How do I find my number?

This SIM is data-only and therefore does not come with a phone number!

When should I install my eSIM?

You should wait until you land in your destination country before activating your eSIM - it will need to connect to a local network!

When does my eSIM plan start?

Your plan will only start when you land at your destination and connect to a network!

Is it possible to use an eSIM alongside a physical SIM?

Absolutely! If your phone is dual SIM compatible, you can use your eSIM and a physical SIM at the same time. This means you can use one for data and one for calls.

How do I check my balance?

You can check your balance by looking at your phone settings under data usage.


Settings > Mobile > Scroll to find Current Period Roaming


Settings > Connections > Data Usage > Billing Cycle and data warning > Select the period from the day you started using the SIM to the current day. Save and your data usage will be shown

How do I recharge?

As described on the website, the eSIM is non-rechargeable. The only way around this is to buy multiple eSIMs and swap them out as you go!

I'm having issues making phone calls or text messages

This SIM does not come with calls or texts as it's data-only! You can still receive phone calls or text messages though.

We'd highly recommend using data applications like FaceTime, Whatsapp, Facebook Messenger, Zoom or Google Meet to make calls and texts to Australia or USA. This will work using the data you have allocated to you.
Can I hotspot/tether from my phone?

Yep, you can hotspot/tether from your phone.

How do I know if my device is unlocked?

If you bought your device outright, it's most likely unlocked!

If you're unsure, the best way to find out is to call your Aussie network provider and ask! They'll be able to unlock it for you too. This might incur a fee! 🤔

Coverage: Where will this eSIM work?

  • Vietnam
  • Cambodia
  • Malaysia
  • Indonesia
  • Thailand
  • Singapore
If you're having connectivity issues in Singapore, try connecting manually to the "StarHub" network. 👇
Settings > Mobile > Network Selection > Disable automatic and change to another network and restart
Settings > Wireless & Networks > Mobile Networks > Network Operators > Search manually and change to another network and restart

You can still connect to networks that say "Forbidden Networks" - just press it a few times until it connects 📱

Troubleshooting :

My data isn't working...
  1. Check that you have Data Roaming & Mobile Data turned on in your Settings.
  2. Make sure that you have changed your APN settings to match the following:
    For iOS devices
    Name: internet
    APN: internet
    User name: [leave this section blank]
    Password: [leave this section blank]

    For Android devices
    Name: internet
    APN: internet
    Proxy: [leave this section blank]
    Port: [leave this section blank]
    User name: [leave this section blank]
    Password: [leave this section blank]
    MCC: 234
    MNC: 10
    Authentication type: PAP
    APN Protocal: IPV4
    APN Roaming Protocal: IPV4
  3. Restart your phone
If you've been using your eSIM but suddenly your data has stopped working

Sometimes the SIM can stop working. When this happens:

  1. Turn on Airplane Mode for 1 minute
  2. Turn off Airplane Mode - this should reboot the connection!
  3. If your phone says it's connected to LTE or 4G but the data isn't working, try to manually turn off LTE/4G to connect to 4G/3G.


Settings > Mobile > Mobile data options > Disable LTE > Restart


Settings > Connections > Mobile Networks > Network Mode > Switch to 3G/2G > Restart

It might look different depending on your device! If these instructions don't match exactly, explore your settings until you find Network Mode
