Sky Mobile has announced that this weekend (June 15 and 16) it will transmit free unlimited data to all its customers. This is a celebration for the network, having welcomed over a million customers since 2017. The weekend-only offer will apply to all customers with just a SIM card and a phone subscription for the entire Saturday to Sunday . It means streaming movies, watching TV and listening to music, playing games or just using a web browser, all of these are totally free and unlimited. If this sounds appealing and you're considering a new system, good features are waiting for you. Roll – means your unused data will be rolled into the Sky Piggybank next month for further use for a period of up to three years. Mixer, allows you to vary your monthly data allowance depending on what you use. Look, you can stream unlimited Sky Go, Sky Sports and Sky Kids without encrypting your data (not just for this weekend). Or if you want to try something different, all your options are clearly explained here in our best SIM-only deals and here in our best mobile phone deals. Sophia Ahmad, Director of Sky Mobile, said: "Attracting over a million customers in less than two and a half years is a testament to the power and appeal of our fair and flexible mobile network in the market, such as handover of data with Roll, has helped us. We are delighted to be able to celebrate with our customers by offering a free data weekend." For more information, visit the Sky Mobile website.
