(Stupid question) I’ve moved into a new house and don’t have WiFi for a bit, can I just get a no contract £12.50 (for two months, then up to £25) sim for two months, then just cancel it before the price goes up?

Pretty much says it in the title, I found an offer on Uswitch for Honest Mobile, 2 months £12.50 then £25 a month. I only need to use it as WiFi for a month, so can I just cancel it before the price hikes?

It says no contract on uswitch and I’m just trying to be safe!
