Bought it off of craigslist. Whenever I put my sim in it says it needs a code to unlock the sim or can only be used with a specific sim card...
Tried going to the store and calling att and samsung.. no luck. Anyone able to help with this?
I'm going to ask it. Are you sure it's an i637 and are you on AT&T? If so, keep calling until you get the right tech at AT&T. You probably just need the P-U-K code.
I called them up and all they gave me was an unlock code <_<

Hey guys, I'm new to the G1. I just picked a used one up the other day to use over seas. I reset the phone not knowing I need a SIM in there to actually use it. I don't have access to a SIM card currently, but I will have one when I go over seas. Will the phone unlock so I can root it with a SIM card from a different carrier? Or do I need to have a TMobile one in there? My plan leaves tomorrow early morning, so I'm kind of in a bind when it comes to solving my phone issues.

Oops, I thought I posted in General.
The sim card from n e where will work for the rooting process so don't stress that. These instructions will get u n to the phone with out the sim card. http://theunlockr.com/2010/01/10/how-to-activate-the-g1-without-a-data-plan-or-sim-card/

If the phone is locked , you need to get it unlocked first....otherwise it wont use any other network sim other than t-mobile.
The easiest way to unlock it is to call t-mobile and ask them for unlock code by giving them IMEI number of the phone (can be found in the MENU--->SETTINGS---->ABOUT PHONE----->IMEI NUMBER)
They provide the unlock code for free.
Once you have it unlocked, then whatever sim you insert, you will be asked to enter the unlock code. Enter that code and phone will start using that sim.
If you dont get it unlocked here from T-mobile then get it unlocked from the country where you are going...but the charges and success rate of unlocking depends on which country you are going to.....it is very easy and cheap in South Asia like India and Pakistan.....but difficult in Middle East.....
So the best alternative might be to buy a cheap GSM phone there and sell it when you return here.
Have a happy and safe journey
Thanks for the help everyone. Unfortunately, Tmobile couldn't give me an unlock code since I'm not their customer. I've got some more digging to do. I came across some sites offering the code for a fee, are they legit? I just don't understand how they get the code when I can't.
Go to ebay and buy it. for abt $6.49, they will give the code to you. I unlocked mine via ebay... Try any seller.
Based on timezone, buy from US seller or your local seller to get it quick.
Like for US try http://cgi.ebay.com/UNLOCK-CODE-T-M...025?pt=LH_DefaultDomain_0&hash=item1e5f205f99
Make sure u provide them your IMEI code.. dial *#06# Or look under battery.
I got a free Samsung Focus today, thanks to the Microsoft giveaway for TechEd, where the first 50 from TechEd who publish get a free phone. I was told that the phone was carrier unlocked... But since I'm on Verizon, I can't use it anyway. I am probably going to sell it on ebay (although I'm considering loaning it to a couple iPhone friends for a bit, so they can get the full WP7 experience), but I want to make sure it is unlocked before I advertise it as unlocked. How do I know for sure?
Also, if I do loan it out to friends, can an ATT (or T-Mobile since it is supposedly unlocked) customer just pull out their SIM and put it in here, and go with it? Or is there something their carrier needs to do?
Thanks!

Correct, you just put in a SIM card and use it. No carrier attention needed. To test if it is unlocked, you need to find a T-Mobile SIM card, or any other non-AT&T SIM card, and put it in. If it is locked, the phone will let you know immediately and you won't be able to use the phone or cell data.
Thanks. I'll have to have one of my iPhone friends try it for me. I don't know if anyone around here is on T-Mobile.
you can usually just go to tmobile and ask for one, sometimes they'll give one to you. and it doesn't have to be activated.
I read on this forum that the at&t sim card from straight talk would work for my unlocked phone only to find out that it wouldn't and now my number is ported to straight talk and I have no phone to use it for. I went to at&t store today and they plugged in my sim card and it asked for 17 digit number i think and he said it wouldn't work and I was just googling it and it seems like unlocking a cheap phone from the at&t store would work. This is very frustrating for me because I can't just call at&t and ask what there cheapest phone is and google it to see if it can be unlocked and will work because I have no phone and I also can't go to the store and simply google the phone product number to see if will work because I have no phone. any help would be greatly appreciated.
I really need help I'm very stressed out can someone help me? is there a store I can buy a phone from that will work?
What kind of phone did you put the Sim card in? Maybe you put the AT&T Sim into a phone that only uses T-Mobile bands.

Hello XDA-Developers,
I am at my wits end. I can not for the life of me find a Sim Unlock code for my Samsung Note 3 N900W8.
I will start from the beginning... I purchased this phone from a woman who is the manager of a telecommunications in London ON. She listed the phone on Kijiji as "Brand new in box, unlocked!". I met her at a kiosk for my carrier to test the phone on one of their sim cards. It turned out the phone was sim locked. She seemed nice enough and genuinely surprised when it came up sim locked. She said she had received the phone as a promotional gift from her company, but didn't like the size of it and wanted to use her existing phone. She asked me if I would prefer to have her get it unlocked or she would take 50$ off of our originally agreed price to put towards the unlocking cost. I opted to get it unlocked myself, my mistake lol.
First I had to find out which carrier it was locked to so through a process of elimination I figured out it was locked to Bell. I contacted Bell and asked to get a sim unlock code from them. They said that they have no record of my phone in any of their data bases and that I should contact Samsung and confirm that my phone is locked to Bell. I contacted Samsung who confirmed that my phone is locked to Bell. I contacted Bell again and they put me through to tech support. He was a nice guy, but didn't give me the answer I wanted lol. He said that because my IMEI is not in any of their data bases that there's no way for him to give me a code. He suggested flashing a different kernel and it would remove the sim lock? I'm sorry I am not that knowledgeable when it comes to this stuff. Anyways, I have taken the phone to 3 reputable phone repare shops in my area and tried cellun******.net. All have said that they can't find an unlock code?
You guys are my last resort, any and all help is greatly appreciated.
Thank You!
Hello,
I owned a Verizon Galaxy Note 20 Ultra that I bought shortly after release. I got bored with it, as often happens, so I paid it off in full and sold it, to someone who uses T-Mobile. They cannot activate the phone, when they put their T-Mobile SIM in it, it gives the message "SIM card is not from Verizon Wireless". The facts:
I owned and used the phone for well over the 60 day automatic unlock period.
It was active on my Verizon account for the entire time until a week before I sold it.
It was paid off IN FULL, and my account said the line was paid in full and ready for an upgrade.
My Verizon account is never behind or not paid on time (Auto-Pay)
Is there something I needed to do to the phone besides factory reset it? Is there anything that can be done? Should I call Verizon customer service? To further complicate matters, the person I sold it to lives in another state. I may need to have them send me the phone back and refund them their money if I can't figure this out.
Thank you so much for any help that can be provided.
Are you sure you used the device for 60 days?

Are you sure you used the device for 60 days? Did you check with another carrier sim before you sold the device?
SIM card is not from Verizon Wireless is a common message for all Verizon branded phones. May be buyer is confused with this message.

Thanks for your reply.
Yes, it was activated in late August 2020 and was active up until the end of December 2020. No, I didn't realize I should try a different carrier's SIM first.
I asked them if they are able to call or text despite the SIM card message and they said no.
You need(ed) to request VZW to carrier (SIM) unlock the device prior to selling it.

I'm so confused, Verizon says devices are automatically unlocked in their policies listed here: https://www.verizon.com/support/device-unlocking-policy/
I'm going to call Verizon, and see if there's anything they can do.
Update: Called Verizon tech support, and the agent confirmed that the device IS unlocked. He said I should have the buyer contact T-Mobile customer service and add the device to their database. Hopefully that works.

Adding to database is a Verizon thing, Tmobile is gsm. There is no way to sim unlock it if you don't do it on your phone line and request the unlock as if you're using the phone yourself.
Verizon will not unlock it unless it's currently on the line and met the other criteria you already have. For some reason verizon can't read if its really unlocked unless it's on their network, I went through it with an iphone earlier this year. They're a mess.
damn, i thought me getting a new phone annually is bad. you get a new phone every quarter? lol, actually i was thinking about trading mine for a fold 2 but no s-pen, no exp storage and a step down camera array, i decided to keep my note and see if they fix the fold 2's shortcomings.
what's in your pocket now?
It is quite possible that the buyer was not using an existing active sim. He was probably trying to activate a new sim which failed. I had the same issue with AT&T when activating a new sim. AT&T was not recognizing Unlocked model imei and I had to use a very old phone imei for activating sim after which I was able to use the same sim with with AT&T.
It also possible the buyer is lying to you. Either way it looks like the deal is going tits up for you. Perhaps next time check with a T-Mobile SIM before selling it or sell it as verizon locked. Feel for you.
Hello, i know this is a old thread but did you find the solution? i bought a verizon note 20 ultra and it doesnt work on any carrier, just work for a minute and it stops.
You guys found a way to unlock this? I just got the same phone and its a very expensive paperweight atm
