Criminals send fake T-Mobile notifications about mandatory eSIM upgrades or attractive international roaming bundles, using them to hijack phone numbers or collect fraudulent payment.
Part of: Fake eSIM & Roaming Scams
Last reviewed: 7 June 2026
T-Mobile has been at the forefront of eSIM adoption in the United States, and many T-Mobile customers are familiar with the concept of digital SIM management. Scammers exploit this familiarity by sending fake T-Mobile notifications claiming customers must urgently migrate to an eSIM or that a pending eSIM transfer is awaiting confirmation.
T-Mobile also offers popular international roaming plans under its Magenta and Go5G offerings, including its 'International Day Pass' and unlimited international data on certain plans. Fraudsters create fake T-Mobile promotional pages offering discounted international bundles, particularly targeting customers ahead of international travel.
Both types of attack use T-Mobile's magenta branding and mimic the T-Mobile app's notification style to appear credible.
How this scam works on the T-Mobile brand
The fake eSIM migration message typically arrives by text, appearing to come from T-Mobile's short code, claiming that the customer's account has a 'pending eSIM activation' or that their SIM card will stop working unless they confirm the migration via a provided link. The link leads to a fake T-Mobile login page or a page that instructs the victim to call a number where a fraudster authorises a real SIM swap.
Fake international roaming promotion pages appear in search results or social media ads around holiday and summer travel seasons. They offer an attractive day-pass rate or unlimited international data plan that must be purchased through the promotional link. The site collects card details and charges the card, but no plan is ever added to the customer's account.
T-Mobile's legitimate eSIM management and plan changes are handled exclusively through the T-Mobile app, at t-mobile.com, or by calling T-Force via social media or 611.
Common red flags
- An unsolicited text or email about a pending eSIM migration not initiated by you
- A link in a T-Mobile message leads to a domain other than t-mobile.com
- An international roaming plan is offered via a link in a text or social media ad at a price significantly below official T-Mobile rates
- The message asks you to call a number not listed on t-mobile.com
- Urgency framing: 'Your SIM will be deactivated in 24 hours'
- A caller who claims to be T-Mobile asks for your account PIN and a one-time verification code
How to protect yourself
- Manage eSIM and plan changes only through the T-Mobile app or at t-mobile.com — never via unsolicited links
- Enable T-Mobile's Account Takeover Protection in the My T-Mobile app to restrict SIM swaps to in-store only
- Contact T-Mobile support at 611 or via T-Force social channels if you receive an unexpected eSIM notification
- For international roaming, compare plan options only at t-mobile.com/coverage/international
- Never share a one-time SMS code with anyone who contacts you — T-Mobile will not ask for this over an inbound call
How to report it
- Forward smishing texts to 7726 (SPAM) to report them to T-Mobile and the FCC
- Report phishing and fraud at t-mobile.com/responsibility/privacy/report-phishing
- File a complaint with the FCC at consumercomplaints.fcc.gov and the FTC at reportfraud.ftc.gov
- If your number was swapped, call T-Mobile at 611 immediately and ask the fraud team to reverse the transfer
Frequently asked questions
Does T-Mobile send texts requiring me to confirm an eSIM migration?
T-Mobile does send notifications about eSIM options, but it does not send unsolicited texts requiring urgent confirmation of a migration you did not initiate. Any such message should be verified directly in the T-Mobile app before taking action.
What is T-Mobile's Account Takeover Protection?
It is a free feature that requires you to visit a T-Mobile store in person with a valid photo ID before a SIM swap can be completed on your account, making remote SIM swap fraud much harder. Enable it in My T-Mobile under Security.
