Nokia 1100
Vodafone network problem

I am using Nokia 1100 handset for many years with BSNL, Reliance and lastly Airtel connections. But now I have been ded Vodafone sim card by my employer. Surprisingly no network connection shows in my handset. I have inserted the sim in other models and it works. Can you please tell me whether Nokia 1100 and Vodafone does not support each other and how to solve this problem.
