Would like the ability to insert country code in phone numbers

Hi, I need your help, I´ve to put the fiel cellphone into my form, let me tell you that in Argentina we use: the area code + the numer 15 + the telephone number (Ex. 011-15-52392030)But in my form I only need the code area and the cellphone number without the number 15. That is why i wpukd like to write the numer 15 out of the field. 

I send you a jpg explaining you what I need.

Do yuo have spanish assistance?

Thankyou.

For this, the only thing I can recommend would be to use the full phone number field including the country code:

If you need to automatically insert the 15 in to the number, that would need to be done conditionally and would likely require two separate fields instead of one.  If that is the case, let us know and we can show how that is done as well.

I made a demo for you:

It uses this CSS code:

.phone-separate:after {
    content : "15-";
}
