[Q] help with SM-925V - Upgrading, Modifying and Unlocking

I just picked up a Samsung S6 Edge 925V and I am starting to think this phone is completely useless here. I have a SIM chip from Telcel in Mexico. I popped in the chip expecting a screen to enter an unlock code but instead I have the message "SIM card is not from Verizon" and not LTE signal. I thought that I would be able to install SM-925I but I"ve been reading that is not possible.
Any help or suggestions would be appreciated!

Verizon Note 5 has a locked bootloader..you cannot flash anything other than stock Verizon firmware on it. As for unlocking for use on other networks, you need to either contact Verizon or look for a reliable online unlocking service

How to get past "network SIM unlock code" screen on brand new SGH-I257?

Hey All,
I need some help understanding what I need to do to get my phone's "network SIM unlock code" issue resolved. I bought a brand new Galaxy S4 mini SGH-I257 (AT&T version) to use with Ting off E-Bay. I have previously owned versions of this phone working without any problem. I have tried the AT&T unlock webpage, but it doesn't recognize the IMEI number, so I called and the support person said it's not in their database. I've searched for awhile without finding much useful information. I'm not sure if it's locked or not. How can I get past the "network SIM unlock code" screen?
Thanks In Advance,

Unlocking my T-Mobile Galaxy S6 edge + to Verizon Possible?

All,
First off, I want to get it out there that this question has nothing to do with rooting and / or flashing custom ROMs. I have recently acquired a T-Mobile S6 Edge Plus recently and am desperately trying to get it unlocked to Verizon, is this possible? Without issue for me to get this process done? Will I lose an quality, features? service disruptions? any instability and reliability whatsoever? Is this a fruitless endeavor? Waste of my money? I get that GSM vs. CDMA are operating on 2 different bands, but I have also heard that this doesn't cause any issues. Please help me, I really want to use my beast of a phone on Verizon's network since that is my carrier and don't plan on changing to a GSM carrier anytime soon. Thoughts? Suggestions? Also, who would be a reliable source or mom and Pop shop that I can go to in Chicagoland? I don't want to do this Unlock business online if I can help it. Any ideas on how much this service will cost me? $40? or would it be closer to $100? Last I heard, even if I went it got it unlocked to CDMA, I would lose Internet service period. Is this a true statement? (FYI, I understand there are no issues from unlocking within and between AT&T to T-Mobile and vice versa.) But GSM to CDMA is another story.
Thanks for reading folks!

Yes it will work just fine after unlocking the phone as long as you get a micro sim card from Verizon.
If the phone has been paid off for over 30 days then you can use the free "Tmobile Device Unlock" app to unlock
it and if the phone is STOCK and no one deleted the unlock app it should be in the app drawer of the phone.
If the "Device Unlock" app is not in the app drawer then you can simply download it from the playstore.
To unlock it with the unlock app it only takes one click. (you can choose between permanent or temporary unlock)
Here is the direct playstore link for the Tmobile Device Unlock app in case you need it.
https://play.google.com/store/apps/details?id=com.tmobile.simlock&hl=en
Here is Tmobile's "Device Unlock" step by step instruction link in case you need it:
https://support.t-mobile.com/docs/DOC-14011
I unlocked my Tmobile S6 Edge+ and when I go into Settings>Mobile networks and click on
"Network operators" then click "Search Now" it displays Tmobile, AT&T and Verizon as options.
The only functions which I know will NOT work using Verizon sim card is wifi calling and video calling.
Also you will need to setup your APN to match Verizon's APN settings.
If you have or know of someone who has a Verizon phone you can simply go into it's settings and
"Settings>Mobile networks>Access point names and edit your phone's access point names settings
making it the same as the Verizon phone's access point names. (this is for Internet to work)
P.s. If the Unlock Device app does NOT unlock your phone it means that it's either not paid off or it has been stolen. (Blacklisted)
Good luck,
Have a great day!

Sprint Note 4 weird when I put in a AT&T SIM Card. Help!

OK, so this weekend I decided to try my AT&T SIM Card with my Note 4 from Sprint. I thought it would ask me for a SIM unlock code or something but it recognized the card and showed "3G". However, I got the card icon which said "Invalid SIM Card".
Any idea why I did not get the prompt to input unlock code? Thanks!

The sim inside the sprint note 4 is only to access the LTE network. So since you took the sprint sim out, you would be only receiving 3g. That is why you are receiving the invalid sim card error, because its not using it.

So I am getting that error because the SIM card is not using LTE? I don't get it. If the phone is unlocked, shouldn't it ask for an unlock code?

There's been plenty of discussion in this forum about bringing SM-N910P to other networks. I'm no expert, haven't done it myself but what I read repeatedly posted is that radios in this version did not allow LTE on domestic carriers when unlocked. Seems a common issue with phones made for CDMA carriers; taking them to another carrier may not meet your expectations. If the limitations are acceptable, maybe you consider going ahead and weigh your options.
Again, there's plenty of threads in this forum discussing this but here's one that I found that may help. To me, it's been rare for @idone to post these days but he posted here.

Thanks for the reply. Yeah I am aware that the Sprint Note 4 would give me 3G or H+ but not LTE which is fine by me. I was wondering why the phone did not ask me for the Unlock code to begin with when I threw a GSM card in there.

Did you find your answer? Or still asking?
It's likely Sprint will give you a MSL number but not unlock the phone to use on domestic carriers. I think you still need to unlock it for that purpose. But the developer I referred you to can do this with or without the MSL. His tools are capable; his service is a full unlock for domestic. I don't think you need the unlock for carriers outside the U.S. the way the phone is currently. Sprint may clear a phone for domestic carrier use but not unlock it or help you activate it. You'll likely find no carrier to help you unlock it either.
I'm sure there are ways to do it yourself but it's gotten more complex with Lollipop and Marshmallow. I'm just not sure how it's done because I haven't fully done it. Only walked through it partially back in KitKat but kept Sprint SIM and service. Didn't try another SIM card.

No I'm still looking for an answer. I have messaged idone on their website and sent a PM. I need this unlocked and take it to H2O. Sprint gave me the MSL code to be given to a GSM carrier but I call BS on that. Strange thing is the damn phone recognizes the AT&T SIM card as a 3G card all right but still says "Invalid SIM Card".

No expert here, but dont you need an AT&T SIM card that has your phone unique ID info programmed into it so it registers on AT&Ts network?
I thought the MSL would just unlock an area in the phone where you would change DNS type info to AT&T's towers/network.

Verizon SIM in CARRIER UNLOCKED T-Mobile s8+ not working

Hi
I have a carrier unlocked T-Mobile s8+ and need to use a Verizon SIM in it and am getting errors trying to use a verizon SIM. The Verizon SIM is from another phone and is already registered. I put the IMEI number of the phone into Verizons web portal to test compatibility and it failed. Does that mean there is no way to get this combination to work? Does the IMEI need to be in the VZW database for this to work? Will flashing XAA guarantee this to work? Thanks for any help and advice.

do u have a tmobile phone, it is different than the carrier unlocked phone, those are 2 different models,
the carrier unlocked.. the sim is unlocked..
the tmobile is not carrier unlocked, and by flashing the firmware of the unlocked version, will NOT unlock the sim.. u will need to device unlock app with the tmobile phone 1st... and usually tmobile will NOT unlock unless u have paid it off and using on their system for 40 days..
others like me had it unlocked with days of service, cause we are tmobile customers for years already... I on the other hand bought the phone on ebay from someone who bought it from Samsung and the imei was not added to tmobile system and I had to call tmobile to add the imei which took about 3 days, then to call back to request the sim unlock which took another 3 days, the device unlock app unlocked the phone instantly...
that was my process for me to get the sim unlock... but if urs it not unlocked and is paid off, another way to get it unlocked it to give it to someone u know, let them use it and call tmobile to start the above process...
Hope that sums up what must be done...

Hi thanks for the explanation, I am pretty familiar with the differences between carrier (SIM) unlock and unlocked firmware as I have flashed Android in the past. I had the phone carrier (SIM) unlocked by T-Mobile through their app and I was still not able to use the Verizon SIM in my phone (not registered error). It turns out (and I found this out by reading through the many messages in this forum) that T-Mobile firmware apparently disables some frequencies that other carriers may use. Once I flashed the XAA unlocked *firmware*, I popped in my Verizon SIM and it worked like a charm. I hope this info is useful to someone at some time and I thank all of you for your contributions to getting this working. KUDOS!

Good to know, but sound weird, thought T-Mobile phones work for all gsm Sims just needing to change apn,
But now cdma merging with gsm, that's so much better as far as phones go, use any phone now from any provider.
Look how the s8 plus is all the same software and the same hardware, just different carrier stuff..

I thought it was weird too. Busted my head for a couple of days trying to figure it out. Is Verizon still CDMA? *scratches head*
Yes, their 3g and 2g networks are CDMA.
If you insert Verizon sim into T-mobile phone, you'll get LTE data, but you won't be able to make calls. Only data will work. T-mobile firmware support band 2, 4 and 13, so you should have data, but not phone service. If you don't have data icon, you'll need add Verizon apn.
FYI
Flashing the phone with G955U1 firmware fixed this issue. I am now able to use this successfully on Verizon.

Galaxy S9 Locked to Carrier

I bought a used Galaxy S9 off Craigslist that was locked to AT&T with hopes I could unlock the phone and switch over to my carrier. In the process, I found out that the person who owned it before was STILL paying it off. Contacting AT&T gave no results, so I'm hoping someone with the smarts on here may know.
After putting in the SIM I ordered, I was prompted an Enter Network Unlock Code screen. I guessed easy numbers, but none worked. Does anyone know what I can do?
It's an SM-G960U running Android 9.0
I'm completely familiar with rooting devices, so if that's what it takes to get the unlock code it's no issue.
