Or message us on WhatsApp →Selling on EMI shouldn’t mean losing the phone.
Once a financed phone leaves the counter, most shops are left hoping. emidost turns that hope into a system — every device tracked, every due date clear, and a safe, built-in way to pause an overdue phone until it’s paid.
Financed phones you can no longer see once they leave the counter
EMI schedules and due dates tracked in a notebook or a chat
A missed instalment, and nothing but a phone call for leverage
Overdue devices with no safe, built-in way to pause them
From EMI sale to paid-off device
One continuous flow at the counter. Each financed phone moves through the same lifecycle, and emidost keeps hold of it the whole way.
- Step 1
Customer
A buyer picks a phone and agrees to an EMI plan at your counter.
- Step 2
Device registration
Enrol the phone as a managed device — IMEI and plan linked to the customer.
- Step 3
EMI schedule
Months, amount and due day are recorded against the device.
- Step 4
Payment tracking
Mark each instalment. See exactly what is paid, due and overdue.
- Step 5
Device status
Every financed phone and its live state, from one device list.
- Step 6
Lock / unlock
Overdue phones lock to the payment screen. Paid phones unlock on their own.
Built for the real world — even when the internet isn’t.
Patchy data shouldn’t be a loophole. emidost keeps working at the edge of the network, so a financed phone stays under the agreement whether it’s online or not.
- Enforcement runs on the phone itself, not a live server check.
- Stay offline past the limit and the phone locks on its own.
- Authorized lock and unlock commands can arrive by SMS with no data.
- Payment reminders keep playing on the phone while it is offline.
To stay precise: syncing the dashboard and recording payments uses the retailer app when you’re connected. The on-device lock does not need the internet to hold.

Watch a financed phone move through its states
Normal while payments are on time. One clear screen when they’re not. Back to normal the moment the instalment is recorded. Tap a stage to see it.
Every financed phone, on one screen
The retailer app gives your shop a live view of every device you’ve financed — customer, EMI progress, due date and lock status — so overdue accounts never slip past you.
Enforcement that stays on the phone
emidost holds a financed device the way the operating system intends — at the device-owner level, not as an app a customer can swipe away.
Device Owner architecture
The app enrols as the phone’s device owner — the operating system’s own manager, not a removable overlay. The menu factory reset is blocked.
Reboot persistence
A restart does not clear the state. If a phone was locked, it comes back locked.
SIM-removal protection
Pulling or swapping the SIM triggers a lock within seconds, so the agreement cannot be dodged offline.
Offline safeguards
Enforcement runs on the phone. Stay offline too long and it locks itself — no server call needed.
Authorized commands
Lock and unlock are authenticated actions tied to your account and the financed device. Command details are never exposed publicly.
A fair exit, always
Emergency 112 stays reachable on the locked screen, and a settled loan never locks again.
We describe what the product does, never how to defeat it. Command formats and account secrets are kept out of public materials by design.
Set up at the counter, no computer needed
One enrolment per phone. After that, the device protects the agreement on its own.

Questions retailers ask
What is EMI phone lock software?
It is software a mobile retailer uses to sell phones on EMI and keep each financed device secured until the instalments are paid. emidost tracks the EMI schedule and can lock an overdue phone to a payment screen, then unlock it the moment the payment is recorded.
How does an EMI mobile lock work?
During the sale, the phone is enrolled as a managed device and linked to the customer’s EMI plan. While payments are on time the phone is completely normal. If an instalment goes overdue, the phone locks to a single payment screen until the instalment is recorded.
Can an EMI device lock work without internet?
Yes. The enforcement runs on the phone itself, so it does not depend on a live connection. If the phone stays offline too long it locks on its own, and lock or unlock commands can be delivered by SMS when there is no data.
Can a retailer lock a phone remotely?
Yes — for devices you have financed and enrolled, under your agreement with the customer. You trigger the lock from the retailer app, online or by SMS. emidost only manages devices you have registered, never arbitrary phones.
How does unlocking work after payment?
You record the instalment in the retailer app and the phone unlocks on its own within seconds. There is no computer and no cable involved. A fully settled loan is released and never locks again.
Does emidost work on Android?
Yes. emidost supports Android 11 and above and the major smartphone brands sold in India. An enrolment wizard carries the per-brand setup steps so counter staff never have to guess.
What happens if the customer removes the SIM?
Removing or swapping the SIM triggers a lock within seconds. This stops a financed phone from being taken offline to avoid the agreement.
Does the lock survive a reboot?
Yes. Restarting the phone does not clear its state. If the device was locked, it returns locked after the reboot.
Can a customer bypass the lock with a factory reset?
From the settings menu, no — device owner mode blocks it and the lock returns after a reboot. One limit, stated plainly: a recovery-mode wipe using a computer can reset the phone, after which factory reset protection asks for the enrolled account. No phone software can block that entirely, and we do not claim otherwise.
Is emidost built for mobile retailers?
Yes. emidost is made for mobile shops and device financing businesses that sell smartphones on EMI. The whole workflow — enrolment, EMI tracking, lock and unlock — is designed for the counter.
How does SMS-based device control work?
When a financed phone has no data connection, authorized lock and unlock instructions can reach it over SMS instead. The command itself is authenticated and tied to your account and the specific device.
Can retailers manage multiple financed devices?
Yes. The retailer app and dashboard list every financed device with its customer, EMI progress and live status, so a shop can manage many phones at once and spot overdue accounts at a glance.
