I have BSNL evdo postpaid unlimited plan with zte AC8700 device, i have been using it for more than 5 years now!!!

Now i want to terminate its services temporarily, As me and my family are going for vacation overseas for 2 months i won't be able to use it! And since it is a post paid it keeps generating internet bills eventhough i'm not using it!

I would like to resume connection with same unlimited plan after i return! Can anyone let me know what are the procedures to do it!? And is it possible?

I already asked to nearby bsnl collection office, but they are not responding properly!

please help me with this!

Thanks in advance for your reply
