## How Matrix eSIMs work (facts commonly asked)
- Buy a plan on matrix.in, then a QR code is e-mailed within seconds. Scan it, let it install, and the plan activates automatically when the phone connects to a network at the destination.
- The phone must be eSIM-compatible and carrier-unlocked. Check by dialling *#06# - if an EID number appears, the phone supports eSIM.
- eSIM plans can be recharged/topped up during the trip without visiting a store.
- KYC is required for eSIMs as per Indian DOT guidelines.
- Plans are either data-only or include calling minutes; the plan name states which (for example "Data Only" or "200 Mins").
- Hotspot/tethering: available on most limited-data plans; some unlimited plans restrict it because of fair-usage rules.
