Three’s market-leading unlimited data SIM only deal is still available for £16/pm SIM only deals

Got a new phone over the Christmas period? Or, has your phone contract just ran out and now you need a new SIM? Either way, one SIM only deal is standing out above the rest right now.

Three’s unlimited data plan dropped down to just £16 a month over the Black Friday period and now, a good few months later – it’s still live. That not only makes it the cheapest unlimited data SIM but also the best value SIM on the market by a long way.
