Do I need a T Mobile Sim?

I have searched and read the wiki but I couldn't find an answer which I'm sure has been asked before:
If I get an unlocked G1, do I need a T Mobile (UK) sim? I appreciate sim unlocking it means it should accept any sim but are there any features that only require the T Mobile network connection. I presume it won't update any more if I leave it on Vodafone for example?

No, you don't.
Any SIM with data plan will work just fine, only you'll need to add APN manually and you will not be able to use OTA updates.
I've bought about week ago G1 in sealed T-Mobile box, but it was unlocked and i put my O2 SIM and during activation entered data for O2 APN and got i work without any problems.

Actually you will still get the OTA updates even if you arent on tmobile. Google sends out the updates so all you need is some form of data connection, wifi or via your provider.

[Q] Focus on T-mobile?

would the samsung focus work on tmobile network if i had the unlock code?
3G and all?
thanks i've searched online and didnt really find anything helpful

if you get the focus unlocked, it will work on tmobile, but you wont get the 3G speeds. Only EDGE, since the focus does not have the required HSPA frequencys used by tmobile.

thanks a lot, thats all i needed to know, Disappointed tho

Reviving this thread. So I have a Samsung Focus unlocked on Tmobile and I cannot get data to work. Any ideas on what could help? i have already added my apn of internet2.voicestream.com

Have you tried epc.tmobile.com

yes I have with no luck but thanks

in the usa depending where you are they either use epc.tmobile.com or wap.voicestream.com might try the network profile app too... i know samsung has addressed this issue and is in the process of fixing it to where when the unit is unlocked the settings from any gsm carrier will work... there is also a homebrew app somewhere that has worked with mixed results too...

ive tried those apns as well. thanks. and i tried the network profile app too any idea where i can get these homebrew apps?

probably in this forum or the wp dev forum here.....

Samsung Focus Unlock Code
I hope this isn't an issue, as I just ordered a Focus to replace my wife's v1 iPhone on T-mobile USA.
Anyone know a good place to get an unlock code?
The one on unlockcellphonecode.com/ is $45.00 which seems really high to me.

As far as the frequency concerned, AWS spectrum used by T-Mo is 1700 and 2100 MHz.

ATT Samsung Focus on Tmobile
To anyoe else thinking about getting a Focus to use on Tmobile USA network....
I can confirm everything is working and this is how I got it to work.
Everything works except obviously 3G because att and tmobile use different frequencies for 3G (until the merger at least) 2G works great though.
First thing you need to do is either get an unlock code from ATT (unlikey) or go to FastGSM.com and for 19.00 you can get your phone sim unlocked, so that your tmobile sim will work.
Now your phone works and my data was working out of the box as well.
However, you will not be able to send or recieve MMS messages.
To fix this, go to the market and clck on Samsung Apps, then install their Network Configuation app. Open the app and change network from ATT to Tmobile USA and now MMS will work perfectly.
Hope this info helps someone else.

WOWWWW I was searching to see if an unlocked ATT Focus with be able to MMS on T-Mobile US network. Thanks for the information.
I have a Focus and called ATT for unlock code. They said the unlock code will be provided after May 8th. So waiting for a month before I can use it on T-Mobile US.
My only concern was whether I would be able to send and receive picture messages. I hope your solution works next month!!

[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?
Sent from my Dell Streak using XDA App

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

Just FYI.

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!!!

Use of Samsung Focus in UK?

I was wondering, if I was to order a SIM unlocked Samsung Focus from america (there are a few on ebay) would I have any problems using it in the UK?
As far as I can tell it has the same GSM bands as UK phones, but I am wondering why it wasnt launched in the UK?

I think you will have trouble configure MMS for use with your own network of choice (known issue and seems no solution so far). Also, it may or may not support the 3G frequency depending on which band your carrier uses (Focus only supports 2100Mhz band outside of US).
In UK, you should just order the Ominia 7. Same phone (and looks better than Focus, IMO) sans the SD card slot. But with the amount of trouble of getting any SD card to work reliably with Focus, you might jsut forget about it ever had a SD slot in the first place.

I ordered mine to Norway from ebay. Everything but MMS works perfect, and the MMS issue can be fixed with an app from the Samsung Zone in the Marketplace which allows you to change the settings that at&t have hidden away.

I got the Samsung Focus recently and I'm using it on Vodafone UK. I notice that sometimes despite the phone saying full 3G there's no connection and I have to reboot the phone to get a data connection. Anyone else had this?

I have an unlocked Focus too... for those that have successfully got the 3G to connect - what tarriffs are you on, and how did you get it setup??
Cheers

Samsung Focus in the UK
I have a Samsung Focus from Ebay. I have unlocked the phone from fastgsm which was instant and simple to do.
I have the internet and 3g working fine so far by simply adding the Vodafone APN settings in the menu. I haven;t tried mms messages but don;t really use them anyway but think they should work if you use the samsung app for configuring the phone fromt he store.
Just a quick comment. I can;t get the radio to pickup much. I have changed the region to International but I am still getting a terrible signal although I do get some stations they are quickly lost if you move at all. Any help?

^^ I have the same problem with the radio. Unlocked via FastGSM.

howdy. I've got an unlocked focus on vodafone pay as you go SIM; they can't seem to give me any APN etc settings that allows the internet to work. Do you mind me asking what you've entered into yours??
