Need help carrier unlocking two phones - Android General

Okay, as the title said, I need advice on a program or software that will help me unlock two different phones.
They're both Sprint phones and They're not easy to unlock, I'm normally pretty good with these kinds of things but Sprints CDMA garbage is preventing me from prevailing.
The first phone is a Samsung Galaxy Note 5 running 6.0.1 (Marshmallow)
The second Phone is an LG G3 running 5.0.2 (Lollipop)
as i said they're Sprint phones but i need to unlock them so that I can switch over to T-Mobile
I'm not paying to get them unlocked because if i was going to i'd be better buying a new phone instead.
Any advice on how to do this or where to go that won't cost anything?
the help is very much appreciated, Thank you in advance.

[Q] att lg g2 unlock

hello, I'm basically new to this forum and I'm an amateur, so here my question. Can the 32 gig, att d80020 with the 4.4.2 kitkat update be unlocked? I've read in some places that it comes factory unlocked and there's a lot of people who say they can unlock it but turns out they cant. can someone help with a cheap method cause att sucks for their data plans and I want to switch to tmobile.

This might be the most ridiculous question ever...

Dont bash me I know this might come off as a ridiculous question to some but I have paid off my device through t-mobile and they unlocked it for me. Does this allow me to have more options with roms/etc.? I'm not quite sure what the unlock truly does for me other than I suppose I can take it to other carriers. However, does this include cdma carriers like sprint or just gsm? And I assume h850 roms would still be a bad idea correct? Any help or insight is greatly appreciated, Thanks!
This just means you can use your G5 with other carriers instead of just being locked to T-Mobile.
The unlock will last through wipes and ROM upgrades also, which is good to know. A different partition in the phone is used to trip the unlock which is not altered by system updates/wipes.

The SIM unlock means you can use it an any other GSM/WCDMA carrier (AT&T as well as some of the smaller ones like Cricket). You can not use it on CDMA carriers like Sprint or Verizon because the chips are fused to only allow GSM/WCDMA technologies. Sprint and Verizon use a CDMA fused chip and you can't us them on AT&T and T-Mobile, etc. There are a couple of types of "unlock". SIM unlock like you have, and bootloader unlock are most important. If you now unlock the bootloader you can root the device and then load custom ROMs to it. You can load H850 roms if it's been ported to H830 which there aren't any right now but will be soon. There is the fluence rom for H830 that you can load. I hope this helps.

adding on to everyone else, I have seen some phones go from VZW to TMO but there were so many issues with these devices it was a YMMV situation. The unlock through TMO is a carrier unlock, not a bootloader unlock. Your phone is worth more on craigslist/ebay now since it's unlocked at least.
Thanks for all the useful info. Been flashing and rooting for years but it's always nice to get assistance from all you smart people lol. Never really knew there was a difference between a bootloader unlock and a Sim unlock so learned something new. Thanks again for the insight!
There is ways to root and load customs Roms on some of the lg g5 models hg850 international version, but also the hg830 T-Mobile model as well now, and I believe there is a process for those who updated to 10d firmware before rooting to be able to do it now as well, so I would go check out the lg g5 fourms for that.

Straight Talk Samsung Galaxy S6 4G LTE (S907VL) Carrier lock?

There is a lot of info about the Samsung Galaxy S6 for other carriers but not so much for the Straight Talk Samsung Galaxy S6 (S907VL).
I'm interested in buying this phone but I'm not sure whether this device is carried locked and if so whether it's easy to unlock.
Besides that, does anyone know whether this phone supports overseas GSM bands?
Lastly I would like to know more about what kind of ROMs are flashable on this phone.
Any help would be greatly appreciated!
straight talk phones are sim locked and ST will not unlock them
I just picked this one up a couple days ago and so far I love it, but I've had no luck finding any info about this model (SM-S907VL) I'm mostly looking for root and maybe a custom recovery but I'm at a bit of a lose here
As far as the Sim unlock goes, I thought ST would only allow unlocks after a year of active service, but maybe but don't hold me to that
Need root and ability to use a rom that is upgraded to android 7

Look at the list of available Verizon devices, get their model numbers and then search to see which of those model numbers are rootable.
If you can use any unlocked device then just search for rootable devices that Verizon will allow in their BYOP program, if they allow unlocked devices then take your pick of any of rootable devices they allow on their network. You can even choose a device that is not only rootable but has custom ROMs available also.

[Help] Make Sprint / Freedom Pop Galaxy S7 Work on T-Mobile

My father recently lost his phone, and so I'm migrating his number to my t-mobile family plan. The only phone he has available is a Samsung Galaxy S7 that he purchased years ago to test with Freedom Pop. It's Sprint branded on boot up, but gives an invalid SIM with a t-mobile sim.
Model: SM-G930P
Software Version: G930PVPSBC TA1
Hardware version: Rev0.6
I've not had to be in the XDA scene for over 6 years since I'd started using Nexus / Pixel phones, so I've let alot of my knowledge slip; but I'm at least capable if pointed in the right direction.
Can someone please help provide me with a checklist of what I need to do to get this phone functional on T-Mobile? If I at least know what I have to do, I can figure out the rest...but given the time crunch of him without a phone and in need for medical reasons, I'm in a bit of a rush and can't study this model phone enough to know what all is necessary.
I'm assuming I need to unlock it, but I've never had to unlock a phone...they've all just worked between carriers for me. I tried contacting Sprint, but they wouldn't unlock it without an account. I tried some shady sites, but they seem expensive and don't understand why needed.
I'm hoping all I need to do is just figure out root access, get a recovery mode installed, flash a T-Mobile or other firmware, and bam...but I really am not sure. Any immediate help would be greatly appreciated!!
I tried contacting Sprint to unlock the phone, but they required I have a Sprint number with them. Seems odd, considering it's a federal law for unlocking now...
Well, I went ahead and just flashed the SM-G930T firmware on my Samsung Galaxy S7....and got an invalid SIM error.
Tried contacting T-Mobile, they went through a bunch and ended up saying Sprint would need to unlock it.
So now I'm stuck...and have no idea what to do next. Seems like I need to setup a Sprint account, get a Sprint number, unlock my phone, and cancel the service? That seems insane...
Was going to do a three way call with Sprint and T-Mobile, and hope somehow something could be sorted. Considering T-Mobile owns Sprint now...this just seems like hassle.
Any advice from anyone would be appreciated!
