[Q] International SIM Card - Unlocking

Greetings Fellow XDA Friends,
I have a family plan with my girlfriend we both have G2's running latest CM7Nightly and we use a 3rd MT4G running RoyalGinger 3.0.
I have called tmobile and had them "unlock" them for international calls as well will be going to the Europe this Fall in October.
They emailed us an unlock code.
Question 1. Do I need to purchase an intl sim card insert it then use the code they gave me before unlocking?
Question 2. Can I unlock them before going overseas and then replace my U.S. SIM card and continue to use this?

If you rooted your phone with gfree its already unlocked...

Sorry still learning,
Sorry for the ignorance. Just learning as fast as I can, If I rooted all 3 phones with visionary then they won't be unlocked?

My understanding and explanation would go like this.
Using the unlock code simply allows the phone to be used internationally with another carrier's SIM. Applying the unlock code simply opens up the functionality to read another SIM card.
Apply the unlock code, and you can put in any SIM card from a carrier that runs on the same frequencies as your phone. Put a T-mobile SIM card back in and the phone will work as it does now.

What he said is correct, and you'll only need to enter the code after inserting a different SIM card into your phone. When you get home, plug back in your other card and you're still good to go. (Or now you could go and switch carriers without breaking or signing contracts )

Or just unlock with gfree and never have to enter a code...

Visionary only gives you root, not S-Off. If you are on CM7, then you must have S-Off (in order to be able to flash any custom ROMs). Do you remember how you got S-Off? You probably did Visionary than gfree, and just don't remember doing gfree. Did you use ADB, and enter any terminal/command lines on your desktop computer? If so, you probably did gfree.
If you did gfree, then you have Subsidy Unlock, which means your phone is SIM-unlocked. Nothing else to do, just slip the new SIM into your phone and use it.
Some people have had an issue, where applying the T-Mobile SIM unlock code renders their phone unable to read any SIM. So I would stay away from the code, and do gfree, if you have not already.

Has anyone used Rebtel? http://gigaom.com/mobile/free-international-calls-android-rebtel/ My gf and I are moving to the UK
I am wondering should I just cancel my tmobile account? Is there a way out of the contract? What do I do?

Unlock Branded [SoftBank Japan] Desire HD, No Sim Card

Hello there,
For the past few days I have been browsing through the XDA pages but was not able to locate the necessary information. May be I was looking under the wrong terms or key words.
Anyways, I have switched from iPhone to HTC Desire HD. I got it second hand and it has no SiM card. Basically, when I insert my uSiM it shows emergency call screen only.
I was browsing through XDA and as far as I got it I first need to activate the phone with the necessary sim card in order to unlock the phone. Is there possibility to `hactivate` the phone with no original sim.
And can you people help me to locate necessary information on the site?
Thanks a ton in advance!
Peace,

Anything on this one?

I wish I could help. I have rooted my SoftBank HTC Desire HD and used loads of roms but I got it from SoftBank (with a SoftBank sim) so I haven't explored unlocking.

Let`s say I can borrow a SIM card from a friend and activate the phone for a while. Could you please direct me @ step-by-step rooting and unlocking guide. Coz, I am bit confused.
As far as I got it, once I activate the phone I need to install Visionary on it via mSDCard. And then I can use certain tools to unlock the phone. Is my thinking correct?

Backup APN:
Get the program APN Backup & Restore - and backup your APN (the SoftBank internet access login and password) to your SD Card. It gets saved as an xml file. (Call it something you wont forget.) Here is the APK of the APN Backup & Restore program to keep on your SD Card.
Then when you do flash a new rom - instantly disable data, run APK Backup & Restore, delete the APNs that come with the rom (even if they say SoftBank) and restore your own SoftBank original one. (Then you can connect and you know you will not be billed incorrectly for using the wrong access details. (This happened to me a few years ago with Windows Mobile and SoftBank)).

[Q] HTC Phone 8s Unlocking Procedure from box

So, i've received right now my new HTC 8S from Telecom Italia Mobile in substitution of my old jailbreaked iPhone 4.
So i want to obtain its best from this hardaware, is my first time i've a Windows Phone 8 Terminal and i want every root right and attribute to installa whatever i want.
What is the correct procedure to do this ?
It's sim operator locked, so i've followed the link cellunlocker.net and i use my IMEI to unlock the phone. I'ts works.
After that I've downloaded this:
http://forum.xda-developers.com/showthread.php?t=2094384 <-- I dont know if that is a modifie rom, that allow to run alternative store or homebrew software, there is no tescription, but, i've tried to flash my phone whit this, but it return an error, somhting like an error with CID. What's wrong ?
I know, i'm a noob, and my procedure it's uncorrect, but, were i can find a guide with the correct flux diagram to obtain best by my phone hardawre ?
Tankyou for fast reply.

Hi, I'm not sure if you've already managed to unlock your phone but here's what I did to unlock my two HTC 8S' locked to Telstra (Australia).
It took me a little bit to find out if the online unlocker sites were legitimate. The first one I tried which was legit but didn't have a code for my 8S was HTCSimUnlock.com. They offer a full refund (which I'm still waiting for) if the code doesn't work or if one is not available in their system.
I then tried cellunlocker.net, again they offered a full refund if it didn't work so I gave it a go. Success! Within 10 minutes of my order I received an email with the 8 digit unlock code which I entered and could then use my Vodafone SIM.
The part that sucks is that the first 8S died after trying to install an update. I got it replaced and was had to pay for another unlock code. Anyway. I'm happy to say it can be done.
I'm in the process of uploading a video of me unlocking the 8S but if you have a look on Youtube for unlocking HTC phones, the process is the same.
Simply the process is:
1. Order an unlock code using the IEMI on the phone or box.
2. Put in SIM from a carrier you want to use.
3. Power it on, it will prompt you enter the unlock code.
4. Enter the unlock code.
5. That's it enjoy!
Good luck!

he want's to flash his phone not unlock it ( he already did that). I would like to know that also how to root my htc 8s

Not possible...yet :/

[Q] HTC One V Sim-Unlock Help

First post, need some helpful advice
I have a HTC One V on Virgin UK networkwhich I need to unlock. I purchased an unlock code online as after researching, came to the conclusion it (as of yet) cannot be done for free.
Anyways, I inserted the new sim card and turned on the phone but I dont get any pop up message asking me to enter the code. All guides I've read say that this should automatically pop up. I done a hard reset but that didn't help. The SIM is definately detected as I can look at the details in settings menu.
Any help would be greatly appreciated.

Are you on a custom rom? I think you have to be on stock to sim unlock a phone with a unlock code.

Not using a custom rom, phone is just out of the box

If I boot the phone without sim and then insert the new sim I get the following message;
"Unable to detect your SIM card. Please make sure that your SIM card is properly inserted and restart your phone."

After reading about it,
Does the phone accept your non-Virgin SIM? Do you get network access?
Not every phone is carrier locked.
You may also want to try disabling the HTC Fast Boot option. It does make start up, slower but it forces the it to actually shut everything down. It should be: Settings -> Power -> Fast Boot
Option A) Shut the phone down, after disabling 'Fast Boot', make sure the non-Virgin SIM is inserted, turn the phone on.
Option B) Hard Reset/Factory Recovery with the other carriers SIM inserted.

[Q] Can I use the phone in another country with S-ON?

Can I flash a different RUU ? Or is there any option ? I am going away and wouldn't want to sell my HOX

Yes, you can use your phone in another county with S-ON! However, your phone must be carrier unlocked (if it isn't)
Why do you want to run a RUU?? You want to go full stock?

If your phone is bought from a carrier, it is probably simlocked. This means it will only accept sim cards from that particular provider, and neither an RUU or S-OFF by themselves would change that. If you want to use a sim from another operator, you need to sim-unlock your phone and, currently, your only option is to obtain an unlock code from your provider or a third-party vendor. When you have the code, just insert the new sim card, it will prompt you to type the unlock code, and then you'll be able to use any sim you like.
