FreedomPop in Spain was a free service until recently. It was completely unusable. They were selling Three (UK) cards that worked here in roaming. The internet service simply didn't work. They were assigning telephone numbers they borrowed from another company. That company didn't have a licence to lend their assigned numbers, that was illegal, so they had to stop providing their services and I suppose they'll get fined, big time.

Now they stopped giving that free service, and you have to pay. I don't think many people will pay anything. It's a scam.
