Yes. Smart sells its Traveller SIM at its booth in every international airport in Cambodia, and Smart eSIM can be bought in the SmartNas app, on its website or in a Smart Shop. Either way you need ID: Cambodia's telecom regulator requires operators to check valid identification before activating any SIM, so the eSIM purchase asks you to scan your passport and complete a face check.
Usually not, but there is one case to know. Cambodia's immigration department uses the FPCS app to register where foreigners stay. Hotels, guesthouses and landlords register you themselves, but if you stay with friends or family you must register yourself, and the UK government notes that a Cambodian phone number is needed for the registration to be valid. Skipping it may stop you extending your visa. A data-only eSIM will not give you that number.
Not everywhere. The UK government's travel advice says Cambodia's main cities and towns have good Wi-Fi and mobile networks, but many islands and remote areas are not well covered. Before taking a boat out to the islands or heading deep into the countryside, download offline maps and your booking details, and let friends or family know you may be out of contact for a while.
Yes. Install your eSIM before departure; once you land, simply enable data roaming to connect instantly at the airport.
