Giffgaff SIM on BlackBerry Passport?

Is anyone running giffgaff on their passport?

I've run my blackberry on it previously and 4G works fine

My problem is that I have giffgaff on my curve and leap but when I install the nano Sim into my passport it just shows as not connected.
If I then take the nano Sim and mount it as a micro into my Leap it works fine.
I am at a loss.

Using giffgaff in my Passport without any issues. Try new giffgaff sim card if it helps.

Using giffgaff on my 9900 (with BIS) and regularly swap the SIM into my Q10 where 4G works with no problems. Have you tried any other SIM in your Passport?
