As @FreshMan said all COD cheats available only in premium package as a free bonus and keep in mind some cheats are excluded from premium package and one day trial, you can check each cheat from here:

Also you can check our cheats status from here:

And to answer your question if we have a feature to unlock all, then the answer is no. Unfortunately we dont have this feature.
