Ridiculously easy.
Jordan made its name as a hub for tech entrepreneurship in the region, and so almost everyone in Amman seems to either be fixated on their phone screens; some hijab-observing women have a phone literally tucked into their tightly wrapped headscarves. Getting online is ridiculously easy in Amman, literally from the moment you get off the plane
Queen Alia International Airport has free Wi-Fi that works throughout the terminals. Zain and Umniah, popular cellular service providers, have booths with helpful staffers just outside the Arrivals hall at the airport, and offer prepaid plans with 4G data services. You’ll need to present your passport to get a SIM card. Zain offers a package that includes a 4G data line, 4GB of data and 200 local text messages for around 13 Jordanian dinar (US$19) including the cost of the SIM. Remember to ask to include international dialing.
The WhatsApp messaging app is incredibly popular, so if you’d like to connect with people in Jordan, messaging or calling via WhatsApp is pretty much a guaranteed way of getting in touch. Most cafes, coffee shops, restaurants, and hotels offer free Wi-Fi, though Wi-Fi isn’t available at tourist sites in Amman, or hole-in-the-wall places.
