Plan Quality Signals These meters highlight clarity, restrictions, feature depth, and how useful the plan is for travel.
Think of this as the fine-print section: it shows whether the plan is easy to understand, light on caveats, and strong enough for travel or international use.
Data Truth 92
The marketed data claim lines up well with the plan's real monthly limits.
Feature Completeness
?

Feature Completeness measures how many useful plan-level features are confirmed, such as hotspot support, priority data, travel and roaming support, device and SIM type support, data rollover or top-ups, international options, and included perks. Higher scores mean more confirmed extras; lower scores mean fewer supported features or more unknown details.

 61.8
This plan includes a decent set of confirmed extra and supported features.
Caveat Load
?

Caveat Load looks at fine-print and signup friction, including whether taxes and fees are included in the advertised price or charged extra, autopay requirements, contracts, credit checks, activation/SIM/shipping fees, and online-only or store-only rules. Higher scores mean fewer caveats were found; lower scores mean more caveats or unresolved caveat details. When Carrierlytics cannot verify a caveat because the carrier is not clear or because we have not captured it yet, a small uncertainty penalty is added instead of assuming there is no issue.

 55.1
Several caveats may affect the real cost or signup experience.
Travel Value 55
Travel benefits are usable, but not a defining advantage.
International & Roaming
Canada/Mexico roaming Add-on

A $5 add-on will get you unlimited calling and texting to and from Mexico and Canada and possibly 5GB of high-speed data to use while traveling in either country. T-Mobile Prepaid's website gives out contradictory information about whether or not the data is included with the add-on or not.

Global roaming Not available
Call international numbers from US Add-on

For $15/mo you get unlimited calling while in the USA, Canada, or Mexico to landlines in 70+ countries and mobile lines in 30+ plus international texting.

Text international numbers from US Add-on
Device Support Tablet and smartwatch support, including add-on pricing when confirmed.
Tablet support Add-on

Tablet plans are available and start at $10/month for 2GB high-speed data then not really usable and limited to 128Kbps. The flagship tablet plan available with this phone plan costs $50/month for 50GB 5G data before throttling.

Smartwatch support Not available
