I get phone number you have dialed is temporarily unavailable

I tried calling my friend who is visiting and got the above message, I called the hotel where he was staying and got the same message.

I used my girlfriends phone and was able to call both numbers

I can call other number with my phone and it works fine.

Any ideas how to fix.
