I'm not sure if I should post this on mobile or travel.
I am traveling to Europe and the UK next year and am looking for the best-value Sim Card for 24 days. I need probably about 20–30 GB. I managed to get one last year on eBay for $35 that did 30 GB in the UK and Europe, but I can't find it anymore.
Looking for recent priced deals. Also I don't want to move over to Boost/Vodafone for their $5 a day deals.
Can you use an eSim? That will be the easiest.
