I have a personal mobile router sometimes called a MiFi, I use when away, just in case of no or bad internet where I might be staying.
I bought a giffgaff sim, that I thought would suit my needs.
I can’t get internet signal. My iPad that I use recognised the device. There’s a tick against the device name but no internet signal bars.
I use a vpn. This sim works if I turn vpn off. Not when it’s on.
I’ve used other makes of sim in the device EE Vodafone etc. Never had issues. Even with vpn on . I’ve sent a query to giffgaff but haven’t had a reply. Thanks for any info
