Its my real experience: -
It was the time when jio was launched to compete airtel , voda , idea etc. at that time I bought the sim on saying of my son . In starting it was good but slowly slowly its speed graduay start decreasing and I dont know what happened to it daily after 5-6 pm in evening to the whole night . The internet just downgrade to very very slow speed just lile below 2g. I called customer care and they said to me that our customers are increasing day by day therefore we are adding towers they asked me my address area etc. and sent me message a new tower will be added to your area in 90 days and approx after 90 to 100 days I called them again and said the same thing as the speed was slowly and it just stops in evenings , they reacted like they dont know anything and asked my area details again and said to me a new tower will be added to your area in 90 days . I became angry I waited for 90 days and you are saying again 90 days . Whats is this , then I remeber I threw the sim of Jio and now I am using Airtel and it is good and better then jio
