in like 2005, one could get an unlimited data add-on to an AT&T dumb phone for something like $15/mo. If you managed to get a 3G dumb phone, you'd get a 3G-enabled SIM card. Just take the SIM and pop it in whatever GSM device supporting the right frequencies and boom cheap unlimited data. It seemed like as long as you didn't use a device AT&T sold they never noticed it wasn't your cheap dumb phone. It was tricky buying Euro phones. They'd mostly work but usually didn't support the more widespread lower frequencies for AT&T (was it 850 or 900MHz? I don't quite remember). Usually the higher frequencies were well supported like 1900MHz and 2100MHz, but those were pretty hit and miss on coverage and would often die once you went inside a big building.
