Installed the hat on a Pi400 and have attached antenna. Tried a variety of sim cards (giffgaff and sky) but only get a solid green light. Tutorial suggests it should be blinking.

AT command in minicom says OK but nothing else works

The APN for giffgaff is [giffgaff.com](http://giffgaff.com), username g and password p!!

But I’ve given up bashing head against wall here and have ordered some of the 1NCE Sims that were being supplied for free. Hopefully the clipper getting started guide will then work!
