Hi. I'm planning to buy BSNL Wings account. Can I use the same account on two different devices at a time. I want in such a way that one device will be in my office and another in home. If there's an incoming call, both devices should ring and if one device is answered, another one drops. Just like having two landline phones in the same house. Is it possible or BSNL restricts using one account in one device at a time?
