Can an iPhone 17 have two eSIMs active at once?

Yes. Two lines can be active simultaneously, so you can keep your home number reachable for calls and OTPs while a travel eSIM carries your data.

Can an iPhone 17 have more than two eSIMs installed?

Yes. Eight or more profiles can be stored on the device, and each appears in Settings > Cellular with its own switch. Only two may be turned on at any moment.

Do inactive eSIM profiles cost anything or use data?

No. A profile that is switched off has no network connection and cannot consume data. It simply occupies a slot in the phone's secure element.

Does the iPhone 17 have a physical SIM tray?

It depends on where it was purchased. Models sold in the United States are eSIM-only with no tray, while many other markets still ship a nano-SIM tray alongside eSIM. Look at the side of the device or check Settings > Cellular for a 'Physical SIM' entry.

How many eSIMs can an iPhone 17 have?

Short answer

An iPhone 17 can store eight or more eSIM profiles and keep two of them active at the same time. Storage is the limit on how many plans you can keep saved; two active lines is the limit on how many can connect to a network simultaneously.

Check it yourself: Settings > Cellular lists every profile saved on the device, each with its own on/off switch. Turning on a third line prompts you to switch one off — that prompt is the two-active limit in action.

Stored versus active

Stored profiles — eight or more can live on the device. Old travel plans stay saved and switched off, costing nothing.
Active lines — two at a time, in any combination of physical SIM and eSIM on models that still have a tray.
US models — eSIM only, so the two active lines are always two eSIMs.
Switching an old plan back on takes a single toggle; no reinstall and no new QR code.

The typical traveller setup

1
Line 1: your home number
Active for calls and SMS one-time passcodes.
2
Line 2: the travel eSIM for this trip
Active and set as the cellular data line.
3
Lines 3+: past trips
Left installed but switched off. Reactivate any of them on your next visit if data remains.

Multi-country trips

If you are visiting several countries, you have two options: install one eSIM per country and switch the active line as you cross borders, or buy a single regional plan that covers the whole route. One regional plan is simpler and avoids losing connectivity while you fiddle with settings in an airport.
