Messaging Apps in Cuba

WhatsApp is the most useful messaging app for coordinating with casas particulares, drivers, guides, restaurants, and tour operators. Verify the account before departure while the normal number can receive its setup code, enable two-step verification, add a recovery email, and keep the account on the original number when changing SIMs. A Cubacel SIM can provide local data and calls without requiring a WhatsApp number change. Save the accommodation, airport driver, airline, insurer, embassy or consulate, and emergency contacts both in the phone and on paper. Power failures can interrupt mobile towers and internet access, so a delivered message or live location is never guaranteed. Confirm critical pickups before a blackout, write down the address, and establish what to do if neither side can connect. Do not send a cash deposit or accept changed payment details solely because a familiar name or photo appears in chat. Verify through another published contact. Avoid forwarding rumors about protests, shortages, or flight status; check the airline and government advisory directly. Cuba's official emergency numbers are 104 for ambulance, 105 for fire, and 106 for police, but response and phone availability can be affected by the current crisis. WhatsApp calling does not replace those services. If internet access is blocked or restricted, a reputable VPN installed and tested before arrival may help in some cases, but no provider can guarantee service. The essential preparation is verified contacts and an offline fallback, not an assumption of continuous messaging.
