A SIM can get deactivated if it is not being used for more than 90 days. That is no outgoing or incoming calls/messages/internet access or any kind of VAS subscribed on that network. The only thing you can do is call 198 Toll free and enquire with the Vodafone authorities.

Assuming you set up voicemail, one of the easiest ways to establish if your line is active would be to call your number. If you get your voicemail message, then all is well.
Also, assuming you set it up while you had the SIM on a network, you could log into the provider's web portal to see if the account is still active. Usually this requires access to receiving SMS messaging, so if you have roaming disabled, you probably won't be able to enable this until you are in native coverage again.

If you remember which all proofs you have submitted during taking that sim from India, please share it with anyone(friends or relatives in India) and ask them to call the Vodafone customer care of your home town. If they could provide the valid information to customer care executives, you can know whether your sim is active or not.
