On my last visit to Saudi (September 07) i managed to get a brand new ‘Mobily’ pre paid SIM card from a cleaner in the immigrations hall. He had a stack of them.

It cost me 120 saudi riyals which is about $30 US. It came with 100 riyals of credit.

I slipped it in my phone and it was activated immediately. This is useful for calling your local contacts and giving to people back home etc.

The SIM roams internationally too.
