N97 cannot make outgoing calls. Only prompted to "not allowed"

hi there!

if you cannot make ANY outgoing calls at all, first thing to check would be the load/minutes on your phone. if you're in a post paid subscription, better to call your telco first if they have issues with the network thats why you cant make outbound calls.

if you made some changes with the phone's settings too, the call settings may have been changed aswell. try resetting the phone's settings if the first option didnt work.

if you cannot call out to some number only, please check for the numbers of those contacts, there may be additional characters on the number your dialling (# or +), check on area codes too.

all of those three will have the error "not allowed". post back with full info on the problem if its still not working after trying those mentioned above! =)
