@SusanTr_2172922 The APN will need to be set to mob.asm.net. You do this from the router settings which you should be able to access from your browser by putting in the appropriate IP address for the router (in the manual from manufacturer)
Don't forget that you can only use up to 12Gb data for EU roaming - you would then need an EU data roaming pass for one or three days to continue. If outside EU, you will need to add credit to the account and price per Mb will be as per the Price Guide.https://cdn.smarty.co.uk/files/SMARTY-Price-Guide.pdf
