I have been using jio sim Since 2018 and it’s been fantastic in term of network quality and affordability. Recently, I decided to try Airtel, but I found there recharge plan to be quite expensive compared to jio so I decided to port my Airtel SIM back to jio. The process was super smooth-within 3 hours of a jio customer service represented came to my home and complete the porting process. Jio’s recharge plan are definitely more budget friendly and their network coverage are also good.
Also with the jio recharge we can get the free caller tune for a month but for the Airtel or the another same we have to pay for this.
