ETECSA has offered 3G mobile internet since December 2018 and added 4G/LTE service in October 2019.
To activate the mobile data you need to know a few things:
You must have a cell phone that connects to 3G on the 900Hz band and 4G on the 1800Hz band. In phones sold by international companies, this detail needs to be reviewed, because companies often restrict the spectrum of bands on the phone.
How to activate Cubacel's Internet?
If you meet these requirements, you are very close to using Whatsapp in Cuba 😉
Just dial *133#
In the menu, you have two options to purchase mobile data, Data or Plans (Data + Voice + SMS).
Option Data
There you will find 4 options to activate the Internet.
Either of these options allows you to use messaging apps and surf the web, but it's good to keep in mind that buying LTE packages is much cheaper.
Remember: Option 4 LTE Packs are only available to 4G users.
Option Plans (Data + Voice + SMS)
This offer has become the preferred one for 4G network users, with cheaper prices in relation to the amount of megabytes / gigabytes purchased.
Mixed plans have also become more popular with 3G-only users, who add this option to the Pay-as-you-go and Mailbag as the only ones available to them in Data.
