Hi @Jambo87, I am very sorry to hear about that. 
First I would recommend that you try what @Viridis suggested in trying a different SIM to see if the same occurs; in addition - does your device reboot when you eject the SIM while the device is turned on?
If you have the SIM inserted and go to Settings > About phone > Status > SIM status, does it say not available here for all the entries?
Let me know how it looks and I'll do my best to assist you.
Yes,in about phone>status>sim status all the entries are showing not available
