You are TOO skeptical. It works, here in Europe, and has been tested. Here, howerer, is pretty much GSM/Nokia monopol. But Siemens, SonyEriccson,etc shows Noika compatible graphics messages too. So it's preetty reliable. Anyway when you subscribe for ticket, You register in their database with your phone number automatically. And even if sms gets lost, which is highly unliekely, (I havent lost any sms for years) you still can ask them to doublecheck their database.
