In general, you enter a number to text exactly the same way you would dial the same number for a voice call from your mobile phone. For example, if you are in (fictional) area code 999, sending a text to (999) 555-0123, you might enter the number as 555-0123, 999-555-0123, or even +1 999 555 0123 (international format).
