How do I top up my Montserrat eSIM?
To top up your Montserrat 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 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.
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.
What is the price range for the Montserrat eSIM plans?
Prices commence at $15.90 and vary according to data allowance and plan duration. Larger data plans and longer durations cost more, but the per-GB rate decreases with bigger packages.
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.
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.

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.
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.
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.
How do I activate the Montserrat eSIM?
Your eSIMno order confirmation email contains your QR code, your SM-DP+ address and activation code, a one-tap install link, and an "Install eSIM" button - so you can install right from the email. The same options are also on the website: sign in at esimno.com and go to Profile > My eSIMs > your plan > Install. To install, use any ONE of these methods: (1) on the phone you are setting up, tap the one-tap install link/button (iPhone on iOS 17.4+ or Android 9+); (2) use the QR code - because a phone cannot scan its own screen, show this QR on another screen (computer/tablet) or a printout and scan it WITH the phone you are setting up (never with someone else's phone, or the eSIM would install on that phone); or (3) enter the SM-DP+ address and activation code manually. Your Montserrat eSIM activates automatically when you connect to a local network at your destination.
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 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.
