Best Flexible SIM and eSIM Options for Multiple Devices in Australia

Have a phone and a tablet? Maybe you keep a second phone for travel or use a smartwatch that needs its own connection. Once you have more than one device, choosing the right SIM setup can get a little confusing.

Should you use a physical SIM or eSIM? Can one SIM work across two devices? And what should you do if your phone or SIM goes missing?

The right option depends on how you use your devices.

A physical SIM (pSIM) is the removable card you put into a compatible device. An eSIM is built into the device and is activated digitally. Both connect your device to a mobile network, but they work differently when you move between devices.

If you need several devices connected at the same time, you may need separate services, Dual SIM, a data SIM or another option supported by your provider.

What Are Your Options for Using Multiple Devices?

There are several ways to keep more than one device connected.

You can move a physical SIM between compatible devices when you only need the service on one device at a time. Dual SIM lets you use two mobile services on one compatible phone. If another device needs its own connection, a separate mobile service or data SIM may make more sense.

An eSIM can make setup easier because there is no physical card to insert or keep track of. However, having an eSIM does not mean one mobile service can automatically be used on two devices at once.

The Australian Communications and Media Authority (ACMA) recommends checking coverage, costs, features and device compatibility before choosing a mobile service. It also recommends reading the provider's Critical Information Summary (CIS) before signing up.

Ways to Keep Multiple Devices Connected

1. Move a physical SIM between compatible devices

A physical SIM is useful if you sometimes switch between compatible devices.

For example, you could move your SIM from one phone to another when travelling or when your main phone is unavailable.

Advantages:

Easy to remove and move

Familiar and simple to use

No digital transfer is needed when moving the card

Limitations:

You have to physically move the SIM
The card can be lost or damaged
The other device must be compatible
Only one device can use the service at a time

A physical SIM may suit you if you prefer having something you can physically move between devices.

Before using a device with a new provider, check that it works with the provider's network.

2. Use Dual SIM on one phone

Dual SIM is useful when you want two mobile services on the same phone.

Depending on the device, this could be a physical SIM and eSIM combination or another supported setup.

You might use one number for personal calls and another for work, for example.

Dual SIM is not the same as using one SIM on two phones. It lets you have more than one mobile service available on one compatible phone.

Apple explains that Dual SIM features vary by iPhone model, region and carrier. Some supported iPhones can use two eSIMs, while other models use a physical SIM and eSIM combination.

3. Add a separate service for another device

If you want two devices connected at the same time, a separate service may be the simplest option.

Your phone can have its usual mobile service while your tablet has its own data service. There is no need to keep moving one SIM between the two.

If your provider supports it, multiple services can also be managed under the same account. With Yomojo, customers can manage multiple services through the Yomojo App or online dashboard.

4. Use your phone's hotspot

For occasional use, you may not need another service.

A phone hotspot lets you share your mobile data connection with a nearby tablet or another compatible device.

It is handy when you are travelling or away from Wi-Fi. Just keep in mind that hotspot use can affect your phone's data allowance and battery.

For regular use, a separate service may be more convenient.

What Should You Do If Your SIM Is Lost?

Losing a SIM is frustrating, but you do not necessarily need a new mobile number.

Contact your provider as soon as you realise the SIM is missing. They can help secure the service and explain how to get a replacement.

If you have a physical SIM

Ask your provider to suspend or secure the service if you think someone else could use the SIM.

Once the old SIM has been deactivated, you can request a replacement physical SIM or, if supported, move to an eSIM.

Don't keep using a lost SIM if you are concerned that someone may have access to it.

Yomojo customers can find replacement SIM information through the Yomojo Mobile Help Centre.

The Bottom Line

Choosing between a physical SIM and eSIM comes down to how you use your devices.

A physical SIM is handy if you want something you can move between compatible devices. An eSIM is convenient if you prefer digital activation and don't want to handle a physical card.

If several devices need to be connected at the same time, look beyond the SIM itself. Dual SIM, a separate mobile service, a data SIM or a phone hotspot may be a better fit depending on what you need.

And if your SIM or phone goes missing, act quickly. Secure the service, lock the device and contact your provider about a replacement.

The best setup isn't necessarily the newest one. It's the one that works with your device and fits the way you actually use it.
