No, it’s not higher if you buy it on the first day. You just tell them the App would not work.
Looking at your 1st post….did you click on the button for 1 device? Then, you clicked on Buy Plan?
Did you check on the App, your payment to make sure the credit card was in there and correct?
BTW, did you send an email to IT
for help?

But, you CAN buy it on the first day at $15 a day and 50% discount if you’re Elite/Platinum. Don’t remember if you’re traveling soon, but do try the email address.
