Question about Sim unlock - AT&T Samsung Galaxy S7 Questions & Answers

I got a Sim unlock code from at&t today for my GS7 however I'm not leaving for another carrier just yet. Does the code expire?
I'm not sure if I should just borrow a friend's Sim card, pop it in and unlock the device then just put my at&t Sim back in or just hang onto the code until I'm ready to use the phone on another carrier.
Thanks in advance for your thoughts and direction on this.

does not matter

Code
Thanks for the reply.. I got it from at&t.. Sent it within 48 hours of request

SIM unlock

I got my sim unlock code from t-mobile, I was wondering if there was a way to unlock it without inserting a foriegn sim card.
Not that I know of...I mean by foreign if your referring to a sim card from a different country yes...all you need is a sim card from ATT Cingular...borrow a friends sim card, and place it in when it asks for the subsidy lock or unlock code..put the code that tmobile gave to you...its as simple as that..then afterward place your simcard and now you have an unlocked wing!! Hope I helped you!!

I just requested my SIM unlock code for my Wing. About how long did it take you to get the code back from T-Mobile?
they should email it to you, right?
i guess it could take anywhere up to like a day or two. Try contacting them and asking them to resend it or something.
Tmo has an unlock team/sim team. Based on the east coast. They are swamped but if you can get in touch with them they will usually email you the codes for overseas travel after two days. Dont know the number.

[q] please help-atrix unlock issues

I am not sure what happened. I have an ATT branded atrix. I purchased an unlock code from someone on ebay, and the code was incorrect. I entered the code several times and I believe i have carrier locked the phone. Now even when i stick my att sim card in it brings up the "enter network unlock pin screen." I can hit dismiss and get into the phone but I cannot get service even with my att sim card in the phone. So as of right now my phone is not unlocked and is unable to be used with any sim card. Please help as i need the phone. any advice will be helpfull.​

[Q] AT&T S5 -- Sim question

Thanks in advance for your time.
I consider myself somewhat savvy. I have searched all over for an answer before asking:
I bought a SM-G870A and I have tried putting an H2O SIM card with no unlock screen. I tried two other SIMS with no unlock screen. I assumed it was unlocked.
I tried selling this phone to a guy who was going to use it in Mexico and told him it was not SIM locked. He tells me that when he puts his SIM card in it asks for an unlock code.
I am lost as to why it would suddenly ask him for an unlock code but all my SIMS did not. I have not been able to see him try in person yet.
Why would I be able to put SIMS in the phone and not get asked for an unlock code. I thought that meant it was unlocked?
Thanks for the help!
I just went through this "sorta" thing when I unlocked my t-mobile s5. I took out my t-mobile sim and put in a metropcs pcs sim and got no unlock screen upon reboot. I put in a cricket wireless sim and upon reboot I got the unlock screen, which I quickly put in my unlock code.
I'm assuming since metropcs is owned by t-mobile, that is why it didn't ask for an unlock code.
Is h20 owned by at&t, if so, that could be why the phone didn't ask for an unlock code when you put in the h20 sim

Thanks for the feedback. There could be something like that going on.
h20 uses the ATT network.
I tried a Simple Mobile (T-mobile) and no unlock code prompt
I tried a US Cellular LTE card -- would not connect to network -- no unlock code prompt
I tried a Verizon LTE card -- Same as US Cellular
I am stumped as to why this would happen. I would think a locked phone would not accept those cards without an unlock code prompt.

unlocking note 4 question

Hey guys just purchased a code from cellunlocker.net and was wondering can I still unlock the phone if I don't have a foreign sim card? Just switched to Verizon so I no longer have service in the ATT sim. Is there a way to manually bring up the screen where you input the code?

How to unlock my Nexus 6p? EE UK

Hi guys, I got my Nexus 6p last week from EE (UK network) and I have a problem:
Next week I'm going away to a diffrent country (Poland) for Christmas and New Years Eve and wanted to put a SIM card from that country into my phone, but it says I need a PUK code to do it... So I called EE and said what the issue was, and it turns out I will be able to get after I will have been for at least 6 months with EE ( I'm a new customer).
Is there any way I can unblock the phone on my own?
Cheers in advance.
If it requests a PUK code, you have to find the PUK code that belongs to that SIM card (from Poland).
So, you'll have to call Poland for the PUK code, or have to check the documentation you got with that SIM card.
I think EE was talking about a network unlock code, that's a complete different thing.
Edit: A PUK code is normally needed when you enter an incorrect PIN 3 times.

Yeah, you're right, I meant a network unlock code.
So is there a way I can unlock it on my own?
Anybody?
I used this http://m.sim-unlock.net/sim-lock/72/Unlock_by_code_for_Huawei_phones/#details worked a treat and I had the code within 24 hours
