Hidding a Rateplan means you don't want it to appear in general search or under special offers.
Only customers with a PROMO / RATECODE will have access to this rateplan.
A rateplan can be hidden under Step 3 of rateplan set up.
Tick to "Hide from General Availability Search" and enter a Ratecode if required.
Note: Ensure that you do NOT enable the Rateplan to appear on any of the specials pages.
