Does iFixit not sell that battery? If they do then I would recommend buying from them even if it is a little more expensive than Amazon so you help support right to repair legislation, not to mention supporting their repair guides, tear downs, etc. that benefit all of us.

Ya, US dollar is 0.79 GBP. So my $40 plan would “only” be £31. Still much more expensive for sure though.

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.
