Credit card EMI vs personal loan — which is cheaper?

On credit limit increase: most banks auto-review every 6 months. If you use 30-70% of the limit and pay in full, you'll get an automatic increase. Don't call and ask for it explicitly — banks take it as a sign of credit hunger and sometimes lower the limit instead.

For the fee waiver condition: most banks count only retail purchases, not EMI, wallet loads, or fuel (in some cases). Read the TnC PDF linked at the bottom of the fee-waiver email — it's usually 2-3 paragraphs of fine print that change everything.
