No Service on iPhone 6 running ios 8.2

Hi:

I noticed this issue only about 18 hours back. I did a factory reset and that has not helped. It is not an issue with the carrier or the SIM card as the same SIM is working fine on other devices. When a working SIM card from another device is inserted into this iPhone 6, I still have the No Service issue. I had upgraded to ios 8.2 several days back and had faced no issues up until now.

Please advise.

TIA,

Niv
