I opened my account with SBI 42 years back , I have had times when I have stood in queues in their old fashioned branches but have got my work done without extra charges or hidden charges and my money has been safe that is what has let me be an account holder of this erstwhile trusted & safe bank. The other factor that has kept me glued to SBI is you will find a branch of SBI in any place you go to the smallest town or village to the most sought after international venue.
Also, like to mention their prompt manner of handling student loans.
