Is your device completely paid in full
-- As long as your device is unlocked (60 days after initial purchase from Verizon) then it will work with any SIM
-- Refer to porting out your mobile number to another carrier
-- Power off device, remove SIM card, wait a few minutes, reinsert SIM card and try again

The Verizon modem only works on the Verizon ROM, unfortunately. Unless you want to flash a custom ROM, you have to stick with OxygenOS to keep your cellular data if you have an IN2019.

HTC One S on Orange - Can I remove SIM lock without an Orange SIM?

I am getting an HTC One S that is locked to Orange UK. I'm not in the UK and I'm having a friend ship the phone to me. It is an S4.
This will be my frist Android device, so I'm a bit clueless. I plan on ultimately changing to stock EU firmware, rather than Orange firmware.
Can I change the firmware and remove the SIM lock (I assume simply changing the firmware won't do this?) without an Orange SIM? I have read the threads on how to remove the SIM lock so I'm confident that I can do it, I just don't know what functions can be accessed on the phone without a SIM having never had an Android device before.
I have an Orange uk One S now running trickDroid v7 & if you want to remove the Orange sim lock try this Link http://forum.xda-developers.com/showthread.php?t=1693491

Thanks, I appreciate the reply.
I have been through that link, I just want to check if I can follow that process without having an Orange SIM in the phone at the time. I'm not sure what parts of the phone can be accessed without a SIM in it.
I've not tryed the sim unlock as yet but use without a sim in connect to play store via wireless will work most of the process is done via the app or cmd prompt so should be workable!

Great, that answers my question then, thanks!
No you don't need an Orange SIM card. The SIM unlock procedure actually required you have a SIM from a different provider so you're good to go with what ever SIM you have. Once you insert a SIM card other than Orange SIM, it will ask for a SIM unlock code.

Network locked sim card inserted

My sister presented me this galaxy s6 phone from malaysia. I am from India when i inserted india sim card. I got the message network locked sim card inserted. I came to know from the internet all samsung phones are network locked, for that I have to make incomming or outgoing call for 5 mins. I inserted malaysia sim and (from india) made 3mins of call to malaysia and 2+ mins of call to my mobile in india. Inspite of this my mobile is not unlocked it is still locked. Please help me.
If i flash stock firmware from india will my s6 be automatically unlocked ??, without any side effects.
In internet I saw there are many sites which says they can provide unlock code but their charge is very high almost 50 USD. I have already spent almost 100RM for roaming calls. Please help in unlocking my phone.
Inserting the malaysia sim card will not work as the call has to be made through the network of the region the phone was bought. Using the malaysian sim in india is not enough as the call is still going through the indian phone network.
I already made a 3 mins call to Malaysia . Will it unlock if I ask to someone from Malaysia to make another 2 mins of call to me.
Only way to unlock a network locked S6 is to get the unlock code from your network or buy it online from reputable unlockers. Flashing ROMs will no remove the lock.
Suggest some reputable unlockers

The problem you may have here is unlocking services unlock the phone from a specific carrier. The region lock is not the same as the carrier lock that these companies provide a service for. A quick look on google brings up no results for region unlocking. At the minute your only course of action is take the phone to a samsung repair centre and hope they will remove the region lock for you.
I took my phone to local mobile service center and he unlocked my phone (dont know how he did) and my phone is now rooted. Now my question is, is the unclock permanent and can i flash stock firmware safely without getting locked again.
Please confirm

Sim Unlock is needed once in a lifetime and it`s irreversible. Anyway I don't understand why was needed to root your phone for sim unlock. Normally you can reset, flash anything now and your phone will be sim unlocked.
What do you mean by reset ? we cannot remove the lock by flashing a new ROM.
why dose it come up restart phone when i swich sim cards on my unlocked galaxy s6 eage and dose this lose all othe data and save picuters and contects
Please i do also have S6 brought from USA to Ghana and when i tried put on a sim, it said Network locked sim. please what should i do?

SM-G930F became locked after installing custom ROM

*** UPDATE: it's a SM-G930FD, rather.
Hello,
I have a SM-G930F which I got from a carrier (Smart Telecom) here in the Philippines. It came unlocked on both SIM slots... after flashing the SuperMan-Rom I am unable to use my other SIM (Globe Telecom) on this phone. At first it was asking for a SIM PIN which I don't remember setting and eventually it locked me out asking for a PUK, I contacted my telco for the two PUKs (1 & 2) but neither work. Put the non-working SIM on my old phone and it works.. got the SIM replaced thinking a new one would work but it's still asking for the PUK even from a fresh SIM. Could it be that my phone became "locked" after flashing? Kindly need your help!
Thank you!
Tried flashing stock again?

Phone network locked after flashing through Odin?

Hi,
I have a Samsung S8+ which I bought unlocked to any network, I have used it on EE and Vodafone. I had rooted the phone, flashed different roms etc no problem. After I got my new phone, I tried to get the sim out of the S8+ and the tray was stuck, left with no choice I forced it out but this broke the sim card reader as it wouldn't read any SD or Sim.
I flashed a stock 9.0 pie UK version (Unlocked) to the phone through Odin and got the sim card tray replaced, now it reads SD cards and my sim but it says network locked and is asking for the NUC code, the phone was unlocked before and now it isnt. I've contacted Vodafone for a NUC code but the code isn't working (says incorrect code), I've tried flashing stock 8.0 too, also not working and still asking for the NUC. Strangely, it isn't working on either EE or Vodafone Sims now.
Could the sim card tray being replaced effect this? Is it the software flashed through Odin?
Any help will be appriciated please.
Thanks
Sam
Is it possible not only the SIM tray but the whole motherboard was replaced? It would make perfect sense then. Check whether your IMEI and S/N match what was on the box the phone came in.

Thanks for the replies. Same IMEI which is strange, I've tried all UK sims and it's still locked. It says sim locked enter unlock code now but on every sim

It is strange normally sim unlocks are not undone by odin flashing. Sim unlocks lie in a non flashed partition

You have to wipe the phone to unlock the bootloader. Are you having the OEM Unlock is greyed out issue?
