Data is cheap and easy. There is one restriction that catches people out.
A local SIM is the cheapest option by a wide margin. Vodafone, Orange and Etisalat all have desks in the arrivals hall at Hurghada and Cairo, a tourist package with 20–40 GB costs a few euros, and you need your passport to register — this is a legal requirement, not a formality.

An eSIM bought before you travel is the convenient alternative, slightly more expensive, and it works the moment you land with no queue and no passport. If your phone supports it, this is the low-friction choice.
Coverage is good along the coast and in the Nile valley, and patchy to non-existent in the deep desert — worth knowing before relying on maps for a safari.

The restriction: voice and video calls over WhatsApp, Messenger and FaceTime are blocked on Egyptian networks. Text and voice notes work normally, but a call will fail. A VPN restores it, and most visitors who need to call home install one before arriving. Hotel wifi is often subject to the same block.
