I am here on a visit visa (Waiting to start work) and I have a bank account, mobile and a driving license.  You just need to make sure you renew them (Visit visa 100 riyals for extra month - upto max 3 months and driving license to start is 250 riyals then 100 to renew every month) until all your paper work is complete.  You will need a letter from your sponsor for the license.  Good luck.
