Greetings from Aqaba, where if I position my phone just right in my hotel room window, I get a ~1.5mbps connection I can tether to versus the 0.2mbps connection the hotel has.
Thanks for the warning. My phone has so far not connected to any Jordanian providers (it goes to "No Service" when I move it away from the window or walk through the streets of Aqaba), but I turned off roaming just to be safe. I was hopeful that the same principle behind the amazingly great price (and even 99 NIS is a steal for the service they're providing compared to the U.S. carriers) applied to their overseas roaming agreements, but I suppose they're just passing along the ridiculous charges that the foreign carriers charge them.
I was surprised at how good and extensive coverage was through pretty much the entirety of the Negev, even isolated sections between towns.
