I bought 3 US Cellular S5' for resale and I knew they could be unlocked according to US Cellular's device policy. However I went to the store and they "unlocked" it. They said they unlocked it but it wouldn't work because the software only allows you to enable CDMA. If I flashed a custom ROM onto it, would that allow me to enable GSM? Anyone have any experience with this? Or any other solutions. Thanks.

As far as I'm aware, Verizon phones are not "locked" per se. They are CDMA devices, so do not use a SIM card, and their ESN number must be registered on the carriers network in order to work.
So, to get a Verizon Tab to work on another CDMA network, you'd need to ask the new carrier to register the device's ESN on their network. Often this is much easier said than done, since some carriers (notably Verizon I'm told) do not like to register "foreign" devices on their networks.
I've no idea which carrier you want to use a Tab on, but if it's not a CDMA network, the Verizon Tab is of no use to you.

Hey guys I'm not entirely sure if this is the right section to post this but any help would be appreciated. I have a galaxy s5 that my buddy sold me and i want to unlock it, but i called for an unlock code from us cellular, and they said i have to come to a corporate store to have them connect it to their software . I don't want to do this because it's 5 hours there one way. I don't have that much time seeing as how i work 60 hours a week .... is there anything you guys know of that i can do? :/ Any help would be appreciated! If you can try to keep it easy to*understand?
Im in the same situation. I have a US Cellular Galaxy S5 that i purchased online to unlock but i havent found an unlocking website or its only for international GSM unlock. I want a domestic unlock and I live in the middle of Arizona with no US Cellular stores.
Most unlock codes don't work on CDMA-locked devices/carriers (Verizon, US Cellular, Sprint) due to how differently CDMA phones ID themselves on a network - the SIM card is essentially only used for LTE, so a SIM unlock is useless. I haven't been able to find much hard information on it, but the process (as I understand it, someone else please correct me if wrong) involves the carrier a phone is locked to unlocking the phone, removing any codes which that carrier uses to ID the phone on the network, and handing it off to you. Think of it as a reverse provisioning.
For that reason, you're pretty much got to take the phone in. USCC doesn't want you to jump on the unlock fad and accidentally hose your phone for use on their network should you just be experimenting, so actually going in and talking to them provides a nice chance to make sure you know what you're doing and want to go through with it. I also don't think they've got the auto-unlock infrastracture in place (as opposed to auto provision).
Also, keep in mind - the CDMA S5s don't use full frequency bands like the GSM ones do. This will show you which ones the USCC one uses - http://www.gsmarena.com/samsung_galaxy_s5_cdma-6338.php - look for G900R4. You should be ok on AT&T/Cricket or T-Mobile but it looks like you'd be pretty well hosed on another CDMA carrier.
I'm so disappointed as Sprint just told me they won't allow me to activate my US997 unlocked G6 on their network. Was anyone able to overcome this with Sprint? Really wanted to keep this phone but don't want to switch carriers.
All,
I have an original TMobile, Galaxy S8, G950U. I unlocked it through TMobile and I purchased a Straight Talk BYOP kit from the local Wally-Mart, and put the AT&T SIM into my S8.
I know there are a number of guides out there, to do carrier switching. Trust me I have downloaded GBs worth of carrier firmware and combination firmware, eng boot, what have you. Nothing has worked as far as allowing me to carrier switch.
Here is my issue. The building where I work sucks for Tmobile. It is a hardened building and TMobile's signal does not penetrate. AT&T and Verizon work great. I unlocked my phone through TMobile and was able to flash the unlocked firmware on it. But, in theory, this did not enable all the AT&T radios, because I have an AT&T work phone and it works fine in the same spot, but my S8 cannot send or receive calls, in the exact same spot.
The problem is that I am on Bootloader V3 and I cannot for the life of me find an EngBoot with V3, so I can do a carrier switch and flash the AT&T modem. If someone has been able to do this, or if I just suck at searching, then please let me know, I'll be glad to take the hit.
So if anyone can point me the right direction for BLV3 carrier switches, I would greatly appreciate it!
Thanks all, for looking and trying to help.
I recently bought used Sprint Samsung Galaxy S7. It turned out the phone is locked to Sprint and is on bootloader v5. I called Sprint but they refused to unlock it even though it is paid in full because I am not the owner of the account that phone is associated with. I bought it from an electronics recycling company, so they cannot help with this. I would like to use it with a gsm carrier, like ATT or T-Mobile. What are my options here? Can the phone be unlocked by third-party? Even if unlocked, can the necessary bands and other settings be made available? Any hacks that trip KNOX are unfortunately not acceptable in my case (it seems putting U firmware with BL5 will trip KNOX).
IMEIGURUS.COM should have a carrier unlock for you. not saying its free.
That is fine but after it is unlocked would I be able to use it with t-mobile or att without issues? I read a lot about LTE frequencies locked, missing menus to set APNs, etc.
It is fine if the answer to my original question is to simply get rid of the phone. I am already considering this, as I naively thought that all it would need is a call to Sprint to unlock it and then flashing the U firmware.

There is a thread here about unlocking additional LTE bands.
