I have a project that has been using Fona 800's in the UK, these have been using the giffgaff (O2) network for the last few months, I am struggling with poor reception so I have tried using a VOXI (Vodafone) and EE sims, both work in an S20 when locked into 2G mode. When trying the sim in the FONA with the FONAtest sketch, only the giffgaff sim can enable GPRS and read a webpage. This does take a few attempts but then works fine.
I get this initially..
