eSIM Installation Guide
Set up your eSIM in minutes. Please make sure you are connected to a stable Wi-Fi network before starting the installation.
We recommend installing your eSIM a few days before you travel, then switching on Data Roaming only once you land. This avoids surprises and lets you fix any issue while you still have your home connection.
Direct Install
The fastest way: one tap, right from the device you’ll travel with. No scanning needed.
Open the install email on your travel iPhone
On the iPhone you’ll use abroad, open the “Your eSIM is ready” email and tap “Install eSIM”. Your eSIM install page will open.
Tap “Quick Install”
On that page, tap the “Quick Install” button under your plan name. Your iPhone takes you straight to the add-eSIM screen.
Tap “Activate”
When the “Activate Your eSIM” window appears, tap “Activate” and follow the on-screen steps. On iOS 26 and later, if you’re asked which lines to keep on, choose “Travel eSIM and Current SIM”.
Label your new eSIM
Give it a name like “Travel eSIM” so it’s easy to find in Settings. If you skip this, your iPhone may call it Secondary or Business.
Turn it on when you arrive
Once you land, follow the steps in the “After installing” section below.
Direct Install works on iPhone with iOS 17.4 or later, opened on the same device. If the link doesn’t prompt anything, use the QR Code method instead.
Quick Install on Android
One-tap installation now works on many phones with Android 10 or later, including Samsung, Google Pixel and OPPO.
Open the email in Gmail
On the phone you’ll travel with, open the install email in Gmail or open the link in Chrome. Links opened from inside WhatsApp won’t work.
Tap “Install eSIM”, then “Quick Install”
On the install page that opens, tap the “Quick Install” button under your plan name.
Confirm the installation
Your phone opens the add-eSIM screen with the details already filled in. Tap “Download” or “Add” and follow the prompts.
Turn it on when you arrive
Once you land, follow the steps in the “After installing” section below.
This needs up-to-date Google Play services and may not work on every model yet. If nothing happens when you tap Quick Install, use one of the two methods below.
Scan QR Code
Best when you have a second screen handy: a laptop, another phone, or a printout.
Open the QR code on a second device
Display your QR code on a laptop, tablet, another phone, or a printed copy, not on the phone you’re installing to.
Go to your phone’s cellular settings
Go to Settings → Cellular → Add eSIM → Use QR Code.
Go to Settings → Network & Internet → SIMs → Add eSIM.
Scan through the Settings scanner
Point your camera at the QR code using the scanner built into Settings, not your regular Camera app.
Confirm and label your eSIM
Follow the on-screen prompts, then name it something like “Travel eSIM”.
Turn it on when you arrive
Once you land, follow the 3 settings in the “After installing” section below.
A QR code can only be scanned once. If you get an error saying the plan can’t be added, it’s likely already installed. Check your SIM settings instead of rescanning.
Manual Installation
For tablets, devices without a camera, or if QR scanning isn’t working.
Find your activation details
Your SM-DP+ Address and Activation Code are in your confirmation email, right below the QR code.
Choose manual entry
Go to Settings → Cellular → Add eSIM → Enter Details Manually.
Go to Settings → Network & Internet → SIMs → Add eSIM → Enter details manually.
Enter the address and code exactly
Copy and paste both fields carefully. A single extra space or missing character will cause it to fail.
Confirm and label your eSIM
Name it something like “Travel eSIM” so it’s easy to find.
Turn it on when you arrive
Once you land, follow the 3 settings in the “After installing” section below.
If manual entry keeps failing, switch to the QR Code method. It’s more reliable on most devices.
Turn your eSIM on: 3 quick settings
Installing the eSIM is only half the job. Most “it’s not working” cases happen because one of these settings is still off. Do this once you arrive at your destination.
Open your Mobile settings
Go to Settings → Mobile Service (called Cellular on some iPhones). Under SIMs, tap your eSIM. Its name depends on the label you chose; in this example it’s Secondary.
Turn on the line and Data Roaming
Switch on “Turn On This Line”, then scroll down and switch on “Data Roaming”. Without it the eSIM can’t connect abroad, and this is the most common reason it seems not to work. The page title may show a network name (for example Play), which is normal.
Choose the eSIM for Mobile Data
Go back, tap “Mobile Data” and select your eSIM line. Keep “Allow Mobile Data Switching” off so your phone doesn’t fall back to your home line’s expensive roaming.
Restart your iPhone
Restart once. Within a minute you should see a local network name and 4G/5G at the top of your screen.
Turn on the eSIM
Go to Settings → Connections → SIM manager (Samsung) or Settings → Network & Internet → SIMs (Pixel and most others). Turn on your Maxesimo eSIM.
Set it as your mobile data SIM
In the same menu, tap “Mobile data” and select your Maxesimo eSIM.
Turn on Roaming
Open the eSIM’s settings and switch on “Roaming”. Without it the eSIM can’t connect abroad.
Restart your phone
Restart once. Within a minute you should see a local network name and 4G/5G at the top of your screen.
Tip: turn off Data Roaming on your home SIM to avoid unexpected charges from your home carrier.
Never delete the eSIM from your phone. A deleted eSIM can’t be reinstalled, even with the same QR code. If something isn’t working, message us first.
Travelling to Türkiye? We recommend installing your eSIM before you arrive, as this is the most reliable way. If you’re already in Türkiye, try turning on a VPN before installing. A VPN solves this in most cases, but due to local network restrictions we can’t guarantee it will work on every network.
Still not working?
My eSIM shows “No Number”+
That’s normal. Our eSIMs are data-only, so they don’t come with a phone number. Your internet will still work.
It says “No Service”+
Make sure you’re in a country covered by your plan and that Data Roaming is on. Then switch Airplane Mode on for 10 seconds and off again, or restart. If it still shows No Service, try picking a network manually in the line’s Network Selection menu.
It says “No SIM”+
Your phone isn’t reading the eSIM profile. Restart once. If it still says No SIM, don’t delete the eSIM. Message us and we’ll check it from our side.
I have signal but no internet+
Check that your Maxesimo line is selected for Cellular/Mobile data and that Data Roaming is on. If both are correct, restart your phone. The APN is set automatically, so you don’t need to change it.
The install link or QR code doesn’t work+
Each eSIM can be installed only once. If you get an error, your eSIM is probably already installed. Check your Cellular/SIM settings for a line showing “No Number”.
I’m in Türkiye and the eSIM won’t install+
Turn on a VPN, then try installing again while connected to Wi-Fi. This works in most cases, but we can’t guarantee it on every network. If it still fails, message us and we’ll look into it together.
