No cellular signal after 5.0.2 update

[Delicon]

After updating my Z2 (D6503) to Lollipop I got 'Invalid card' and no mobile signal, once in 1-2 days.

After rebooting the phone everything is fine but just for 1-2 days.

I've tired factory reset and pc companion repair but without success.

I'd suggest getting a new SIM card replacement, especially if your card is self-cut into microSIM.

I dont' think that it's sim card problem, because after restart it works fine.

If the sim card is somehow removed the phone will restart immediately.

I have escalated this issue as a few members are reporting the same thing so for now we have no surefire way to fix the issue you and others have

I would ask the user to try:

- Switch network mode to check if it might be an issue with a certain network

- Try manually selecting the right network (it might already be set on manual causing issues)

- Check with the operator if they are aware of any network issue

- Try another SIM-card

- Repair the phones software

- If possible, try another operator

If the above fails then you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/
