I carry an inordinate number of gadgets and cables when I travel. Camera(s), phone, tablet & laptop (yes, both), cables and chargers…it all adds up.
This blog post has a handy list that I plan to use for my next international trip (to Iceland).
My tablet is an iPad Mini set up for T-Mobile, and it has a Simple Choice account which provides unlimited (but slow) internet data in almost every nation in the world. The T-Mobile account costs only $20 per month.
For voice I use a Republic Wireless phone.
