Lock and unlock a phone

If the customer doesn't pay, lock the phone — while locked, the customer can only use the phone to call you and pay the installment. Once you get the money, unlock it again with one tap.

📍 Where to find it: The Command Center section on the phone's page, or the Restrict / Restore buttons in the Devices list.

📷 Screenshots show the panel in Bangla — switch the panel to English and the same buttons appear in English.

Step by step
  1. Open the phone's page.
  2. In the Command Center, you can write a notice to show on the lock screen (for example: “Installment due — please contact the shop”).
  3. Tap Lock (freeze). If the phone is online, it locks immediately.
  4. When you get the money, tap Unlock in the same place.

💡 Good to know
  • Send the lock even if the phone is offline — it locks as soon as it gets internet. If it's urgent, use Send by SMS.
  • To lock automatically when an installment date passes, see Lock Rules and the installment settings.
