unlocked phone get OTA update on different network

Cant seem to get a concrete answer anywhere. I Sim unlocked my tmobile note 3 and I'm currently running it on the ATT network. Will I get OTA updates from Tmobile still or just nothing at all?

If you're running a completely stock rom (no root or recovery) you will get updates still.

If you are rooted, your phone will attempt to download OTA updates but most likely they wont install and you will lose root. This happens on the S3 and S4... so N3 shoulnt be any different.

If your phone is NOT rooted and if you have the stock firmware in the phone then:
You will only get updates for AT&T if you have an AT&T activated sim card in the phone.
Without a activated Tmobile sim card in the phonoe you will never get tmobile updates.
Good luck!

Thats what I figured, if it is Tmobile, you will get the ATT update, and that might be an issue. I am watching the forums for any post of an OTA, then will swap cards back.

There is no way that tmo phone will accept att ota even with active att sim on it. Ota checks phone model and att ota wont show at all on tmobile phone. You can always download latest update from samsung website

So is the simple solution just to use Samsung Kies? I bought a 2nd hand Galaxy S5 and it had been on O2 but unlocked. I'm now using it on EE (I'm in the UK). Will Kies let me do an in place upgrade without having to wipe?

so would my unlocked Verizon Google Pixel phone get the Android 9.0 PIE update when i'm using a MetroPCS sim ?

[Q] Which LG G# comes with unlocked bootloader?

I am an AT&T subscriber and in the market for an LG G3. The AT&T version comes with a locked bootloader which means I will probably never be able to install a custom recovery and flash CyanogenMod on it which is a must for me. I realize that other versions will not work with AT&T LTE and I am completely fine with just HSDPA+ - which versions of the phone support AT&T HSDPA+ and come with unlocked bootloader?

Thank you. Does it come network unlocked? I.e. can I put my AT&T sim in and use it?

No, but I've heard of getting unlock codes for as little as $6 on Ebay.
Plus Tmo is rumored to start a new thing soon where they put an unlock app either on the phone itself or on the Play Store and you can unlock it right there.
You'd want to get the Tmo version, though, because it's fully compatable with AT&T's LTE bands.

Need somebody to help me about network unlock.

I'm sorry but I have some questions. Hope you guys can help me out.
1. Can I flash the U1 firmware(unlocked) to get sim unlocked on my T-mobile S8+?
Because I'm not American, I need to sim unlocked my phone to use my country's carrier.
2. If the first one doesn't work, can I flash the s8+ sprint firmware on my s8+ T-mobile and after that can I sim unlock the T-mobile s8+ with buying the Sprint unlock code?
Because in my country, T-mobile sim unlock is much higher than the others.
Forgive me if my worse Engish bothered you.
Thank you so much.

From what I know it has to be unlocked through tmobile. Flashing different firmwares won't do anything and in the case of the u1 firmware all it does is remove carrier apps it does not unlock the phone to be used on other carriers.

AT&T sim unlocked. Should I flash unlocked firmware?

I just received my sim unlock code from AT&T. Going to unlock the device tomorrow with a project FI sim. Should I then flash Samsung's s9 unlocked firmware? Or is it not compatible with AT&T hardware?
Thanks.

If you unlock it (with the help of AT&T), why would you mingle with flashing the firmware? I mean, there's no point in doing it. Your phone will work with any other network, so you don't have to do anything else with it.

In my research I read that firmware/os updates, such as monthly security updates, will not download/install without an AT&T sim card installed in the phone. So, if I were to use the phone with another carrier, I would be forfeiting any and all software updates.

Yes, that's right too. It's all down to how comfortable are you with these changes

Question Carrier unlocked and unlocking bootloader for use on VZW

Hi all,
I've always had carrier locked phones on Verizon/Verizon models (S3, Note 4, Note 8 - all rooted, only Note 8 with locked bootloader) and I will be getting the 6 pro in the carrier unlocked variant from the Google store. I plan to root when available. As mentioned, I plan to use this on Verizon networks.
I've read some conflicting information regarding bootloader unlocking for carrier unlocked devices to be used on Verizon so just wanted to clarify:
If I buy a carrier unlocked 6 pro, insert my Verizon sim card and set up the phone, will I be able to unlock the bootloader at a later point? Or do I need to unlock the bootloader before inserting the Verizon sim card for the first time?
I realize obviously we don't have the phones yet, but I am presuming this is more of a general question/use case. I've read in multiple spots (here on XDA and other android forums) stating that you need to unlock bootloader before inserting the sim card, but also read that you can do it at any point since the sim card doesn't deny access to those operations. So just looking for what is actually the correct answer.

My last several devices have been carrier unlocked, and rooted, while on the Verizon network.
Unless the p6/p6 pro is different than my previous carrier unlocked Google phones, there should be no problem using a Verizon sim in a carrier unlocked device that's rooted.
The only issue I've had with Verizon with a carrier unlocked device is if it is a device they (VZW) do not offer, you cannot use VZW warranty, and you cannot get the free cloud account that comes with a Verizon device.
Of course that may have changed as well, but I've never had an issue with a carrier unlocked Google phone being rooted while using a Verizon sim card.
Hope this helps.

Thanks for the response. So just to clarify:
Unless the 6/6 pro is different, a carrier unlocked variant can have its bootloader unlocked at any point - whether it be right away or after the sim card is initially inserted/phone gets activated?

Yes. That is my experience with all my previous carrier unlocked Google devices that were on the Verizon network.
IIRC, all were rooted AFTER activation on VZW network via sim.

Awesome. Thanks for the clarification!
Hopefully anyone who has the same question sees this thread.

To clarify, you are referring to buying the Verizon variant directly from the Google online store?
