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.
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.
Which eSIM is best for travelling to Internet?
eSIMno is an excellent option for travelers heading to Internet. We offer a diverse range of eSIM plans - including regional, local, and lifetime options - with reliable coverage on local networks.
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.
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.
Is unlimited data really unlimited?
Unlimited plans provide unlimited data at high speed (4G/5G) up to a fair-use threshold defined per plan. Beyond that threshold, speeds may be reduced to 128 Kbps for the remainder of the validity period - still usable for messaging and basic browsing, but slower for streaming and video calls.
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.
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.
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 happens if I pause my trip and return home?
Your eSIM keeps its validity period running whether you're using it or not - pausing your trip doesn't pause the timer. If you return home, the eSIM stays dormant on your device until you travel again or it expires. You can disable it in cellular settings to avoid accidental usage.
Can I use my SIM card and eSIM at the same time?
Yes. On dual-SIM devices (most modern iPhones and Android phones), you can run your physical SIM and the eSIM simultaneously. Use your home SIM for calls and SMS, and the eSIM for mobile data. Keep in mind that leaving your home SIM active may trigger roaming charges if you use it for calls or texts abroad.
How do I delete an eSIM I no longer need?
On iPhone: Settings > Cellular > tap the eSIM line > Remove eSIM. On Android: Settings > Network & Internet > SIMs > tap the eSIM > Erase. Deleting the eSIM frees up a profile slot. Make sure you don't need it anymore - once deleted, you can't reinstall the same profile.
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.
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.
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.
How can I purchase the Internet eSIM?
You can purchase your eSIM directly from the eSIMno website - select a Internet plan and complete the payment. Within minutes you'll receive an order confirmation email that contains everything you need to install: a QR code, a one-tap install link, the SM-DP+ address and activation code, plus an "Install eSIM" button. You can install straight from that email, or sign in anytime and go to Profile > My eSIMs > Install to get the same options.
When should I set up my eSIM?
A Wi-Fi connection is required to install your eSIM, so we recommend setting it up before you leave home. Activation can happen later, either right before departure or after you land at your destination - but the initial QR scan needs Wi-Fi.
Can I use the eSIM on more than one device?
Each eSIM profile is tied to a single device once activated. If you need data on multiple devices (e.g., phone and tablet), you can either purchase separate eSIMs for each device or use the Personal Hotspot feature on your phone to share data with other devices.
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.
Can I use the eSIM right after purchase or do I need to wait?
Yes - you can install it immediately after purchase. Your order email arrives within minutes and contains the QR code, a one-tap install link and the manual codes, plus an "Install eSIM" button; you can also sign in > My eSIMs > Install any time. Installing right away 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 Data Roaming off until you are ready to start; if your plan covers the country you are in right now, turning the line on starts the countdown immediately.
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.
Will my home phone number receive calls while I use the eSIM?
Yes - if your home SIM stays installed and active, calls and SMS to your home number arrive normally. The eSIM only handles data; voice service stays on your home line. Just remember that incoming calls and texts to your home number while abroad may trigger roaming charges from your home carrier.
