Issue with country code

Hi, as we know, in the plugin configuration we must set the country code, in my case, 53. If the customer enters the number 55######, the plugin handles the message for +53 55###### and it’s correct. However, if the number begins with 53 instead of 55 the plugin shortens the resulting number and the message does not arrive like the following example:

If the customer enters the number 5350####, the plugin handles the message for +53 50####, and the notification never reaches the client because the number is wrong.
