What is an Ultra Mobile SIM card and how does it work?
An Ultra Mobile SIM card is a removable card that identifies your device on a mobile network, allowing you to make calls, send texts, and use data. It operates on T-Mobile's nationwide network, providing 5G coverage to 98% of Americans and 4G LTE coverage to 99%. The core value proposition is prepaid plans with no long-term contracts that include unlimited talk and text from the U.S. to over 90 international destinations, so you don't need separate calling cards or apps to reach family overseas.
Ultra Mobile plans: data, duration, and international features
Ultra Mobile offers flexible prepaid plans with durations of 1, 3, 6, or 12 months, with multi-month plans providing lower monthly costs. Most plans with 4GB of data or higher include monthly international call credits and a one-time international roaming credit. Unlimited plans typically offer 35GB or 40GB of high-speed 5G/4G LTE data per month before speeds may be deprioritized during network congestion.
Choosing between a physical SIM and an eSIM
You can choose between a physical SIM card (a 3-in-1 universal size kit that fits standard, micro, and nano SIM slots) or an eSIM for instant activation without waiting for a card to arrive. Both options require an unlocked, 4G VoLTE or 5G compatible phone. If you prefer a physical card you can swap between devices, the 3-in-1 kit is your best bet; if you want to activate immediately and keep your physical SIM slot free, the eSIM is the way to go.
How to activate your Ultra Mobile SIM card
To activate online:
- Go to my.ultramobile.com/activation and click the image of your SIM type (Orange or Purple).
- Enter the 11-digit activation number found on your SIM card kit.
