To be honest, OnePlus 3T is the cheapest smartphone to offer 128GB storage at this pricing. We too had quite a few queries asking when the 128GB is coming back. And today, OnePlus dropped a mail informing about it. For ₹34,999 OnePlus 3T is still your best bet thanks to 6 GB RAM and a Qualcomm Snapdragon 821 processor.
To begin with OnePlus 3T 128GB will be made available for purchase as an Amazon Prime-only member sale on February 17, 2017 from 10 AM – 10 PM. This will be followed by open sales from February 25th 21st, 2017 onwards. Go get yours, its Amazing.
UPDATE 20 February 2017 : OnePlus preponed the open sales which will now be starting from February 21, 2017 midnight. The wait is now over.
