I don't think there is a "default" credit limit for MySuperPlan 999 but it would have to be more than Php 999.00.
Just to clarify the definition of CREDIT LIMIT according to Globe's Terms and Conditions which ironically is different from the layman's understanding of credit limit... it is different from a SPENDING LIMIT and both are defined... to quote:
ARTICLE 3 CREDIT LIMIT
3.1. You will be assigned a credit limit which specifies the maximum recurring charges which you may subscribe to.
3.2. We reserve the sole right to review the criteria for the increase/decrease of your credit limit and approve or disapprove any such request subject to existing terms and conditions. We may also proactively increase your credit limit and notify you thereof. If you do not concur to your new credit limit, you have to inform us thereof within the specified period as indicated on the notification. Failure on your part to do the same shall be deemed as acceptance of the new credit limit.
ARTICLE 4 SPENDING LIMIT
4.1. You may opt to set a spending limit which represents your cap which will enable you to manage your usage within a billing cycle. If you exceed your spending limit, we may require payment even before the end of your billing cycle or we may notify you through any of your contact details/numbers. Notwithstanding non-receipt of any notification, you may request, at any time, details about your unbilled charges by calling our Customer Service Hotline (+6327301000); visiting any of our Globe Stores nearest you; or consulting your account manager. Failure on your part to inquire about your unbilled charges for whatever reason does not absolve you from liability in settling your outstanding balance in excess of your spending limit. Further, we may bar, suspend or temporarily disconnect the Service as soon as you exceed your spending limit, or when otherwise warranted by abnormal usage patterns or other circumstances, without need of prior notice and liability on our part. You agree to pay for all usage whether within or in excess of your spending limit in order to continuously avail of the Service.
4.2. We reserve the sole right to review the criteria for the increase/decrease of your spending limit and approve or disapprove any such request subject to existing terms and conditions. We may also proactively increase your spending limit and notify you of the increase. If you do not concur to your new spending limit, you have to inform us within the specified period indicated in the notification. Failure on your part to advise us within the specified period shall be deemed as acceptance of the new spending limit.
