There is a huge amount of SIM only deals available right now but realistically, two options are standing tall above the rest thanks to their combination of data and low costs.
These two plans come from Smarty and Three. For those with a bit more money, Three’s unlimited SIM is going to be the way to go. Not only is it offering unlimited data, calls and texts but it also supplies you with 5G access at no extra cost.
What’s really great about that Smarty SIM is that it runs on a 1-month rolling contract, meaning you can leave at any time.
