How to check the mobile phone number can also recharge the use? My mobile phone number has expired, but I don't know if it has expired for more than 90 days, is there any way to check?

Depending on the definition of overdue (how long overdue), short-term overdue is fine. If the operator recovers the (empty number), or re-issue the number, no no, maybe re-issue the number, to help others charge the phone bill.
