No, NordVPN does not have a data limit or block any traffic. In addition, it does not throttle or limits bandwidth at all, so you can be confident that your speeds won't change when you use our service. If possible, we always recommend connecting directly to an ethernet port on your router instead of Wi-Fi if you want optimum speed and performance from any device connected to your home network (including routers). This will ensure that nothing gets in between you and whatever website or content you are trying to access with NordVPN!
