eSIM (embedded SIM) technology allows you to connect to mobile networks without using a physical SIM card. As 5G becomes more widespread, many people wonder if their eSIM can access this faster network. Understanding how 5G works with eSIM is important for those using mobile data abroad. If you are using an eSIM, 5G compatibility depends on several factors, including your phone, carrier, and region. According to the GSMA Intelligence report, 5G networks provide significantly higher speeds and lower latency compared to previous generations, but actual performance varies depending on local infrastructure [1].

Does eSIM support 5G?

Yes, most eSIMs support 5G if the device, plan, and network are compatible. An eSIM is not limited to a specific network type. Just like physical SIM cards, eSIMs can connect to 3G, 4G, and up to 5G networks, as long as your phone, mobile carrier, and data plan support it. The ability to access 5G depends on the entire ecosystem. It is not determined by the SIM technology alone.

Which phones support 5G with eSIM?

Many modern smartphones that support eSIM also offer 5G connectivity, especially newer models from popular brands. Devices such as the iPhone 12 and newer, Samsung Galaxy S21 series and above, Google Pixel 5 and later models, as well as selected Xiaomi and Oppo phones, are known to support both eSIM and 5G.

Disclaimer: However, support can vary by device and region. Always check your phone’s specifications to confirm that both eSIM and 5G are enabled.

How can I check if my eSIM supports 5G?

It depends on your phone, mobile carrier, eSIM service, and data plan. A travel eSIM does not limit which network types you can connect to. However, to use 5G, your phone must support both eSIM and 5G technology, your plan must include 5G service, and your carrier must offer 5G in your destination. You can check this in your device settings or by contacting your carrier or eSIM provider.

How do I activate 5G on my eSIM?

You usually don’t need manual setup, but your device settings must be correctly configured. If your phone supports both eSIM and 5G, and your mobile plan includes access to this next-generation network speeds, your device will typically connect automatically. This is possible as long as your carrier provides coverage in your location. Still, it's important to check your settings to ensure everything is properly enabled:

On iPhone

1. Go to Settings > Cellular > Cellular Data Options > Voice & Data.

2. Select 5G Auto (recommended) or 5G On.

3. Under Data Mode, choose Allow More Data on 5G for enhanced quality when supported [2].

On Android

1. Open Settings > Connections (or Network & Internet) > Mobile Networks > Preferred Network Type.

2. Choose an option that includes 5G (e.g., 5G/LTE/3G/2G).

3. In dual SIM or eSIM-enabled phones, ensure the correct SIM profile is active under SIM Manager or Mobile Network.

Note: With many global eSIM providers, such as Roamless, 5G is available in supported areas where local carriers offer 5G coverage. Availability may still vary depending on your location and the carrier’s infrastructure.

What are the benefits of using 5G with an eSIM?

5G offers several key advantages over 4G, particularly for people who rely on mobile data during international travel. Here are some of the main advantages:

• 5G offers faster download and upload speeds than 4G.

• High-resolution streaming and video calls become more stable and consistent.

• Online games and interactive apps perform better.

• Better network efficiency in crowded areas, such as airports or public events.

Note: An international research on eSIM and 5G integration notes that 5G-enabled eSIMs significantly improve performance in tasks that require immediate response, such as cloud gaming and VoIP based communication apps, by reducing packet delays and increasing bandwidth [3].

Does Roamless eSIM support 5G?

Yes, Roamless offers 5G access in supported countries and regions, depending on local network infrastructure. Most RoamlessFix (prepaid plans with fixed durations) and RoamlessFlex options (a ''pay as you go'' model with no expiration) support up to 5G speeds.

• Roamless eSIM is compatible with many modern mobile devices and network types.

• No speed throttling applies, even on 5G-capable plans.

• Hotspot and tethering are fully supported and available without limits.

• Activation is fast and simple, with options including QR code, manual entry, and one-tap setup on iOS 17.4+ devices.
