UP
Our takeEditorial
Pay-per-GB that rewards light use and punishes regularity. Under 3 GB/mo it's clever; at 6 GB/mo the bill can hit $80 before taxes.

The Optimist
“International data in 200+ countries at no extra charge - no other US MVNO at this price matches that.”
— the angel on your shoulder
The Cynic
“A moderate 6 GB month costs $80 before taxes - more than unlimited plans on the same T-Mobile towers.”
