My company is working over Whatsapp project on C#.net. We have found a major problem of channel blocking. Our most of channel has been blocked . So how can we minimize channel blocking. And One more concern is that after 5 sim registration , we have found a lot of problem to register a new channel. So how can we resolve it both problems.
