Only Airtel works well in some cities, with Vi, you can only send money by phone number, so no scan and pay. If many Vi users port to Airtel and tell them broken *99# as reason, they might fix it. One way to support #FreeSoftware. Because UPI apps are one common reason people stick with #android or #ios. Working UPI would bring #mobian / #postmarketOS closer to mainstream. If you dont have a specific reason to stick with Vi, I recommend you do it. #UPI #MastIndia #Vi #Airtel #bhim
