How remote lock works on a DPC-enrolled financed phone

Three levels of enforcement — each appropriate for a different overdue stage.

Stage 1 — App Restriction

Used for: 1–3 days overdue. Block access to entertainment, social, and gaming apps while keeping calls, SMS, and camera working. Customer gets a reminder notification each time they try to open a blocked app. Least disruptive — designed to prompt action without confrontation.

Stage 2 — Soft Lock

Used for: 4–7 days overdue. Locks most of the device but keeps outgoing calls to the retailer's number working. Lock screen shows retailer name, payment amount due, and a "Pay Now" link. Customer can resolve directly from the lock screen. Gets the message across without feeling like hostile seizure.

Stage 3 — Hard Lock / Kiosk

Used for: 8+ days overdue or high AI risk score. Full device lockdown to kiosk mode — only the EMI collection screen is accessible. Customer cannot make any calls, access any apps, or use internet. Only the retailer's unlock command releases the device. AI auto-lock decision can trigger this automatically.

Why the remote lock cannot be bypassed

Device Owner mode registration

When enrolled via EMI Locker's DPC flow, the app is registered as Device Owner at the Android OS level during setup. This cannot be undone by the user without the Device Owner (retailer) removing it from the panel. Clearing app data, disabling permissions, uninstalling via Play Store — none of these work on a Device Owner profile.

Queued enforcement when offline

If the device is offline when a lock is issued, the command is queued. As soon as the device connects to any network — WiFi, mobile data, even a different SIM's data — the lock is enforced. Customers cannot avoid enforcement by simply turning off data.

Automatic Factory Reset Protection

Every enrolled device automatically gets Factory Reset Protection (FRP) enabled — no extra steps required. If a customer attempts a factory reset, the phone locks itself and cannot be set up again without your authorization from the retailer panel. There is no bypass path available to the customer. This turns an attempted wipe into a dead-end for them — and a recovery opportunity for you.

SIM swap alert & self-lock

When the SIM is removed or changed, the retailer receives an immediate push notification and panel alert. The device can be configured to self-lock automatically on SIM swap — common for high-risk accounts — or to alert-only for standard accounts. The retailer approves or blocks the SIM change from the panel.

Remote lock for financed phones — FAQ

Log into the EMI Locker retailer panel, find the device by customer name, phone number, or IMEI, and click "Lock Device". The lock command is pushed to the device via Firebase. The device enforces the lock within 30–60 seconds if online, or as soon as it reconnects if offline.

The customer sees a custom lock screen showing your shop name, the overdue payment amount, a payment link or UPI QR, and your contact number. They can call your number from this screen. They cannot access any other part of the phone until you issue an unlock from the panel.

Yes. The lock works via any internet connection — it is not tied to the original SIM. Additionally, EMI Locker detects SIM swaps and can automatically lock the device or alert you immediately when the SIM is changed.

No. Only the retailer can unlock the device from the panel. If the customer attempts a factory reset, Factory Reset Protection automatically kicks in — the device cannot be set up without the retailer's authorization. There is no bypass path available to the customer.

Remote lock makes the device unusable while keeping all customer data intact — it's reversible. Remote wipe permanently erases all data on the device — it's a last resort for fraud scenarios or device abandonment. Both commands are available in the retailer panel with full audit logging.
