7290 shows an error

My Blackberry 7290 shows the following error after I have dialed ##121# for checking my remaining value on my SIM card.


"Supplimentary service error: Unknown alphabet."


How can I solve it?

Re: 7290 shows an error

If this is the only time the error occurs, then I would probably check with the service provider as the SIM card is a separate piece from the BlackBerry or there is a password that has been incorrectly placed on the BlackBerry.  Let us know how it works out.
