Regarding 4G, I very often while at home only have one bar showing for cell coverage, infact as I type this it changes from no bars to one, so I'm hoping that when I get the second new sim that it gives me better quality cell phone signal than my current sim.
I asked for MMS to be switched off as once I was charged when I sent a normal text and the virgin system incorrectly thought it included multi media, and as I don't use the stock SMS app for none other than text only I asked for MMS to be turned off so that incident wouldn't happen again.
I think they key thing is that the new Authentication type is CHAP, my new SIM would not allow the old type of PAP to be saved. When I entered the APN details as specified by teabag my phone sprung to life. Here's my APN settings now:
