> Quick answer: Most modern iPhones can store 8 or more eSIMs but only run 2 at the same time. Android varies by brand: newer Pixels and Galaxies store several eSIMs and run 1–2 active. Travelers can keep their home number working while a travel eSIM handles data — and store extra plans for future trips.
If you travel a lot, this question matters more than it sounds. Knowing the difference between how many eSIMs your phone can *store* and how many it can *run at once* lets you stack country plans for a multi-stop trip, keep your home number alive, and never hunt for a SIM shop again.
Here's the full breakdown for 2026 phones.
How many eSIMs can an iPhone have?
Most iPhones from the iPhone 13 onward can store 8 or more eSIMs and keep 2 active at the same time. Older eSIM-capable iPhones (XS, XR, 11, and 12) can also store 8+, but they can only run one eSIM alongside the physical SIM.
Apple doesn't publish one exact storage number for every model — it depends on the size of each eSIM profile — but in practice, 8+ stored profiles is the norm, and some newer models hold even more.
A few iPhone specifics worth knowing:
- iPhone 13 and later: two eSIMs can be active at once (two lines, no physical SIM needed).
- iPhone 14 and later (US models): eSIM only — there's no physical SIM tray at all.
- iPhone XS to iPhone 12: one active eSIM + one physical SIM.
Stored eSIMs work a bit like saved Wi-Fi networks: they sit quietly on your phone until you switch one on. Not sure which group your phone falls into? Run it through our <a href="/compatibility">device compatibility checker</a> in a few seconds.
How many eSIMs can an Android phone have?
It depends on the model. Newer Google Pixel phones (Pixel 7 and later) and recent Samsung Galaxy flagships (S23 series and later, in most regions) can run two eSIMs at once. Most other eSIM-capable Androids run one active eSIM plus a physical SIM.
Storage limits also vary. Pixels and Galaxies typically hold at least 5–7 profiles, and many hold more. Budget and mid-range Androids with eSIM support usually store fewer.
The quickest way to check your own phone:
- Open Settings.
- Tap Network & internet (Pixel) or Connections (Samsung).
- Tap SIMs or SIM manager.
- Look for Add eSIM — if you see it, your phone supports eSIM, and this screen lists every profile you've stored.
What's the difference between stored and active eSIMs?
A stored eSIM is a saved plan that's switched off; an active eSIM is a live line that can connect right now. Think of it like apps: you can install many, but you only have a couple open at once.
| Stored eSIM | Active eSIM | |
|---|---|---|
| Connects to a network | No | Yes |
| Uses battery | No | Yes (same as any SIM) |
| Uses plan data or days | No* | Yes, once you start using data |
| How many your phone allows | Usually 5–8+ | Usually 1–2 |
*With TripoSIM, plan validity doesn't even start until your first data use — so a stored plan isn't burning days while it waits. More on that in our guide to <a href="/blog/when-does-a-travel-esim-start-and-expire">when a travel eSIM starts and expires</a>.
Can I use a physical SIM and an eSIM at the same time?
Yes — this is the classic dual SIM setup, and it's exactly how most travelers should run a travel eSIM. Your physical SIM keeps your home number reachable, while the eSIM handles all your data abroad.
Here's the setup that works almost everywhere:
- Keep your home SIM active for calls and texts — so bank codes and family calls still reach you.
- Set your travel eSIM as the data line.
- Turn data roaming off on your home SIM so it can't quietly rack up roaming charges.
TripoSIM plans are data-only, which fits this setup perfectly: your number stays on your primary SIM, and calls happen over WhatsApp, FaceTime, or any app you already use. For the full walkthrough, see our <a href="/blog/how-to-use-dual-sim-esim-travel">dual SIM guide</a>.
Can I store eSIMs for multiple countries at once?
Yes — and this is the superpower for multi-stop trips. Because phones store far more eSIMs than they run, you can load plans for every country on your route before you leave home.
A three-country trip might look like this:
- Before departure: buy and install eSIMs for Japan, Thailand, and Vietnam on home Wi-Fi (installing is easier with a strong connection — here's <a href="/install">how to install</a>).
- Land in Tokyo: switch on the Japan eSIM. The other two stay dormant.
- Fly to Bangkok: switch off Japan, switch on Thailand.
- Arrive in Hanoi: same again with the Vietnam plan.
Each plan only starts counting once you first use its data, so nothing expires while it waits its turn. With <a href="/destinations">179+ destinations to browse</a>, you can map out an entire itinerary this way. And if you'd rather carry one plan than three, regional eSIMs cover whole areas like Europe or Asia with a single profile.
Does storing extra eSIMs use battery or data?
No. A stored, switched-off eSIM is just a small file sitting on a secure chip in your phone. It doesn't search for networks, doesn't use data, and doesn't touch your battery. Only *active* lines use power — and even then, an eSIM draws no more than a physical SIM would (we bust that myth fully in <a href="/blog/does-an-esim-drain-your-battery">does an eSIM drain your battery?</a>).
What happens if I hit my phone's eSIM storage limit?
Your phone will ask you to delete an old profile before adding a new one. Delete carefully: removing an eSIM with an active plan usually kills that plan, because activation codes are typically single-use per device. Always delete expired plans first, and never delete one you're still using. If you're unsure whether a plan is finished, check its data balance before removing it — our <a href="/tools/data-calculator">data calculator</a> can also help you judge how much a plan should have left based on your usage.
Frequently asked questions
How many eSIMs can an iPhone 16 have?
It can store 8 or more eSIM profiles and keep two active at the same time. US models are eSIM-only, so both of your active lines can be eSIMs.
Can I have two active eSIMs and a physical SIM?
No mainstream phone runs three lines at once in 2026. You can have two active lines total — two eSIMs, or one eSIM plus one physical SIM — while extra eSIMs stay stored and switched off.
Do stored eSIMs expire while switched off?
The profile itself doesn't expire from sitting on your phone. With TripoSIM, the plan's validity clock only starts at first data use, so you can install weeks before a trip without losing a single day.
Will using two SIMs at once cause problems?
No — dual SIM is a standard, well-tested feature. Just make sure the right line is set for data and that roaming is off on your home SIM, or you may get surprise charges from your home carrier.
Can I share one eSIM between two phones?
No. An eSIM installs on one device, and its QR code is single-use per device. Each phone needs its own plan — see <a href="/blog/what-happens-to-your-esim-when-you-change-phones">what happens when you change phones</a>.
Does deleting an eSIM free up storage for a new one?
Yes, deleting a profile frees a slot right away. Just make sure the plan on it is fully used or expired first, because you usually can't reinstall it with the same QR code.
