JT supports eSIMs in smartphones and tablets, offering you greater flexibility and a more secure service.

What's an eSIM?

An eSIM is a virtual SIM card that’s pre-installed on newer devices, which removes the need to insert a physical SIM. They work just like physical SIM cards by storing the data your device needs to use the JT network.

Why choose an eSIM?

  • Getting started is faster: It makes setting up a new device quicker and simpler, plus if you already have an account with us and want to switch to eSIM, you don’t have to come in store or wait for a SIM to arrive in the post.
  • Dual SIM functionality: As most of the smartphones that currently support eSIMs also retain their physical SIM card slots, you can enjoy having two numbers on one device, perfect for managing everyday life, as well as business.
  • Security and safety: Our eSIM services have robust security features, like advanced encryption and authentication, making smartphones more secure against fraud.
  • eSIMs are greener: No physical SIM card means no plastic, plus there’s no need for any postage and packaging.
What devices can I use eSIM with?

The following devices are compatible with eSIM:

  • All iPhone models from XS onwards (XS, 11, 12, SE 2020 etc).
  • All Google Pixel devices from Pixel 3 onwards (3, 3A, 4, 4A, 5 etc).
  • Many new Samsung devices (including S20, S21, Z Flip, Fold, Note).
  • New Oppo devices (including N2 Flip, Fine X5 & X5 Pro, Fine X3 Pro).
  • The Motorola Razr (2020) is eSIM only.
  • Our eSIMs are available for some cellular tablets.
If you're not sure if your device supports eSIM, please check its specifications with the manufacturer.


Can I keep my old number when swapping to a JT eSIM?

Yes! You can transfer your mobile number from a traditional SIM card to an eSIM and vice versa in the same way you would when changing from one mobile network to another.  

What is Dual SIM?

Dual SIM means that there are two SIM slots within the device – a physical SIM card and an eSIM. 

With a Dual SIM device you can have two phone numbers and two different plans on one device; ideal for switching between ‘personal’ and ‘work’ without needing to carry two devices around with you.  

You can have a Dual SIM device but only have one SIM card active.
