What to do with a sim unlock code? - General Questions and Answers

Im about to call metro pcs for a sim unlock code so that I can use a t-mobile sim on the phone (it's the old type metro phone) and I'm wondering where would even put this code?

Call the customer support team and discuss this with them. They will help you with good suggestion.

Change The Sim Card Or put a Different Sim Card and Punch the code if the Device Ask you

OK thanks

AT&T Subsidy Unlock directions

I bought the unlock code for my Fuze online. I do not have a non-AT&T sim and do not want to remove and re-insert my SIM.
Does anyone who's previously received an unlock code from AT&T provide me their instructions on how to apply the unlock code?
In my previous devices AT&T provide me a string of numbers/symbols plus the subsidy unlock code.
Thanks for the help.
the first step is to get the unlock code, easiest is to call them and tell them that you are travelling overseas and will need to use a local provider. you'll also need a sim card from another GSM provider, i don't think there is a way around this. you turn off the phone, then insert the other sim card, then start it, the phone will ask you to provide the unlock code.

I got my Fuze from AT&T before they made the mandatory 'data plan on ALL smartphones' went into effect. I bought my unlock code from eBay. I want to enter the code without having to use a non-AT&T sim card. From various boards it seems like taking the sim out, using a different sim, and then going back to the original sim would somehow tag the smartphone as needing the data plan. So bottom line is that I want to avoid AT&T's bullsh*t data requirements/policies.
On my Nokias I would enter a string of symbols with the unlock code on the dialpad and the phone is unlocked.
I wanted to get the instructions from Fuze users who called into AT&T and got the unlock code. What were the AT&T instructions? Would AT&T tell users to insert a non-AT&T sim just to unlock?
This board has been extremely helpful and I appreciate all the help.

AFAIK, the only reason you can need the unlock code, is to use such phone with another carrier, e.g. t-mobile, or overseas. don't see the relationship between the unlock code and att's new policy
anyway, i think you still have to find a sim card from another carrier to apply the unlock code.
Maybe there's a way to unlock the phone with the unlock code without using another sim card, but I've never heard of it. And what's the point, anyway? If you want to unlock the phone, you clearly want to use another sim card (and presumably have/will have one). I really doubt that unlocking that way is going to alert ATT that you don't have a data plan (how will they know when their sim isn't even in the phone??). You're going to put the other sim card in there sooner or later. This sounds like the type of crap that an ATT rep would say.
The only other way to unlock the phone is with Olipro's unlocker. That does not require another sim card, but it does flash/hack the phone.
Yes. I agree that the line you gave would be AT&T-ish. I'm on the fence right now about switching away from AT&T but have a decent deal via a family plan. I wanted to unlock my Fuze just in case that day came.
Just find someone who's on t-mobile, borrow their card, and get it over with. I unlocked my fuze (non-contract variety) the day I got it and have used it on t-mobile (cheapo pre-paid card) ever since. I also have an Orange UK card that I've used a couple times. ATT hasn't called me yet to tell me I need a data plan, lol.

How to enter subsidy unlock code on G2x without an unsupported sim?

Hello, I got an unlock code for my g2x through tmobile, and the instructions say to boot it up with a non-Tmobile sim inserted. Does anyone know how to get to unlock input screen without a non-Tmobile sim available? thank you for your time.
(I read some people advised to dial #073887* to bring up the screen,but no luck. I guess this is for att phone only?)
I can't remember off hand but a google search can find it, it is same process as the O2x. However when I tried to enter my unlock code with the T-Mobile SIM in it, it didn't work. I needed a non T-Mobile SIM for it to work.

Try this method
http://www.lg-phones.org/how-to-unlock-the-lg-optimus-gt540.html
it worked with my Optimus T and I am sure it will work with G2x as well (but I have to wait for a couple of months for free unlocked code from T-Mobile).
note:
you MUST input from dialer
2945#*999#
while #*999# is G2x model number (P999)
do have have to replace "540" to "999"? I think i just going to ask someone to let me an att simcard (All my family and friends are using tmobile/sprint....it's hard to get an att simcard for me....*sigh*)

Yes, you MUST use 999 instead of 540 because #*xxx# is your phone model.

how to unlock for international prepaid sim card

hey guys.. i brought my att skyrocket to seoul so i could use a prepaid sim card. my assistant got a sk telecom prepaid sim card for my phone and inserted in my phone and upon booting up, it's asking for the sim network pin code. the card that the sim card came with has a pin code and a puk code on it which none of it works. i've already chatted with at&t and they told me the code has nothing to do with at&t and the pin code is for the prepaid card ive put in. anyone know what i'm doing wrong? is it be possible that it's because its a weekend and that monday might start working?

[Q] How to unlocking sim card?

I wanna know how i can do this and im not sure if its unlocking or not
I want to use this phone on straight talk but the phone is meant for Boost Mobile. Is there any way of making it so that I can make it work for straight talk?
Motorola MOTO G XT1031
What im really asking is Do i have to unlock the sim card or unlock the phone itself?
You have to unlock the phone.
You can ask Boost Mobile support for the unlock code. If you say you need it to be unlocked so that you can use a different carrier's sim when you travel outside the country, carriers usually give the code to you as long as you have owned the phone for more than six months. Otherwise, you can google for sites where you can buy the unlock code. Once you have the code, you have to follow instructions specific to your Motorola Moto G to enter it in. I googled and found this:
How to enter the unlock code:
1. Power on your phone with a non-accepted SIM card. A non-accepted SIM card is a SIM from another network provider, other than the network you originally bought your phone from.
2. Wait for your phone to read: “Enter unlock/ subsidy code” or “SIM Network Unlock PIN”.
3. Enter the unlock code
4. Your phone will read: “Unlock Successful”.
Once unlocked, you will be able to use any sim with this phone.
Also, this is not the same as unlocking your bootloader so do not get confused while Googling
i thought the unlock was applied to the Sim card?
No the unlock is applied to a phone.
For example, if you take this sim card and use it with any unlocked phone it will still work. So the sim is not locked, the phone is.

Sim unlocked or not?

I've got a p40 pro (ELS-NX9) dual sim. I bought it off ebay reseller as sim unlocked and have used it on EE for over a year.
I am changing to the 3 network and their sim doesnt work - the phone asks for a sim unlock code. I rang EE and asked for a code to sim unlock, they said it would take a couple of days.
Today I got a message from them saying it is sim unlocked already.
Any ideas why the 3 sim doesnt work? Is there a way I can check?
I have both sims in the phone and tried them in opposite sides of the sim holder. The sim settings are fine. I have put google on it - would this make a difference? I dont want to go through the hassle of backing up everything again!!

”The SIM card unlock code, is the PIN number that came by default on your SIM card or the SIM card PIN that you set yourself. The purpose of having a SIM PIN is if someone found your SIM card they would not be able to make a call or access the info on it without first entering your SIM card PIN number”
Should be written on the SIM- big sim holder Card. ( default could be 1234 or 0000)

So why does my original EE sim work with no pin? The 3 sim is brand new and has no service, it arrived pre activated by 3, all I had to do is put it in the phone. I guess I should say network unlock instead of sim unlock?

A brand new sim come with the PIN written as on image, by default. You can remove it, change it, but first of all you need to provide the PIN code on the first connection to have access on it. It doesn't care if it has service or not.
It is better to try that SIM card in other phone. Maybe this other phone will provide you the same request.
Also you can ask a SIM (3 network) from a friend that for sure has the PIN inactive to see if it works on your phone.

Not in this case, the sim is pre-activated. It is a carrier code that is needed
I understand. It can be unlocked. I think it is not for free, but you will find solutions on-line or in service (not Huawei service).

SIM network unlock NCK
I have an 18 month old P40 Pro and currently have the above error when putting in the unlock code. I obly have 4 attempts left. Please help. Thanks Paul

According to EE the phone is unlocked, according to 3 it isn't blacklisted, waiting for a new sim now to try again.
Ifr it is locked, it will be the first P40 Pro locked that I have ever heard.
I've had a reply from Huawei, It was sold to EE locked to their network. According to EE it is unlocked lol! Back to EE I go I guess
