How does Holix USSD Vault work when I have no data?

Once you save Holix USSD Vault to your phone's home screen while online, it caches locally. When your data finishes, the app opens offline and generates secure telecom USSD strings that dial directly through your mobile network's voice channel.

What if my phone number is not registered with my bank?

Bank USSD transactions require your calling SIM card to be linked to your bank account. Holix USSD Vault includes built-in Multi-SIM warnings and alternative data-gifting shortcuts if you are using an unlinked number.
