HMD has officially acknowledged an issue that occurs after the installation of Android 10 on some of the Nokia 7.2 Dual-SIM variant devices. If one of the SIM is disabled of deactivated then the device may not start properly and may enter Recovery mode.
As mentioned in the discussion Single-SIM devices are unaffected and HMD claims that only a limited number of Dual-SIM devices are affected.
Please follow either of two options below to recover your device to normal state (with no loss of user data):
If you do not wish to continue to use the Disabled SIM
- Power off the device
- Remove the Disabled SIM
- Power on the device
If you wish to continue to use both SIMs
- Power off the device (or if in recovery mode, “Try again”)
- Ensure both SIM1 and SIM2 cards are inserted
- Power up the device (Important notice for users with Roaming SIM card who not want data Roaming enabled – Please go to “Settings” > “Network & Internet” > “Mobile Network” > Mobile network [SIM name] > [SIM name] and check that Roaming is set to Disabled)
- Go to “Settings” > “Network & Internet” > “SIM cards”, and activate any deactivated SIM card (you may need to try a couple of times and wait for a few minutes for connection. If after several minutes, you do not see successful connection to the network, then a restart may be required).
