You almost have to have a laptop, for home contact and the company manuals. Most of the hotels provide wireless internet so you can keep in touch with e-mail. I'm only on my second long trip, and I haven't called from overseas yet. I do have Vonage VOIP at homewhich has low international rates, 3 cents a minute to Europe, for example. My plan is to e-mail my hotel number home and tell my wife when to call (so I can sleep). I have a Sam's Club card to make priority calls from anywhere if needed.
