Mobile Service in Cuba
ETECSA / Cubacel (State Monopoly)
ETECSA (Empresa de Telecomunicaciones de Cuba S.A.) is Cuba's sole telecommunications company and operates the only mobile network under the brand name Cubacel. There are no competing carriers. ETECSA holds a 100% market share for all mobile, landline, and internet services in Cuba.
| Service | Prefix | Network Type | Market Share |
|---|---|---|---|
| Cubacel Mobile | 5 2XX, 5 3XX, 5 4XX, 5 8XX | 3G / 4G LTE | 100% |
| Nauta (Internet) | N/A | WiFi Hotspots / Home DSL | 100% |
| ETECSA Landline | Area code based | PSTN / Copper | 100% |
Important: Cuba launched 4G LTE service in late 2023, but coverage remains concentrated in Havana and major cities. Mobile data is expensive by local standards, and WiFi hotspots at public parks and hotels remain commonly used for internet access.

Troubleshooting Common Issues
Call not connecting to Cuba
Cuba's telephone infrastructure is limited. During peak hours or after natural disasters, the network can become congested. Try calling during off-peak hours (early morning or late evening Cuba time). Also verify you are using the correct area code - Havana uses the single-digit code 7, not 07.
VoIP calls blocked or poor quality
Cuba has historically restricted VoIP services. While some VoIP calls go through, they may be blocked or experience severe quality issues. If your VoIP call is not connecting, try calling the landline number instead of the mobile number, as landline connections tend to be more reliable for international calls.
ETECSA monopoly limitations
Since ETECSA is the sole provider, there is no carrier choice in Cuba. If you are having trouble reaching a Cubacel mobile, the person may be in an area without coverage (especially rural areas), their prepaid balance may have expired, or the network may be temporarily overloaded.
Internet and data connectivity issues
Internet access in Cuba is still limited and expensive. Many Cubans rely on public WiFi hotspots in parks and plazas. If you are trying to reach someone via WhatsApp or IMO, they may only be reachable when near a WiFi hotspot. SMS or a direct phone call may be more reliable.
Getting a "number not in service" error
Cuban phone numbers have changed format over the years. Ensure you are dialing +53 followed by the area code and local number. Havana numbers are +53 7 + 7 digits. Provincial numbers are +53 + 2-digit area code + 6 digits. Mobile numbers are +53 5 + 7 digits. If the number has fewer digits, it may be an old format that is no longer valid.
