I know that there has been plenty discussion about SIM cards... but the discussions seem to be a few years old. I'm not sure if anything has changed, but I would like an updated opinion on what type of SIM card to purchase, cost and from whom. We want to be able to use the phone to make hotel reservations along the way, and use data to find our way to where ever we're going. We'll use wireless to send messages home. We are starting in Amsterdam in September, taking an 8 day river cruise down the Rhine and landing in Basel. It's Basel where we want to start using the phone/data. I bought a new phone, and am getting my old Samsung S4 unlocked so that we can use it exclusively for travel in Eu.
Thanks for any advice.
