USA - AT&T Prepaid. $40 per month. Unlimited talk and text in/to the US, Mexico and Canada. “Unlimited” data BUT after 15GB 5G data, speed is reduced to 3G(?) speeds so email, messaging and other apps using light data still work OK but browsing is verrrrry slow - forget about streaming at that point (it also includes roll-over of unused data from previous month). I don’t usually go over the 15GB though due to wi-fi available most places I am usually at.
Ya, US dollar is 0.79 GBP. So my $40 plan would “only” be £31. Still much more expensive for sure though.
