How many eSIMs can an iPhone have? By model

How many eSIMs on iPhone: 8 stored, 2 active

An eSIM is a digital SIM card built directly into the iPhone: no physical card to insert, the plan installs as a software profile. And the confusion about the number comes from two different figures. The first is storage: how many eSIM profiles your phone keeps in memory. The second is activation: how many lines work at the same time. The answer to "how many eSIMs on iPhone" depends on which one you actually mean.

On storage, Apple states on its official support page that eSIM lets you manage eight or more eSIMs on a compatible iPhone. In practice, you can keep your main line, your old travel plans and several spare data plans in memory, then activate the one you need.

On activation, the limit is two simultaneous lines. On the iPhone 13 and later, both lines can be eSIMs. On earlier models (XS, XS Max, XR, 11, 12), Dual SIM only works by combining a physical SIM card with an eSIM.

Compatibility starts with the iPhone XS, XS Max and XR: no earlier model supports eSIM. To check your exact model, we listed every eSIM-compatible iPhone in a dedicated article.

How many active eSIMs by iPhone model

The number of active eSIMs comes down to one dividing line: before or after the iPhone 13. Here is the breakdown, generation by generation.

iPhone XS, XS Max and XR: the first eSIM-compatible models. One active eSIM at a time, plus a physical nano-SIM for the second line.

iPhone 11 and iPhone SE (2020 and 2022): same behaviour, one active eSIM plus a nano-SIM.

iPhone 12: still a single active eSIM, even though several profiles can be stored. The second line has to go through the physical card.

iPhone 13 and iPhone 14: the real turning point. Two active eSIMs simultaneously, eight or more profiles in memory. iPhone 14 models sold in the United States have no SIM tray and are eSIM-only.

iPhone 15 and iPhone 16: two active eSIMs, eight or more stored profiles. In Europe the nano-SIM tray remains; in the United States these models are 100% eSIM.

iPhone 17 and iPhone 17e: their French spec sheets list Dual SIM (nano-SIM and eSIM) with Dual eSIM support for both models. Two active lines, either physical + eSIM or two eSIMs.

iPhone Air: eSIM only, everywhere in the world. The official spec sheet lists Dual eSIM with two active eSIMs and capacity for eight or more. No SIM tray at all.

Why use several eSIMs on an iPhone?

Three concrete use cases justify several eSIMs on the same phone: travel, separating work and personal life, and optimising your data plans.

The most common case is travelling abroad. You keep your home line active to receive banking verification texts and stay reachable on your usual number, and you add a local eSIM for data, without paying your carrier's roaming rates. In Japan for instance, a local data plan costs a fraction of standard roaming rates.

Second use case: two numbers on one iPhone. A work line and a personal line, each with its own label, without carrying two phones. Both numbers can make and receive calls and texts.

Third use case: juggling several data plans based on price. An unused eSIM profile costs nothing while it sits in storage: you can keep a backup plan in memory and only activate it when your main line has no coverage.

For the travel line, specialised eSIM providers sell data plans by country or region, with no commitment. Airalo offers the biggest catalogue of destinations. Holafly focuses on unlimited data, subject to a fair use policy. Saily adds a built-in VPN to its app. voilà, a French provider, positions itself on value for money, with some of the lowest prices per GB recorded on our comparator, an eSIM that is easy to install with an easy-to-use app, and human customer support, 24/7.

The right habit is still to compare these eSIM providers on price per GB for your exact destination: none of them is the cheapest everywhere.

How to activate and switch between two eSIMs on iPhone

Everything happens in Settings, then Cellular (or Mobile Data). That is where you activate a new eSIM, label your lines and switch between them.

For activation, three methods depending on your provider: scanning a QR code, going through the provider's app, or using quick transfer from an old iPhone. The plan then shows up as an extra line in your settings.

Once both lines are active, give them clear labels, for example "Personal" and "Travel". You then choose which line is your default number for calls, and above all which line carries mobile data. When travelling, your local line should carry the data, not your home line.

To switch between stored profiles: Settings, Cellular, tap the line you want, then "Turn On This Line". The deactivated profile stays in memory, ready to be reactivated later. Apple details the whole procedure on its Dual SIM with eSIM support page.

The limits to know before stacking eSIMs

Having several eSIMs does not mean stacking everything. Four limits come up systematically, and the first is the least known.

One data connection at a time. Even with two active lines, your iPhone only connects to one mobile data network at any given moment, as Apple puts it. Two 10 GB plans do not make a 20 GB plan: your phone uses one or the other.

Carrier locking. To use two plans from two different carriers, your iPhone must be unlocked. An iPhone bought subsidised from a carrier can refuse a competitor's eSIM until it is unlocked.

Regional variants. iPhone 14, 15, 16 and 17 models sold in the United States have no SIM tray. In mainland China, only the iPhone 17e and iPhone Air support eSIM. In Hong Kong and Macao, some models take two physical nano-SIMs. If you buy an iPhone abroad, check the local spec sheet first.

Your plan's compatibility. Your carrier must support eSIM for the line to activate. That is the case for the main European carriers and for every travel eSIM provider on the comparator.

The rat's advice: before you leave, turn off data roaming on your main line and leave "Allow Cellular Data Switching" off. Otherwise your iPhone may dip into your home line's roaming while you think you are browsing on your local plan, and the bill stings.
