Users across mobile networks in India experienced a prolonged outage on Monday, August 18 — starting majorly with Airtel, then to a lesser degree with Jio and Vodafone-Idea.
What Airtel said on network being down

The issue was first flagged in Delhi-NCR before 5 pm, and later in Mumbai and Bengaluru too, spreading across India soon after.
“Our customers from Delhi-NCR are experiencing some voice calling issues for the past hour or so," a statement by the company read, “Significant part of the issue has already been resolved and our engineers are at work to resolve this fully. We deeply regret any inconvenience.”
Extent of Airtel outage
- Downdetector, a portal that monitors tech glitches, saw over 3,600 reports of Airtel outages at around 4:30 pm on Monday, as against a baseline of less than 15.

{{/usCountry}}Jio shared a press statement that said its own network did not have issues.
“We would like to clarify that the Jio network has been operating normally throughout the day with no operational issues. All Jio-to-Jio calls and calls from Jio to other non-impacted networks have been working seamlessly. The only problem observed was in calls made by Jio numbers to a specific impacted network customers, due to downtime on that network’s end. This did not affect Jio customers calling within the Jio network or connecting to any other networks. We assure our customers that the Jio network continues to perform optimally, and services remain fully available,” the official said.

“@Airtel_Presence @airtelindia services are completely down. Unable to make or receive calls and even messages are not working. This is causing serious inconvenience.

Another user wrote, “If you are an #Airtel user, and unable to make calls, you're not alone. Seems like a widespread outage.
Connectivity of @airtelindia facing serious issues. Don’t panic if you are not able to get in touch with your loved ones. Just be patient. #Airtel #Mobile," one user wrote on X as #AirtelDown trended on the platform.
Another user added that it is not just a localised issue in Delhi-NCR, adding that Airtel network is down across the entire country.
“Ported from Jio to Airtel due to internet issues, but facing even bigger problems now. Not able to use data while on calls & no proper response from customer care. Really disappointing!” an X user complained.
