Staying connected in Cuba has always been a challenge, but thanks to ETECSA, the state-owned telecom operator, mobile services are now more accessible than ever. Whether you are a Cuban resident or planning a long-term stay, a prepaid SIM card is the most common way to access voice calls, SMS, and mobile internet. Below is a complete guide covering everything you need to know.
Basics of Cuban SIM Cards
- Operator: ETECSA, under the mobile brand Cubacel
