Boom Mobile's 4GB plan for 1 line costs $17.99 per month.
It rides on the T-Mobile network for coverage.
It includes unlimited minutes, unlimited texts, and 4GB of high-speed data per month. The data is shut off after you reach your high-speed allotment. You can use up to all 4GB of data as hotspot data. Video streams at 4K quality.
The Boom! Purple 4GB 3-Months 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.
All taxes and fees are included, so your grand total is just $17.99 per month.
Overall, I do not recommend the Boom! Purple 4GB 3-Months plan. It is too expensive for the features and data you get.
