How to Use Multiple eSIMs on One Phone

The number of eSIM profiles you can store depends on your device. iPhones running iOS 16 or later can store eight or more eSIM profiles, though only two can be active simultaneously. On models with a physical SIM tray (iPhone 14 and earlier outside the US), you can run two eSIMs plus one nano-SIM, giving you three total lines. The iPhone 15 and 16 series in the US are eSIM-only, so all your lines come from stored eSIM profiles.

Android devices vary more. Google Pixel phones from the Pixel 7 onward support multiple eSIM profiles with two active at once. Samsung Galaxy S24 and S25 series can store up to five eSIMs. Other manufacturers like Sony, Motorola, and OnePlus support eSIM, but the number of stored profiles and active lines differs by model. The GSMA, the organization that developed the eSIM standard, maintains specs that allow for far more profiles than most phones currently support.

💡 Pro Tip

Stored eSIMs don’t use battery or data when inactive. You can keep profiles for countries you visit regularly and just toggle them on when you land. Think of it like having a drawer full of SIM cards, except they live inside your phone.

Adding a new eSIM on iPhone takes about two minutes. Open Settings > Cellular (or Mobile Service in some regions) and tap Add eSIM. You’ll see options to scan a QR code from your carrier, use a carrier app, or transfer an existing eSIM from another device. Most travel eSIM providers like Airalo and Holafly give you a QR code right after purchase. If you need a more detailed walkthrough, our step-by-step iPhone eSIM setup guide covers the entire process.

Once scanned, your phone downloads the eSIM profile. You can label each line with a custom name like “Work,” “Personal,” or “Japan Trip” to keep them organized. This matters when you have four or five profiles installed because the default labels (“Primary,” “Secondary”) get confusing fast.

After installation, go back to Settings > Cellular to choose which line handles calls, which handles data, and whether your phone should switch data lines automatically when one has poor signal. Apple calls this Dual SIM functionality, and it works well for keeping a home number active while using a local data plan abroad.

Android’s eSIM interface varies by manufacturer, but the general process is similar. On a Pixel, go to Settings > Network & Internet > SIMs and tap the + button. On Samsung, it’s Settings > Connections > SIM Manager > Add eSIM. You’ll scan a QR code or enter an activation code manually.

Android 13 and later improved multi-eSIM handling significantly. Our complete Android eSIM setup guide covers the process for all major manufacturers. You can rename each profile, set default lines for calls and SMS separately from data, and switch between profiles without deleting them. The Android Open Source Project documentation outlines how the eSIM manager works at the system level, which is useful if you’re troubleshooting activation issues.

One important difference from iPhone: some Android devices only allow one eSIM to be active at a time alongside a physical SIM. Check your specific model’s specs before buying multiple eSIM plans, because you might not be able to run two eSIMs simultaneously. Samsung’s eSIM support page lists which Galaxy models support dual active eSIMs.

When you have multiple eSIMs active, your phone needs to know which line to use for what. Both iOS and Android let you assign defaults: one line for outgoing calls and texts, another for cellular data. You can also override this per-contact on iPhone, so calls to your boss go through your work number while everything else uses your personal line.

Data is where it gets interesting for travelers. You can keep your home carrier’s eSIM active for calls and texts (so people can still reach you) while routing all data through a cheaper local eSIM. This avoids roaming charges on data while keeping your number available. The FCC’s guide to international roaming explains how roaming charges add up, which is a good motivator to get this setup right.

If you enable “Allow Cellular Data Switching” on iPhone (or equivalent on Android), your phone will automatically use the other line’s data when your primary data line has poor connectivity. This is helpful in areas with spotty coverage but can lead to unexpected charges if one of your lines has expensive data rates.

✓ Best practices for multiple eSIM management

• ✓ Label each eSIM clearly (country name, carrier, or purpose)
• ✓ Turn off lines you’re not using to save battery
• ✓ Set your home line as the default for calls and texts
• ✓ Use a local eSIM for data when traveling to avoid roaming fees
• ✓ Screenshot your eSIM QR codes before deleting profiles in case you need to reinstall

Frequent business travelers: If you fly between the US, UK, and Germany regularly, you can keep an eSIM for each country stored on your phone. When you land in Frankfurt, disable your US data line and activate your German one. Total time to switch: about 15 seconds. No fumbling with tiny SIM trays at the airport.

Work and personal separation: Instead of carrying two phones, use one device with two eSIM profiles. Your work line rings during business hours, and you can silence it on weekends without affecting your personal number. Both Apple and Google have built-in tools for managing dual-line behavior.

Digital nomads moving between countries: Someone spending three months in Thailand, then two in Portugal, then a month in Mexico can store eSIM profiles for each destination. According to a Statista report on digital nomads, over 35 million people worldwide identified as digital nomads in 2025, and connectivity is consistently ranked as their top concern. We have a dedicated guide on the best eSIM plans for digital nomads if that’s your situation.

Backup connectivity: In areas where one carrier has weak signal, having a second eSIM on a different network gives you a fallback. This is particularly useful in rural areas or developing countries where no single carrier has complete coverage.

Multiple eSIMs aren’t without friction. First, only two lines can be active at once on most phones. If you have eight eSIMs stored, six of them are dormant until you manually switch. This isn’t a huge inconvenience, but it does mean you can’t receive calls on all eight numbers simultaneously.

Second, some carriers still don’t support eSIM activation, particularly smaller regional carriers and MVNOs. The T-Mobile, AT&T, and Verizon all support eSIM in the US, but if you’re on a smaller carrier, check their support page before assuming you can go eSIM.

Third, transferring eSIMs between phones isn’t always seamless. Apple introduced eSIM Quick Transfer in iOS 16, which works between iPhones on the same Apple ID. But moving an eSIM from an iPhone to an Android (or vice versa) usually means contacting your carrier for a new QR code. Some travel eSIM providers don’t allow transfers at all, so you’d need to buy a new plan.

Finally, be careful about deleting eSIM profiles. On most devices, deleting an eSIM removes it permanently. You’d need a new QR code or activation code from the carrier to reinstall it. If you’re not going to use a profile for a while, disable it instead of deleting it.

📝 Important Note

Your phone must be carrier-unlocked to use eSIMs from different providers. Locked phones may only accept eSIMs from the locking carrier. If you bought your phone through a carrier contract, contact them about unlocking before purchasing a travel eSIM.

Not all eSIM providers are equally convenient when you’re managing several profiles. Airalo is popular with travelers because they offer plans for over 200 countries, and each one installs as a separate eSIM profile. Their app makes it easy to see which profiles you have installed and how much data remains on each.

Holafly focuses on unlimited data plans, which simplifies things if you don’t want to track usage across multiple profiles. Nomad eSIM and Maya are other solid options with good regional coverage plans that cover multiple countries under a single profile, reducing the number of eSIMs you need to install. If you’re unsure which plan type suits your usage, our guide on how to choose the right eSIM data plan can help.

For people who want one eSIM that works across many countries instead of installing a new one per destination, look at global providers like Google Fi or Ubigi. Google Fi works in over 200 countries with a single plan and eSIM profile, which means less profile management at the cost of slightly higher per-GB prices in some regions.

eSIM won’t activate: Make sure you’re connected to WiFi or have an active data connection on another line. The phone needs internet access to download the eSIM profile from the carrier’s server. If it still fails, check that your device is compatible with eSIM and that the carrier supports your specific phone model.

Calls going to the wrong line: Go into your SIM settings and verify which line is set as the default for voice calls. On iPhone, you can also assign specific contacts to specific lines, which prevents calls from going out on your data-only travel eSIM.

No data after switching eSIMs: Toggle the eSIM off and on again in settings. If that doesn’t work, check that data roaming is enabled for that specific line (Settings > Cellular > [your eSIM line] > Data Roaming). Also verify APN settings are correct, as some travel eSIMs require specific APN configurations that don’t always auto-populate. For more fixes, see our eSIM troubleshooting guide.

“eSIM limit reached” error: Delete profiles you no longer need. Remember, iPhones can store 8+ but the exact limit depends on the model and iOS version. If you’re at the limit, remove expired travel eSIMs to make room for new ones.

Switching your active eSIM takes less than 30 seconds on either platform. Here’s how:

On iPhone: Open Settings > Cellular. You’ll see all your installed eSIM profiles listed. Tap the one you want to activate and toggle “Turn On This Line.” Then go back and set it as your data line if needed. The switch takes a few seconds while your phone connects to the new carrier’s network.

On Android: Go to Settings > Network & Internet > SIMs (or Settings > Connections > SIM Manager on Samsung). Tap the profile you want to activate. You can set it as the default for data, calls, or texts. On Pixel phones, you can also long-press the internet quick settings tile to switch data lines quickly.

Some phones now support switching from the Control Center (iPhone) or Quick Settings (Android), which means you don’t even need to dig into the full settings menu. This is especially helpful at airports when you’re rushing to get connectivity after landing.
