sim unlock of AT&T in the middleaset

simple question, i have a friend in the US, he is about to get an AT&T contract, and he doesnt need a new phone, if i make him buy me a samsung galaxy s 3, would i be able to sim unlock it to work on networks in the middleast, like Jordan, Saudi Arabia, Israel?
if yes, how can i do that?

Yes you can get an AT&T GS3 unlocked (Just unlocked mine today), If your friend is an existing member of AT&T and in good standing he just needs to ask for the unlock code. I just used the online chat support and told them I was traveling to Europe for a few months and needed my phone unlocked. They needed my IMEI and they gave me the unlock code. The whole process only took 10 min or so. Then I went to a T-Mobile store and ask to borrow a SIM so I could enter the code (You need to put in a non-AT&T SIM card for it to ask you for the unlock code)
Now the question is will the phone work for your network. For that you need to know if it uses the same network bands. Here are the bands that the AT&T GS3 supports: GSM Quad-band: 850/900/1800/1900MHz; UMTS Tri-band: 850/1900/2100MHz; LTE Dual-Band: Band 4/17
Is your networks use them then most likely it will work but the only way to know for sure is to find someone who has used an AT&T GS3 on your respective networks.

thanks a lot, that was very helpful, but my friend is not an existing member of AT&T, he will get a contract soon though, dont know if they will give it to him. any other way to get the unlock code if they would refuse to give it to him?

There are places that sell the unlock codes for a small fee (around $30 I think). I don't know how well they work as I have never used these services.

It is better than the Transformer Prime I had but still has some issues. The screen is really nice though. In the end mine is going back as I have the new Galaxy Note 10.1 coming tomorrow. The S-Pen is a killer feature for me, I'm a student and being able to take handwritten notes on it trumps the Transformer's superior resolution.
I don't know if it can replace a laptop as I never got the laptop dock for it.

[Q] OE1 Update / Odin Back

So I have read alot about how to downgrade from 5.0.X to lower versions of android to4.4.2 and 4.4.4 just isnt possible. Well, I made it happen tonight. It took 3 days to figure it out and I will gladly share how i accomplished this, and upload all the files. I didnt mess with the boot loader because frankly, I dont know how. Everything was done through ODIN as well.
But I am in need of help/ questions answered first.
My phone is 100% paid off, and I am 100% paid in full with sprint so it was my understanding as of FEB of this year upon request they HAD to SIM unlock my phone per my request... So here are my questions
1 - If i flash AT&T roms, or any other carrier ROM over to my sprint note 4, will my phone still function properly? And if it will, does that give me a better shot at getting the phone away from INVALID SIM error and putting in my MSL code.
2- is it really NOT possible to domestic unlock a phone from sprint with android L? if not, why would sprint tell me they could domestic unlock my phone?
3- I have been given my MSL, been told by sprint my phone is unlocked, and cannot get a prompt to enter the MSL so I can keep my note4 when i move to a new carrier. All I keep seeing when i put the SIM card into my note 4 is "INVALID SIM" , I have seen the SSU unlock APK and tried to use it but the lowest version of android i can find is 4.4.4 for the note 4, and SSU states it only works on 4.4.2 and lower.
Can anyone help me get this stupid thing domestic unlocked?

OK here is the issue if I understand correctly.
You want to unlock your phone Sprint has provided you the unlock code.....
Since the Phone was shipped with 4.42 or 4.44 depending when you go it ........ that means you will need to be in that Android version for it to work not running lollipop(5.x)..... Then :
Switch off your Galaxy Note 4.
Take out its battery.
Pull the Sprint SIM card out of the slot.
Insert a new SIM from a different wireless carrier in the SIM slot.
Place the battery back in the mobile.
Power on the phone.
When prompted, type the unlock code that you received from Sprint.
It will complete and you are done

Sprint's policy for DSU (Domestic SIM unlock) is phones *launched* after Feb 2015 will be eligible. Unfortunately, as the Note 4 launched last year, it is not eligible for DSU. The MSL code allows you to edit the APNs to go to another CDMA carrier., but will not unlock the SIM slot for domestic use.
Sorry.

Sprint will unlock a device from Sprint's network under the following circumstances:
Any associated Service Agreement, Installment Billing Agreement, or Lease Agreement has been fulfilled including payment in full of any applicable early termination fees or end-of-lease purchase options
The associated account is in good standing
The device has not been reported as lost or stolen, associated with fraudulent activity, or otherwise flagged as ineligible to be unlocked
Generally, if you have a device that was launched prior to February 2015 and it is capable of being unlocked, Sprint will provide a bill notification and/or text message when you are eligible to have your device unlocked. The bill notification will direct you to Sprint Customer Care who can assist in efforts to unlock your device.
For domestic SIM unlockable ("DSU") devices launched after February 2015, Sprint will automatically unlock the device when it becomes eligible.
For inactive devices, customers must contact Sprint Customer Care to request that their DSU-capable device be unlocked and may have to take steps to perform an over-the-air update to ensure the unlock programming has been relayed to the device.
The note 4 is capable of being unlocked. Sprints policy is they AUTOMATICALLY unlock them if it was launched after FEB 2015.

Now, can you tell us how to Odin backwards from OE1?
thanks

Can't I'd back wait til oe3 is out I made the mistake and paid the price

Sorry to burst your bubble but you're wrong. Note 4 is clearly on their list of phones they will give you the MSL or the ISU (International SIM unlock), but not DSU. Read for yourself: http://www.sprint.com/legal/unlocking_policy.html
Moving on in 3 - 2 - 1.....

Just swap for tmobile or Verizon note 4 ..post an ad. Meet at the store. Verizon is unlocked out of box. It will work on all but sprint. Tmobile will work and I believe Att with Sim unlock but don't quote me. Just an idea.

Verizon SIM in CARRIER UNLOCKED T-Mobile s8+ not working

Hi
I have a carrier unlocked T-Mobile s8+ and need to use a Verizon SIM in it and am getting errors trying to use a verizon SIM. The Verizon SIM is from another phone and is already registered. I put the IMEI number of the phone into Verizons web portal to test compatibility and it failed. Does that mean there is no way to get this combination to work? Does the IMEI need to be in the VZW database for this to work? Will flashing XAA guarantee this to work? Thanks for any help and advice.

do u have a tmobile phone, it is different than the carrier unlocked phone, those are 2 different models,
the carrier unlocked.. the sim is unlocked..
the tmobile is not carrier unlocked, and by flashing the firmware of the unlocked version, will NOT unlock the sim.. u will need to device unlock app with the tmobile phone 1st... and usually tmobile will NOT unlock unless u have paid it off and using on their system for 40 days..
others like me had it unlocked with days of service, cause we are tmobile customers for years already... I on the other hand bought the phone on ebay from someone who bought it from Samsung and the imei was not added to tmobile system and I had to call tmobile to add the imei which took about 3 days, then to call back to request the sim unlock which took another 3 days, the device unlock app unlocked the phone instantly...
that was my process for me to get the sim unlock... but if urs it not unlocked and is paid off, another way to get it unlocked it to give it to someone u know, let them use it and call tmobile to start the above process...
Hope that sums up what must be done...

Hi thanks for the explanation, I am pretty familiar with the differences between carrier (SIM) unlock and unlocked firmware as I have flashed Android in the past. I had the phone carrier (SIM) unlocked by T-Mobile through their app and I was still not able to use the Verizon SIM in my phone (not registered error). It turns out (and I found this out by reading through the many messages in this forum) that T-Mobile firmware apparently disables some frequencies that other carriers may use. Once I flashed the XAA unlocked *firmware*, I popped in my Verizon SIM and it worked like a charm. I hope this info is useful to someone at some time and I thank all of you for your contributions to getting this working. KUDOS!

Good to know, but sound weird, thought T-Mobile phones work for all gsm Sims just needing to change apn,
But now cdma merging with gsm, that's so much better as far as phones go, use any phone now from any provider.
Look how the s8 plus is all the same software and the same hardware, just different carrier stuff..

I thought it was weird too. Busted my head for a couple of days trying to figure it out. Is Verizon still CDMA? *scratches head*

Yes, their 3g and 2g networks are CDMA.

If you insert Verizon sim into T-mobile phone, you'll get LTE data, but you won't be able to make calls. Only data will work. T-mobile firmware support band 2, 4 and 13, so you should have data, but not phone service. If you don't have data icon, you'll need add Verizon apn.

FYI
Flashing the phone with G955U1 firmware fixed this issue. I am now able to use this successfully on Verizon.

Samsung Galaxy S9/S9+ Sim Unlock Code

I want to pre-order samsung galaxy s9 and s9 plus for me and for my son. the both phones will be from t-mobile and I have a question. can I unlock them the same day for at&t ? we have a great at&t plan with cheap family calls so I want to use at&t instead t-mobile. I heard that some newest models are hard locked so want to make sure before ordering. thanks

It depends on the plan you get from T-Mobile. There is are two things you need to do before trying to unlock it. Once you get your phone check the following:
1. Check your T-Mobile folders if there is the Device Unlock App installed (by default it should be installed on your phone).
2. Check your phone's IMEI in the T-Mobile database by using their service here: https://www.t-mobile.com/verifyIMEI.aspx
If your phones have the app and are not blocked it means that they are eligible, so you should be able to unlock them and even use a service like here: https://www.unlockunit.com/unlock-samsung-galaxy-s9-062472

hi, what is the difference between SM-G9650, SM-G965S, SM-G965K, SM-G965L, SM-G9658, SM-G9659, SM-G965U, SM-G965W, SM-G965P, SM-G965T, SM-G965V, SM-G965A, SM-G9600, SM-G960S, SM-G960K, SM-G960L, SM-G9608, SM-G9609, SM-G960U, SM-G960W, SM-G960P, SM-G960T, SM-G960V, SM-G960A, SM-G965F, SM-G960F, SM-G965FD, SM-G960FD, SM-G965N, SM-G960N, SM-G960R, SM-G960R4, SM-G960R6, SM-G960R7, SM-G960T1, SM-G960W8, SM-G965AZ, SM-G965D, SM-G965J, SM-G965L, SM-G965K, SM-G965W8 for sim unlocking ? which one is easier to unlock?

As a policy, the device can be unlocked with the T-Mobile Device Unlock app 40 days after you activate the device for the first time and if the device is paid in full. To activate the device, the SIM card must be inserted into the phone and be active in the device for 72 hours for it to register in T-Mobile's system.
If the device is not paid in full or if you do not want to wait the full 40 days, you can pay for the device to be unlocked remotely through Android SIM Unlock or similar websites. http://www.androidsimunlock.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/
Just make sure you're choosing the Device Unlock service since a standard SIM unlock service will not work since you are not able to insert a SIM unlock code into the phone.

Same.
What is the proper procedure to unlock an att s9 to use with another carrier?

The process is basically the same as any other smartphone. Buy an unlock code (this should work for you http://www.androidsimunlock.com/unlock-phone/samsung/galaxy-s9/), insert a SIM card from another service provider, this will prompt the SIM unlock screen, enter the code your purchased and the phone will be unlocked.

wait for few days. some developer will develop customer rome for samsung galaxy s9 then root your mobile and flash it and you mobile will be unlocked. s8 custom rom are available.

SamKey.Info supported directly unlock via usb cable !

Don't waste money on this website it's a scam i tried and my phone is still sim locked

T-Mobile S9+
So I purchased this phone from T-Mobile, and tried to switch to sprint. I had it unlocked but they still couldn't pry the phone. It seemed to have only unlocked it to AT&T. Has anyone else home through this or know how to fix this issue?

You can get any S9 or S9+ variant unlocked through Ebay including Sprint:
https://m.ebay.com/itm/SPRINT-SAMSU...?_trksid=p3984.m1561.l2649&_mwBanner=1&_rdt=1
Also can do Bad IMEI devices also. Look through items for other carriers. 100%guarantee.

Be very careful that it has a clean IMEI. If it's a stolen phone then you have a nice expensive paperweight.

If your buy your Samsung galaxy S9 or S9 plus from t-mobile and want to use at&t after unlocking, then you have to use the t-mobile device unlock app to unlock your phone. This is the only option to unlock your t-mobile Samsung S9 or S9+. Only phones purchased from other than t-mobile or metropcs usa can be unlocked using unlock code.
You need open the t-mobile device unlock app and select the permanent unlock option to proceed. you will get unlock successful message and it is unlocked. if you are getting the message "Unlock Failed: This mobile wireless device is not eligible for unlock. For Device Unlock eligibility details, please go online or contact Customer Care." then you have to submit your request for unlocking to any third party unlocking service.
You can can use the below links to submit your request to unlock your Samsung galaxy S9 or S9+ through t-mobile device unlock app
unlock samsung galaxy s9
unlock samsung galaxu s9+

https://www.samsungsimunlock.com/sam...y-s9.htm#model service didn't work for t-mobile.. got the successful unlock message but didn't work with at&t sim.. waste of $13

What if any Verizon MVNO does the Tmo(HD1907) work on?

I switched to US Mobile to get Verizon because my friend also has a 7T on UsMo vzw; however, he has the global version and I have the TMo version. At that point I had figured the hardware was the same, but I can't even get past US Mobile's iemi check to activate my phone on Verizon. I've checked some other mvnos and the same thing keeps happening.... IMEI is not supported.
1. What mvno has anybody actually had their Timo(HD1907) version activated on Verizon?
If so, did it require any trickery?
2. My buddy has a Glaxy S10 on Verizon proper. Could I use his IMEI to activate the Sim and then just put the Sim in my 7t?

Assuming the 1907 has the necessary bands for VZW then yes this should work. I often just ask for the IMEI of verizon craigslist sellers then input that into the VZW website portal to get activated. I actually have a small collection of them, as acquiring one in store from a display unit doesnt usually work anymore since those are blacklisted for store use only.
