Using Mobicip should not have a significant impact on your data usage. The way Mobicip works is by re-routing your Internet traffic to go over Mobicip's cloud servers, where the content is filtered. The amount of data transferred should be no more or no less than when you go on the Internet directly without using Mobicip. If you see any significant difference, please provide any evidence you can find. If the issue is conclusive and reproducible, our engineers will investigate the problem and fix it for sure.
