how to set min 10 number for mobile number validation?

Question

I am using this regular expression for mobile number,

[Required(ErrorMessage = "Required")]
       [DataType(DataType.PhoneNumber)]
       [RegularExpression(@"^[\+\d]+(?:[\d-.\s()]*)$", ErrorMessage = "Not a valid Mobile number")]
       public string MobileNumbers { get; set; }

 But not happening validation when enter less than 10 min number.

And for email validation, 

[Required(ErrorMessage = "Required")]
       [EmailAddress(ErrorMessage = "Invalid Email Address")]
       public string EmailIDs { get; set; }

But this is not working when enter look like this,

 

 How can I solve this issues? please help me...
