Mobian Mobile Data Doesn't Work

[dukla2000]

Been using Mobian for a few days on a couple of different phones and with different SIM cards. Yet I have been completely unable to get mobile data to work at all. I have the icons 2G, 3G, 4G etc but there is never an actual data connection, yet from what I have read it should be working?

I am not sure if it is because the SIM cards that I am using are from piggy back networks - GiffGaff and Virgin Mobile in the UK - or whether there is some setting or set up that I am missing. Both SIM cards work in both phones and have data connections using UBPorts, this problem only occurs in Mobian.

I have tried setting up the APNs using the correct settings multiple times, with no luck whatsoever. Is there another step that I am missing?

I had so much grief with Virgin (UK) that I swapped my contract to 3!

Yup it definitely seems related to MVNO, somewhere there is another thread about an MVNO in the USA causing pain. With Virgin I could get a data connection after playing with APN settings (all goto.virginmobile.uk) and rebooting repeatedly in a high strength signal area after about an hour. In a low strength signal area I got a data connection about once in 3 weeks (this was during strong lockdown!) With 3 I just never have a problem.
