What is an eSIM?

A SIM card is basically a small identification chip that allows you to connect your mobile phone to your mobile network, send texts, make calls and access 3G, 4G and 5G internet.

You can swap SIM card between phones to transfer your mobile access.

An eSIM is exactly the same, but it’s electronic rather than physical – so you can’t lose it.

It’s a digital SIM card that allows you to activate your mobile data plane without the need for a physical card.

Most phones support one SIM card – and sometimes two – but you can store many eSIMs on a single phone.

You can transfer eSIMS between phones (like upgrading).

And you can also convert physical SIM cards to eSIM cards.

Does the iPhone 14 have an eSIM?

Many iPhone models support eSIMs, including the new iPhone 14 and iPhone 14 Pro.

In fact, US buyers can pick up a version of the new iPhone without a physical SIM card tray.

But iPhones back to the iPhone XS, iPhone XS Max and iPhone XR also support eSIMs.

A single iPhone can support up to two phone numbers and eight eSIMs.

You also need to make sure you’re on a wireless cellular network that supports eSIMs.

And to set up an eSIM for the first time, you need to be connected to a Wi-Fi network.

How to convert a physical SIM card to an eSIM on iPhone

If you have an Apple iPhone, you can easily convert your physical SIM to an eSIM.

Here’s what you need to do…

  • 1. Go to Settings > Cellular Data
  • 2. Select Convert to eSIM
  • 3. Tap Convert mobile data plan
  • 4. Tap Convert to eSIM
  • 5. Wait for your eSIM to activate
  • 6. Remove the physical SIM card from your iPhone
  • 7. Reboot your iPhone

If Convert to eSIM isn’t available, it means your carrier doesn’t support the feature.

You can also enter the eSIM information manually.

Here’s what to do…

  • 1. Contact your mobile operator and get the eSIM details
  • 2. Go to Settings and then either Cellular or Cellular data
  • 3. Now tap on Add mobile data plan
  • 4. Then enter all the details manually at the bottom of the iPhone screen

If you have a very old iPhone, you won’t be able to take advantage of eSIM technology.

And if you don’t connect to WiFi, you won’t be able to set up your eSIM.
