Hi all...used Orange Travel Holiday Zen eSIM last year in Scotland with zero problems for both GPS Google Maps and for local calls (which proved handy on multiple occasions to call ahead to restaurants and our lodging when originally thought data only would be best). This year we have switched to T-Mobile Magenta Max which I know provides international service but at very slow speed. I know we had excellent service with Orange even in remote parts of Skye and the Highlands but curious if there are any other providers who might work or have better deals?
WhatsApp works fine for a quick call or text back to the States so I'm really only looking for enough minutes and data for 2 1/2 weeks in Scotland.
