In the age of WhatsApp, Truecaller Messaging, Google RCS, Facebook Messenger, and a myriad of other messaging apps, one might wonder if Short Message Service (SMS) still holds any relevance in 2024. With newer, richer communication channels emerging, SMS—a technology that has been around since the early 1990s—seems almost antiquated. However, its longevity is no accident. SMS continues to be a powerful tool in customer communication, particularly within the Communications Platform as a Service (CPaaS) industry.
The Enduring Power of SMS
Despite the proliferation of messaging apps, SMS remains a cornerstone of communication strategies for businesses worldwide. According to SlickText, 5.9 billion people globally are expected to send and receive SMS messages by the end of 2025. This is largely due to its ubiquity and simplicity; SMS is supported by virtually every mobile device, without the need for an internet connection or additional app downloads.
- Universal Reach: SMS has unparalleled reach, capable of connecting with anyone who owns a mobile phone. Unlike over-the-top (OTT) messaging apps like WhatsApp, Google RCS Busienss Messaging (RBM), Truecaller Messaging, or Messenger, which require internet access and a smartphone, SMS works on any mobile phone—smart or feature—and in areas with limited or no internet connectivity. This makes SMS particularly valuable in regions with low smartphone penetration or unreliable internet infrastructure.
- High Open and Response Rates: One of the biggest strengths of SMS is its immediacy. Studies have consistently shown that SMS messages boast an open rate of 98%, with 90% of them being read within three minutes of delivery. In contrast, email open rates hover around 20-30%. Additionally, the response rate for SMS is significantly higher than other channels, making it an effective medium for time-sensitive communications, such as appointment reminders, security alerts, and promotional offers.
- Simplicity and Familiarity: SMS’s simplicity is a double-edged sword; while it lacks the rich media capabilities of newer messaging platforms, this very simplicity makes it accessible and easy to use for everyone. There are no learning curves, no apps to install, and no updates to manage—just plain text communication. This familiarity is comforting for users across all demographics, especially older adults who may not be as tech-savvy.
SMS in the CPaaS Industry
The CPaaS industry, which provides businesses with the tools and APIs needed to integrate communication services like SMS, voice, and video into their applications, continues to see SMS as a vital component of its offerings. In fact, SMS often serves as the backbone for many CPaaS solutions, particularly in areas like two-factor authentication (2FA), customer notifications, and transactional messaging.
- Two-Factor Authentication (2FA): SMS remains the most widely used method for 2FA, providing an additional layer of security for online accounts. A 2023 report by MarketsandMarkets projected that the global 2FA market would grow from $4.5 billion in 2020 to $8.1 billion by 2025, with SMS-based authentication playing a significant role. Despite the rise of alternative methods like push notifications and biometric authentication, SMS’s simplicity and ubiquity make it a go-to option for businesses looking to enhance security with minimal friction.
- Transactional Messaging: Businesses rely heavily on SMS for sending transactional messages—order confirmations, shipping updates, and appointment reminders. These messages are crucial for maintaining customer trust and ensuring smooth operations. According to a 2023 study by Juniper Research, global businesses sent over 2.7 trillion SMS messages in 2022, with transactional messages accounting for a significant portion of this volume. The report also highlighted that SMS-based transactional messaging is expected to grow by 20% annually through 2024, driven by the increasing adoption of mobile commerce and the demand for real-time communication.
- Customer Notifications and Alerts: Whether it’s sending a flight delay notification, a bank transaction alert, or an appointment reminder, SMS is often the preferred channel for delivering critical information. Its reliability and immediate delivery make it ideal for time-sensitive alerts. A 2021 survey by Forrester found that 70% of businesses cited SMS as the most effective channel for delivering urgent notifications to customers, outpacing email and push notifications.
The Evolution of SMS
While SMS has proven its staying power, it is not without limitations. Recognizing the need for modernization, the industry has introduced Rich Communication Services (RCS), often referred to as “SMS 2.0.” RCS enhances the traditional SMS experience by enabling features such as read receipts, typing indicators, and the ability to send multimedia content like images, videos, and files. In essence, RCS brings many of the functionalities of OTT messaging apps to the native messaging app on your phone, without the need for third-party applications.
- Adoption and Reach: While RCS has seen slower adoption compared to its OTT counterparts, its potential is significant. As of 2024, over 1 billion people globally had access to RCS messaging, and the number is expected to grow as more mobile carriers and device manufacturers support the protocol. Google has been a major proponent of RCS, integrating it into its Android Messages app and pushing for broader carrier support worldwide. According to a 2023 report by the GSMA, 90% of mobile operators worldwide are expected to support RCS by 2025.
- Business Messaging with RCS: RCS offers a richer, more interactive experience for business messaging. Companies can use RCS to send branded messages that include images, videos, and even action buttons, allowing customers to make purchases, book appointments, or track deliveries directly within the messaging app. A 2023 survey by Mobilesquared found that businesses using RCS for customer communication saw a 30% increase in engagement compared to traditional SMS. The same report predicted that RCS-based messaging would generate $74 billion in revenue by 2025, as businesses increasingly adopt the technology to enhance their communication strategies.
- Challenges and Competition: Despite its promise, RCS faces several challenges. For one, its adoption has been uneven, with some carriers and regions lagging. Additionally, RCS must compete with established OTT messaging platforms like WhatsApp and iMessage, which already offer rich media capabilities and have large user bases. To overcome these challenges, industry stakeholders must work together to ensure widespread support and interoperability across networks and devices.
SMS and Omnichannel Communication Strategies
In 2024, businesses are increasingly adopting omnichannel communication strategies to provide a seamless and consistent experience across all customer touchpoints. SMS plays a critical role in these strategies, acting as a bridge between different communication channels.
- SMS as a Fallback Channel: One of the key advantages of SMS in an omnichannel strategy is its reliability. When other channels fail—due to poor internet connectivity, app crashes, or other issues—SMS serves as a dependable fallback. For example, if a customer does not receive a push notification due to a network issue, an SMS can be sent as a backup to ensure the message is delivered. This redundancy is particularly important in critical communications, such as emergency alerts or time-sensitive promotions.
- Integrated Customer Journeys: SMS can be seamlessly integrated into broader customer journeys, complementing other channels like email, social media, and voice. For instance, a customer might receive an SMS notification about an upcoming sale, which is followed by a personalized email with product recommendations. Later, they might receive a push notification reminding them of the sale’s end, all of which are part of a coordinated strategy to guide the customer through the purchase journey. A 2023 report by Adobe found that businesses using integrated omnichannel strategies, including SMS, saw a 10% increase in customer retention rates and a 15% boost in customer lifetime value.
- Personalization and Contextual Messaging: With advances in AI and data analytics, businesses can use SMS to deliver highly personalized and contextually relevant messages. For example, a retailer could send an SMS with a personalized discount code based on the customer’s past purchase behavior and location. According to a 2023 study by Salesforce, personalized SMS campaigns have a 29% higher conversion rate than non-personalized campaigns. As AI and machine learning technologies continue to evolve, the ability to deliver personalized SMS messages in real-time will only improve, making SMS an even more powerful tool in the marketer’s arsenal.

In 2024, Uber expanded its use of SMS to include real-time updates on ride details and driver incentives. For example, drivers now receive SMS notifications about surge pricing areas, upcoming bonuses, and changes in route due to traffic conditions. This proactive communication has led to a 30% increase in driver engagement and a 25% boost in on-time arrivals for pickups. Additionally, the integration of SMS with Uber's driver app has improved overall driver satisfaction by providing clearer and more immediate information.

In 2024, Starbucks implemented an SMS-based system where customers receive personalized offers based on their purchase history and preferences. For example, a customer who frequently orders coffee may receive an SMS with a special discount on their next coffee purchase. This personalized approach has increased engagement with the loyalty program by 40% and boosted repeat purchases by 20%. The SMS system has also helped Starbucks maintain a strong connection with its customers, reinforcing brand loyalty and driving sales.
- CVS Health’s SMS Medication Reminders: CVS Health has leveraged SMS to provide medication reminders and health tips to its customers. In 2024, CVS enhanced its SMS service to include personalized medication schedules and health advice based on the customer’s prescription history and health conditions. For instance, a customer who has a chronic condition may receive timely reminders to refill their medication and educational tips on managing their condition. This initiative has improved medication adherence by 15% and reduced missed doses by 10%. The SMS reminders have also contributed to better health outcomes for CVS customers and have helped the company build stronger relationships with its clientele.
SMS continues to dominate in 2024 due to its unique advantages in reach, immediacy, and adaptability within modern communication ecosystems. Businesses leveraging SMS report significant improvements in customer engagement, with personalized SMS campaigns yielding 29% higher conversion rates compared to non-personalized efforts. The rise of omnichannel strategies has also cemented SMS’s role as a reliable fallback, providing consistent communication across multiple touchpoints.
Transactional SMS usage, a key driver of business operations, is expected to grow at a rate of 20% annually, reflecting the increasing reliance on real-time communication. Moreover, the global market for SMS in sectors like two-factor authentication, projected to exceed $8.1 billion by 2025, underlines its continued value in enhancing security. The evolution of Rich Communication Services (RCS) adds another dimension to SMS’s future, with early adopters already witnessing a 30% boost in customer engagement. This evolution, combined with the enduring simplicity and trustworthiness of SMS, ensures its lasting significance in business communication strategies, well into the coming years.
