Hi experts,
Here on xda-developers, I read, that if we get the Samsung Galaxy S3, with the Exynos Processors, the APNs can be modified and can be used as a World Phone.
That means, if we are in the US we can use Verizon 4G LTE Network.
If we go to Europe, we can use the local SIM Card and use the local 4G LTE even from a GSM or a CDMA provider.
Here are my questions.
1. Is this possible? Is the information true?
Here is the link for that.
http://www.xda-developers.com/android/port-us-galaxy-s-iii-roms-to-other-variants/
If this is possible, can the same be applied to the Snap Dragon Processors?
Swapping the Samsung Galaxy S3 between different carriers, Is this possible?
From Verizon to use it with AT&T and vice versa?
2. There is also a thread which shows that, the Galaxy S3 can now be booted from a SD Card.
Here is the link for that.
http://www.xda-developers.com/andro...ader-released-for-galaxy-s-iii-galaxy-camera/
If that is possible, can the Bricked G3 Phones from Verizon or AT&T can be reused?
Thanks a lot for the answers and sharing of Your wisdom on this.
Peace,
A J.
I'm travelling to Canada next week and am buying a $10 micro SIM card and a $20 prepaid plan from Rogers Wireless.
One of the Verizon Global support team people I spoke to on the phone said that the S3 will work the way you want as long as it has the latest stock JB OTA update. (That's the 4.1.1 / VRBLK3 update for anyone reading this in the future). Most importantly, the patch unlocks the phone to use on foreign carriers, so I was told I was already good to go without any added steps on Verizon's part or mine.
Of course, I'm running a rooted version of VRBLK3. Don't know if that affects global capability, but I'll let you know if this works for me or not in British Columbia.
i dont know if you will get full capabilities in terms of data signal but i know i can get call the text to work. depends on what frequencies the phone has or allows you to have.
look here for some related info.

Reporting back - I was able to get voice service in Canada with a Rogers Wireless SIM, but no data. The pohne couldn't register an APN - couldn't manually enter any information into it either.
So there you go.
how is the 4g service in Canada?

You needed to download "APN Manager Pro" to edit your APN's as per the Global roaming thread in the dev section. You would have had data to some extent had you done this.
Hi guys,
I bought an unlocked verizon samsung galaxy note 5. I couldn't use T-mobile mobile data on the phone till I asked help from specialist. They helped me to create a new T-mobile APN. Though, I couldn't be on LTE. Anyone knows why and can explain to me more ?
What if I travel outside the states, how do I use another carriers mobile network on my phone ? Do I have to create their APN too ?
Thanks
i know there is a bunch of info on the internet about this. but everyone references a international unlocked phone. if i upgrade to the note 8 unlocked over AT&T offered on their site will i lose wifi calling and or any other features?
I wish I would have known that WiFi calling wasn't supported on unlocked Note 10 + before purchase. I need WiFi calling and so I am trying to flash the T-Mobile firmware onto my Unlocked Note 10 +. The problem is that I am not getting any of the T-Mobile branding or features after flashing. I think this is because it doesn't recognize my SIM as being a T-Mobile SIM. I use Mint Mobile which is a MVNO running off the T-Mobile network. If I would have just kept my Google Pixel I would have all the features that I need that T-Mobile offers such as the WiFi calling and HD voice.
Is there any way for force the device to enable the T-Mobile specific features available in the firmware? I am thinking about going and pickup a prepaid T-Mobile SIM to see if it will activate the features with that. I am beyond frustrated at this point as I have an expensive phone that I can't get any of the features on that I had on my Pixel 2 XL.
Any help is greatly appreciated.

I have an unlocked Note10+ (N975U1) with T-Mobile (standard unlimited-everything plan), and WiFi calling works fine for me with the default unlocked firmware.
You may be right about the sim card. If T-Mobile is your carrier, can you get a regular sim card from them?

I don't know the answer to your question, but can tell you of a similar experience I had buying an unlocked Note 8 from Samsung and trying to use it on Verizon network. No WiFi calling, visual voicemail and other notification features, in spite of hours spent on phone with Samsung and Verizon. I ended up returning it and buying the Verizon branded one. Lesson learned! There are cons as well as pros with unlocked phones.

It depends on the carrier. T-Mobile is good about supporting its features on unlocked Notes, definitely including WiFi calling. Verizon is not.

WiFi calling does appear to be working now on the unlocked firmware for me. I have the latest update that was just pushed a few days ago.
Hello, I hope someone here can help me, since I've already tried everything I know.
I bought a OnePlus 7 Pro 5g from ebay (https://www.ebay.com/itm/193541542389?ViewItem=&item=193541542389) because I checked on T-Mobiles website and it says it was carrier compatible I'm also aware that the 5g won't work on T-Mobile. The seller assures me the device is unlocked and when I go into System Updates, it says below UICC Unlock that the device is unlocked. But when I insert my T-Mobile sim card it won't connect to the network. These are the things I tried:
Inserted the T-Mobile sim card but it won't connect to the network.
Tried going into settings/SIM & Network/Network Operators and chose T-Mobile 4g but after a while it says the sim card can't register to the selected network.
Tried T-mobile customer support and they say I need to talk to Sprint.
Talked to Sprint customer support and they said I need a new sim card.
Went to T-Mobile and got a new sim card but still nothing.
Did a factory reset but still did not work.
Wiped data & cache but still not working.
Tried updating PRL, Profile and UICC Unlock under the System Updates Setting of the phone using WIFI internet and I got an error.
I don't know what else to try. I even contacted the seller and he assures me the phone is unlocked and that it should work without a problem. I'm in Puerto Rico and using T-Mobile but I can't get this to work no matter what. Can anyone provide some insight on this or does someone here has any experience using this model (GM1925) with T-Mobile?
*Edit*
Forgot to add. When I insert the SIM card and it tries to connect to the network, after a while I get a notification that's titled Phone Services and it says Phone not allowed for voice. Anyone know what that means?
Have you tried with Force LTE app on Android and selecting the correct mode for Tmobile?
Had a similar issue when using Visible phone on Tmobile. After using the App and selecting the correct Network Mode was able to get everything working

Well my problem was solved. According to an awesome telegram group I found and with the help of an awesome member called Chris Starling, we managed to get the phone working. Turns out that some Sprint phones being sold on ebay are semi-blacklisted and will not work with US carriers. The method to solve the problem involves tampering with the IMEI and I barely understood it, the member Chris basically did everything and got the phone working again. So this thread can be closed.
I suggest that no one buy phones from the same seller I got it from.
Hi Lpedraja2002,
If possible can you please elaborate on your solution? I am faced with this same issue, a locked Sprint SIM from an ebay scam. I am familiar with the concept of rooting and changing the IMEI using a root app, but would love to know some more details.
Cheers
Hi.
I also have the same issue. I got the gm1925 model as present. I'm not living in USA but can't use the network in my country. I try 3 sim from several Carrier but it didn't work.
Can you please tell as how you did it.
There is a MSM tool tutorial for unlocking the bootloader on the locked 5G variant. Normally blowing away the software from recovery would work but if Sprint locked the SIM via the IMEI number than it should be possible to unlock the SIM by changing the IMEI. I will be trying this soon using a IMEI changer root app, or maybe using ADB or something. Will update next week.
Edit: can confirm it is impossible to unlock the sim, even by changing the IMEI. One has to get in contact with Sprint.
Following up on this as I recently purchased a OnePlus 7 Pro 5G and am now stuck with it. Wish I read this thread earlier. Can you pass along your contact Chris Starling if he would be able to help?
If it's who I'm thinking of I may know the guy.

If you guys could please edit your posts to not include first and last names that would be wonderful.
Usernames exist for a reason.
Pm if you need help with a semi-blacklisted device, and also don't discuss IMEI flashing on XDA it's against the rules.
i need a help on sim unlock oneplus 7 pro (Sprint) and oneplus 8 (tmobile or Sprint)
I have a Sprint GM 1925 that is debranded and sim unlocked. Both Verizon and T-Mobile confirm it is unlocked but it shows as not compatible and can't be activated by either carrier. I also get a notification that's titled Phone Services and it says Phone not allowed for voice when inserting a T-Mobil SIM. So any help guys?
To everyone here I might have a possible solution.
I was looking for the answer here and didn't found it, so contacted sprint by chat by this link https://www.sprint.com/en/legal/unlocking-your-sprint-device.html talked through chat and waited for 30 minutes. Then I looked for system/updates and then click the UICC unlock it search out for updates and then unlocked the phone. My phone is a one plus 7 pro gm1925. Just hope this could help someone out here.
Hi all,
Amazon and many online retailers are selling this model GM1925. Please advise whether it’s worth to buy. My friend bought this and using via T-Mobile network with 4g however it’s not working with Xfinity Mobile network sim.
