I'm a switcher 😂
Despite being with o2 for over twenty years, their latest atrocious price hike had me hunting for a better place to be a loyal customer. Ecotalk won hands down. They are actually not quite the cheapest, but the deals are good, cheaper than o2, and their ethos with regards to nature seems sound. It's only been a couple of weeks so far, but the switch was smooth, my number came over within a day and I actually have better signal in the wilds around me than I did with o2. Win win for me and I highly recommend switching.
Just one niggle, c'mon Ecotalk provide e-sims too please! Even less plastic waste then! :)
