How to change your credit card number
First and foremost, if you are changing your credit card information, you need to add every piece of information about the credit card like it was your first time. Even if it’s already auto filled, do it anyway.
When you log in to your Public Mobile account, go to the Payments button.
On the right hand side, click on Manage Subscription.
Then click on Manage Payment Method and remember, change and edit everything even if it’s already auto filled.

Sometimes the system can be finicky. If you come across errors 3 times, you'll be locked out for an hour to protect your account. After an hour or so, go into your browser settings and clear your cache. Then restart your browser and go into Incognito mode and try again. If you're still having issues, click on that little chatbot icon at the bottom and enter Customer Service Agent and go from there.
