Your last & only solution if you want to use your phone, it's to root your device.
Because it's your radio which is bad. Your baseband is for only USA and not for Greece or World West Europe (WWE)
You need to root your device and change for an European Baseband.
That's why you need to know what exactly your device:
Go to settings => About =>
Phone identity
(you will see model number, and lot of infos that you will need write somewhere for giving on your next post)
Software information
(remember these infos)
and finally click "More"
You will see your baseband and more infos that you need to give also.
Give me your model number and your device serial number, and I'll give you the good way for searching

I've got a bad news for you because you cannot unlock your sim card.
In fact your phone is only use for US cellular (CDMA) not European (GSM)
Uscc is not a gsm phone the sim card slot is used for thw 4g service the phone itself is cdma
If you use "search all forums" just above and type:
Code:
Samsung galaxy s4 sch-r970 unlock
you will find a lot of posts about this subject but with all time same answer: You CANNOT
Sorry for this bad news.
Good luck

Honestly, I'd say to factory reset and Odin your correct version firmware. That way the firmware will be compatible with your Sim and Network.
Oh ya. Try to stick to the firmware that belong on the phone.... LOL. Let troubles that way

What carrier? Did you change the APN to your carriers? If not, that's your problem.

Yeah already try that. I live in Chile so I have a foreing carrier.
I think it has something to do with being a verizon phone in a different country.
There still no way to root my phone with android 5.0.1 ?

6.0.1 Verizon S6 on T-Mobile?

Hey guys, so I recently found myself the owner of a Verizon S6 that my dad found on the bus when he was out near Delaware. I thought it would be an awesome addition and that I'd be able to use it on T-Mobile, I've done it before, why not on the S6? Well, for some reason unlike the Verizon S3 and S5 I've used with my T-Mobile Sim, the S6 has been very stubborn. I've tried researching online but have found mixed answers. From what I've read since the posts were kind've old, the S6 could easily be switched to T-Mobile when it was on Lollipop with a simple tweak of the APN settings. Since the marshmallow update was pretty recent, I've tried time and time again with all of T-Mobile's APN's and I simply cannot get it to work. Does anyone have any insight on this? Is it simply because its on 6.0.1?
Some info on what happens:
When I insert the SIM and power on, it simply says "This is not a Verizon Sim" with no service whatsoever and "Emergency Calls Only"
Any changing of the APN has no effect, switching between LTE/CDMA, LTE/GSM/UTMS, and GLOBAL does nothing.
Any help would be greatly appreciated, thank you in advance!

Are you rooted? If not how am I able to downgrade? Is it the usual ODIN method?

On MM no Root, I just put the Sim card in and added APN. Maybe the phone is blocked reported lost?

SM-G900F but on recovery mode 900V - what did i buy?

I bought a few months ago SGS 5 (allegedly) SM-900F, it has a firmware (Baseband version - G900FXXU1GPE1) and the imei pages tells the same thing - it's 900F, but the problem is after 2 months from buying I could not send an sms from my UK GiffGaff number - i could call or use data. I tried many things but sms still does not work. At the begining I colund't send sms only from stock app but maybe 3 weeks later any apps from google play said the same thing "review the message and try again". I wanted to update firmware -G900FXXS1CQD1_G900FOXA1CPJ6_G900FXXS1CQAV_HOME.tar.md5 but in the recovery mode it says SM-900V so I'm so confused, how it's possible and what should I do in order to properly use the phone - call+SMS+data usage (4g)
Should I install G-900V firmware? Would it help? The ebay seller is a conman and I cannot even open a dispute beacuse it's too late now. It is a F***ing joke.
I know its USA Verizon phone but I live in the UK and have Giffgaff sim card.
Please help me with this one.

The G900F (International Variant) can be installed on the G900V (U.S. Verizon Variant).
If your device reflects the G900V on the Odin Download Screen, then that's what you have.
Typically when this happens is because someone had the Verizon Variant and couldn't use it because of where they lived and had to install the International Variant in order to use the device.
Nothing wrong with a G900F on a G900V but, I can't state on what to do because I've never done this before.
Here's just a few threads discussing this same thing.
