I just signed up for the Data Global Add-Ons for Smartphones, PDAs and iPhone from AT&T for my iPhone. Yes, I was very excited to learn that this was expanded to Israel recently. Today, I ordered the most expensive option, because I need to assume I will use what I use here in the states, on a high day for my trip to Israel.

Normally, I am on WiFi networks here. But on Sunday's I notice my usage on the data network spikes. So I picked the highest usage, which is about 6MB and went based on that. I signed up today, which gives me 80MB of usage until I get back to the states. Here is a picture of my data usage bar in my account for this international plan:

I will use the data plan probably 10 days, maybe less. Also, 4 of those days, I will be around wifi networks, most of the day. So I should have plenty of data to not go over the plan. If I do, I get hit with a fee of $.005/KB - which can get bad, quickly with the iPhone.

Now my only concern is battery life...
