Understanding 5G-SA (Standalone) on Xperia Smartphones

IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

5G-SA, or 5G Standalone, is a next-generation 5G network mode that uses a full 5G core without relying on a 4G connection. This article explains what 5G-SA is, how it works, why it matters, and what Xperia users should know.

What is 5G-SA?

5G-SA is a 5G network that runs entirely on 5G technology. The radio network is 5G, and the core network is also 5G.

No 4G infrastructure is required. This enables lower latency, higher reliability, and new 5G-only features.

How is 5G-SA different from 5G-NSA?

5G-NSA (Non-Standalone) uses a 5G radio but depends on a 4G core for signalling. 5G-SA removes this dependency. This change improves performance and unlocks advanced network capabilities.

Why does 5G-SA matter?

5G-SA provides the performance that the 5G standard was designed to deliver. Xperia users may see the following benefits:

• Lower latency – improves cloud gaming, video calls, and real-time apps.
• Better indoor reach – some operators use low-band 5G-SA frequencies.
• More stable connections – traffic is handled by a dedicated 5G core.
• Future-ready features – supports VoNR (Voice over New Radio), advanced IoT (Internet of Things), and network slicing.

Which Xperia models support 5G-SA?

Support depends on the Xperia model, region, mobile operator, and software version. Some models support 5G-SA now. Others may gain support through future updates. Operator certification is also required before 5G-SA can be enabled.

For the latest information, check your Xperia specifications, update notes, or your operator’s 5G-SA support list.

Do I need a new SIM card?

Many SIM cards already support 5G. Some operators may require a 5G-ready SIM or a plan that includes 5G-SA. Contact your operator if you are unsure.

How do I enable 5G-SA?

When both your Xperia device and your operator support 5G-SA, the phone will usually connect automatically. You can verify your settings by checking:

1. Open Settings
2. Tap Network & Internet
3. Select SIMs
4. Choose your active SIM
5. Open Preferred network type
6. Ensure 5G is enabled

Why isn’t 5G-SA available everywhere?

5G-SA rollout is ongoing. Operators often launch 5G-SA in specific regions or for specific devices first. You may not see 5G-SA if your operator has not enabled it, your device is not yet certified, a software update is pending, or your subscription does not include 5G-SA.

Does 5G-SA improve Voice Calls?

Yes, when VoNR (Voice over New Radio) is available. VoNR can reduce call setup time and improve voice quality. Availability depends on your operator and Xperia model.

What is VoNR?

VoNR (Voice over New Radio) is a technology that allows a smartphone to make voice calls directly over a 5G network, without falling back to 4G or 3G.

It uses the 5G NR (New Radio) network for both voice and data at the same time.

How does 5G-SA affect battery life?

Battery usage varies by operator implementation and coverage. In some networks, 5G-SA can be more efficient than 5G-NSA. Sony continues to refine device performance through software updates.

Do I need 5G-SA to use 5G?

No. 5G-NSA remains widely available and provides strong 5G performance. 5G-SA is an enhancement that offers additional benefits and future capabilities.

Summary

5G-SA is a fully standalone 5G network that delivers lower latency, better reliability, and support for new 5G services. Availability depends on your Xperia model, region, software version, and mobile operator. Your device will connect automatically when 5G-SA is supported.
