Thanks. I did purchase it and I think Need is correct in that the charge actually appears on the next bill. I purchased via the app and it did give me a screen that said "International Pass $50 One-time charge to your bill" and after I hit the agree and pay button, it gave me a "Thank You, Pass now active" confirmation, so I combined those two screenshots together for a make shift receipt and I'll just mark it as a 'cash' transaction since work doesn't cover my regular cell service.

My statement finally issued. It was $50 + taxes/fees, so that was another ~9%.
