So, what problems have you encountered?

The mobile phone number is an 11-digit number, which is \ d {11}
To be more rigorous, determine the phone number prefix.

However, you have a good regular expression. you can see that 15X 13X 18X does not have any good suggestions.

Is there any more complete verification? just let us know.
