Does anyone know why I get this message?

UPDATE: I removed it and registered it again and it is now working. Thanks everyone

I purchased this on the UK young person's store but this message pops up. Any ideas?

Give it a week or two. If still with that message remove and reregister the device

Hi and welcome to the community.

It might take some time to register.

Can you also provide the screenshot of "service provider software version" ?
Settings > about phone > software information > service provider software version

Here you go

Possibly a silly question, was it new when you bought it?

[Wonderstruckmochi]

Yes, I got it from the samsung young person store

Ok well you have a UK version and I'm assuming it is a UK SIM in the device.

I would think about returning it for replacement before the 14 days are up.

Just to ask...do you use a VPN on your phone ? If so then try disabling it and try again.
