A devastating series of cyberattacks has left an Ohio resident questioning whether to abandon the phone number she’s used for two decades. Lela experienced repeated account breaches affecting her checking accounts, credit cards, and even newly issued cards that criminals charged before she received them. Despite switching carriers to AT&T and implementing multiple security measures, hackers continued accessing her accounts through her phone number.
The pattern of attacks raised a critical question many victims face: is changing to a completely new phone number the only way to stop the cycle? Security experts warn this decision requires careful timing and preparation, as rushing to change numbers can create additional vulnerabilities rather than solve existing ones.
How phone numbers became prime targets for criminals
Modern phone numbers serve as far more than simple contact information. They function as master keys to digital identity, linked to bank accounts, credit cards, email services, Apple ID, Google accounts, medical portals, shopping platforms, and password reset systems. This extensive integration makes them extraordinarily valuable to cybercriminals seeking to exploit multiple accounts simultaneously.
When criminals gain control of a phone number, they receive all calls and text messages directed to it, including security codes meant exclusively for the legitimate owner. This access enables them to reset passwords, infiltrate email accounts, drain financial resources, and maintain persistent access even after victims believe they’ve resolved the security breach.
Understanding SIM swap and port-out scams
Two primary attack methods allow criminals to hijack phone numbers. SIM swap scams occur when attackers deceive mobile carriers into transferring a victim’s phone number to a SIM card or eSIM under the criminal’s control. Port-out scams involve moving the number to an entirely different carrier without authorization.
Victims typically first notice these attacks when their phone suddenly loses service. Meanwhile, the scammer begins receiving all incoming calls and texts, gaining immediate access to verification codes for email, banking, credit cards, and other critical accounts. Many victims remain unaware of the breach until money disappears from accounts or services become locked.
When changing phone numbers makes sense
Abandoning a long-held phone number should rarely serve as the first defensive move. Changing numbers prematurely can trigger loss of access to accounts still configured with the old number for recovery purposes. Even more dangerous, if criminals retain control of the abandoned number, they may continue receiving password reset codes for accounts still tied to it.
However, certain circumstances warrant considering a new number. These situations include:
- Repeated targeting despite carrier-implemented protections and security measures
- Continued use by hackers for resetting account passwords
- Carrier confirmation of unauthorized SIM swaps or port-out attempts
- Extensive compromise of multiple accounts linked to that number
- Wide exposure of the number on dark web forums or data broker websites
Before making this transition, victims must first secure their current number and systematically update all critical accounts. Otherwise, the old vulnerabilities simply transfer to the new number.
Essential carrier security measures to implement immediately
Contacting the mobile carrier directly represents the crucial first step in stopping ongoing attacks. Victims should use only official phone numbers from the carrier’s website or billing statements, avoiding contact information from texts, emails, or voicemails that could be fraudulent.
When speaking with carrier representatives, request a comprehensive check for SIM swap attempts, port-out requests, unauthorized account modifications, unrecognized devices, call forwarding settings, number transfer activity, and unknown authorized users on the account. Then insist on implementing stronger protective measures including a robust account PIN, port-out freeze or number transfer lock, SIM lock where available, and enhanced account verification requirements. Remove any unknown authorized users discovered during the review.
Securing email accounts before resetting passwords
Email accounts often serve as the master control point for entire digital lives. When hackers control email access, they can reset passwords for banks, credit cards, shopping accounts, and social media platforms. Before changing any other passwords, victims must ensure their primary email account is completely clean and secure.
This process requires changing the email password from a verified safe device, signing out of all active sessions, checking recovery email addresses, reviewing recovery phone numbers, removing unknown forwarding rules, examining connected apps and devices, and enabling stronger two-factor authentication methods. If email access remains compromised, hackers can systematically undo every recovery step victims attempt.
Moving beyond text message authentication
Text message security codes provide better protection than no authentication, but become dangerously unreliable when criminals specifically target phone numbers. For important accounts, security experts recommend switching to authenticator apps, physical security keys, or passkeys where supported.
This upgrade matters most for email services, banking platforms, credit cards, Apple ID, Google accounts, social media, password managers, tax accounts, and government services. These enhanced authentication methods make accounts substantially harder to breach even if criminals successfully gain control of the phone number.
Treating compromised cards as identity theft
When criminals charge new credit cards before victims receive them, the situation extends beyond simple account hacking into potential identity theft or complete account takeover. Victims should contact each bank and credit card company directly, specifically requesting the fraud department and explaining that accounts, phone numbers, or identity may be compromised.
Request immediate cancellation of compromised cards, issuance of replacement cards with new numbers, placement of fraud alerts on all accounts, and review of recent transactions for unauthorized charges. Financial institutions possess specialized fraud teams trained to handle these complex situations and can implement additional monitoring and protective measures.
