[Q] Using sim in another phone

Can a O2 sim work in a 3 phone. I received the phone from Three on contract. The phone is rooted but would i need to run some sort of program to hack the phone to enable other sims?
Cheers

AT&T On DI2

I'm trying to figure out how to get my rooted Droid Incredible 2 (with CM9 ROM) working with AT&T. I live in the U.S. and don't really care which band I use (Don't Need 4G). What are the steps I need to do to make it work, if possible?

You'd have to flash back to a stock rom then call Verizon and ask for an unlock code for your inc2 and just say that your letting a friend borrow it and there going out of country and it should take 1 to 3 days for them to email it to you, then insert your at&t sim card and a locked sim card message should pop up telling you to inter the unlock code then type in the code and bam your done

Yes, unlocked DI2 does work on dometic AT&T or T-Mobile sim card for voice/SMS and 2G/Edge for data access (plus WiFi, of course)
AFAIK, they do not email the unlock code - unless they changed the procedures lately ... If you are already on a custom Sense DI2 rom, you should be okay and have no need to flash/unroot back to stock Rom just to do this - photos attached were saved while running SkyRaider's Zeus rom and Nit's Sense v5.0 rom, both of them worked flawlessly on GSM bands using prepaid Sims. The last one was snapped inside Starbucks in old San Juan using WiFi as signal wasn't great inside in extended roaming.
As VZW customer in good standing & account balances paid up-to-date, call from a land/secondary line & speak to Global Support (smartphone) tech staff (leave the DI2 up & running, battery charged & a spare/working Sim card on hand) and explain your need, they will verify your identity and once done - proceed to help & walk you thru the steps to unlock the device immediately - take 10 to 15 minutes including hold time as they search & retrieve the unlock code in their database. Did this awhile ago, vacationing down in the Caribbeans and need to use local Sim for calling and they will "caution" you about not able to provide tech support and customer being fully responsible for charges incurred, etc. with a sales pitch about various global/roaming options, etc. ... (Urrrr .... okay, understood, but let's just go ahead & help get it unlocked ... allright, please hold while ...)
You will be instructed to power down & reboot the device, and input short codes to access the special/unlock menu and carefully input the unique code, hit "Enter" and watch for the screen display for a successful unlocking. Then, power cycle it and check/test it for a successful dialing with your own Sim card and be done with.

They told me they had to hand it off to there "global" department and it took them 2 days to email it to me.

So the recent laws against unlocking don't have an effect for existing customers? I'll raise hell if they refuse to hand over the unlock code before I move to Lesotho.
Also, if I understand everyone correctly, they only hand over the codes for customers who got the phone from verizon? What if I picked up a 2nd Inc2 on ebay? They wouldn't hand over the code?

[Q] SIM Unlock PIN

Hello,
I've bought an unlcoked Galaxy Nexus about 6 months ago, and everything worked perfectly.. until now.
Recently, I've had problems regarding the SIM Unlock PIN.
When I turn on my device, it requires a code.
I can choose to ignore that message and use my phone in any other way but using mobile network (can't text or call).
From what I understand, my phone has been locked to a specific network and I need to get the code to unlock it.
But I have no idea which network my phone is locked to..
Is there any way to find out?
Also, this has happend before, and I, who don't know what to do with it, took it to a guy who fixed it for me (He changed the Android version and did whatever he did.. I have no idea.)
Last night my phone ran out of battery, and today when I charged and opened it, it was locked again.
I don't know what caused it.
Is there any way to remove it permanently?
If not, can anyone help me remove it temporarily without paying too much money to websites I don't trust (Which require to know the network my phone is locked to, by the way...)?
My friend said that when the Android version changes, so does the code.
My currently Android version is 4.1.1 and I can choose to update it. Would it help?
Thank you, to whoever is willing to try and help me.

Is your phone have a GSM sim card??

Yes, I do.

Help anyone..?

[Q] how to SIM unlock a T-Mobile G3?

Hi,
I just purchased a used T-Mobile G3 that I will be using on AT&T. Does anyone have any pointers on how to SIM unlock it? Is there a preferred method, or preferred supplied on eBay for unlock codes?
Thanks,
Toby.

OK, so I bought a code there, and 5 hours later is still hasn't arrived. So I bought a code from these guys: http://www.imei-unlocker.com/ which did come through. However, there are no instructions, so I found some on YouTube for the G3, https://www.youtube.com/watch?v=8TFWgPX5Al8
The trouble is, when I put in my AT&T SIM card into this T-Mobile phone and start it up, I am not prompted to unlock the phone at all. It starts right into Android and behaves like an unlocked phone except it says the network is locked when I try to make a call. That's it. No indication anywhere of how to access the unlocking mode. I'm stuck.
Edit: I found these instructions on T-Mobile's website, which confirm the method in the video:
http://support.t-mobile.com/docs/DOC-11974
Edit #2: about half hour after I wrote this the unlock code came through from the first site. I still no idea how to get past not being prompted to unlock, though.
Thanks,
Toby.

OK, resolved, if it helps anyone.
I managed to find an alternative method somewhere else that doesn't rely on an alien SIM card prompting an unlock code.
So the code from unlockcode247.com did eventually arrive, but without any instructions. A couple of hours after ordering it I gave up and bought a code from somewhere else. The email with that code took about 20 hours (!) to arrive, despite their page saying it would take a maximum of 2 hours. Bah! At least it contained a range of instructions on different methods to unlock in addition to the basic one of putting in an alien SIM. Someone might find these useful:
Method #1 Go to the dial screen and press “2945#*model number#”
for example if its a p999 you enter “2945#*999#” or if its a p990 you enter “2945#*990#” etc…
[so that's 851 for my T-Mobile phone.]
Method #2 to the dial screen and press 2945#*71001# as if making a call, enter code when prompted
Method #3 Go to the dial screen and press *#865625# as if making a call, enter code when prompted

I do find it strange that the phone didn't react to an alien SIM, but oh well, it's great that there's another way around it. All unlocked fine now.

do not use imei-unlocker
I ordered 2 days ago from imei-unlocker but no response, i have sent them various emails but no response.

On the website It says delay for lg services. Maybe thats why?

Since this was a used phone it is possible that someone tried and failed unlocking it more than the maximum allowed tries.
I know whenever I have unlocked a phone, the prompt to unlock warns that you have x number of tries (I do not remember that number).
Also, I do not know if there is a way around it.

As long as you don't have any debt to T-Mobile don't they need to have a free solution to unlock your phone? For example if I called them right now they would unlock me for free even though I still have debt because I have had the phone for 6+ months. People got it unlocked through T-Mobile days after buying the phone by just saying they were going abroad.

I believe he has his unlock code. The problem is that when he boots up the phone with a different carrier's sim in it, it is not prompting him to enter an unlock code as it should.
Looking at my unlock instructions, I proposed the posibbility that someone tried and failed 10 times or more. Just guessing:
Read This First
* DO NOT use all attempts to enter the unlock code otherwise your phone will be hardlocked (all phones have at least 10 attempts)
* Make sure "Airplane Mode" and "Wi-Fi" is turned off under wireless connections if your LG is an Android device.
It also has other methods for trying. Perhaps another method will work:
Method #1 Insert a non accepted simcard, and enter code when prompted for a code
OR
Method #2 Go to the dial screen and press “2945#*model number#”
for example if its a p999 you enter “2945#*999#” or if its a p990 you enter “2945#*990#” etc…
OR
Method #3 to the dial screen and press 2945#*71001# as if making a call, enter code when prompted
OR
Method #4 Go to the dial screen and press *#865625# as if making a call, enter code when prompted

Quick question.... I just got my unlock code from Tmo. I was wondering if the unlock is retained no matter how much somebody may root/unroot/change ROMs/etc. Is it a "forever" thing? Or just for the current setup? Oh and do I unlock with Tmo SIM in or with the ATT one?

*Edit* oops replied to the op, disregard this post.
