I've been happily using NOMI prepaid for a couple of months since Feb 2011. Now, all of a sudden, I cannot place any calls anymore (I do have lots of credit). After dialling only some beeps and total cut off. No calls anywhere in the world are working - and no, I don't have any diverts on.

I cannot even check my balance anymore: "Requesting... RESULT UNKNOWN." :(

Nothing working, that is. What has happened? :(
