What smartphones support eSIM?
Most modern devices support eSIM, including iPhone XS and later, Samsung Galaxy S20 through S25 series, Google Pixel 4 and later, Huawei P40 and later, and many recent iPads. Check our full compatibility list before purchasing to confirm your device is supported.
Can I share data from my eSIM with someone else's phone?
Yes, through Personal Hotspot. Activate hotspot on your phone, share the password, and the other device connects to your data. Data used by connected devices counts toward your eSIM plan, so monitor usage to avoid running out faster than expected.
Can I install my eSIM before traveling?
Yes - setting it up before your trip is the easiest approach. Your confirmation email contains the QR code, a one-tap install link and the manual SM-DP+ / activation codes (the same options are also available via sign in > Profile > My eSIMs > Install). While on Wi-Fi at home, install it with the one-tap link on your phone, or - to use the QR - show it on another screen or a printout and scan it with the phone you are setting up (not another phone). Installing does not start your plan: the validity countdown only begins when the eSIM connects to a mobile network inside your plan's coverage area. Keep the eSIM line and its Data Roaming off until you are ready to start - if your plan covers the country you are in right now, turning the line on connects and starts the countdown immediately, even if you do not browse anything. Please note: once installed, an eSIM is considered used and is no longer eligible for a refund.
How do I set up the eSIM on my device?
The fastest way is straight from your order confirmation email, which now contains - for each eSIM - the QR code, a one-tap install link, and the SM-DP+ / activation codes. On the phone you'll use, tap the one-tap install link; or, to use the QR, show it on another screen or a printout and scan it with that same phone (not another phone); or enter the codes manually. The email also has an "Install eSIM" button that opens your eSIM's detail page and launches the install pop-up (sign in if prompted), and you can reach the same pop-up anytime via Profile > My eSIMs > find your plan (shown as "Ready to install") > Install. After installing, turn Data Roaming ON for your eSIMno line (iPhone: Settings > Cellular; Android: Settings > Connections/Network) - without it the eSIM installs but shows no internet.

How can I check my data usage?
Log in to the eSIMno Center on our website or mobile app to see your remaining data balance and usage history. You can also check usage in your phone's cellular data settings - most devices show data consumed per line.
Will my eSIM work in airports immediately after landing?
Yes - eSIMs typically connect within seconds of switching off airplane mode at the gate. Major airports have strong cellular coverage from local partner networks, so you'll have data before reaching baggage claim. No setup needed at arrival.
How can I verify if my eSIM is activated?
There are two clear indicators: (1) your phone's status bar shows the local carrier name once you arrive at your destination, and (2) the data icon (4G, LTE, or 5G) appears next to the eSIMno line in your cellular settings. If neither shows up, toggle airplane mode off and on, or restart your phone.
Is the eSIM connection secure?
eSIM connections are as secure as standard cellular connections - encrypted by the carrier network. For added security on public networks (cafes, airports), use a VPN. The eSIM profile itself is digitally signed and can't be cloned like a physical SIM.
Will I get notifications when my data is running low?
Yes. eSIMno sends email and push notifications when you've used 50%, 80%, and 100% of your data allowance. You can also check usage anytime in the eSIMno Center or in your phone's cellular settings to track consumption in real time.
Can I switch the eSIM to a different phone after activation?
Generally no. Once an eSIM is activated on a device, it's tied to that device. If you switch phones, you'll need to install a new eSIM. Some carriers offer eSIM transfer features, but eSIMno plans don't currently support transfer between devices.
What customer support is available if I have issues?
eSIMno offers 24/7 support via WhatsApp and email. Our human support team - not bots - handles installation help, troubleshooting, billing questions, and refund inquiries. Most issues are resolved within minutes during business hours and within a few hours overnight.
Can I make phone calls or send SMS?
eSIMno is a data-only service, so you can't make traditional voice calls or send SMS through the eSIM line. However, you can use messaging and calling apps over data - WhatsApp, iMessage, FaceTime, Telegram, Signal, and Google Meet all work normally.
