Metro by T-Mobile's Unlimited plan for 2 lines costs $50 per month.
It rides on the T-Mobile network for coverage.
It includes unlimited minutes, unlimited texts, and unlimited high-speed data per month. Unfortunately, you do not get any hotspot data with this plan. Video streams at 480p quality.
The Metro by T-Mobile Unlimited (New Customers) 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 $50 per month.
Overall, I recommend the Metro by T-Mobile Unlimited (New Customers) plan because it is a good value.
