Supriti Updated by Supriti

First things first...

  1. Make sure that you're in one of the 44 countries where the SIM works! 🌎
  2. Make sure you have Data Roaming turned on and you've restarted your phone.

How do I activate?

  1. We will activate your SIM card on the date that you provide during checkout.
  2. Once you arrive at your destination country, insert the SIM into your device.
  3. Turn on Data Roaming in your settings
  4. Restart your device
  5. You'll receive a text letting you know your credit has been applied.
  6. After your SIM is connected, you'll receive another text letting you know that your SIM is activated and your 30 days will begin.

Easy peasy! 🙌

It's important to note; we activate your SIM card at 2pm AEDT (4am GMT) on the date you provided during checkout.

Once we activate it, the network will continually check to connect your SIM to the network.

This connection can take anywhere from a few minutes to a few hours. If your SIM has not connected in a few hours, please contact us with your phone number via email at or We will be able to check whether your SIM is active.

I've just put my SIM in my phone and it says "No Service"

If you've inserted the SIM into your phone and you didn't get a 'Welcome' text message or it says 'No Service', it's possible that it hasn't been activated yet. Our system automatically activates these SIMs at 2pm Sydney time on the nominated date - simply message us to let us know that you need an earlier activation and we can help you out :)

You can also try to manually select a network through your settings.


Settings > Mobile > Network Selection > Disable Automatic > Wait for networks to pop up and select one


Settings > Connections > Mobile Networks > Network Operators > Search networks manually > Wait for networks to pop up and select one

If it doesn't connect, you might need to click on one a couple of times and then restart your phone.

Note: May differ depending on your device - If these instructions don't match, explore your settings until your find Network Selection or Network Operators

Which one do I choose?

Try any of them, and if it doesn't work, try another one!

It's still not working...

Try the SIM in another phone if you can, and see if it'll activate.

My SIM was working great but suddenly it says "No Service"

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!

My device says "No SIM"

  1. Take the SIM out and put it back into your phone and restart
  2. Try the SIM in another phone
  3. If it's saying No SIM in 2 different phones, then contact us!

I've tried everything and it's still not working

Sometimes even if you do everything right, the SIM still doesn't work! SIM cards and mobile phones are technical products so it's impossible for everything to work perfectly all the time. 🤷🏽‍♀️

If you still need help, the best step is to contact O2 directly via their phone number: +44 7860 980 202

O2 Opening times

  3. Restart your phone
  4. If it's still not working, try the SIM on another phone to see if it'll work there.

I'm overseas and I've run out of data, how do I top-up?

This SIM is 'non-rechargeable' because the only ways to top-up are:

  • By physically going into an O2 store in the UK
  • Online with a UK credit card and address

If you have access to these methods, then you can top-up!

If you don't and you need to access more data, we recommend you grab a SIM locally 😊

I keep getting messages telling me to top-up

If your data is working, just ignore the messages telling you to top up!

Also, make sure you check your balance by calling 4444 to see your expiry and data balance! 🙃

Can I call USA or Australia with this SIM?

Unfortunately, this SIM doesn't come with calls/texts to USA or Australian numbers!

We'd highly recommend using data applications like FaceTime, Whatsapp, Facebook Messenger, iMessages, Viber or Skype to make calls and texts instead. This'll use the 100GB of data you have allocated to you.

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 call and texts to Australia or USA. This will work using the 100GB of data you have allocated to you.

Can I hotspot/tether from my phone?

Yep, you can hotspot/tether from your phone.
