The receipt skips this part
The SMS says 5G unlimited. The status bar still drops to 4G on the way home, in the lift, at night. Pink is the 5G you can point at. Blue is the 4G that used the rest of the day. Orange is a 3G dip. Purple is a rare 2G hour.
Change what you paid and the split moves with it. That rupee line is the recharge cut by hours, so you can see where it went. The shop receipt still prints one 5G plan.
Home Wi-Fi stays off the sum. A 5G plan is the mobile network. Open Settings, tap Count my hours, and match the chip to the status bar. The clock runs while this tab stays open.
