如何从电话号码中删除“+”和国家/地区代码？

Question

I am using following API to get a phone number; however, some of the device will return the number in following format:

"+" + countrycode + phone number Ex. +12062436969

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
String phoneNumber = tm.getLine1Number();

I would like to find out a way/algorithm to remove this "+" sign and the country code, so I will get only the last ten digits. Ex. +12062436969 -> 2062436969

I believe I only need the last ten digits. could anyone please suggest any idea?
