[Q] Going from one carrier to another

The company I work for is changing carriers - VZW to AT&T.

That should be a simple matter - just change the nano-sim since our phone is unlocked and all network capable.

My boss is trying to tell me that AT&T has had problems with this phone. Can anyone here confirm problems?

how to find which carrier is my phone locked to

I have a samsung S2 (GT-I9100), I was using it in my country (Tunisia) for years, then i went to belgium, and bought a sim from there, and it also was working well. When i went to back to tunisia, I tried to update my android (with the Belgian SIM on) version from 4.0.3 to 4.1.2, but the device got locked! each time it asks me for the network sim pin. How can this happen? the device was not bought from an operator. And my main question is how can i find out which operator locked my phone, so i can ask them for a PIN?

Thank you

Need to bypass carrier lock

I have a T-mobile Avant that I would like to use my Metro PCS sim card with. The device unlock app does not work, refers me to Tmobile Customer Care. & they do not care, I have not been able to get any help from them. I am not arguing with them anymore. I am rooted, can install any custom roms if needed. Please tell me that I can bypass this somehow before I go crazy. Thank you in advance for any help

carrier locked phone

I'm currently with Consumer Cellular, brought my moto g from them. They have my phone locked currently and I can't switch to another carrier for another 3 months. My question is, does anyone know if it matters if I flash a custom rom, which will replace the factory rom, if it will prevent me from unlocking the phone when the time comes to enter the unlock code they will provide.

Asking because I don't know if the OS they provide when you buy the phone has any special features that control the operating of the sim card. When I try to boot with a different sim a window comes up asking for a code.
Thanks in advance.

Carrier compatibility?

Any way I can make this phone work on Sprint? It is unlocked and I can root it and put a new ROM if necessary. Thanks in advance.

Unlock my HTC One to O2 (Carrier Unlock)

I have S-OFF, and I`m really struggling to figure out how to do this.

I`ve tried installing RUUs via .exe and ZIP, but they both fail and I think I must be doing something wrong.

I thought this would be a lot simpler than it is...

Can anyone help, please?

Carrier Updates

I just bought a used T-Mobile Gear S2. I think (sadly) I know the answer but wanted to check. Are updates for the carrier versions maintained by the carrier or Samsung?

Carrier bootscreen, Icons, Camera and Hicare questions.

So I upgraded to the current build I am on (info in attached screenshot) from the earliest build I could find and all builds I upgraded to and from are Europe based. My question is why did this completely remove my carriers bootscreen? I'm with Spark NZ.
My other question is all my Google based icons are now showing as they are meant to (see screenshot). Was this also a result of upgrading to MM? The other build of MM I tried didn't do this so I'm curious.
My camera is also now no longer taking full screen pics, it seems that something went wrong and now it all comes out in little(r) box(es) rather than nice full screen images.
Last but not least, Hicare. This has been working along side and sometimes over top of Play Store in updating certain apps includingthe Play Store. Is it supposed to be doing that?

carrier locked phone

My moto G 3rd generation is currently locked by my carrier. Have 3 more months until they will give me the unlock code. My question is, if I root and install custom rom, does that have anything to do with the carrier network locking? Will installing a Custom rom do away with the lock allowing me to change carrier's. Should I just wait until the phone has been carrier unlocked. Thanks!

Can't get connection to ANY carrier

Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:

• Factory reset


• Reinstalled CM


• Put paper under the sim for tighter fit


• Turned the radio off and on and restart phone


• Change pin code


• Replace sim-card


• Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)


• Total restore by fastboot-flashing


• Installed OxigenOS 2


• Tried all modems from the modem collection on CM and Oxigen.


• Retyped the APN by hand


• Opened the phone again and checked that all cables are connected well


• Tried manualy connect to my carrier under Network Operators

For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.

I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!

Q's about repacing motherboard. Newer model? Different carrier?

So i recently hard bricked my h810 g4. (backstory post #2)

I was looking into replacing just the motherboard. I came across some cheap ones for t-moblile. Which would be nice because thats the service i use plus they are more rootable. Even it i get a blocked one, If i can get it to boot up i can sell it for parts with proof that it actually works.

Is it possible to swap the motherboard with one from a different carrier?

Also my phone was a beta phone. Serial starts with 503, so im wondering if i can even replace it with another h810.

Any advice would help.

Thanks

Cross Carrier HD/VoLTE Rollout

Gentleman, Cross carrier HD Voice / VOLTE appears to finally be a real thing.

A few minutes ago I had my first HD VOLTE call with my mother. I'm Verizon/N6p, She's ATT/Iphone6. We're both in Brevard County Florida

A quick googlin' shows they are rolling this out in select markets.

Anyone else seeing this with other carriers or other areas?
