I agree it's probably the cheapest and seamless service if you can tolerate the terrible call quality when you're domestic (especially indoors). Can you hear me now?
Works great indoors everywhere I go..and get wx, flt plans etc all over the world. Use WhatsApp in Germany, SA, UK while in the street to call home with no problems, at time the 2g is slow but always works. About 50% of crews have it, the others almost all have ATT and pay 10$ a day extra, adds up on a 5 or 6 day international trip.
