Charges AFTER buying roaminng add-on
I bought an international roaming add-on for Switzerland using the WiFi at the airport. I got a text confirming the purchase. A few minutes AFTER this I got a text saying that I had used some chargeable roaming services. Shortly later came another to say that I had used 80% of my Bill cap. I didn’t make calls or sends texts so I can’t understand why these charges appear.
