In late May of 2019, T-Mobile announced it would be re-branding it's cellular plan line-up from 'ONE' to 'Magenta'. This rebrand brought few changes to the actual plans being renamed - other than an additional 3GB of high-speed mobile hotspot data being added to the base ONE Magenta plan, and a downgrade in Netflix services for the lines. Here is our story on the changes: T-Mobile Rebrands ONE to Magenta

• T-Mobile ONE+: $80/Single Line
  • ONE+ 'AMP UP' - smartphone and tablet plans include unlimited talk, text, and on device data. The '+ AMP UP' adds 20GB of high-speed mobile hotspot data to the ONE plan, then unlimited 3G speed mobile hotspot data. HD video is also permitted.
• T-Mobile ONE: $70/Single Line
  • Smartphone and tablet plans include unlimited talk, text, and on device data. Mobile hotspot data is unlimited at 3G speeds.

Policies & Perks

• Carrier Networks Used: T-Mobile
• Carrier Relationship: Direct
• Plan Types Available: Phone (unlimited talk/text), tablet
• Devices Permitted: Phone, tablets
  • Hotspot devices are not eligible to be added to any of T-Mobile's current Unlimited plans.
  • Tablets can be added to any unlimited plan for $20/line.
  • Tablets can be added as a singular device on a ONE plan (no other phone devices on the plan) for $75/month.
• Device Purchase Required: No
• Mobile Hotspot / Tethering:
  • Global Plus 15GB: includes unlimited 4G/LTE high-speed mobile hotspot use while in the US. On-device data speeds are prioritized over mobile hotspot speeds, so on congested towers there may be a noticeable performance hit for mobile hotspot.
  • T-Mobile ONE+: adds 20GB of high-speed mobile hotspot use, then unlimited mobile hotspot at 3G (512kbps) speeds. On-device data speeds are prioritized over mobile hotspot speeds, so on congested towers there may be a noticeable performance hit for mobile hotspot.
  • T-Mobile ONE: unlimited mobile hotspot at 3G (512kbps) speeds. On-device data speeds are prioritized over mobile hotspot speeds, so on congested towers there may be a noticeable performance hit for mobile hotspot.
• Network Management / Throttling:
  • Global/ONE/+ plan customers who are in the top 3% of heaviest users on T-Mobile (currently those using 50GB/mo) are subject to network management once they have crossed this monthly threshold, which means that their ongoing usage will be slowed down relative to other T-Mobile customers - but only when towers are congested.
• International Roaming:
  • Global Plus 15GB
    • Can be added to a line for $50 add-on/month option and is available for customers on a postpaid T-Mobile One/One+ plan only. With Global Plus, customers get 15GB high-speed data on device while roaming in a Simple Global country (only 5GB in Canada/Mexico) and 5GB of high-speed tethering usage in Simple Global countries. Additional features include unlimited HD video streaming around the world, and unlimited in-flight Wi-Fi.
  • ONE/+
    • Mobile Without Borders - Canada & Mexico: All T-Mobile ONE plans can be used anywhere in Mexico & Canada just as if you were at home, including tethering! However, data usage is capped to just 5GB per month of combined usage in Canada and Mexico. And T-Mobile does reserve the right to enforce a policy that the plan needs to be used 'mostly' in the USA. Essentials plan only include 128 kbps speeds over the borders.
    • Simple Mobile - Rest of the World: T-Mobile ONE plans include free unlimited international text messaging, and free unlimited data in over 210 counties internationally at a slow (but useable) 128kbps speed. T-Mobile also has reasonable rates for voice calls too. Having ONE+ bumps you up to 256kbps speeds.
    • Day Passes - T-Mobile offers $5 days passes for 512mb of high-speed data, then unlimited 2G speed data for 24-hours in their international roaming countries. A max of 2 day passes per 24-hour period may be purchased.
• Domestic Roaming: After 200mb of domestic roaming data usage, T-Mobile cuts off roaming network usage until your next billing cycle, or until you're back in a native area on all plans.
• Data Roll Over: N/A
• Overage Charges: None - unless you request 'add-ons' such as 'day passes.'
• Streaming:
  • Video Perks:
    • ONE/ONE+ plans with at least two lines are provided with a free basic Netflix account.
  • Streaming Restrictions:
    • The base ONE plan is restricted 480p video resolution.
    • However, upgrading to ONE+ (AMP UP) allows for full HD (1080p) resolution video streaming.
    • Canada & Mexico: While usage is still unlimited in these countries, video will be throttled down to 480p.
    • Global Plus 15GB includes 1080p video streaming around the world.
• Taxes & Fees:
  • ONE/+ plans are flat priced and inclusive of taxes & fees.
• Other Plan Perks:
  • Gogo Inflight Wi-Fi:
    • ONE plans include one hour per flight of free Gogo access to get a smartphone online.
    • Those on ONE+ can add unlimited Gogo usage and a few other perks for an additional fee.
    • Adding Global Plus merits unlimited in-flight Wi-Fi.
  • T-Mobile Tuesdays
  • T-Mobile MONEY

On August 10, 2018 rolled out the Essentials plan, and increased the price & hotspot use of ONE+. They also snuck in the retirement of ONE+ International.

Those who had ONE+International or ONE+ active as of 8/9/2018 are now grandfathered in under these terms:

• ONE+ International (+$25/month on top of One): Unlimited 4G mobile hotspot use and not subject to the Canada/Mexico 5GB/mo cap. However, the carrier reserves the right to de-prioritize mobile hotspot use under on device use, and high data users who are primarily using the plan for tethering may be contacted by the carrier to discuss options (this seems to be an issue if you consistently consume more than 50GB of total data per month and over 50% of your usage is mobile hotspot). International use beyond North America is at 256k speeds, with $5 day passes available for high-speed use.
• ONE+ (+$10/month) - This option included 10GB of high-speed mobile hotspot use per line and HD video.

T-Mobile began phasing out Simple Choice plans in September 2016, and eliminated them in January 2017. However, they have gone on record that they will grandfather these plans for as long as customers keep paying their bill. These plans had tiered high-speed data caps, Binge On unlimited video streaming and Data Stash.

In particular, we regularly recommended the $35/month 6GB data only plan.

Policies & Perks

• Carrier Networks Used: T-Mobile
• Carrier Relationship: Direct
• Plan Types Available: Data only
• Devices Permitted: Hotspot, tablet, phone
• International: Binge On video streaming is not included outside the USA. Simple Choice customers can purchase pricey Data Passes for 3G international speeds for outside of North America.
• Mobile Hotspot Use: T-Mobile plans include mobile hotspot use, however, they do prioritize on device data over tethered / mobile hotspot data on all smartphone and tablet plans when on congested towers.
• Data Roll Over: Any high-speed data you don't use is rolled over into 'Data Stash' for up to a year. You can accumulate up to 20GB in this account, to use when you need it.
• Overage Charges: T-Mobile never charges overage fees. Once you hit your high-speed data cap, you are simply slowed down to 2G speeds for the rest of the billing period.
• Streaming:
  • Simple Choice - Binge On! All Simple Choice plans (postpaid) with 6GB of data or more include video streaming that does not count against your high-speed data cap on partnered networks (including Netflix, Hulu, Amazon Prime, HBO Now, YouTube, etc.), but at DVD-quality lower resolution. It officially only works on-device or when tethered to a laptop - but many have reported success using the service now with Roku, AppleTV, Chromecast, FireTV, etc (be sure to carefully watch your data usage!)  They also include free music streaming over many services. (Note, their Prepaid plans do NOT include the video streaming.) Binge On usage does count towards network management thresholds and is subject to slower speeds for high usage customers when on congested towers after using 32GB of data in a month.
