I bought my One in the UK and, as far as I'm aware, it's locked to Three (the network I bought it from). Since I've come to China and South East Asia, I do not get any signal on my phone. My girlfriend who has an iPhone 3Gs and is also on Three gets signal (or she did before she cancelled her contract).
Should I get signal out here? I thought the phone would be able to work anywhere in the world in spite of where it was purchased. Anybody know anything about this? It's rooted and I have a custom ROM and custom firmware installed. Pretty sure I also updated the radio manually too, but I can't remember.

Its not working because the phone is SIM-locked to Three network. You will have to SIM unlock the phone.

Request an unlock code and continue the process. Then, your SIM will be unlocked and you will be able to use it anywhere

Huh, I thought that would only happen if I tried to put a non-Three SIM in the phone. Thanks, man
If you have your UK SIM in there, maybe you need to activate roaming on the network. But you know what they're like, you can only do that whilst in the UK.
Get an unlock code from eBay or a website and buy a local SIM, it'll save you money in days or even hours given the stupendous price of data roaming.
Hi everyone,
i got a Sprint HTC One M8 from ebay, it is new but i was planning to use it on AT&T network, since it have a Sim Card Slot. Furthermore, even though i'm living on the US now, i'm from Brazil and i was planning to use the phone there as well.
And now starts the problem.
I called the previous owner, asked him to contact sprint to make the sim unlock procedure. He did so, providing me the MSL for the phone. The next step, he said, was to "flash" the phone on AT&T in order to get it connected to their network. I tried several sims, even bought a new one and activated it but with no success.
I spend almost 2 hours on the phone with the sprint's international support, and all they said was that they did everything that they could about unlocking my phone and now i should contact AT&T.
I'm afraid of staying on this infinite loop and i want your opinion.
Does anyone in fact unlocked their SPRINT phone to use on another GSM US carrier? If yes, what did you do? Because i'm planning to return the phone and ask for my money back.
BUT, with the "International Unlock" i should be able to use the phone on ANY international carrier? Because if that is the case, maybe i keep the phone to use when i go back to Brazil.
Thank you very much!

On the CDMA version of the M8, it lacks the LTE bands needed for Domestic carriers. You can use it overseas somewhat, but not too well. If I was you, I'd grab a Droid Turbo for ~$200-$250 off eBay. It just recently got its bootloader unlocked finally
Hi,
I am using samsung Galaxy S6 ATT version with the following software version:
Android Version 6.0.1
Android Security Patch September 1,2016
Baseband Version G920AUCS5DPI1
Build number MMB29K.G920AUCS5DPI1
The phone is sim unlocked but I need help with rooting / unlocking the bootloader. On checking this forum I did not find any way to do this on my. So I was just wondering if there is anything else (such as installing any other ROM) that I can do with this phone.
Since the contract on my phone has expired I tried using this phone with another carrier and it does not seem to be working (tried with metroPCS) the phone does not show any other network operators except ATT/T-mobile and Verizon and on trying to connect to T-mobile it fails to connect (metro PCS uses T-mobile line)
After spending few hours with an account rep from metro he felt the phone may not be compatible. So at this point I am just trying to figure out if there is anything I can do with this device.
Sorry for the long winded post but I just hate how these carriers tell you that after the contract you own the device but their own software updates mess up any chance of using your own device as you want.
Appreciate any insight or links to help me figure out if anything can be down to get rid of the ATT rom.
Thanks,
Matt
You can use it for a wifi hotspot or spare android device. no roms, no custom recovery, no bootloader unlock, no real root option. sadly. this device thanks to att gets no love.

This is very sad. what is the point of paying the bloated ATT bill and getting the phone sim unlocked after 2 years of payments. Wish someone could sue these big carriers with their dealing with locking devices that are not really theirs to lock after a period of time.

Correct that there is no bootloader unlock, so no custom ROMs.
However, Sim unlocking should get you functionality on MetroPCS, among other carriers. According to willmyphonework, you should be able to get on MetroPCS 3g on 1900mhz band, and LTE band 4. Whether or not towers on those frequencies exist in your area is another matter. Did you verify the device was using the correct APN data when you tried non-ATT Sims?
Hi dandrumheller, sorry for the late response. I did verify that the APN was setup correctly even set it up manually with the metropcs customer service but the phone still does not show metropcs as an available network. It does show ATT/T-Mobile/Verizon as the available options and does not work on choosing T-Mobile (Metropcs uses t-mobile network). When I put the sim in my other phones they all work fine and show 4g lte availability from metropcs in my area. so I thought my only option is to unlock the bootloader and try my own rom instead of the good for nothing ATT rom.

I want to get a v40 to replace my Redmi Note 7
I use T-Mobile but know not to get the T-Mobile v40. So I was curious if it would be better for me to get a different one and unlock it or what should I do?
Any advice would be great because I don't want to put my self in a pickle where I have a nice paperweight
No need to get a TMo version.
A cross flashed Sprint V405UA to LG v405QA will work on TMo and get all TMo bands, plus TMo VoLTE and TMo VoWi-FI and TMo HD Voice. I know because that's the model I bought, cross flashed, and use on TMo.
I see no reason why a cross flashed Verizon or ATT wouldn't be equally good. But I can't speak there from personal experience.
But there's no cross-flashing possible on a TMo version. Once TMo, always TMo.

I saw you in some other posts and I was hoping to get you to respond to this. Thank you. I'll have to keep my eye out to see if I can find a sprint one. I like my redmi note 7, but there are many features that I want that it just simply doesn't have. But are there any other weird quirks I should know? Again, thank you.
Thanks for kind words. I seem to have a bit more time on my hands now ... I wonder why ....
The only weird quirks I think are worth mentioning is that it is not easy to root and install TWRP. Several have had issues doing so. It can be done, I and others are living proof, but it's not for the fainthearted. You'll have to bounce back and forth between several threads to get it right. There's no one comprehensive guide. If you're not looking to go that route, there really are no quirks.
As for sourcing one, I picked up mine, a mint condition device, off of eBay for $145. A steal for a phone of this caliber. They seemed to have upped the price in the meantime.

Troubles with getting TWRP working don't bother me. I don't mind that. I love messing with things a little too much. Also, with that link that you sent, although the listing said you can't use third party software to unlock it, you still can. Correct? (Well the listing you sent said that it was sprint only, but not specifically unlocked. But it showed me a similar one that is $170 that says it's sprint locked)(also that because it technically isn't software that you're using to unlock the device.)
And I do wonder why you would have more free time on your hand, I could never tell why...
In many cases, these eBay vendors have no idea what they are selling or what "tethers" come with which phones. See here's the thing. If the device is paid off, it can't/shouldn't be carrier locked. You own it free and clear, and should be able to put it on any carrier with which the phone is compatible.
From reading these forums, I knew I could convert (cross-flash) a v405UA (Sprint) device over to a v405QA (US version) which would enable more bands (that I needed/wanted for my eventual migration to TMo). And if the device in that listing was somehow actually carrier locked to Sprint, I knew I could get Sprint to unlock it. I had Sprint, I knew I was going to use the v40 for a while on Sprint, so I could easily verify its carrier unlocked-ness, and could correct it if needed.
But I didn't need to. The v405ua (which was originally attached to Sprint at some time in the past by a different customer) came to me carrier unlocked. Three weeks later, I had that same device, crossflashed, rooted, with TWRP, on TMo happily making use of the extra TMo bands, VoLTE and VoWi-Fi, and HDVoice (none of which a non-crossflashed v405UA could).

Ok, so if it isn't paid off then the seller is selling a bad phone, and they should list that in the description.
I'll buy the $170 mint condition v40 because it's a good price for the phone, and I'll have something to mess with. Thank you, again. I appreciate all the help.
It'll be nice to have a nicer phone again. I loved my S8 before I broke the screen, and after I had modded it.

I have gotten twrp working along with being able to install linageos
Only issue is that it asks for a password and I don't know what to do from here. I need to sleep.... I've been at this for far too long

Took me like 3 minutes of reading. After wiping data it is fixed. That was easy
I recently got a CN version Mi 11 Ultra after getting tired of waiting for the 12 ultra, only to find I cannot activate it on the ATT network because it is "not a recognized device". I've talked to 3 backend support people who all assured me it is not a compatible phone, they've had other people ask about this, and nothing can be done. However, I've seen threads here and on the ATT forums where people are able to get it to work quite easily. I've followed the advice about disabling carrier VoLTE check, and am on MIUI 13.0.4 Global, but still no bars.
What can be done? Is there another US carrier I can go with for which the phone will work?
Have you tried settings your APN to AT&T 4G?

i am on T-Mobile and got an 11 Ultra last week. i popped out the sim card from my iPhone mini and popped it into my new 11 Ultra and it worked immediately.
as soon as you sign up to their service, you should be good to go
ATT is trash. As soon as you switch to the new phone they will deactivate your account and you have to call them to unlock it. Then they give you this bull about your phone being a 3G device that they won't support anymore. I wasn't even with them a month before I dropped them and went to Google Fi. Best move I ever made. All unlocked devices work on G Fi as far as I have seen.
