Is it possible to create an input field that sets the default input character set to numbers on a mobile phone (so the NUMERICAL KEYBOARD POPS UP)?
For example to make it easier type in a telephone number into a HTML form.

It is possible to limit entry on a "mobile phone" The mobile phone form entry uses 

<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">

input here can be limited using format="*N"

To make inputing numbers easier, use <input type="number">. To make entering phone numbers easier, use <input type="tel">. Not all phone will support them, but the iPhone at least will give you a numeric keypad by default instead of the normal keyboard. See the spec and Dive Into HTML5 for more information.

Watch out the limitations in entering periods and commas in such input fields: https://mcmap.net/q/196413/-html5-input-box-with-type-quot-number-quot-does-not-accept-comma-in-chrome-browser/1066234 – Christianson

You can use <input type='tel'>. This is a new HTML5 feature. Older browsers will simply default to a text input field.

So you can use either type="tel" or type="numbers".

The difference is that one tries to bring up your phone dial keyboard and other simply switches to the numbers input of your mobile keyboard.

Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . Code example:

<!doctype html>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Input Key Filter Test</title>
	<meta name="author" content="Andrej Hristoliubov [email protected]">
	<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
	
	<!-- For compatibility of IE browser with audio element in the beep() function.

<body>

	Please type a phone number in the +**(***)***-**-** format. Example: +1(23)456-78-90
	<br/>
	<input id="PhoneNumber" value="+()--">
	<script>
		function getArrayPhoneNumber(value){

				value = document.getElementById("PhoneNumber").value;
			return value.match(/^(\+?\d*)\((\d*)\)(\d*)-?(\d*)-?(\d*)$/);
		}
		
		function getPhoneNumber(){
			var arrayPhoneNumber = getArrayPhoneNumber();
			if(!arrayPhoneNumber)
				return "";
				
			var phoneNumber = arrayPhoneNumber[1] + arrayPhoneNumber[2] + arrayPhoneNumber[3] + arrayPhoneNumber[4] + arrayPhoneNumber[5];
			return phoneNumber;
		}
		
		inputKeyFilter.Create("PhoneNumber", function(event){//onChange event
				inputKeyFilter.RemoveMyTooltip();
				
				var arrayPhoneNumber = getArrayPhoneNumber();
				if(!arrayPhoneNumber || (arrayPhoneNumber.length != 6)){
					document.getElementById("NewPhoneNumber").innerHTML = "Incorrect format of the phone number";
					return;
				}
				
				var elementNewPhoneNumber = document.getElementById("NewPhoneNumber");
				var phoneNumber = getPhoneNumber();

				elementNewPhoneNumber.innerHTML = phoneNumber;

					inputKeyFilter.TextAdd(isRussian() ?
							"Недопустимый формат телефонного номера. Например: +1(234)56-78-90"
							: "Incorrect format of the phone number. Example: +1(234)56-78-90"
						, elementInput);
					if(elementInput.value == "")
						elementInput.value = elementInput.defaultValue;
					return false;
				}
				return true;
			}
			
			//onblur event. Use this function if you want set focus to the input element again if input value is NaN. (empty or invalid)
			, function(event){ inputKeyFilter.isNaN(parseInt(getPhoneNumber()), this); }
		);
	</script>
	 New phone number: <span id="NewPhoneNumber"></span>
</body>
</html>

Here's an example with Javascript. This will only allow numbers from the numpad/numbers on top of the keypad, and formatters (shift/backspace/etc). You may also consider adding a setTimeout(), with a couple seconds timeout, for the onchange event to check in case someone pastes non numbers into the field as well as server side validation.

Example

for my testing of "you can use either type="tel" or type="numbers"." on iPhone type="tel" brings up the numbers only keypad (like phone) and type="numbers" brings up the numeric keypad switched to numbers and symbols, so both work, just depends on your application. For me I only need numbers so I used type="tel" for ease of use and it worked great!
