PCS allows several stages of profile verification. According to this you will be able to unlock some features of your PCS card.

If your profile is verified at 25% or 75%, you will be subject to restricted limits on withdrawals, payments and top-ups.

In order to benefit from the higher ceilings, all you have to do is to fill in your profile at 100%.

To do so, go to your mobile app or to mypcs.com and complete the verification of your profile (upgrade to premium).
