Introduction
You’ve just landed in a new country, and the first thing you need is internet. No Google Maps to find your hotel. No messaging app to let someone know you arrived. No way to check if your ride is waiting outside.
If you’re on Android, setting up an eSIM is one of the easiest ways to get connected — and you can do it before you even leave home. This guide walks you through exactly how to set up an eSIM on Android, step by step, whether you’re using a Samsung Galaxy, Google Pixel, or any other compatible Android device.
What You Need to Know First
Before you start, make sure your Android phone actually supports eSIM. Most flagship devices from the last few years do — including Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many mid-range devices from brands like Motorola and Xiaomi. If you’re not sure, check your phone’s specs online or look in your settings under “Network & Internet” for any eSIM-related options.
You’ll also need a Wi-Fi connection to download your eSIM profile, so connect to your home network before your trip. Make sure your phone isn’t carrier-locked either — some carrier-locked devices restrict eSIM activation on other networks.
Finally, have your eSIM activation QR code or confirmation details ready. If you’ve already purchased a plan from our eSIM store, you’ll have received everything you need by email. Keep it handy — you’ll use it in the next section.
Step-by-Step: Set Up an eSIM on Android
The exact menu names can vary slightly depending on your Android version and manufacturer, but the core steps are the same. Here’s how to activate your eSIM on Android:
1. Open your network settings
Go to Settings → Network & Internet (or Connections on Samsung). Tap on “SIM cards” or “Mobile network.” You should see an option to add a new SIM or eSIM.
2. Add your eSIM
Tap the “+” button or “Add eSIM.” When prompted, choose “Scan QR code” or “Enter activation code manually.” If you have a QR code from your eSIM provider, scan it with your camera. If you received an activation code, type it in carefully.
Pro tip: A QR code is the fastest method. Make sure you’re in good lighting and that the entire code is visible on screen.
3. Confirm and download
Your phone will connect to the carrier server and download the eSIM profile. This usually takes 30 seconds to a minute. Don’t close the screen or switch apps while it’s downloading.
4. Label your SIMs
Once activated, you’ll want to label your SIMs so you can tell them apart. Name your eSIM something like “Travel Data” and your primary SIM “Home.” This makes switching between them much easier later.
5. Set your data preferences
Under your SIM settings, choose which SIM handles mobile data, calls, and text messages. For most travelers, you’ll keep calls and texts on your regular SIM and route mobile data through your eSIM. That way you get affordable data abroad without losing your familiar number.
6. Turn on data roaming (if needed)
Some eSIM plans require data roaming to be enabled. Go to Settings → Network & Internet → Mobile network → Roaming and toggle it on. Don’t worry — you’ll only be charged according to your eSIM plan, not your home carrier’s roaming rates.
7. Test your connection
Open a browser or an app that uses data to confirm everything’s working. Try loading a webpage or searching for something on Google. If the page loads, you’re all set!
On Samsung Galaxy devices specifically, you may see “Connections” instead of “Network & Internet,” and the eSIM option sits under “SIM card manager.” On Google Pixel, the path is usually Settings → Network & Internet → SIMs → Download a SIM instead.
Common Issues and How to Fix Them
Even with a straightforward process, a few things can trip you up. Here are the most common issues Android users run into when setting up an eSIM — and how to fix them.
“No eSIM option in my settings”
If you can’t find any eSIM menu, your phone might not support it, or it could be carrier-locked. Check your device’s official specs to confirm eSIM compatibility. If your phone was purchased through a carrier, contact them to request an unlock.
QR code won’t scan
Make sure you’re scanning the full QR code — not a cropped screenshot. If scanning still fails, look for the manual activation code option instead. You can enter the SM-DP+ address and activation code by hand, which achieves the same result.
eSIM downloads but shows “No service”
This usually means the eSIM profile downloaded correctly but hasn’t connected to a local network yet. Try toggling airplane mode on and off, or restart your phone. If you’re in a remote area, you may need to wait until you reach a location with coverage from your eSIM’s partner network.
Can’t switch data to the eSIM
Go to Settings → Network & Internet → SIM cards and make sure your eSIM is set as the preferred SIM for mobile data. On Samsung devices, this is under Connections → SIM card manager → Mobile data.
Activation code says “already used”
Each eSIM activation code can only be used once. If you accidentally deleted the profile, you’ll need to contact your eSIM provider for a replacement code. Most providers can reissue one quickly if you explain the situation.
Frequently Asked Questions
How long does it take to set up an eSIM on Android?
The whole process takes about two to five minutes. Scanning the QR code and downloading the profile is the fastest part — most of your time will be spent navigating to the right settings menu.
Can I keep my regular phone number while using an eSIM?
Absolutely. Your primary SIM stays active for calls and texts while your eSIM handles data. You can even set different SIMs for different functions in your Android settings.
What Android phones support eSIM?
Most Samsung Galaxy models from the S20 onward support eSIM, as do Google Pixel 3 and newer devices. Many mid-range phones from Motorola, Xiaomi, and other manufacturers also include eSIM support. Check your specific model’s specs to be sure.
Do I need to be on Wi-Fi to activate my eSIM?
Yes, you need an internet connection to download the eSIM profile. Connect to Wi-Fi before you start the setup process. Once the profile is installed, you can switch to mobile data.
What happens when my eSIM data runs out?
When your data allowance is used up, your eSIM will stop providing internet access. You can usually purchase a top-up or a new plan from your eSIM provider. Some plans auto-renew, so check the terms before you buy.
Conclusion
Setting up an eSIM on Android is simpler than most people expect. With a compatible phone, a Wi-Fi connection, and your activation QR code, you can be online in a new country within minutes of landing.
The key is to do it before you travel. Activate your eSIM at home, test it, and arrive ready to go. If you’re looking for a reliable eSIM solution with coverage in dozens of countries, explore our store to find the right plan for your next trip.
