Straight Talk's Unlimited plan for 4 lines costs $140 per month.
It rides on the Verizon network for coverage.
It includes unlimited minutes, unlimited texts, and unlimited high-speed data per month. You get 15GB of hotspot data. Video streams at quality.
The Straight Talk Gold Unlimited 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 do not recommend the Straight Talk Gold Unlimited plan. It is too expensive for the features and data you get.
