It's not a large market. I've used them myself on iPad when I travel (as they don't do voice or SMS, just data). Sometimes they work, sometimes they don't. Pain to move them to other devices or to recharge sometimes. Many are dirt slow as they're basically foreign carrier roaming SIMs rather than native local SIMs.

It works but I certainly wouldn't want it to be my only choice when abroad.
