BB stopped sending nor receiving chat last night, the mobile network was observed to have network mode missing. What can I do?

Reset your blackberry to default factory setting, and if not working try to unlock your blackberry network using blackberry curve 8520 unlock code for your original network sim card. You can get blackberry unlock code from your network provider or buy at third party sites. Both of them will need you to pay some cash, but third party sites has lower cost rather than network provider.

'Insert SIM'

If you are trying to use an old sim-card from another phone you may find that it won't recognize it.

The older sim cards just aren't up to the job the newer handsets require so now we have more powerful and higher voltage sim-cards.

Try a sim card from a friend with a new handset and see if that works in your phone.

You may have to go get a new sim.

I want to copy my contacts from my blackberry 8520 to my sim card

Unfortunately you can only copy them one-by-one...go to your address book, select the contact you want to copy, click the menu button and select "view"...then press the menu button again and select "Copy to SIM Phone book", this option is the very first one up.
