[Q] [q] d2g + us att sim?

So I've done a large amount of searching, not only on XDA but elsewhere to find a real 'answer' to my question, but I haven't found anything concrete, hence this thread.
I have aquired a Droid 2 Global from VZW for free, and I want to use it with my US ATT SIM, on the US ATT GSM Network.
Things i have done:
- Flashed the phone to the stock OS in order to....
- Flash the radio so it accepts ATT GSM signal
- Aquired the sim unlock code from ATT for my current phone/sim (I'm unclear on exactly what this whole sim unlock process is about, perhaps why I'm asking)
The phone boots, but when I have my SIM inserted, it asks for the unlock code.... What exactly IS it asking for?
The SIM unlock that I recieved from ATT doesn't work.. (I assume this is the unlock for my sim, in my current phone?)
What is the next step, if this is possible? I've looked at getting the phone unlock code via ebay, or one of the piggyback devices like TurboSIM, but I'm unsure what will work, if anything will work?
Help??
Thanks in advance for any info provided

It asks for the unlock code you can get from VZW's Global Support if you are a VZW customer.

Well, since I'm at ATT customer, how would I go about getting this code? I do have a friend that works for VZW, which is how i got the phone, and he is willing to assist me. Can he provide it?

The phone must be on an active line of service, and the billing history must be clean for the past 6 months.
If your friend works for Global Support, then maybe. If not, I doubt it.

Hmph..
I guess I overestimated the difficulty of getting this to work. It was just another case of having to get the unlock code from the phone itself via IMEI number,and yahtzee, working as I had hoped.
For some reason I had the notion that it was significantly more difficult after reading all of the posts about trying to get other SIMs to work.. but its actually very very straight forward and easy.. it just seemed that nobody had ever really made it clear that a US ATT sim could work on a VZW D2G handset with US ATT service.
Thanks for your input!

Help: Can not unlock SIMLOCK TMobile Z3

I have TMobile Z3 with SIMLOCK. But when insert international sim, the phone did not pop up table to insert the code.
I also have DeviceUnlock app on my phone but it did not work as showed at clip.
Please help to advise me this case.

Need a t-mobile sim to permanently sim unlock it. Did you pay full price for phone? Or are you on contract still?

First of all please hide your IMEI Number from Picture by paint on it
It easy that some people can use this IMEI for their own benefits. which is not good

Already test with TMobile sim but it dod not work. I bought phone and unlock cofe separately.

You can't, it needs to be done over the air, for me they unlocked it when I called, as the app did not work. They will only unlock it if you are a customer. That too after 40 days of service using the device. Only option for you is to give it to a TMO customer for use temporarily.

After searching on google, I found instruction as below:
- unlock bootloader
- root it
- push simunlockapp.apk to internal memory and restart, it will pop up table for unlock code.
But now I stuck at bootloader...

Network unlocking

My Sprint variant arrives tomorrow and I'll need to network unlock it to use with my carrier (wanted the unlocked bootloader).
Am I going to have to go on say eBay and do the IMEI method or will the first sim inserted feature work?
If the IMEI way, are there 3rd parties currently that support the S7?
note: I don't know how generating the code works so I don't know if it's model dependent when generating it.
EDIT: Can confirm first sim inserted does not work. Prompted with "Invalid SIM card" with an AT&T sim in Sprint variant.

I can tell you, as far as I know no one has tried the 1st Sim inserted locks to that network theory...I hope you give it a shot, as it could confirm or deny this theory.
Sprint has unlocked bootloaders?
Good questions btw, I'd like answers to these questions as well

I was surprised too. I asked a rep before purchasing and they said they did; as well as a couple others stating it. But rather that's true or not, I'll find out soon enough

I can confirm that the AT&T s7 was sim unlocked. Bought outright at Bestbuy and picked up tonight, I put my cricket sim in and it worked perfectly. I can not verify if it is locked to cricket or not since I don't have another carrier sim to try. I received no notifications that I had a cricket sim or anything it just worked.

Cricket works on all? AT&T phones because Cricket uses the AT&T network. I have an AT&T S5 using cricket with no changes needed but APN settings. I'll confirm tomorrow, unless someone else does before hand, if the first sim feature works with a Sprint variant.

Unless I'm mistaken even on AT&T phones you still had to unlock then to us a cricket Sim

I didn't with my S5, unless something changed.

The OEM unlock option is in the developer options of the att s7. I only have an att sim though, so i can't test it. I didn't buy mine outright.

Cricket Sims work on AT&T SIM locked phones.

Same for T-Mobile. There is also a "Device Unlock" app in the T-Mobile folder/

I will try a different sim today...
My phone arrives later this week - no next day shipping for me I guess I will try my Vodafone SIM first when it arrives and see what happens.
Will post the results if no one beats me to it.

FYI... The OEM unlock option in developer options has absolutely nothing to do with Sim unlock.

it begins the process of allowing you to unlock your bootloader, if your bootloader is unlockable.

Ah ha

The reason its because of this phonearena dot com/news/Certain-versions-of-the-Galaxy-S7Galaxy-S7-edge-lock-to-the-carrier-of-the-first-SIM-inserted_id78809

Since you bought the phone outright, can you still get on the GearVR promotion bandwagon?
I am on the ATT Prepaid (GoPhone) plan and don't want to change over to post-paid. But I was told I can't actually pre-order and still retain my plans with GoPhone.

Hey TehPirate_,
Unfortunately the Sprint S7 and S7 edge can't be unlocked by code
you can however contact sprint to request the to unlock it
The other GSM networks can all be unlocked by code such as AT&T, MetroPCS, T-Mobile(by Unlock app confirmed unlocked today Rogers, Fido, Telus, Bell, Vodafone, etc

SIM unlock S+

Hi,
Looking in this forum but can't see how to SIM unlock my S+. Phone was locked so I re-flashed with Odin but can't find guide to unlock SIM.
Phone is locked to UK Vodafone.
Can you send me please guide if there is some? Thanks

What is the message your phone displays when you insert a SIM card other than Vodafone UK (ie, a non-accepted SIM card) and try to place a phone call?
If the phone is locked, it will ask you for unlocking codes.

Yes, it's asking for unlock code. I could fix this with odin and some flash on my S7 Edge but how can I do this on S8+?

As far as I know you should buy the unlock code on eBay. Actually it depends on operator (each operator has its own way to lock it). For example Verizon doesn't lock GSM part on the modem for their phones at all. Sometimes remote unlock procedure is required (you will pay to third party and they will do it through the Teamview). The price depends on operator. There are 99% that you will not do it for free by yourself.
There is one chance to do it yourself only if your provider made some calling time lock. For example you have to insert Vodafone SIM card and make a phone call for some 5-10 minutes (but it shlould be done inside the country of phone's origin, UK in your case). Try to ask someone with a same Vodafone UK phone.
You can do it with Odin only if it was not really locked from the beginning but just had some carriers bloat, that was asking for that unlock.
What is exact model of your S8+? What does it says in Bootloader mode?

But actually I could do this with S7 edge. So S8 has some protection?

Was it the same Vodafone UK? What is exact model number of your S8+? What was original firmware and firmware you have feflashed with?

Based on other operators experience I would say you cannot do it by yourself as usually simple flashing will not unlock the phone. You will really need one of paid methods to unlock it. It is still better to ask someone with a same Vodafone phone. As unlockers on ebay etc. make money with those methods I don't really believe that someone here will tell you how to do that by your own.
There was a thread where the guy was discussing unlock for his Austrian locked phone. Finally he paid twice as first seller sold him some wrong unlock code and phone became network blocked completely. However he bought some "unfreeze" code from different seller and that worked for him. If it would be so easy to unlock operators phones they will never sell them cheaper than unlocked.
Another option is still to perform call with original Verizon UK SIM card for 10 minutes. After that you should reboot your phone and it should be unlocked. If it will not work you can approach Vodafone UK and ask them for unlock code. If there was no any financial issues for that phone and it is registered more than 6 months in the network they should provide you with unlock code for free.
Sorry if I didn't help you too much.

Sprint Galaxy s8 sim unlock

Hey there, I want to sim unlock this Gs8 I got from Sprint, Model: Sm-G950U , Software version: G950USQS2BQL1, I received an unlock code but was not able to input the code because it just said sim error contact sprint immediately, Unlocking by sprint isn't a choice as they extorted money out of me, I really want my galaxy s8 to be in service again any Idea where to start? Any help will be much appreciated , I come from a background of good software knowledge so other approaches are good too.

Sprint extorted money out of you?
Extortion is illegal in this country...

Does your phone asks for codes or not?
If it doesn't ask for code you can try the following 3 methods, however, they are not 100% guarantee to work:
Method #1: Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.
Method #2: Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE#
Method #3: Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE#
If none of these work, also check if your phone's IMEI is clean and not reported or blacklisted by Sprint.

Sprint phones are usually unlocked one of two ways and neither has anything to do with a code. One is via Sprint with an OTA thing. The other is via root + a 3rd party tool like z3x, Octopus, or something similar.

Hi! I live in Ukraine and I am thinking about buying sprint S8 bad esn on Ebay. Will it work internationally (in Ukraine)? Do I have to unlock it to use internationally? I had many Verizon bad esn phones and all of them work perfectly.

Need to SIM unlock Sprint galaxy s8 (also fear it may be "black listed" unpaid lease)
I bought the phone from someone and thought it would work but I was trusting instead of smart.. Should've checked it out first. Anyways im negative a couple hundred $$ and I would love if some one would be able to help guide me through unlocking the SIM and if necessary rooting etc. To make it work for my Metro PCS account. In short I need to be able to I assume "SIM unlock" my S8 and hope it'll just be ready to pop my metro SIM into it and it works. Any advice? Will it work if I can just unlock it and use my metro SIM? Or since its an the lease hadnt been fully paid will that be a problem... Ive checked on a couple sites that let you see the IMEI number and if its black listed but it isn't... Please help.

Correct. It IS an advertisement - and not a very good one. He obviously has no knowledge of phones whatsoever if he thinks that Sprint devices use codes

I too have a Sprint phone which I wanted to unlock with the help of information here on the site. Since you won't be able to use unlock codes, and also bcause when I called Sprint they wouldn't help me -told me to contact the seller of the phone to have it unlocked, I was desperate for any unlocking method. Hard to find a working one and didn't want to waste too much time (old Galaxy S5 was already at it's last breath) I made contact with one of the unlockers here on XDA and one was able to unlock it remotely for me. I did pay $15 but with the crappy internet I have and since most unlocking sites are asking $39 for unlocking S8 then I really didn't mind this $15. Took well over a few hours to do since I had to download combination file for my phone which took a while. It's unlocked now thanx to vosi7en here at xda. I do have 1 problem now and that's tethering.....I don't have the option to do any hotspots. Anyone have an idea? I can't root yet cuz I'm on latest Oreo now.

I'm not sure what a "tmobile for vzw sim" is. But you might need to remove the Sprint bloatware in order for it to work properly
