Message and Data Rates May Apply: What It Means and Why It Matters for SMS Communication

Message and Data Rates May Apply: What It Means and Why It Matters 

If you’ve ever signed up for a text alert from a business, entered an online sweepstakes, or received a promo SMS from a company, you’ve probably read the following disclaimer: “Message and data rates may apply.” You’ll see it at the bottom of opt-in forms, in welcome texts and throughout SMS marketing campaigns the world over.

But what does that actually mean? More importantly, what does this mean for businesses running SMS communication programs?

This guide covers everything – what the disclaimer is about, why compliance demands it, and how platforms like MessageBlink enable businesses to communicate transparently with their audiences.

What Does “Message and Data Rates May Apply” Mean?

“Message and data rates may apply” (sometimes shortened to “msg and data rates may apply”) is a standard disclaimer used to inform recipients that their mobile carrier may charge them for sending or receiving text messages.

Charges will depend on the recipient’s individual mobile plan. If you do not have unlimited SMS or data, your carrier may charge you for the following:

— Sending and receiving SMS (standard text) messages — Accessing links or content within a message using your mobile data — Anything that uses their carrier’s messaging or data services in excess of their plan’s monthly allowance

That disclaimer does not mean the business sending the message is charging the recipient. It’s a notice that the carrier may charge fees, which is nothing the sender has any control over.

The business sends the message, but the carrier decides if the recipient pays to receive it.

Why We Have This Disclaimer

The “message and data rates may apply” disclaimer is primarily for consumer protection and transparency in commercial messaging.

Regulatory agencies such as the Federal Communications Commission (FCC) and trade associations such as the Cellular Telecommunications Industry Association (CTIA) have established standards requiring that companies disclose this information before or at the time a consumer enrolls in any SMS program.

One of the most important laws governing business text messaging in the U.S. is the Telephone Consumer Protection Act (TCPA). It requires businesses to have clear and honest communication with contacts. Not making the necessary disclosures, including this disclaimer, can lead to regulatory enforcement and class action lawsuits against businesses.

The disclaimer also builds consumer trust beyond the legal requirements. This shows that a brand is transparent about what it takes to be part of their messaging program.

Message and Data Rates: A Consumer Guide

This disclaimer is important to know so recipients don’t get billing surprises. Here’s when you’re most likely to be charged by a carrier:

Limited Texting Plans

If you’re on an older or budget mobile plan, you might have a fixed number of SMS that you can send per month. Once the limit is reached, any message beyond that, including messages received from businesses, could be subject to a per-message charge.

Data-Driven Engagements

Clicking on an SMS message link uses mobile data. If the user is on a capped data plan, and not on Wi-Fi, that interaction will draw from their data allotment and could result in overage charges.

Roaming Scenarios

International travelers on a consumer plan may be charged higher rates for receiving text messages, depending on their carrier’s roaming policies.

What Consumers Can Do

Check your SMS and data allowances by going to your current mobile plan. For questions regarding charges for text message billing, contact your carrier. Carrier-side fees are typically invisible and out of the control of the businesses sending you text messages.

Message and Data Rates May Apply: What This Means for Businesses

For businesses that use SMS as a communication channel, this disclaimer is not just an option – it’s a compliance requirement and an ethical obligation.

Where to Put the Disclaimer

The following locations should include the “message and data rates may apply” notice:

— On opt-in forms and landing pages where people opt-in to receive text messages — In your first confirmation or welcome message sent after a user opts in — In any terms and conditions related to your SMS program — In keyword response messages (for example, when a user texts a word to join a list)

How to Show It Correctly

The regulatory guidance and CTIA best practices are clear — the disclaimer must be conspicuous, legible and not hidden. What businesses should not do:

— Show it in a very small font — Use text colors that blend into the background — Hide it behind multiple layers of navigation — Put it in a location where a reasonable user would not encounter it

The rule is: transparency. If a consumer later states they did not know they could be charged because the disclaimer was not properly displayed, that is a liability risk to the business.

Complete Required SMS Opt-In Disclosure Language

Generally, a compliant SMS opt-in flow should include all of the following elements in a business’s disclosure language:

1. Name of Program or Business
2. Description of type of messages to be received
3. Frequency of Messages (Estimated) (e.g. “up to 4 messages a month”)
4. Message and data rates may apply
5. How to unsubscribe (usually “Reply STOP to unsubscribe”)
6. Instructions for getting help (usually “Reply HELP for help”)
7. Terms and Privacy Policy link

Sample compliant opt-in language:

“By subscribing you agree to receive SMS messages from [Brand Name] regarding [message type]. Message frequency can vary. Message and data rates may apply. Reply STOP to cancel. Reply HELP for assistance. See our Privacy Policy at [URL].”

Best Practices for Businesses: Where to Place the Disclaimer

Here are the non-negotiable best practices every business SMS program should follow to summarize the compliance and ethical standards around this disclosure:

— Include the disclaimer at every opt-in touchpoint before or at the time of obtaining consent — Write the disclosure in clear, readable language at an appropriate font size— Include opt-out instructions (STOP) and help instructions (HELP) in the same disclosure block—state message frequency clearly so users know what to expect. Review and update your opt-in language whenever your messaging program substantively changes— Maintain records of when and how consent was collected for each subscriber — Work with an SMS platform that supports compliant workflow design out of the box

“Message and data rates may apply” are four words that mean a lot in the world of business text messaging. It’s a warning for consumers to check their mobile plan.
