i have this problem before, when i was oversea and using the local sim card, sometimes this error will appear. but when i switch back to my original sim card, no more such error, so i think its the sim card problem, not saying your sim card have problem or something, maybe its about the conpatibility or something?

It has been a couple of months and no solution to the error  "sim not allowed mm#3". what is Sony Ericsson doing about this!

I'm having second thought now why i bought a sony ericsson phone...get this fixed with a new software!
