I cannot input or save any APN details and my mobile data does not work. Please help!

Hello,

I have bought an unlocked samsung galaxy s5. It seems it is a phone from the USA, previously on Sprint network. I am using a Brazilian local carrier's sim card which is realtively new (4 months old). The phone is a G900P.04 running android 6.0 Marshmallow.
The mobile data is not working. Calls to the phone work fine, but no data.

I am trying to input the APN for my network here in Brazil (Vivo).
Every time I input the APN settings, and select 'save', nothing happens and the APN list is still empty. I have clicked 'reset to default' already. The list is empty - there are no pre-existing APNs.

I read somewhere else that it could be that the MCC or MNC code could be causing a problem, as the phone may think it is still in the USA. I don't know what that means.

Any help would be much appreciated!

Thanks

It means that you have to have your phone unlocked..if you don't unlock it you can't use the data in any network other than Sprint..
