What exactly does DotDot do?
At the end of the day or month, many gigabytes remain in our mobile subscriptions. DotDot allows users to trade these gigabytes completely anonymously.
How is it done?
A DotDot device, priced at approximately ₹1000 in India, is paired with a phone to create a 100-metre Wi-Fi zone. Users within this range can purchase data from the DotDot network.
Before we get into the details, what inspired the name DotDot?
My idea was to connect the dots between people by helping them share gigabytes of internet data, all while ensuring the anonymity of both the seller and the buyer.
Why would someone want to use such a device when they can use their phone as a Wi-Fi router?
DotDot, unlike a phone, does not require sharing passwords, ensuring optimal cybersecurity for users. Additionally, while a phone’s Wi-Fi zone is limited to 25 metres, DotDot extends this range to 100 metres.
Can you explain the whole process from a user’s and a buyer’s point of view?
