My Happy New Year Offer got expired today at 4:41 a.m and not it's converted to Jio Summer Surprise Offer, which will be expired on 20th July. Moreover, the speed has also been increased from 1 mbps to now 4 mbps at my home (Tested in TRAI & Speed Test App).
most probably you will be disconnected in 1-2 days as many have got their summer surprise active.. I don't know why they are doing in batches. Some have validity 18th July, some 19th, 20th, etc.
