Smart ultra 6

[Diron]

Why is my smart ultra 6 overheating and brings up the message no SIM card emergency only so that I have no mobile network.

Has anything happened recently @Diron like a firmware update or you've downloaded any apps recently ?

May i ask....

Have you tried a soft reboot by turning the phone Off and On. 

Does your Vodafone Sim Card work Ok in another phone ?

As a last resort a Back-Up and Factory Reset may help. 

To add the phone will have a 24 Month Manufacturing Warranty so any Vodafone Highstreet Store can send it off for a diagnostic. Again create a back up as they typically reset it.

Thank you.yes I have tried switching it off and then back  on once it has cooled down I don't have a problem,but unfortunately after a while it heats up again and does exactly the same thing again.

You're Welcome @Diron

So as a soft reboot isn't working then if this was my phone the next step would be a Factory Reset.

Ok, thanks for you help.
