Learn how to set up your SIM card, eSIM, and activating your travel data.

Can I use my Zero1 2GO Travel Data eSIM as Dual SIM?

Yes, eSIMs work as dual SIM. That means you can continue using your regular SIM card while using your Zero1 2GO Travel Data eSIM. 

Important: 

Just because your phone has dual SIM technology doesn’t necessarily mean it’s eSIM compatible. Also note that you may incur roaming charges for voice calls or SMS. 

Please check that your phone model appears in our eSIM-compatible device list.

No, you can buy an eSIM whenever you want. 

After making your purchase, you can wait for up to 90 DAYS before scanning the QR code via your data settings.

Download the eSIM via your data setting once at your destination. Download requires internet access, so ensure you are connected to Wi-Fi before you begin the process.

The eSIM will automatically activate by connecting to your destination's mobile network. Please check your plan’s page on 2go.zero1.sg for which network(s) to connect to. 

Important Notes:

  • Android users have the option of scanning or uploading an image of the QR code into their data settings to download their eSIM. Please save the QR code into your phone's photo album prior to travel.
  • iPhone users only have the option of scanning the QR code to download their eSIM. Please save the QR code on another device or print out the QR code prior to travel.

Setting up an eSIM requires an internet connection, so make sure you are connected to Wi-Fi before you start this process. 

  • Add the new data plan - Go to Settings > Mobile Data > Add Data Plan. If you can’t see these options in your phone’s settings menu, this may be due to the model of phone you have. You can find the specific steps for your phone in the guide linked bellow.
  • Scan the QR code - Your data settings will trigger your camera so you may scan the QR code provided to you after purchasing your eSIM. The easiest way to do so is to have your QR code open on your computer screen or printed out so you can scan it with your phone. If you have not received the QR code, please contact our customer support team so we may assist you.
    • Android users have the option of scanning or uploading an image of the QR code into their data settings to download their eSIM.
    • iPhone users only have the option of scanning the QR code to download their eSIM.
  • Start the download - Once you have scanned the QR code, your eSIM will begin downloading into your phone. Tap on “Confirm” if prompted to start downloading.
  • Choose a name for your data plan - You can now give your data plan a name to differentiate it from your other SIM card. We recommend calling it "2GO Travel".
  • Set up your eSIM for data only - Choose the new data plan as the option for “data only”. This means that you can keep your original SIM for calls and text messages.
  • Turn on mobile data and data roaming - Once at your destination, you may activate your plan by turning on both mobile data and data roaming in your phone’s settings.

Your Zero1 2GO Travel Data eSIM can only be activated on up to three devices. 

If you delete the eSIM from your phone, you can download it again (up to a maximum of 3 times). If you are a frequent traveler, you may wish to retain the eSIM on your phone.

Some phones may allow you to do so but most phones will only allow you to have one eSIM active at any one time. 

Yes. Set your device to use your SIM card for phone calls and text messages, and your Zero1 2GO Travel eSIM for data. 

Please remember that if you leave your main SIM card activated, your network provider may apply data roaming charges to make or receive phone calls, and to send or receive text messages. So, make sure the settings are correctly applied. 

For eSIMs: 

  1. Download the eSIM via your data setting once at your destination. Download requires internet access, so ensure you are connected to Wi-Fi before you begin the process.
  2. The eSIM will automatically activate by connecting to your destination's mobile network. Please check your plan’s page on 2go.zero1.sg for which network(s) to connect to. 

For Physical SIMs: 

  1. Once you arrive at your destination, install the physical SIM – this can be in sim slot 1 for phones that only support one sim or in sim slot 2 if the device supports more than 1 sim slot 
  2. Activate the new SIM by connecting to the network to get the most out of your plan and avoid losing any days of connection. 

The number of days in the plan will start counting down when you activate your SIM by connecting to the network of your chosen destination, not when you install it. 

Whether you are using a physical SIM or an eSIM, your data plan only begins the moment you activate it on your phone by connecting to the network of your chosen destination. 

Scanning the QR code and downloading/installing your eSIM, or installing the physical SIM, does not start the service.  

However, once you activate it, and the SIM attaches to the network, the number of days in your plan will start counting down.
