Tata Docomo — Old Sim Card activation

Hello Sir/Madam,

I was using Tata Docomo sim since 2016 and in January 2018 I lost my sim card at home which was very important but I hadn't done anything to recover my number, but today while cleaning my house I found my old TATA DOCOMO sim in a file and I want to reactivate it as soon as possible because i want OTP to open some applications, please help to reactivate my sim card, it's very important.
