The distance is not a factor. But GPRS is. Your aren't getting 300-400 kbps over GPRS. That's more like a 3G or UMTS speed. GPRS gives you something like 56kbps type speeds.

Now, I would be VERY careful and look at the fine print of my terms. Data almost always incurs roaming charges when overseas. And it's fairly expensive too. People have run up phone bills in the thousands when going overseas and not realizing how expensive data roaming is. You may not pay roaming for voice, but I'd be willing to bet you do for data.

Back to speed, it would all depend on the network in Israel.

I would double and triple check that data plan details. I've never heard of an all you can consume international data plan. It's not treated like voice at all. Whether you use the phone for Slinging or not, I would seriously check to be sure as it's very expensive typically.

And yeah, GPRS speeds won't work for Singing...
