It's very strange that all you are validating about a phone number is its length. Why are you not using a regex to ensure that it's all numbers, dashes, etc., of the correct format?

but on button click i can save the value in textbox even if it is less than 10
this is what i do:
function ValidatePhone() {
debugger;
var isSuccess = false;
var phoneVal = $("#Mobile").val();
phoneVal = phoneVal.value;
var numbers = phoneVal.split("").length;
if (10 <= numbers) {
alert("SUCCESS");
isSuccess = true;
}
else {
alert("check number");
isSuccess = false;
}
return isSuccess;
}

<%: Html.TextBoxFor(model => model.Mobile, new { maxlength = 10, style = "width:145px", @onblur = "return ValidatePhone()" })%>
