not allowed to dial i486
 

This problem must be already posted here and I am very sorry i cannot find the thread. But this phone is driving me crazy. How do I solve the not allowed to dial message on a Sciphone i486? The phone worked fine when it arrived but after I got the wlan to work, I could not dial out anymore. I have put the simm in another phone and it works so I must have reset something in the phone. I have found advice on other sites that almost works and the last thing I was told was to reformat the phone but I don't know how to do that either. If anybody has beaten this problem, please let me know.
