The IKO mobile app is expected to be unavailable from 00:01 to 03:15 (PKO BP wyłączy aplikację – GSMonLine) (PKO BP wyłączy IKO. Zapisz datę 15 listopada – ITHardware). Customers may also run into problems with the transactional online service of PKO Bank Polski, PKO Biznes, and the bank's website.

According to the bank, the mobile app for business customers, PKO Biznes, may also be affected during the work.

What will keep working

The bank says a number of payment functions will remain available. Cards can still be used in physical stores and online, and cash can be withdrawn from ATMs. Card payments online can still be confirmed with an SMS code and the card PIN under 3D-Secure, and transactions can be authorized with SMS codes instead of mobile authorization.

The bank recommends completing important transactions before the work begins.

Comparison with similar work

This is not the first such break this year. Mobile banking at PKO BP was also disrupted on September 6.

What to do

Customers who need to make transfers or other mobile-dependent operations should do them before midnight on Saturday. Those who rely on SMS codes should make sure their phone number is current, since that method will be the fallback during the break.
