SMS Notification Vs. Push Notifications

Which Is Better for Business?

Every day, businesses send thousands of messages to customers and employees. These include appointment reminders, delivery updates, promotions, and alerts. Two of the most common ways to deliver these messages are push notifications and SMS notifications.

Both land on a mobile device, but they work very differently. Understanding how each one works and when to use it can help your business communicate more effectively and reach more people. Here's what you need to know.

Comparing SMS vs Push Notifications

Reach

SMS can reach almost any mobile phone. Users don't need to download anything, create an account, or adjust any settings. Whether someone is using an Android SMS notification setup or a basic prepaid phone, the message gets through the same way.

Push notifications only reach users who have your app installed, have notifications turned on, and are connected to the internet. If someone deletes your app or disables notifications, you lose that channel entirely.

For the widest possible reach, SMS notifications perform better.

Open Rates and Visibility

Text messages get noticed. Most people read an SMS within minutes of receiving it, which makes it ideal for urgent updates, security alerts, and time-sensitive reminders.

Push notifications can drive engagement too, but many users mute or ignore them, especially if they feel bombarded. Some devices, like Samsung, give users granular control over notification sounds and behavior. On Samsung SMS notification settings, for example, users can customise alert tones, vibration patterns, and notification previews, which means your push notifications may never make a sound at all if a user has adjusted those settings.

Android SMS notification sound settings work similarly, giving users full control over how text alerts come through. This actually works in SMS's favor. Most users keep their default SMS alert active, meaning your message is more likely to be heard and seen.

Reliability

SMS runs on carrier networks, not the internet. As long as someone has a cellular signal, your message gets through.

Push notifications depend on internet connectivity, app performance, device settings, and notification permissions. There are simply more things that can go wrong, and no way to know if a message was silenced before it was seen.

This is why businesses rely on SMS when a message absolutely needs to be delivered.

Cost

Push notifications are generally cheaper to send since they go through app systems rather than telecom networks. SMS messages typically come with a per-message cost, which adds up at scale or for international sending.

That said, many businesses still choose SMS for critical communication because the reliability and visibility are worth the investment. The right SMS notification service can also help manage costs through smart automation, bulk sending, and delivery reporting.

Compliance

SMS messaging in Australia is regulated under the Spam Act 2003 and ACMA guidelines. Businesses must obtain consent, clearly identify the sender, and include a simple unsubscribe option in all marketing SMS. Notifyre can help automate opt-out management and support compliant SMS communication.

Push notifications fall under the Privacy Act 1988 and Australian Privacy Principles, alongside Apple and Google platform requirements. Businesses must obtain explicit consent, communicate the purpose and frequency of notifications, and provide a clear opt-out through device settings or in-app preferences. 

The Verdict: When to Push, When to Text

Push notifications are great for app engagement and keeping users active inside your platform. But they come with conditions. The right app, the right settings, the right internet connection.

SMS doesn't have those conditions. It works on virtually any phone, anywhere, without needing an app or a Wi-Fi signal. Whether your customers are using the latest Android SMS notification setup or an older device, a well-designed SMS notification system reaches them reliably and consistently.

For businesses that can't afford to miss a delivery, SMS remains the most dependable channel available. Paired with a platform like Notifyre, it's also one of the most powerful.
