Prevent Account Takeover. Before it happens.
SIM Swap is the most devastating of frauds, as your SIM is your identity, and once someone else controls it, they are effectively you. That 'I' in SIM stands for identity, after all. Emptying bank and crypto accounts and having access to everything you or your company owns and accesses is frightening and reputation-destroying.
Using the superpower of the SIM card and real-time mobile network operator data, not static databases, with XConnect's SIM Swap Check, you get the most up-to-date, accurate SIM swap check there is, teamed with reports that allow you to determine the right risk level for you.
We’re confident you cannot get a more effective SIM Swap solution.
What actually is a SIM Swap?
When someone convinces your Mobile Network Operator to transfer your phone number to a new SIM or eSIM. They gather information about you via phishing and/or social media or work profiles. They then convince your operator's customer support, in-person or online, that the new SIM card request from 'you' is legitimate, by providing that personal information about you. Fraudsters can also bribe phone shop insiders to carry out a SIM Swap for them.
Now, the fraudster controls a new SIM with your number attached to it, they now receive your calls, messages, SMS OTPs and can gain access to your identity via two-factor authentication codes. If your bank challenges a new access of your bank account, they will simply send an SMS OTP or call your number and be reassured by the fraudster. They can now take over your accounts, and by resetting passwords, access everything you own online. It’s a particular nasty form of identity theft which can have devastating financial and personal consequences.
Why do I need SIM Swap checks?
Or, more to the point, “What’s the business benefit or ROI?”.
SIM Swap isn’t the easiest crime to pull off: It entails a significant degree of risk for the fraudster who will try to convince a network operator that they are someone else.Some fraudsters will just bribe an employee to carry out a SIM Swap, which, again, requires investment, which they will want to recoup.
So, when a SIM Swap is performed, the fraudster will maximise their earning potential and try to empty all bank accounts, steal crypto, take over services, take out large loans in your name, etc. This harms banks whose reputations are damaged, enterprises that can lose millions or be put out of business, and increases reimbursement, chargebacks, and processing time for claims, not to mention causing customer worry and stress.
SIM Swaps devastate companies and their customers, and as network security gets tighter, criminals find other ways to take over accounts. XConnect's SIM Swap check prevents it before it happens - and let's CISOs sleep peacefully.
Fast
SIM Swap from XConnect delivers protection at network speed. Part of the SAFr platform, it detects SIM changes in real time – within milliseconds – giving banks, fintechs and enterprises instant insight to block fraud before it happens. Fast, accurate and seamless, it’s mobile identity intelligence direct from the network.
Flexible
There’s no such thing as a standard customer. That’s why SIM Swap from XConnect is built for flexibility. Our API fits straight into your risk decisioning flow, allowing you to ‘traffic light’ SIM activity in real time – block swaps within hours, flag recent changes for review, and fine-tune rules to match your exact risk appetite.
Unhackable
Since 1991, the humble SIM card has never been hacked or spoofed. It remains the most secure foundation of mobile identity — the ‘I’ in SIM stands for Identity, after all. SAFr Auth uses this trusted hardware as its anchor, making authentication truly unhackable and ensuring every user is verified at the source.
Inclusive
Inclusiveness by design. SIM Swap from XConnect delivers the same protection on every device – iOS, Android or even the most basic handset. No apps, no upgrades, no exclusions. It’s security that works for everyone, everywhere – another example of how XConnect is humanising identity for a truly connected world.
Invisible
SIM Swap from XConnect requires no user intervention and runs invisibly in the background, so genuine customers are never interrupted. Because checks happen at the network level, opportunities for fraudsters to bypass verification are greatly reduced. Zero intervention. Zero tolerance. Humanised checks.
Cryptography
The cryptographic key and algorithms within the SIM transform it into a secure hardware element, creating a powerful additional layer of protection against would-be fraudsters. Because authentication happens at the SIM level, it’s immune to common attacks targeting apps, SMS or devices – security that’s built in, not bolted on.
One API call
With the SAFr platform, simplicity is built in. Multiple fraud-prevention signals can be combined in a single API call – from number validity and reachability to SIM Swap status. One request gives you layered intelligence, so you can verify a number, assess risk and act instantly – without extra integrations or complexity.
Ultra secure
Complement SIM Swap through the SAFr platform with our unique secure flow and connection to operators providing additional services such as authentication to mitigate attack vectors like phishing and man-in-the-middle attacks. We believe we are the only Mobile Identity solution provider who offers this 360° total security.
Gen AI-proof
XConnect’s SIM Swap service is inherently immune to the growing threat of generative AI – a trillion-dollar fraud problem that’s undermining active authentication methods such as biometrics and voice recognition. Because the SIM cannot be faked or generated, it remains the most reliable defence against AI-driven identity attacks.
SIM Swap Case Study
UK Tier-1 Bank – SIM Swap Fraud Prevention
In March 2024, one UK Tier-1 bank used XConnect's SIM Swap Check to run 3.1 million checks in a single month.
87%of transactions passed, confirming no SIM Swap activity, while 1% (31,253) were flagged as SIM Swaps – over 1,000 potential frauds per day. Even if only 1% of those were genuine fraud attempts, given an average ATO fraud costing £3,000, the bank saved around £930,000 that month.
Half of detections were cross-network swaps, highlighting targeted fraud behaviour. 12% of checks were unknown due to MVNO or network limitations, which XConnect helps reduce using SAFr Auth and Device Swap Signals.
The result: cleaner data, lower fraud, and faster, safer transactions.
And a happy security team.
"The data returned to the company was extremely positively received and convinced the bank to use Mobile Identity SIM Swap checks to provide them with a strong and customisable approach to account takeover. They continue to use this today"
