Some of the instructions on the website do not work.
These instructions have worked in all cases so read and follow them carefully to get going:
If it still doesn't work then go back and start again as you almost certainly have done something wrong.
Hope this helps.
Well all I was saying was that those instructions have always worked for others and where they did not was because people did not read/follow them correctly and made some mistake when applying them.
I still think that this is the problem here.
I don't know why 48 support are telling you to change the MCC/MNC settings from 272/11 because that makes absolutely no sense to me.
