Saudi Arabia is covered by our multi-country plans, which currently connect to Mobily and Zain in Saudi Arabia.
Every plan card on our Saudi Arabia eSIM page lists the exact network that plan connects to, so check it before you buy if a specific operator matters to you. After you land, your phone joins the plan's network automatically; you do not need to choose it by hand. If you see no signal, make sure data roaming is turned on for the eSIM line.
