Sceen blinks with all swich-lights on and shows Inactive SIM message


My Sony Ericsson w700 is showing unexpected behaviour.

After every 4-5 min, cell stops resopnding, screen becomes black, all button-lights turns on. After few seconds cell shows - Inactive SIM.

After few min, cell again comes to normal state. This happens after every 10-15 min.

Please let me know what can be the problem and solution for this.

PS: I've tried updating firmware using online updater software. But problem still persists.

Thanks in advanced.

After reflash the firmware and you are still having the problems then take the phone and have it either replaced if the warranty is still valid or you will have to buy a new mobile..

I have a w850i and the sceen shows emergency calls

1. It's a common problem with Sony Ericsson W850 phone!

2. It displays the 'Emergency Calls Only' message even the network is available. (Mainly due to the change in the frequency of the signals!)

3. You should try to update the phone OS/Firmware.

4. If it don't helps try to reinstall the OS software!

please rate this advice if it! :)

Phone saying inactive sim its a k850i sony ericson

I assume you did not purchase the phone from a eputable source. The inactive sim message appears in this way when a person reports a sony ericsson phone lost or stolen. The IMEI number (unique to every handset) is used to disable functions of the sim reader.

Inactive sim

This is a known design flaw with the w760i - it occurs when the phone requests info from the SIM (building contact list etc.) and the SIM connection is lost. This would happen on any phone but the w760i has a shock protection design issue whereby closing the slide quickly causes the SIM to disconnect. You should be able to replicate the issue by turning the phone on and slamming the slider shut as soon as the phone shows your network name. Leave the phone on for a bit and you will feel the phone buzz and 'Inactive SIM' will display, the phone will then reboot.
