Before We Start: The Quick Checklist
You don’t need to be a tech wizard to do this, but you do need three things:

- An Active BSNL 4G SIM: You need an active plan.
- A Wi-Fi Connection: This is crucial. You must be connected to a Wi-Fi network (it doesn’t have to be BSNL Fiber; any stable Wi-Fi works).
