Just making sure - root and unlocking without SIM card - G2 and Desire Z Q&A, Help & Troubleshooting

I'm purchasing a Desire Z on Friday and for some reason I started thinking about whether I need a SIM card in the phone or not to root + SIM unlock it. My carrier is Rogers and the phone will be from Bell, for which I have no active SIM card.
I'll be fine for doing everything necessary to get it to work with my Rogers SIM without one actually in it, right?

You cannot use that phone on rogers without sim unlock

That's what I'm saying, I'm going to unlock the phone. I just wanted to make sure I can do it without a SIM card IN the phone because the only active one I have is the one I need to unlock the phone to use.

To unlock it put in your rogers sim it'll ask you for the unlock code. If entered correctly you can use it with your rogers sim

Pretty sure you can unlock it without a SIM in. There is another recent thread from a guy using a G2 in the UK on O2, and it wouldn't pick up a signal until he ran gfree on it to unlock it properly.

[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?

If you are S-OFF (not rooted but S-OFF) then your phone is problably sim unlocked. Take into consideration that not all sim unlocked devices work with all carrier sims. Some carriers lock their sims so they can not work with unlocked devices.
If you used the Hack Kit to root your device, then you are simunlocked. Check it this way: http://forum.xda-developers.com/wiki/HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD

I used the Ace hack tool kit which rooted and S-OFF'd my device. Tried a Giffgaff sim and it never worked.

I just tried another one after purchasing an unlocking code and the SIM works. How retarded of me. So is it just some SIM cards that wont work or is it generally all sim cards from a specific carrier?

Seems that GIFFGAFF locks the sims...so you probably will have to ask them for a new one.
Yes.
Yes it can be unlocked but not free. You have to get your unlock code provided by your network service provider, for that you have to pay a little bucks. To get the unlock code you can go to Unlock-Zone.com and select your country and network to which your phone is locked. And get your unlock code through mail.If you try with free codes there are many possibilities for your phone to be hard locked.

If you downgrade to 2.2 you will regret it. If you are s-off Then you Sim unlocked. That doesn't mean that every Sim works with your device. Some carriers lock Sims...

I have a rooted Inspire 4G (rooted with Ach Hack kit). I recently purchased a T-mobile sim (0.99 cents) and put it in my phone and it worked. So I am thinking that when you root the phone with Ace Hack kit, it automatically removes carrier sim lock too. I don't find any other explanation for T-mobile Sim working on my mobile as I never unlocked my phone.

Yes AAHK SIM unlocks as part of the process.
i see.
i tried the sim unlock in the easy radio for dhd and even though the files were successfully pushed but i think my phone is still locked to carrier.
is ur unlocked phone still showing carrier brand when booting?
can u use the phone without sim card inserted?
Apart from checking if your phone is S-off, which my is. Is there another way to check to ensure phone is unlocked?

If you are S-OFF you are probably sim unlocked...however to make sure that you are, you can use this (paragraph 4)

unlock without sim card?

At&t gave me an unlock code so my note 2 can be used in China. I don't have a china sim card yet. It seems I need the sim to enter the code. Is it possible to unlock without a sim card using the code att gave me?
No just get one of your friends TMO SIM and that will prompt for the unlock code!!!

Any non att card should work. I had tried to unlock with older nonatt simthat I cut down to the micro sim size to unlock
Alternatively you can just use the hidden menu to unlock which does need the sim unlock code and other sim if I recall correctly

If the phone was properly unlocked in the first instance, it would be impossible to lock it back again as the unlocking process should survive any firmware upgrade. I'm somewhat puzzled by your question. Could you please clarify? The only way to test if it is still locked would be to put a non-standard SIM inside (i.e. any non AT&T sim). If it requests an unlock code, then it means it was not unlocked at first.
Yes I did this I put non-att Sim card and it requests an unlock code
Before flashing it was working 100% without att Sim but now NO

Were able to use the phone with another carrier's sim card? After fixing your phone, it will only work with an AT&T sim card?
Yes it like this
I am wondering from where could I get back the unlock code.
Any way any idea
Sent from my HUAWEI Y511-U30 using XDA Free mobile app
Did you buy a code? If you did, the unlock code would not have changed as long as the imei did not change.
If it was unlocked when you received the phone, you'll have to buy another unlock code.
I'm surprised it became locked after it was bricked. I didn't think this would happen.
Are there any firmware for unlocked sgh-i747.
Sent from my HUAWEI Y511-U30 using XDA Free mobile app
If you are on a stock ROM that is 4.3 or higher, you must buy a code.
