Alerts customers actually trust.
The whole point of a fraud alert is that the customer believes it. Send transaction alerts and 2FA codes from your verified brand, name, logo, checkmark, so customers know it’s really you, and verify or freeze in one tap. Branded over RCS, delivered everywhere with automatic SMS fallback.

Fraud alertThe real fraud problem is the alert itself.
Customers have been trained to distrust security texts, because scammers send fake ones constantly. A plain SMS that says “Suspicious charge, reply YES or call this number” looks identical whether it’s from a real bank or a phishing ring spoofing one. So real alerts get ignored and fake ones get clicked. The fix is proof of identity: a SimplyRCS alert arrives from your verified brand, a registered sender with your name, logo, and a checkmark the customer can see, so a legitimate alert is visibly different from a spoofed one.
What a fraud alert should look like.
A trustworthy alert proves who it’s from, states exactly what happened, and gives a safe one-tap response, without ever asking the customer to call an unknown number or click a suspicious link. Verification is the whole job.
Branded passcodes beat anonymous ones.
The same trust problem hits two-factor codes. A passcode from an unknown short code is indistinguishable from a phishing attempt harvesting your login. A SimplyRCS one-time passcode arrives from your verified brand, so customers know the code is legitimately yours, and over RCS it can include a one-tap “this wasn’t me” path to flag an unexpected login instantly.
- Branded OTP: codes arrive from your verified sender, not an anonymous number
- One-tap auto-fill (where supported): reduce friction at login
- "It wasn’t me" action: let customers flag a suspicious login attempt in one tap
- Guaranteed delivery: falls back to SMS so codes always arrive in time
2FA passcodeVerified alerts in five steps.
We register your verified RCS sender and handle carrier vetting, so alerts carry your name, logo, and checkmark: the foundation of the whole use case. Compliance and identity are handled by our team.
When the whole job is trust, verification wins.
For most use cases, RCS is a better experience. For fraud alerts and 2FA, it’s a better defense. Plain SMS can’t prove who sent it, which is precisely why phishing works. A verified sender is visibly, structurally distinct from a spoof.

Fraud alert & 2FA questions.
How do banks send fraud alerts by text?
Banks send fraud alerts by texting customers when a suspicious transaction is detected, asking them to verify or decline it. With SimplyRCS, those alerts go out from a verified, branded sender: name, logo, and checkmark, and let customers verify the charge or freeze the card in one tap, with automatic SMS fallback so the alert always arrives.
Are SMS fraud alerts and 2FA codes secure?
Plain SMS alerts and codes are functional but cannot prove who sent them, which is why phishing attacks imitate them so effectively. RCS improves this by sending from a verified, registered brand the customer can visibly distinguish from a spoof. SimplyRCS uses verified RCS where supported and falls back to SMS, pairing trust with guaranteed delivery.
How does RCS help stop SMS phishing?
RCS messages come from a verified, registered sender with your brand name, logo, and a checkmark: signals a scammer using a spoofed SMS number cannot easily replicate. This lets customers tell a legitimate alert from a phishing attempt at a glance, so real alerts get trusted and fake ones get ignored.
What should a fraud alert text say?
A trustworthy fraud alert proves who it is from (verified branding), states the specifics (amount, last four digits, merchant, time), and offers a safe one-tap response, verify or freeze, without asking the customer to call an unknown number or click a link. For example: "We blocked a $487 charge on your card ending in 4421. Was this you? [Yes] [No, freeze card]."
Can customers verify or freeze a card from the text?
Yes. Over RCS, SimplyRCS alerts include tappable buttons: confirming the charge clears the flag, and freezing triggers your card-control action and routes the customer to a specialist in the Inbox. On non-RCS devices, the alert falls back to SMS with a reply-to-respond instruction.
Can I send branded 2FA or one-time passcodes?
Yes. SimplyRCS sends one-time passcodes from your verified brand instead of an anonymous short code, so customers know the code is legitimately yours. Over RCS, codes can include a one-tap "it wasn’t me" action to flag suspicious logins, and they fall back to SMS to guarantee timely delivery.
Do fraud alerts work on iPhone and Android?
Yes. Verified RCS alerts reach iPhones (iOS 18.1+) and Androids (Google Messages). Because security messages must always arrive, SimplyRCS falls back to SMS automatically on any device that cannot receive RCS, so codes and alerts are never delayed.
Is sending fraud alerts and 2FA compliant?
Transactional security messages like fraud alerts and 2FA can be sent with appropriate consent and content practices. SimplyRCS provides verified senders, audit logging of every send and response, and per-channel consent tracking. Regulated businesses should review the trust center and the financial-services industry page for specifics.
