Which banks allow us to easily & properly turn off SMS alert charges, or SMS alerts r free in that bank ?

[harshn]

AU charges upto Rs. 15 per quarter (depending upon the no. of alerts) for their Digital Savings Account (0 balance account), but the SMS alerts can be turned off from the mobile app.

Pls share screenshot of that option or tell me where to navigate inside app , Is that option still working, after turning off were u charged for SMS alerts ??
