What is the 4G network and what are its benefits?
The 4G/LTE network is currently the most widely used mobile technology in Cuba. More than 50% of mobile users already browse using 4G, thanks to its significantly higher performance.
Compared to 3G, 4G offers:
Up to 10x faster connection speeds
Greater stability
Better performance for messaging apps, social networks, video calls, and web browsing
Requirements to connect to the 4G network in Cuba
To use Cubacel’s 4G network, two conditions must be met.
1. A compatible mobile phone
Your device must support LTE FDD Band 3 (1800 MHz).
Phones purchased outside Cuba may have limited band support depending on the country or carrier, so it’s important to check the device specifications before relying on 4G service.
2. A USIM card
Only USIM cards are compatible with the 4G/LTE network.
To verify your SIM type:
Send an SMS to 2266 with the text SIM
You will receive a response confirming whether your SIM supports 4G/LTE
How to check if your phone supports 4G
You can verify device compatibility by:
Sending an SMS to 2266 with the first 8 digits of your IMEI
The system will reply confirming whether your phone is compatible with LTE.
Visual confirmation
When mobile data is active and you are within coverage, the 4G or LTE icon should appear at the top of your screen.
