What is the exact model number of your S10?
Welcome to Android Central! You need to make sure your phone supports GiffGaff's LTE bands, which are 1, 3, 8, 20, and 40: https://www.4g.co.uk/giffgaff-4g-coverage-network-summary/
Also, make sure your APN settings are correct for GiffGaff:

SMG937F
Is there a carrier store where OP go and let them configure the APN?Thanks. I think you mean SMG973F but that's good as it's the international model which is aimed at us in the UK. Check out B.Diddy's post and if everything matches you may need to contact GiffGaff as the sim may be faulty.

When you put the sim it didn't populate a APN automatically?Unfortunately carriers don't have store but is done via online
