Like the European-based SIMs, the costs for North America (incl Canada and Mexico) are VERY high. So presumably this is a US DID, forwarded to a global SIM service from another country?

For US people travelling to Europe it looks like a OK deal (if they don't mind an annual fee, and revealing their SSN), especially since they can forward their US cellphone to the domestic number. But for travelling from the US to neighbouring countries (the majority of US international travellers) it works out worse than roaming (even prepaid roaming!) in most cases.

Not being able to send/receive a text would be a deal-killer for some, and is often the hardest thing to get working on a forwarded number, so it'll be interesting to see when that (and data) will be available.
