AIRALO the Esim card for Cuba - To test. After some research it seems Airalo works in Varadero, but I'm not sure.
I found the information on the tripadvisor website
Here is someone's comment from February 21, 2024
Airalo is highly recommended. This is convenient for short connections when necessary. It's $9.50 for 1 GB valid for 7 days. It activates when you enter the coverage area.
On their website it indicates CAYOS but comments say that it works in Varadero, this would need to be validated
