FreeUP Mobile's 8GB plan for 1 line costs $20 per month.
It rides on the AT&T network for coverage.
It includes unlimited minutes, unlimited texts, and 8GB of high-speed data per month. After your high-speed allotment, you get unlimited slow data at Unknown. Unfortunately, you do not get any hotspot data with this plan. Video streams at 4K quality.
The FreeUP 8GB Annual plan has deprioritized data. Having deprioritized data means you may temporarily experience slower speeds during times when the cellular network is busy. You'll resume getting the fastest speeds available when the network is no longer busy.
Overall, I recommend the FreeUP 8GB Annual plan because it is a good value.
