Hello all,

I recently changed mobile networks. Unfortunately, I can't seem to get any MMS messages to send - they show as sending for a few minutes and eventually fail.

I suspect the problem might be with the APN settings - my current mobile network is Superdrug Mobile, an MVNO using 3's network. The reason I mention this is that the SIM card's default settings are all labelled 3 and use the three.co.uk APN, apart from 3 Modem which uses 3internet, while my network gives these settings which use the superdrug.net APN - all the other settings are the same between this link and the default ones. Enabling only the MMS-only one and changing them all to example.com both have no impact on internet access, which still works. The changes show up in the APN settings but seem to have no impact outside of that.
