Plan lengths

T-Mobile prepaid runs one month at a time. With 3 months, month 1 starts when you activate; we add month 2 and month 3 to your line when each one is due. They are already paid — nothing more to pay.

Add-on: Mexico & Canada (+$5/month)

Unlimited calling to and from the U.S., Mexico and Canada. Bonus: unlimited texting to 215+ countries and destinations while in the U.S., Mexico and Canada.

Activate in 3 steps

1. Put the SIM in your unlocked phone (or choose eSIM — we email you the steps).
2. Go to activation.tamprime.com.
3. Enter the SIM number. Your paid plan is applied automatically.

Good to know: each month is 30 days of service. Your phone must be unlocked and compatible with T-Mobile. eSIM needs an eSIM-capable phone. Coverage, speeds, activation and number transfer depend on T-Mobile's rules, network coverage, your device and account eligibility.
