Do not bother with KnowRoaming. We just tried it on a cruise - tried it in 6 different countries in South/Central America - and it worked only once. We spent a huge amount of time being frustrated with it. Saw a lot of spinning circles... Luckily, I had another phone with Google Fi service - otherwise we could not have even contacted their technical support to try to fix it. They had us try something new and different every day and then told us, sorry, no refunds since you opened the package. We used the physical SIM, not the sticker, but it was totally useless and a waste of money - way more hassle than help. Google Fi was flawless - if you have an unlocked phone, they are able to work with more devices now on Beta.
