Understanding Robocalls

  • A robocall is a phone call that delivers a pre-recorded message and not a live person.
  • No, some robocalls are positive (e.g. appointment confirmations). A few types of robocalls are allowed under the Federal Trade Commission (FTC) rules without your permission (e.g. charities asking for donations, political calls about candidates running for office).
  • A positive robocall presents no harm to subscribers, and some may even be wanted or needed. Examples include public service announcements, appointment confirmations and prescription refills.

    A nuisance robocall isn’t illegal or indicative of malicious intent, but might be a call that customers don’t want to answer all the time. Examples include promotional offers, solicitation and accounts receivable.

    A high-risk robocall of includes loss of money, invasion of privacy and identity theft. These callers are trying to gain a caller’s trust to prey on them.
    • Spammers place automated phone calls in a manner that is in willful non-compliance with state and federal laws governing the use of automated dialing.
    • Spoofers knowingly transmit misleading or inaccurate caller ID information. These calls may be placed manually or through an auto-dialer. Spoofers often use various methods to mask their telephone number in order to show a completely different number, often a number that may be local or familiar to you.
    • Scammers disregard state and federal laws to make calls with the intent of committing identity theft or other types of fraudulent behavior.
  • One-ring robocalls trick you into unknowingly making international toll calls, which can add hundreds of dollars of charges to your account. One-ring scammers use automated dialers to randomly call hundreds of numbers, but the calls are disconnected after one ring. Victims see a missed call in their call log and, thinking it may be important, attempt to call the number back. The number appears as a typical U.S. 10-digit number, but in reality, these are international long-distance calls.
    • Do not answer any call from a number you don’t recognize, and don’t return the call, even if it looks like a legitimate number. If the missed call was truly important, the caller would have left you a message.
    • Block the number from making any more calls to you.
    • Report the number as spam via the www.reportarobocall.com portal as well as the FCC Consumer Complaint Center.
    • Download our exclusive Call Guardian® app. The free subscription will display a potential spam notice for all known offenders. The premium version displays enhanced details for all potentially risky callers and allows you to block calls by a selected risk level. You can download the app now in Android and iOS versions.
  • While there may not be a single answer that entirely ends these activities, we’re fully committed to fighting the increase of robocalls by taking the following measures:
    • The UScellular call-blocking solution aims to block as many of the calls made with malicious intent as possible. We automatically block these calls in the network and your phone won’t ring.
    • UScellular provides a free Call Guardian® app that displays “Potential Spam” on caller ID based on known offenders or displays “Spam Caller” on caller ID based on your personal spam list. You can download the app now in Android and iOS versions.
    • The premium version of our Call Guardian® app, for $3.99 per month, displays enhanced details for all potentially risky calls. Android users can block calls by a selected risk level of High, Medium or Low
    • UScellular uses STIR/SHAKEN technology to update our spam detection algorithm. STIR/SHAKEN is a caller ID authentication framework to help protect you against robocall scam campaigns to trick consumers into answering their phones.
    • UScellular supports the legislation, including the TRACED Act, which gives the FCC and enforcement agencies greater authority to pursue scammers.
    • Additionally, UScellular supports the Truth in Caller ID Act, which allows the government to charge robocallers with illegal “spoofing” once they prove the caller intended to defraud, cause harm or illegally obtain something of value.
  • The UScellular solution relies on data from our analytics partner, TNS. TNS analyses robocall data from more than one billion daily call events across hundreds of telecom providers. From this volume of data, TNS can extract insights on emerging robocaller tactics and trends. Learn about the latest robocalls scams here.
  • If you want to report a spammer, spoofer or scammer, please contact TNS via this website and use the Call Guardian® App to report the caller as spam.
    • Read the consumer tips from the Federal Communication Commission (FCC.gov) to stop unwanted robocalls.
    • Register your phone numbers on the Do Not Call List. Although this FTC registry won’t spare you from calls where scammers are intent on breaking the law, it should prevent you from receiving “live” telemarketing calls, which are regulated by the federal government, but are not illegal.
    • Don’t answer calls from numbers you don’t recognize. Legitimate callers will leave a voicemail.
    • Don’t call back numbers you don’t recognize. If you get a call from an unfamiliar number that rings once and hangs up, don’t call back.
    • Always confirm a charity’s identity (by calling or looking at its actual website) before donating.
    • If you think your personal information has been compromised, contact your local law enforcement.
    • Be diligent and don’t give out personal information over the phone.
