It depends on which VPN service provider you have chosen. Some of the VPN services do limit the total data for sending and receiving, specifically in either of the two ways – in one connection session or in a month. Other VPN services limit the data speed by effectively sharing less data pipe with you. This slows down your browsing experience to a crawl or even wholly prevents your access to the streaming videos. These issues occur with the free VPNs or with the paid VPNs whose trials you are currently in.
