iPhone Dual SIM Plans: How To Use Dual SIM & The Best Value Plans

You can activate the dual-SIM functionality on your iPhone for £6/month. It allows you to have two phone numbers at the same time.

If you’re using a fairly recent iPhone, it will have support for dual-SIM functionality using eSIM technology. This allows you to have two phone numbers at the same time on your iPhone (e.g. one work phone number and another personal phone number). With dual-SIM, you can also benefit from coverage in more places along with access to offers such as freebies or inclusive sport and entertainment subscriptions.

In this article, we’ll look at how you can use the dual-SIM functionality on your iPhone. We’ll start by looking at the benefits of dual-SIM and the  iPhones that are compatible with the technology. We’ll then compare the best dual-SIM compatible plans available from UK mobile networks like EE, O2 and Vodafone.

Using Dual SIM on the iPhone

In 2018, Apple added dual-SIM technology to the iPhone. You can now use it on all new models of the iPhones including the iPhone 11, the iPhone 12, the iPhone XS, the iPhone XR and the iPhone SE 2020.

With dual-SIM technology, you can have two phone numbers at the same time on your iPhone (which can either be from the same mobile network or from two different mobile networks). For instance, many people use dual-SIM technology so they can have both their work phone number and their personal phone number together on one device.

If you’re using dual-SIM on the iPhone, one of your phone numbers will need to be on an eSIM plan. You can currently get an eSIM plan from £6/month in the UK with compatible plans available on EE, O2 and Vodafone.

Why Use Dual SIM?

There are four main advantages to using dual-SIM technology on an iPhone:

1. You can have two phone numbers at the same time. For instance, you can have both your work phone number and your personal phone number at the same time on the iPhone. This allows you to keep your calls and messages separate without needing to carry two phones around at all times.
2. You can access mobile coverage in more places. You can access coverage from two different networks at the same time. For instance, you might still be able to get coverage on the second network even where there’s no coverage available on the first network.
3. You can benefit from lower prices when you travel. For instance, you can buy a local SIM card when you travel abroad. Alternatively, you can take advantage of inclusive roaming offers such as Vodafone’s Global Roaming Plus (81 destinations) and O2’s Travel Inclusive Zone (75 destinations).
4. You can access more exclusive customer offers. For instance, you’ll get access to VeryMe Rewards when you add a dual-SIM plan from Vodafone. Alternatively, you can get things like inclusive Disney+ when adding a plan from O2 or inclusive BT Sport when adding a plan from EE.

In the following table, you can compare eSIM-ready plans available from EE, O2 and Vodafone. All of these plans can be used with dual-SIM functionality on your iPhone.

If you choose a plan from EE or O2, you’ll initially be sent a plastic SIM card through the post.
