Note: I'm not on DTV so my KTB account are good and clear.
Avoid KTB.
Latest app update locks me out from my own account saying my phone was modified. The customer service woman also blames my phone and don't want to listen. Guess what? Samsung customer service clears my phone from any errors and other banking apps from multiple countries are still working. Awful app develompent and customer service. Bring your business somewhere else instead of this bank even though you have visas that allows opening accounts.
