we are a family with 4 Giff Gaff Sims working in our phones .. very well
we are going to purchase a Portable Wifi Router unlocked as we are travelling to Europe with no wifi where we are staying but ok 4G coverage
Can we purchase a sim from Giff Gaff to go into the portable router?
I've looked and cant quite find how to do it as we have no 'mobile number' for the device
Any guidance would be appreciated
