The ETravelSim Jordan eSIM works at Petra's main entrance, the visitor center, and across most of the archaeological site on the Zain 4G/LTE network. Signal can drop in deeper sections of the Siq canyon and around the Treasury when crowds are heavy, which is normal for every Jordanian carrier. Download offline Google Maps and the Petra route before you go in, and save tickets and confirmations to your phone for the parts where signal dips.
