Leona, this is what I tried to do at the airport last December, but even though it took the money from my balance, the data didn't work. Hopefully that was an anomoly. The other thing I had a problem with was adding money to my Top Up card. When I went to the Mailbox they said their machine wasn't working. I then went to Market Garden, used their machine, but it added money to my phone, not my Top Up card. We need money on the card to keep the phone number active between visits. Any insights into that?
