What should I do if I lose my activation QR code?
You can't really lose it - your QR code is in your order confirmation email, and also in the install pop-up on the website. To reopen it any time before activation, tap "Install eSIM" in your order email, or sign in at esimno.com and go to Profile > My eSIMs > Install. Both show the QR code together with the one-tap install link and the manual SM-DP+ / activation code. Note the install codes are one-time-use: once the eSIM is installed on a device they can't be reused - reopen the installer (My eSIMs > Install) to display a fresh QR if you need one.
Will the eSIM affect my phone's battery life?
Running two SIM lines (physical + eSIM) uses slightly more battery than one, since the phone monitors both networks. The difference is usually 5-10% over a full day. To minimize impact, disable the line you're not actively using or turn off cellular data on the inactive line.
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.
Can I keep my WhatsApp number while using an eSIM?
Yes. Your WhatsApp number stays linked to your home SIM, so all your chats, contacts, and groups remain unchanged. WhatsApp uses data (not the SIM line directly) for messages and calls, so it works seamlessly over your eSIMno data.
Can I get a refund after purchase?
Refunds are not available once an eSIM has been installed or activated - install codes are one-time-use, so an installed eSIM is considered used even if no data has been consumed. If you have not installed your eSIM yet and want a refund, contact support within the refund window stated at checkout. We recommend reviewing plan details carefully before purchase to avoid any issues.
Can I install multiple eSIMs on the same phone?
Yes. Modern iPhones and Android devices support multiple eSIM profiles - typically 5 to 8 stored profiles, with 1 or 2 active simultaneously. You can install eSIMs for different countries and switch between them in settings without removing any.
How do I top up my Internet eSIM?
To top up your Internet eSIM data, log in to the 'My eSIMs' section in the eSIMno Center on our website or mobile app. Select the eSIM you want to top up and follow the on-screen instructions to add more data without losing your current connection.
How long is the validity of the Internet eSIM plans?
The validity of eSIM plans varies from 7 days to 90 days depending on the plan you choose. Lifetime options are also available for travelers who don't want their data to expire after a fixed period.
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.
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.
Can I buy an eSIM for someone else as a gift?
Yes. Purchase the eSIM with your own details, then forward your order confirmation email - or share the "Install eSIM" link from it - with the recipient so they can install it on their own phone (the email contains the QR code and the manual SM-DP+ / activation codes). Make sure their device is eSIM-compatible first - installation usually cannot be reversed once completed.
Will the eSIM work on my iPad?
Yes, if your iPad model supports eSIM. iPad Pro (3rd generation and later), iPad Air (3rd generation and later), iPad mini (5th generation and later), and standard iPad (7th generation and later with cellular) all support eSIM. Installation works the same way as on iPhone.
Do I need to remove my eSIM after my trip?
You don't have to remove it. Once your data plan expires, the eSIM simply stops providing data. You can leave the dormant profile on your phone and reuse it next time by purchasing a new plan, or delete it from cellular settings to free up an eSIM slot.
What payment methods does eSIMno accept?
eSIMno accepts major credit and debit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and Google Pay. All transactions are processed through secure encrypted gateways, and we don't store full card details on our servers.
What should I do if I see a 'No network' message after activating my eSIM?
If you see a 'No network' message after activation, try these steps in order: (1) Toggle airplane mode on for 10 seconds, then off. (2) Confirm data roaming is enabled for the eSIM line. (3) Manually select a network in cellular settings. (4) Restart your phone. If the issue continues, contact eSIMno support via WhatsApp or email.
Do I need to deactivate my original SIM?
We recommend turning off cellular data and data roaming on your original SIM while abroad to avoid accidental roaming charges. You don't need to physically remove the SIM - just disable data and set the eSIM as your primary data line.
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 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.
Does the eSIM work on cruise ships or airplanes?
eSIMs use ground-based cellular networks, so they don't work in flight or at sea outside coastal coverage. They activate as soon as you connect to a partner network on land. For in-flight or maritime data, you'll need the airline or ship's onboard Wi-Fi.
What network speeds can I expect?
Most eSIMno plans connect at 4G/LTE or 5G speeds depending on local network availability and your device's capabilities. Speed varies by location, network congestion, and signal strength. In major cities and tourist areas, expect speeds comparable to local mobile carriers.
Should I enable data roaming for the eSIM?
Yes - you must enable data roaming for the eSIM line, even though there are no roaming charges. The eSIM connects to a local partner network and your phone treats this as roaming. Enable it: iPhone > Settings > Cellular > eSIMno line > Data Roaming ON; Android > Settings > Network > SIMs > eSIMno > Roaming ON. This setting only affects the eSIM, not your home SIM.
What data plans are available for the Internet eSIM?
eSIMno provides various data plans ranging from 1 GB to unlimited data, with options from 7 days to 90 days of service. Plans also include regional and lifetime options for travelers who want flexibility across multiple destinations.
