked and using a prepaid sim card and it does not connect either. Could it be the sim that is not allowing to connect?

You can add that above mentioned roaming service for the time you are away. I think you can do it through the att.com website. But get ready for a shock - it's a buttload of cash for data and cell.
You're at a pc, right? If it's windows 7 and you have your cable, why not unlock it and buy a local sim? That's my solution when I'm out of the US.

As metioned on my previous post my wife has that service on her line and she still cant get it to register on the local network. Might be the sim we have,tmo, its not letting us connect. Ill have to call them when i get back to the us and find out why. I am waiting to contact tmo to get my unlock code for the tab, i am not confortable using adb.
Sent from HAL 9000

You can follow the cut-paste steps from Roto to unlock tab without adb. Just get a terminal emulator from the market, and open it, then do the copy-paste in the emulator. It's cool!
Did you check your network settings to enable roaming?

I have also noticed that the GPS was not working either, I was driving and had GPS test running for over 5minutes and it never locked the most I got was 4 satellites but didn't lock on any of them. Mind you I was driving out in the country and clear skies no idea why GPS would not lock in northern Ireland.

When I can't get a lock, like right after flashing a new rom/kernal, I go into recovery (power +volume up), and clear the cache partition (don't factory reset!), then I use a market app called Here I Am 2 to get the first position lock in a new region or country.

I did have roaming enabled and still nothing, i will call tmo to ask and see what they say.

The only way to know if you are unlocked is by using another carrier's sim. Just borrow one from a friendly local, or buy a prepaid sim to use for local calls.

I did use the sim to unlock my tmo vibrant and it worked with no issues, so what am i doing wrong? Do i need a new modem for the sim to work? I also tried using the apn settings from the vibrant running the att sim and nothing, tried apn settings from google and nothing, what gives? Any advise? Thanks.

[Q] use ATT laptop SIM in ATT GT

I have a laptop that has a ATT SIM card with data plan. I tried to use it with my ATT Galaxy tab but it didn't work! I easily reach my 2GB limit on my TAB and I was hoping I could use the one in the laptop since I rarely use it. I did SIM unlock (although both are ATT SIMs) yet didn't work.
Any ideas if this can be done and how?
Thanks

Hello.
Although not specific for you, I've done similar with my Canadian Bell Android phone with unlimited data plan, and Bell Galaxy Tab with pay per use plan.
I now have galaxy tab with unlimited data plan, provider is none the wiser.
Your issue might be the apn difference between the tab and the apn set up on your laptop's sim plan.

Thanks for your reply, but how did you do it? or it did work right out of the box without any adjustments?

Anybody have an answer or work around would be much appreciated

Find the APN settings from your service provider for the sim.
Then install APNDROID PRO and enter them settting from above. Install the sim and your laughing! !!!

Would appreciate any help.
Thank you

Just a thought, go to settings /more networks and make sure you have the correct network checked

New to verizon galaxy s 5
The network was correct . Wondering if im in a bad area. My Iphone 4 works fine. Might be AT&T

Wait... you put an AT&T sim in your phone? This is a Verizon forum. If I misunderstood, please tell me.

Just to be clear because you didn't state it in your post, you must unlock your phone prior to using a non-Verizon SIM. You can sometimes get these unlock codes from Verizon but you can also buy them online. I've used GSMLiberty.net with success before. After that, you should be able to pop in your SIM from the new carrier and begin using it right away. In some cases, you may need to manually add the correct APN for your carrier. Find these settings under Settings > More networks > Mobile networks > Access point names. Click the little plus icon in the top right and manually enter AT&T's APN information. You may need to Google that as I don't know AT&T's APN info.
I use my Verizon S5 on T-Mobile's networks with absolutely no issues, I assume it would be a similar experience for AT&T as well. For me, I put my T-Mobile SIM card in and could make calls and receive texts, but mobile data and MMS was not working properly until I manually added the correct APN information. After that, MMS, 4G LTE data and everything is working flawlessly.

You do not need an unlock code for a LTE Verizon phone. These phones are already unlocked. One must set the correct APN.
Do not buy an unlock code!
I have used my Verizon S5 with att and t-mobile.
Good luck.

Thank you for your posts. Most of the phone works. When I leave a wi-fi area my phone goes to emergency calls only. When I go back to a wi-fi area the normal call service works again. I'm new to verizon and samsung. Wanted to use straight talk because i didn't feel like paying a fortune for service. I'll get it figured out some way.
Thank you again
