Cellular connections are not the best option; however, if you are a streaming game, then you must get an internet connection. Twitch streaming depends on the speed of the internet, so you must look for internet with almost 25mbps speed. Although, the ideal speed is 15 to 20 Mbps, but you must choose at least 25mbps. Beware of the companies which do not tell you about the uploading speed. However, it is only enough for 720p resolution, for a higher live-streaming video quality you must choose 25 Mbps or higher internet speed
