Block Cell Phone Signals in Cuba – Frequencies to Cover

In order to block mobile phone signals in Cuba, it is essential to understand the frequencies used by the country's main network suppliers. In Cuba, the main mobile network operators are Cubacel, belonging to the state company Etecsa (Empresa de Telecomunicaciones de Cuba S.A.), and Movistar, a subsidiary of the Spanish company Telefónica.

To make an effective blocking of mobile telephony signals, it is necessary to cover the frequencies used by these operators. In general, mobile telephony networks use specific frequency bands for communication between mobile phones and transmission towers. In Cuba, the main frequencies used by Cubacel and Movistar are as follows:

Cubacel (Etecsa):

• GSM band 900: 900 MHz
• GSM strip 1800: 1800 MHz
• UMTS band 2100: 2100 MHz
• LTE Band 1800: 1800 MHz
• LTE 2600 strip: 2600 MHz

Movistar (Telefónica):

• GSM band 900: 900 MHz
• GSM strip 1800: 1800 MHz
• UMTS band 2100: 2100 MHz
• LTE Band 1800: 1800 MHz
• LTE 2600 strip: 2600 MHz

To effectively block mobile phone signals in Cuba, it is recommended to cover the frequency bands mentioned above. This will prevent mobile phones from connecting to the transmission towers and will thus interrupt mobile communications.

It is important to note that blocking mobile telephony signals may be subject to legal and regulatory restrictions in certain countries. However, this article focuses only on the frequencies to be covered to achieve this technical objective.

In conclusion, to block mobile phone signals in Cuba, it is necessary to cover the frequency bands used by the main network suppliers, including Cubacel (ETECSA) and Movistar.
