Xfinity Mobile's 30GB plan for 1 line costs $40 per month.
It rides on the Verizon network for coverage.
It includes unlimited minutes, unlimited texts, and 30GB of high-speed data per month. After your high-speed allotment, you get unlimited slow data at 1.5Mbps. You get 600Kbps of hotspot data. Video streams at 480p quality.
It is worth noting that the Xfinity Mobile Unlimited plan includes priority data. Having priority data means you will get slightly faster data speeds during times when the cellular network is busy, such as at sports games, concerts, or during rush hour traffic.
Taxes and fees are extra on this plan. I estimate they will add another $4.80 to the price. Your total montly bill will be about $44.80 per month.
Overall, I do not recommend the Xfinity Mobile Unlimited plan. It is too expensive for the features and data you get.
