Yes if you read my title that’s exactly what Jio is at times you may get download speeds on jio upto 20mbps and at times just 3 mbps you heard it correct just 3 mbps during peak hours.Video streaming downloading will work great at times and some times you won’t be able to even send a WhatsApp image due to low speed, The reason for this is jio keeps adding new and new customers but there cell towers are not capable to handle so much traffic which means in minimum investment they want as many customers even if the quality is not constant my review for jio would be use it a secondary sim in some tablet to surf net and watch videos don’t make it your primary phone number
