What you may find is that Samsung apply a region lock to their phones @NV-TECH
This is to try and curb grey imports.
What really needs to happen is that a person makes a few calls totalling 10 minutes into country of origin using a local sim card and calling a local telephone number to remove this lock.
If.you contact the Samsung Support Department of the country of origin I.e the UK they maybe able to remotely remove the region lock.
To add 》If the phones were bought directly from Samsung they should be unlocked to all networks.
If they were not then you would need to check from where they were purchased from to make sure they listed them as unlocked to all networks.
If a phone isn't unlocked to all networks they wouldn't accept another networks sim card and would need to be unlocked to all networks by the network they are currently locked to.
