Do you have a postpaid plan? Prepaid service can not roam internationally. Do you have international roaming enabled on your line? ATT does not provide service in the Middle East. Service comes from foreign carriers. If you are in a location where there is no service, there is nothing that can be done.

Your prepaid service does not work outside the US. If your phone is unlocked, you can purchase a local SIM card but there isn't anything ATT can do for you.
