To fully understand what's happening, first, here's a little context.
Jio urged Ookla to revoke the reward given to Airtel on October 6 that it is the fastest network in India.
Reliance Jio didn't respond to Mashable's request for comment.
In the meanwhile, Airtel and Ookla have stood by their previous claims.
Jio also said that Airtel, as a dominant player in the Indian telecom market for the last 22 years, can not plead ignorance of the implication of undue advantage it would gain by the use of such a word.
In a recent letter to advertising watchdog Advertising Standards Council of India, Reliance Jio has said Airtel's claim and the related advertisement that its the fastest telecom network in India is misleading and incorrect.
Jio also alleged that Ookla, the owner of Speedtest app, charges money for giving such awards and the company has also approached Jio for the same for the very quarter it issued certificate of fastest mobile network to Bharti Airtel.
A statement from Airtel followed. "We believe that this is a deliberate attempt to malign our brand and misguide customers through a campaign of misinformation, which is something we now come across on a regular basis, in particular, on social media platforms".

However, Ookla would "charge substantial sums of money for this objective and especially for publicly using the award and test results". For instance, let's assume you have a Vodafone, Airtel or Idea SIM card in the SIM 1 slot for calls and text messages, and a Reliance Jio SIM in the second slot for mobile data.
Dual-sim capable smartphones are extremely popular in India.
However, there is a big debate here, and the accuracy of Ookla's speed test results have been questioned.
We, personally ran the tests a couple of times in various scenarios as well as smartphones and found the allegations to be completely true. "The carrier displayed by the Speedtest mobile application is based on the "Active Carrier" value returned by the Android API". Which Jio could subsequently use, leveraging Ookla's brand. We confirmed the bug after using Speedtest app in a number of scenarios. "The results include all mobile tests, regardless of connection technology", said an Airtel spokesperson. It remains to be seen how soon Ookla fixes the bugs.
