Cheapest way of using a brick phone?

[LifeofBrienne]

Hi, I’m getting my son a Nokia and wondered if there’s a sim deal out there that just lets you pay for what you use and top up as needed, rather than having to pay a fixed amount every month. Does that still exist? Feels so old school!

It isn't quite what you asked but asda do £4 monthly text and talk bundles.

Thanks! We’ll probably go for Asda mobile.

We use giff gaff - its fab and lots of different tariffs to choose from

We use Smarty it's been great so far with no issues at all, probably been with them for the last 2 years or so.
