Vodafone Reliance sim cards in China

Does Vodafone India and Reliance India sims work in Suzhou when kept in International Roaming mode?

I want to confirm this because I am planning to bring them to Suzhou as I will be getting OTPs (One Time Passwords) to these phone when operating on any Indian online bank accounts and other online accounts. If I bring them to China and they don't work there (China), then it would be a disaster for me and in such case it is better to keep them in India and ask some one at home (India) to operate and check the messages received (I can call and ask them through phone call from China).

Any suggestions on what to do with my phones? Should I bring them China or leave them home (India)?

Thanks.

I went to Vodafone store and I was told that Vodafone will not have network/tieup in China.
