eSIM support

Not all devices support eSIM yet. While compatibility is growing, only certain phones currently work with eSIM. Similarly, not all devices are currently 5G enabled. However, if your device is 5G compatible, any of our SIMs, including an eSIM, will support this.

To check if your device is eSIM or 5G compatible, please visit our Devices page or consult your device manufacturer’s specifications.

If your phone is dual SIM compatible, you can have both a physical SIM and an eSIM. How you activate dual SIM features will depend on the make of your phone, so we recommend checking the manufacturer’s website.

The benefits of dual SIMs include:

• 2 different phone numbers and plans on 1 device – great for business use
• A plan on 2 different networks - for this to work the phone needs to be unlocked, otherwise you can only have 2 different plans on the same network
• Adding a local data plan when you travel abroad (unlocked phones only)

Whether you already have an eSIM or not, Quick Transfer makes transferring your number between iPhones - or converting the physical SIM to an eSIM on your current iPhone - easy. Follow the simple instructions below:

If you ordered a new contract with an eSIM online or in store, please ensure you gave us the correct email address, as this is where we’ll send your QR code. If the email address is right, check your junk, spam, or promotions folder. If you still can't find the email, contact us.

If you ordered a replacement eSIM, the QR code and confirmation code will be available to view in your Three Business online account. 

If you ordered over the phone, or through a Three Business Sales Specialist, we’ll post your eSIM QR code. This will take up to 3-5 working days, and you won't need a confirmation code. 

Please note, the QR code is single use only. Once you've downloaded your eSIM profile to your phone, the QR code will no longer work.

Yes, eSIM functions just like a traditional SIM when connecting to a mobile network. As long as you have signal, you can use all services. However, you will need an internet connection to download the eSIM profile to your device during the initial setup via QR code.

eSIM offers the same reliable connection to the network as a traditional SIM card. However, since eSIM is embedded in your device, it can’t be lost or stolen, providing added security. For businesses, eSIM offers several advantages, including easier management, enhanced security, and quicker replacement compared to a standard SIM card. Additionally, there’s no need to swap out physical SIM cards when you upgrade devices.

Yes, you can transfer or port your existing number to an eSIM just as you would with a traditional SIM card.

If your account has roaming services enabled, you can use your eSIM to roam internationally just like with a traditional SIM card. This is subject to any Spend Caps or regulatory data caps that may apply.

No, an eSIM is an embedded chip within your device. You simply scan a QR code to download your network connection and activate the eSIM. Some devices support dual SIM functionality, allowing you to use both an eSIM and a traditional SIM. So you can have 2 numbers on 1 device.
