Can You Install Two eSIMs From Different Apps on One Phone?

Yes, on most phones sold since 2022. iPhone 13 and later, and Pixel 7 and later, can run two eSIMs active at once, so a co:sim eSIM and a second provider's eSIM can both live on the same device. Most older or budget Android phones support only one active eSIM plus one physical SIM, so a second app there means swapping, not running both together.

#What's the Difference Between Storing and Activating an eSIM?

Installing an eSIM and activating it are two different things, and the confusion between them is where most "can I have two?" questions come from. Almost every eSIM-capable phone can store several profiles at once, often eight or more, downloaded from as many different apps as you like. What's limited isn't storage, it's how many of those stored profiles can be active (connected to a network) at the same time.

Apple's own support page confirms that iPhone 13 and later "support Dual SIM with two eSIMs," meaning two eSIM profiles, from two entirely different providers if you want, can both be active simultaneously. Earlier models (iPhone XS through iPhone 12) top out at one active eSIM paired with one physical SIM (Apple Support). There's a further catch even on a two-eSIM iPhone: Apple's page also states "your iPhone can use one cellular data network at a time," so only one of the two active eSIMs actually carries data at once; you switch between them (manually, or automatically with Allow Cellular Data Switching turned on), rather than both streaming data in parallel.

Google Pixel follows a similar split. Pixel 7 and later can run "2 eSIM profiles at once" if the carrier allows it; on other Pixels and most other Android phones, Dual SIM Dual Standby means one physical SIM plus one eSIM, capped at a single active eSIM (Google Pixel Help). This dual-eSIM capability comes from a chip-level feature called Multiple Enabled Profiles, added in Android 13, which device makers have to specifically build support for; not every Android 13+ phone includes it just because the OS supports it in principle (Android Open Source Project).

#Does Installing a Second eSIM Delete the First One?

No. Installing an additional eSIM profile, from co:sim or any other provider, doesn't touch profiles you've already stored. Each one sits on the device independently until you delete it yourself, and switching which one is active is a Settings toggle, not a reinstall. This is also why keeping an old, expired eSIM installed costs nothing: it just sits inactive until you need to reference it or remove it.

#Why Install a Second eSIM From a Different Provider?

The practical case is redundancy, not indecision. If your first eSIM's underlying network has a bad day in a particular region, or you're crossing into a second country your current plan doesn't cover, having a second provider's eSIM already installed means switching in Settings rather than scrambling for Wi-Fi to download a new one on arrival. This works especially well on a two-active-eSIM phone, where both stay reachable without you ever needing to pick a "winner" between providers. A co:sim data-only eSIM installs from an emailed QR code in seconds, so it's a low-friction one to keep as either your primary plan or your backup alongside another provider's.

A trip that spans multiple countries, like a Japan leg followed by a stop elsewhere, is a common reason travelers end up with two providers installed side by side rather than deleting and reinstalling at every border.

#FAQ

#Can I install eSIMs from two different companies on the same phone?

Yes. There's no technical restriction tying an eSIM-capable phone to a single provider's app; you can download and store eSIM profiles from as many different companies as you want, one after another, as long as your phone has free storage slots for profiles (typically eight or more, regardless of brand). What determines whether they can both be active at the same time, rather than just stored, is your specific phone model: iPhone 13 and later and Pixel 7 and later support two active eSIMs, while most older or budget Android phones cap out at one active eSIM alongside a physical SIM. Installing a co:sim eSIM alongside an existing provider's eSIM works exactly the same way as installing any second profile, with no need to remove or pause the first one first.

#Will a second eSIM interfere with my first one?

No, as long as you leave the first one enabled rather than disabling it during setup. Each eSIM profile is a separate, isolated identity on the network; installing a second one doesn't overwrite, pause, or affect the first one's validity, data balance, or install deadline in any way, even if both come from different providers with different billing rules. The only interaction between them is which one your phone treats as active for calls, texts, or data at any given moment, which you control from Settings, not from either provider's app. If you're installing a co:sim eSIM as a second profile alongside an existing one, its own validity clock and data allowance run independently of whatever else is already on the phone.

#Do I need two active eSIMs, or is storing a second one enough?

For most travelers, just having the second eSIM stored and ready is enough; you only need it "active" once you actually want to switch to it. A phone limited to one active eSIM can still store a second provider's profile in advance and switch over in Settings within seconds when you need it, no new QR code, app download, or Wi-Fi search required at the worst possible moment. A phone that supports two active eSIMs simultaneously (iPhone 13 and later, Pixel 7 and later) adds the option of leaving both reachable at once, which matters most if you want automatic failover rather than a manual switch mid-trip. Either way, installing a co:sim eSIM ahead of a trip means it's sitting ready before you need it, active or not, with no extra cost for keeping it stored.

#Does this work the same way on Android as on iPhone?

The concept is the same, but which phones support two active eSIMs differs. On iPhone, that's models from the iPhone 13 onward, confirmed on Apple's own support page. On Android, it depends on both the phone and the carrier: Pixel 7 and later can support two active eSIMs if the carrier allows it, while most other Android phones, including many recent mid-range models, are limited to one active eSIM plus one physical SIM under a mode called Dual SIM Dual Standby (DSDS). Storing multiple eSIM profiles from different apps, including a co:sim eSIM, works on essentially any eSIM-capable Android phone regardless of this limit; it only affects how many of those stored profiles can be connected to a network and carrying data at the same moment.

#If my phone supports two active eSIMs, do both get data at the same time?

Not quite. Even on a phone built for two active eSIMs, like an iPhone 13 or later, Apple's own documentation is explicit that "your iPhone can use one cellular data network at a time." Both eSIMs stay registered and reachable for calls and texts, but only one carries data unless you switch, either manually in Settings or automatically if you've enabled Allow Cellular Data Switching, which hands data over to whichever line has coverage. So a second eSIM from a different provider is best understood as an instantly available switch rather than two simultaneous data connections. For a co:sim eSIM used as that second line, switching to it takes the same few taps as switching between any two active profiles.

#Do I need to remove my current eSIM before adding a new one?

No, and doing so isn't necessary or recommended if you want the redundancy benefit in the first place. Installing a new eSIM, whether from co:sim or another provider, is additive: your phone adds it to the list of stored profiles without touching whatever's already there, including its data balance and remaining validity. Removing an existing eSIM only makes sense if you're permanently done with that plan or you've genuinely hit your phone's storage limit for profiles, which is rare given most current models support eight or more stored at once. If you're adding a co:sim eSIM specifically as a backup to an existing plan from another provider, leave the first one installed exactly as it is and simply toggle between the two in Settings whenever you actually need to switch.
