After actor Amitabh Bachchan on Tuesday took to Twitter to complain about Vodafone's network, rival Reliance Jio stepped in and offered him a SIM. “Sir, we would be happy to deliver a Jio SIM to you & activate it instantly through our Aadhaar based eKYC home delivery process”, tweeted Jio. Later Bachchan thanked Vodafone after the glitch was fixed.
