You can use the same regex/replace logic you have suggested.

html

Mobile:
Landline:

jquery

$("#mobile").blur(function(){
    var mobile_ele = $("#mobile");
    var mobileNum = mobile_ele.val();
    var formattedNum = mobileNum.replace(/(\d{2})(\d{3})(\d{3})/g,"04$1 $2 $3");
    mobile_ele.val(formattedNum);
});
$("#landline").blur(function(){
    var landline_ele = $("#landline");
    var landlineNum = mobile_ele.val();
    var formattedNum = landlineNum.replace(/(\d{2})(\d{4})(\d{4})/g,"($1) $2 $3");
    mobile_ele.val(formattedNum);
});
