I recently purchased a data plan through AT&T for a trip to Europe. The plan gives me 1G of data and $0.35/min for phone usage. My question is this: While sending a text from Europe to a number here in the US is that number note on your call log on your monthly bill. When I was in Mexico a couple years ago I was using SMS texting and all numbers in which I used were listed on my call log. Will this happen when using Whatsapp?
