How to check if you can activate mobile data
Before reviewing your data consumption, it’s important to confirm that your phone and SIM card can connect to Cubacel’s 3G or 4G/LTE networks.
1. Check device compatibility
Dial *#06# to display your phone’s IMEI.
Send a free SMS to 2266 with the first 8 digits of your IMEI.
You will receive a message confirming whether your device is compatible with mobile data services.
Alternative method (faster):
Dial *222*468# to get the same information instantly.
2. Check if your SIM supports 4G/LTE
Send an SMS to 2266 with the text SIM.
You will be notified if your SIM is a USIM, which is required for 4G/LTE.
If confirmed, send another SMS to 2266 with the text LTE.
You should receive a message similar to:
“ETECSA informs: You can use 4G/LTE when you are in a coverage area. Configure your phone. For more information, contact 52642266.”
