T-Mobile prepaid plans put two data descriptions on the 1-line card. The card lists 15GB of high-speed data and unlimited talk and text, at $40 a month for 1 line with AutoPay, and $45 for the first month plus taxes and fees. The facts label on that same card says the data included with the monthly price is unlimited.
What the other cards add
A 10GB plan lists 10GB of 5G data and unlimited talk and text. Its facts label says 10GB of high-speed data, then unlimited at 128kbps. The 2-line, 3-line, and 4-line cards print 15GB of premium data with unlimited 2G speeds after, and the facts label on those cards says unlimited. The 3-line card is $100 a month with AutoPay and $105 the first month plus taxes and fees. The 4-line card is $130 a month with AutoPay. Those monthly prices are separate cells. They are not one blended rate.
One plan block lists unlimited 5G data, unlimited talk and text, and unlimited talk and text to and from the US, Mexico, and Canada. Further down, Mexico and Canada calling is also offered as an add-on at $5 a month. That add-on and the included block are different lines.
Where this row sits
Taxes and fees sit outside the first-month prices above. The state comparison records government taxes as varying by location, on US phone plans in Massachusetts. A prepaid line and a credit check are separated on getting a US phone plan without an SSN.
