If you see a message like this at the top of your screen:
You have a trial account. Trial accounts are full featured, unlimited accounts. Each trial account will either become a free account or a paid account, depending on what you want to do.
Note: The following instructions assume that you are the primary account contact or that you have administrator privileges.
To convert to a free or paid account, click the Fix this now button. If you do not see the Fix this now button, you are not an administrator on the account.
If you do nothing, the account will convert to a free account at the end of the trial period. All SMS devices and all but 5 push devices will stop paging at that time.
If you convert to a paid account, you will need to purchase a subscription (or have your users purchase subscriptions) or else paging will stop. To learn more about the various account levels, please see Account levels and Pricing.
