Hi @Ankur Bawiskar 

I checked the above script and it's accepting more then 10 digits and no error message is displayed.

try this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue == '') {
        return;
    }

    // Remove all spaces from the input for validation
    var value = newValue.replace(/\s/g, '');

    // RegEx Explanation:
    // ^\+?         : Optional '+' at the start
    // \d{10,}      : At least 10 digits
    // $            : End of string
    var regex = /^\+?\d{10,}$/;

    // Count of '+' signs
    var plusCount = (value.match(/\+/g) || []).length;

    // Validation checks:
    // 1. Only one '+' at the start (if any)
    // 2. At least 10 digits
    // 3. Only digits allowed after optional '+'
    if (
        !regex.test(value) ||                // Fails the main format
        (plusCount > 1) ||                   // More than one '+'
        (plusCount === 1 && value.charAt(0) !== '+') // '+' not at start
    ) {
        g_form.showFieldMsg(
            'mobile_number', 
            'Please enter a valid mobile number: minimum 10 digits, only one "+" allowed at the start, digits only.', 
            'error'
        );
        g_form.clearValue('mobile_number');
    } else {
        g_form.hideFieldMsg('mobile_number');
    }
}

@Ria 

In your question you said minimum 10 numbers so it will accept more than 10 as well

What's your actual business requirement?
