Although some take a new SIM card without giving special importance to the matter. You forget the old number with a new SIM, but here lies the danger. Because, telecom companies reactivate the closed number within 45 to 90 days. In that case, the ownership of your old number goes to someone else. As a result that person can get all your OTP. Due to which you may face serious problems, the account may be empty. Let’s find out what to do in this case.
