FYI: I returned from 26 days in Italy on April 26th. My cellular service is through Consumer Cellular and after reading on the forum in March about how it went for Sue using their international service I decided to try it for this trip.
I’ve used eSIM from Airola in the past with varied success but my last trip to London it just quit after working fine for almost 2 weeks and I ended up buying a SIM card at a shop in London to finish my last week.
So I called CC and set up an international account very easily and it all worked as promised. I am VERY dependent on cell service to get around and I use a lot of Wikipedia when touring the many, many churches I was in and out of during my travels. I texted my husband and others quite a bit too. Also used WhatsApp although I never did make any actual phone calls. I ended up using about 8 GB. Anyway it came to about $17 dollars from what we can tell from our online account. I consider that a big success for little money and will be going with them for my future trips.
