How to split text that comes from String

[Arthur_Ziganshin]

Hello, need your help friends.
how can i split phone numbers via string
The phone number comes intact for example 0550000000
The first 3 digits is code area.
I need to divide the number to separate the code area from the rest of the number

like in the picture, if the first 3 will choose the 055 from the dropdown then it will fill the next value of the number
