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

Did You unlock GSM on Your phone?

I too have an r970 from USCC. I too went to the corp location to have them courier unlock the phone. I have installed "OctOS" rom specific to this device. I have put a t-mobile sim card in the phone and get intermittent "LTE" but cannot make or receive calls. Is there anyone who has any info on this subject?

[Q] question

hello , i am asking if there is a way to sim unlock for galaxy s4 US cellular sch r-970 ? and how can i do it ? iam from egypt and brought samsung galaxy s4 us cellular sch r-970 from US and its refuses my sim how can i solve this problem ?
thanks for all and wish to help me in that

Hey mate!
Many people have this sort of issue when they purchase devices overseas.
You can try and find a reliable online unlocking service for your device (I have personally never done it online so I don't know any - Remember research on the site before paying them, there's lots of scam sites).
Most appropriate one would be a local store. A place that deals with smartphone's and ask then to service unlock your phone.

Hit thanks if the post helped you.

nop it isn't the phone don't wanna to dial any codes

Remove simlock

Hi xda, it's been a while since I've been here and looking around has me scratching my head a little.
Anyway I have just purchased a galaxy s6 from eBay foolishly thinking it would be easy to remove the simlock but after a little reading I'm beginning to think I may have made a mistake. I'm not sure what network the phone is locked to as I have not yet received it and the listing states in the title O2 but the description says Vodafone, all I know is the model begins G920F. I thought maybe rooting and flashing a stock firmware would remove the simlock but after reading it looks like this is not the case. I then read also about "tripping knox" which sounds like something I don't want to be doing.
Root is probably something I will be looking to do in the future but not essential right now but I would be very grateful if somebody could tell me the best way to go about putting my virgin sim in this phone.
Please help
Thanks Peter.

I thought the 920F is the facotry unlocked international version so any sim would work.
When are you receiving this? Where are you trying to make this work.

Most European providers don't simlock, so you will most likely just have a provider rom, they are easy to replace with a generic stock rom

He is sending the phone out first class tomorrow so I'll report back after I have received it. I'll be using it in the UK, hopefully I'll get lucky and just be able to use it as soon as I get it. Thanks for the replies people.

Try buying an unlock code from one of the many reputable online unlockers.

I am also in the same boat. I bought samsung galaxy s6 sm-g920f model from malaysia and now when I insert indian sim its say its locked and asking for unlock code. I am just worried now. i am thinking if i can flash stock indian firmware sm-g920i to realease the lock.

no you need an unlock code

Well I received the phone today and it seems I don't have to worry about the simlock as it's a bloody counterfeit!!! Grrrrrrrrrr, in the middle of a dispute atm but hopefully I'll receive a refund. Anybody that wants to help please see this thread...

[URGENT] At&t unlocked software updated ?

Hey guys,
I am thinking to buy a Galaxy S6 At&t unlocked version from the local shop so there's no chance to go to the BestBuy to update the phone because they don't operate in my country and the same thing goes to Samsung, Samsung has a sales offices in my country, not the help centers. I want to know If I buy that phone, I can get the latest nougat update from At&t or If I flash the latest At&t ROM from the SamMobile, does this affect my unlocked phone? Like after flashing I can still use any carrier network?
Hope you got it what I'm trying to say.
Edit: is Smart Switch will help me to update to the latest firmware?

im 90% sure you can use any sim if its already unlocked on any other carriers firmware but i know some of the U.S variants are locked down to carrier specific

My friend owns the same phone and He can use any network sim but that was not the question. I want to know about the update, If I manually flash the firmware will it break the unlocked functionality as the model firmware are only specific for the network.

no it wont break it
