I just got my secure SIM and set up a Serve account. I go into the app and see that my Serve balance is $0.00 (obviously, I just set up the account). I tap the + sign to add money to the account and it takes me to the Serve site. However, it does not let me do anything after that. I cannot tap the number field to state how much I want to add to the card and nothing happens when I tap the add new source button. Has anyone else experienced this? Is their website not compatible with IE on Windows Phone? Is there any way to add $ on the phone?
