[Q] Use AT&T iPad SIM on T-Mobile Galaxy Tab?

Ok, so I would really like to transplant my micro sim from my iPad, seeing as though I got the $29.99 unlimited plan & pop it in a T-Mobile Tab. Would this work? I've checked & the T-Mo Tab does support At&t's frequencies...

It's not a micro sim card, just a regular SIM. So not sure if you can get an adapter to make it fit?

It's a regular SIM card. I tried but the tab asked me for the unlock code. I guess that's another dead end. I talked to tmobile and they told me I have to wait 40 days for the unlock code. Any ideas?

1) you need to get around T-mobiles SIM lock
2) the tab is 2G quadband, so GPRS will work. But you won't get 3G on AT&Ts frequencies

flashing a rom should disable simlock. am i right?

no it will not

There is an unlock guide in General now for this.
Just FYI.

I tried it and my tab is now unlocked, but I cant get ATT to work. It connects and disconnects from the ATT net. I have played with the settings but no luck. Cant even get 3G with ATT. Help please!!

Have you set up the AT&T APN info?
Settings/Wireless and Networks/Mobile Networks/Access Point Names/(menu New APN) then enter the AT&T network info, which you can find with a quick web search.
Until you have that information, it can't connect to the internet. The T-Mobile APN is the only APN that device knows at the moment, and even that is hidden when using a SIM from a different network.

to get your tmobile Tab to work on att u have to settings>wireless and network>mobile network. then change Network Mode from AUTO to GSM Only
then you can use this on ATT with EDGE internet

What about putting an iPad microsim with adapter in the AT&T galaxy tab? Would any tweaking need to be done? Would 3G work or just EDGE?
I have no interest in voice on the G Tab.
thanks

I did some checking and was able to verify that the iPad microsim in the AT&T g tab will work. The poster didn't specificy if it was 3G or edge but I'm guessing it was 3G.

You will need to use "broadband" as the APN name for the iPad SIM data plan.
You may also need to choose "Supl" as the APN Type, had this issue with the Dell Streak,
Edge would work until i went to use Google Maps then it wold disconnect.
You will also want to set to 2G only or GSM as the US TMobile Tab doesnt have ATT frequiencies for 3G

[Q] How to Unlock my mobile network settings?

Hi,
I recently bought a HTC Surround (AT&T), im from Costa Rica and we don't have AT&T as a carrier.
The phone works great with the GSM band but when i try to look for any 3G settings (using 850Mhz band) i cant find any options.
According to an article in the internet (i cant post any links yet) there should be an option called "Mobile Network" where i can turn the 3G on or off, so im guessing AT&T disabled the option (phone doesn't have any 3G sign on the sign bar at the top just the antenna bars).
Is there any way to Unlock the 3G options on this phone?
Thank you.

Help me out a little with your request. The place to turn on/off data is under cellular in the settings page. However, I haven't found "Mobile Network" on mine. However, I did download HTC Connection Setup which allowed the phone to search for various carriers and automatically set up the connections. That program is in Marketplace under HTC apps.
BTW, is your phone SIM unlocked?

Thank you for answering ...Sure ill help you with what ever you need... we might be able to narrow down my problem... lets see
1. HTC connection: yea i tried the app actually i have it installed on my phone but its giving me a message saying "Carrier doesnt exist in the data base" that i need to go a create apn (isnt that for phone internet). so i cant use the application, our carrier here is called I.C.E.
2.The band Costa Rica is using for 3G is the 850MHz. my SIM card is linked to a GSM account (1900 MHz) but the phone should be able to recognize the band tho, isnt that right?
3.how do i know if my phone is sim lock? i just placed my GSM SIM card inside and its working, do i need to try with a different card?
4. how does 3G works in this phone? is it configurable?

I'm pretty sure you are going to have to configure an APN for it to use 3G. As for band switching, I don't think it's possible with the current interface (at least on AT&T). Perhaps there are some registry entries that we will soon be able to access when some of the WP7 developers make headway, but right now, there is nothing of which I'm aware. If you can call on your network, the phone is already SIM unlocked, so no need to worry there.

I found some nice info about switching 3G or 2G etc... which it helps but i think it didnt work on mine.
Does anyone know how to set the HD7 (or surround) to 3G only?
Dialer> ##3282# Call > Settings > 3G only.
But in my case what i saw after that was that all the antenna bars were gone and then it went into no service then picked up signal again. After checking the settings after dialing again it was set to automatic again and if a switch it to 3G only it does the same thing again.
So im guessing it didnt work, ill try to talk to my carrier and see if we can create an APN to handle the 3G.
Is there a chance that the 3G feature is locked by AT&T?
Thanks for all your help if by any chance you find out something else i will appreciate the help.

Well apparently i got it fixed my phone seems to be working on 3G right now, i have the 3G sign on the top bar.
To make the story short.
I just configured my internet, added the roaming options and then tried again ##3282# only 3G and it worked now its showing 3G next to the antenna bars.
Thank you jwzg for your help.

No, you don't have to do any special configuration. I think TMobile bands for 3G are different frequencies from ATT, so sadly, I think you are never going to be able to have 3G connection on your Surround while you are on TMobile. Regards.

mmmmm tmobile used different bands
mmmmm input to sim movistar in htc, rigth in connection setup appers to configuracion of Nicaragua chance to Costa Rica and input sim ice connection don´t exist in data base... :-( mms is not working!!!

[Q] unlocked tmobile hd2 no data connection??? please help

i have a tmobile hd2 and its carrier unlocked i am using it with ATT and i just recently lost all data connection to my phone. i have an unlimited data plan that was working perfect until just recently. no internet or mms not even weather!! only can use wifi. can anyone help? thanks

Have you tried
*#*#4636#*#*
dial this and then go to phone information.
Have you run the ping test?
Checked what Current Network says?
Checked to see if there is anything listed under =======DATA======= ?
Have you tried to put a friend's TMO sim in the phone to see if data is restored?
All the data you can provide could help solve your problem. As is, the problem might be a little ill defined.

If you are running Windows Mobile on your HD2 from the home screen touch onvStart Menu/Settings/Menu/All Settings/Connections/Connections. Then tiuch on the adcanced tab and then touch on Select Networks and make sure AT&T is the selected network. Also tiuch on the Task tab and select Manage Existing Connections. While on the Modem tab make sure AT&T is selected and under the Proxy Settings make sure the box beside "This network connects to the internet" is checked.
Ok if you are running Androud then go to Settings/Wirless & Networks make sure allow data connections box is checked. Also go to Networks/Vertualy private networks (VPN) and make sure your AT&T VPN is corrwct.

i have fixed the problem! i was running the tmobile 3.14 rom udate which sucked and i just flashed an energy rom and alll is working again thanks for the suggestions

Same Problem
Someone please help and know that I know little to nothing of technical terms! I have the same problem. I have a T-mobile Hd2 and had Android put on it. Right at first I had a data connection then all of a sudden-NO DATA. I'm so frustrated! I checked the setting for using the phone as data connection SEVERAL time. I can get wifi but no data otherwise. PLEASE HELP

Try:
Menu - Settings - Wireless and networks - Mobile network - Access Point Names - menu button - restore to defaults, and follow the simple instructions
This should place the latest APN from your carrier on to the phone - may need a soft reboot

Hi, I'm currently trying to get my T-Mobile HD2 to work properly on NTT docomo, a Japanese cell carrier. I moved here at the end of May and have been using a data-only SIM through bmobile, a provider that uses the same towers as NTT docomo and it worked perfectly, however I switched to a voice and data plan and now I have no data connection. Voice works fine though.
I followed nenol's steps and under =======DATA======= it says, "State: DcInactiveState disconnected with last try at 9:49PM fail because Activation Reject GGSN" What now? Ha

Hello Guys,
I will receive my new Nexus7 today from US.
I have some points that I can clarify:
1). Yes it is a 3G device but does not support voice call only data is supported.
2). All Indian 3G sim cards will work (micro sims).
3). Though, sms can be used using sms apps like GOSMS Pro.
4). The device has a voice calling chip enabled but it is locked on the radio level and till now developers have not devised a way to unlock it or get it to work, you all can find lots of discussion on this on different user threads here on XDA.

not working in bsnl cellone
I own a nexus 7 in india originally shipped from us. The At&t sim works jus fine, with that my n7 detects APN and other things perfectly. But when my bsnl cellone Sim cut to the micro Sim size is inserted, it shows no service and there isn't any APN listed.
I tried the following
1. setting up APN manually. but n7 doesn't save the APN settings that I enter
2. choosing cellone network manually in the mobile networks section. but it says cannot connect to this network, try again later.
this is my experience I am trying other options but no progress so far. any suggestions?

I'm using n7 3g which was brought here in India by my cousin with tata docomo photon 3g sim cut to size. Everything rocks and blazing fast

After you enter APN settings, before going back you must click 3dot menu and click on save for it to save settings. Then go back and select that APN.
If you just go back, it wont save it.
I have 3 N7 in family for 3 members on Airtel, Vodafone and MTNL respectively. All working just fine with 3G.

Nexus 7 works fine on any 3g micro sim plus wifi.
I also received a voice call on my landline in US from India from the Nexus 7 through a google voice activated number (using grooveIP) and when the device was in the US in November of 2012 - could make voice calls to India through Vonage extensions
Just my two cents

[Q] Sprint S4 - cannot connect to internet via gsm chip

Hi All,
I have a Sprint S4 (SPH-L720) which i got from the states. I plan to use this in Canada...was able to root/unlock the phone via SIM Unlock Method posted (http://forum.xda-developers.com/showthread.php?t=2415587&highlight=sph-l720).
My issue is that i am unable to browse internet or use any apps needing internet on the GSM/UTMS network mode. I have a Rogers LTE chip that i am using and am able to use the phone (voice calling) with no issues. I can use internet on wifi but am unable to when trying internet via the phone chip...i do have a 6GB plan with Rogers and can browse internet when used on another phone.
I had to downgrade the Baseband to MDL/MDC to sim unlock the phone and have later installed MF9.
The software version and baseband now on the phone is: L720VPUAMF9. Earlier had an issue that the wifi was not working, option was disabled...(was getting a message - that an app is trying to connect...) this got fixed after i flashed the kernel version.
Can anyone advice how i can use data from the GSM network and not wifi.. has anyone faced the same issue.

Add your APN for your gsm sim under APN settings.

Thanks guys...i was able to get the APN settings and now my phone works on data from the lte chip inserted.
Now my issue is that my phone does not show LTE....i have another S4 with Rogers and i verified running speed test on a friend's phone to compare...my specs on the sprint phone are almost 40% lower than his phone on the same network..ran from the same location (apt). I tried various combinations i.e. (LTE, LTE/CDMA, GSM) but i can only get 3g or H+.
Any suggestions that i can try...Thanks!

This phone doesn't have the proper bands to work on Rogers LTE.
