What you can do

• Avoid using your T-Mobile number for non-T-Mobile contests, promotions, or newsletters.
• Never download applications from unauthorized app stores.
• Do not swap applications with friends using memory cards.

When buying a used phone:

• Purchase from a reputable retailer or manufacturer. T-Mobile offers great prices on certified pre-owned phones.
• Make sure the phone has been cleared. If you find any information stored in the phone, it may not be safe.
• Check the device's IMEI hasn't been reported stolen on the Cellular Telecommunications and Internet Association free stolen phone checker tool​.

Calling T-Mobile

• Make sure the only authorized users on your account are people you want to have access to information and make account changes.
• Set up your Customer PIN/Passcode for when you call T-Mobile.
• T-Mobile will never call you to ask for or verify your personal information unless you contacted us first.

My T-Mobile

• Have user permissions on My T-Mobile set up for each line on your account.
• Change your T-Mobile ID password and security questions every few months.
• Turn on two-step verification for extra security.

Calls

One Ring Call back scam is when an incoming call rings once before hanging up. You get a call from a number that looks like it from the US but is not. For example, "649" goes to the Turks and Caicos and "809" goes to the Dominican Republic. Calling these numbers back may incur charges on your T-Mobile account.

Tips to avoid these scams

• Turn on Scam Block.
• Don't answer or return any calls from numbers you don't recognize.
• Beware of callers from unknown numbers who immediately ask, “Can you hear me?” Disconnect or answer, “I can hear you.”
  • If you say ‘yes’, the caller could record your response and reuse it elsewhere.
• Before calling unfamiliar numbers, check to see if the area code is international.
• If you do not make international calls, you can Contact Us to

Messages

• Don’t act on any message if you're suspicious of the content, even if it looks like it's from someone you know.
• Never click on a link in a text message unless you're certain that the message is from a trusted source.
• If you have opened a suspicious link, change your T-Mobile ID password ​and other personal accounts, like banks and social media.

Text message (SMS) spam is any unwanted texts, often from companies, news sources, banks, restaurants, etc, you may receive. SMS spam should not be confused with Self-service short codes, which includes T-Mobile short codes that we use to keep you informed about your account.

  • After opting out, you may receive one more message confirming your request to opt-out.
