I don't think you can really compare the prices of this kind of low-data, many-sim offer with consumer stuff. Recently I talked to a national (Portugal) operator who offers M2M SIM cards and their price for national only cards is 0,19€/MB, international one similar to this 0,27€/MB. Twilio's price is pretty good compared to what they've got.
