I recently bought a supposedly unlocked T-Mobile LG G6, but somehow my Verizon SIM card isn't working on it. The previous owner installed the T-Mobile unlock app and successfully unlocked it, so I'm really just not understanding what's going on. I tried to do a factory reset and restart the phone with my new SIM, tried to unlock it again (it says it's already permanently unlocked), etc. Help/advice would be much appreciated!!
is the VZW sim card already activated?
did you try using TMO sim card and see if its working with that?
try with LTE only mode with VZW.
Your tmobile branded G6 might not have all the CDMA bands to work with Verizon.
Verizon still uses CDMA.
If the phone is really unlocked, it will work on AT&T, Crickett, T-Mobile and most GSM networks.

Just a quick question,
I received a galaxy s5 for work today and it is the att version, if I unlock it and use it on tmobile, does it support the same bands as the regular tmobile branded one?? Like LTE and hspa+ 21.
Thanks for all your help ahead of time and tend apologize if this has been posted before, I tried looking for something similar but was not able to find anything.
I have a AT&T Galaxy S5 unlocked. I put my friend's T-Mobile sim card in it and everything worked even LTE without changing anything (APN), it changed automatically. My brother has Claro (by the way I'm in Puerto Rico), with that one I had to change apn's manually to get data working.
I'm freed my AT&T S5 for use on T-Mobile last month and it works just fine. Didn't have to modify any APN settings either as the phone was able to pull it off the T-Mobile SIM.
In all freq's? AWS as well?
SAMSUNG-SM-G900A, with 128gb SD & Rooted.
That's what I'm wondering. I know LTE will work fine. But what about AWS and hspa.
I have unlocked my Z1s from T-Mobile's network so it should work on AT&T as they are both GSM and use most of the same bands. After unlocking it and verifying that my phone is indeed unlocked I put my AT&T SIM card in and the phone reset but it does not recognize the SIM card. Is this something AT&T needs to solve, or is there a way I can remedy this issue?

What method did you use to unlock?

I purchased an unlock code. I entered it and it shows it as being unlocked.
Seems like your phone/imei is blacklisted...query the national blacklist with your imei to get it confirmed
The phone was on T-Mobile's "blacklist", it has since been removed and says that it is ready to be used. The phone still does not read the AT&T SIM card. I am wondering now if the SIM card is locked, or if it is a hardware issue. Thoughts?
my friend just gave me his t-mobile Samsung Galaxy Note 4. i have the unlock code for the device. can i use my sprint sim card on this device? i have code. i tried to unlocked the device and then when i tried to use my cellular date i get this massage "Not registered on network" is it possible to use my sprint sim card on this device.
no. you cannot. needs to be a GSM provider (att or tmobile)

Even if the phone is rooted, unlocked, and the cell network changed to CDMA? I've used some Rom's that allow u to make that change just not sure if it'll actually work. .... thanks for any help
VERY Odd Problem - SIM Card Locked, Requesting PIN. Only on This Phone & SIM Combo
On each boot, the phone asks for "SIM network unlock PIN", and otherwise will read "No SIM card" in the notification bar.
What's odd however is this phone is unlocked. It's an AT&T Nexus 6, and was previously working under Cricket Wireless. The SIM card is from Mint Mobile, and works with my unlocked LG G5. It's only this phone & SIM combination together that's causing issues.
Trying to access APN settings gives the message "Access Point Name settings are not available for this user".
I've tried factory resets, as well as full flashes back to stock, etc.
I've never encountered this before, if anyone has any ideas or input I'd appreciate it.
Sounds like it is NOT unlocked. Since Cricket Wireless is an MVNO directly owned by AT&T, it makes sense to me that an locked AT&T device may work on Cricket.
Test with a friends SIM card. The Nexus 6 works on all carriers in the United States- Sprint, Verizon, Tmobile or AT&T. If their SIM card does the same thing, yea this confirms that it's locked. Buy an unlock code, it should only be a few dollars I reckon.
edit: also please note there is a difference between an unlocked/locked bootloader and unlocked/locked network. They are NOT mutually exclusive.
I purchased a used galaxy s10 G973U from someone who bought directly from samsung.com unlocked version. he used it with tmobile. Now im trying to activate with sprint and it wont let me. Network sim setting show that sim is unlocked. Im trying to activate my phone on sprint website and it says "This phone can't be activated
Sorry, but this phone can't be activated with Sprint service. Try to re-enter your IMEI/MEID or try another phone."
I thought this phone is supposed to be able to be used with both gsm and cdma network carriers. what are my options besides trying to return it?

Did you contact Sprint and get a sim kit sent to you? You'll have to do that and then it should work. If it doesn't after that, I'd initiate a chat with them through the support page on their website.
Another option is to go to a Sprint store to activate it. They will have the sim card available for it. Im using an unlocked model switching between carrier and carrier-free firmware no problem.
(PS, once you do get it working there's a way to enable hotspot support without it on your plan.)?
