You can make international calls with Cube Móvil in the same way as other mobile networks or fixed line phones.

To call an international number from Mexico, you must enter: the international call prefix (+), the country dialling code, and then the area code and/or subscriber number.

For example, to call a mobile number in the United Kingdom from Spain, you would enter: the international call prefix (00 or +) + the country dialling code (44) + the subscriber number (xxxx xxxxxx). All together that’s: +44 xxxx xxxxxx

Note: most premium voice and text services in other countries cannot be reached from a mobile phone service when calling from outside that country.
