Add your plan on Android
Add your plan through the app, or from Settings with the QR code if you bought on knowroaming.com. Either way takes about a minute on Wi-Fi, and it's best done the day before you fly. On a Samsung Galaxy, use Add your plan on Samsung instead.
Before you start
KnowRoaming plans work on iPhone XS and later and on most Android flagships released since 2019. Your phone also needs to be carrier-unlocked. Check your exact model on the device compatibility page before you buy.
It's fine to add your plan days before you fly, as long as you have a stable connection to do it. Leave data roaming off until you land. Nothing on your plan starts until you connect abroad, so there's no downside to adding early and switching on later.
You need a stable Wi-Fi or data connection for about a minute. Prefer to watch? A reusable eSIM for every trip shows how KR.One works.
Through the app
- Open the KnowRoaming app and go to My plans.
- Select your device and tap Add a plan. For a new device, tap Add another device and plan.
- On "Let's complete auto setup," tap Continue.
- On "Install your eSIM," tap Continue. Keep the app open and stay connected; it takes about a minute.
- When it's done, follow the two steps on screen to turn on data roaming.
- Tap Continue, then Done. Your plan is on your phone.
The app can add the plan, but only your phone's settings can switch roaming on. See Turn on data roaming for your plan on Android.
If it gets interrupted, you'll see "Couldn't add your eSIM to this device." Your plan is safe, nothing was charged, and you can try again from My plans.
From Settings with the QR code
Use this if you bought your plan on knowroaming.com and don't have the app. Your QR code is in your confirmation email and on your order page. Open it on another screen, or have the SM-DP+ address and activation code ready to type.
- Open Settings and tap Network & internet.
- Tap SIMs. On older Android versions this shows as Mobile network.
- Tap Add eSIM. On Pixel this shows as Add SIM, then Download a SIM instead.
- Tap Scan QR code and point the camera at the code.
- Can't scan it? Choose Enter code manually and type the SM-DP+ address and activation code from your email.
- If Android asks which SIM to use for mobile data, keep your home SIM for now; switch when you land.
- Optional: tap the new eSIM under SIMs and give it a name you'll recognize, such as KnowRoaming.
The labels above are Pixel's. Other brands word them differently; the section below says where to look.
When you land
Turn the KnowRoaming line on, turn on data roaming for it, and point your data at it. The taps are in Turn on data roaming for your plan on Android. Give your phone a minute to connect once you land. Still nothing? Switch on Airplane Mode for 30 seconds, then switch it off again.
Setting your APN
Most destinations need no APN. If yours is on this list, add it before you connect:
Destination
APN
Global, Israel, Kuwait, Morocco, Mauritius, Middle East, Qatar, Saudi Arabia, South Africa
knowroaming
Argentina, Brazil, Canada, Chile, Colombia, Costa Rica, Ecuador, Mexico
tn1
Bahamas, Caribbean
altanwifi
Australia, China, India, Indonesia, Japan, Philippines, Singapore, South Korea, Taiwan
kroly
Europe, United States
No APN needed
Enter the value in lowercase with no spaces. On Android: Settings > Network & internet > SIMs > your KnowRoaming eSIM > Access Point Names (older versions: Mobile network > Advanced > Access Point Names). If the APN is listed, select it. If not, tap the menu icon, choose New APN, enter any name you'll recognize, enter the value under APN, then save and select it.
Good to know
- Your plan is data only, with no phone number, calls, or SMS. Calls and texts keep using your home number.
- Your plan starts when you connect in a supported country, not when you buy. Your validity days count from that first connection. Unused data expires at the end of your validity period. It doesn't roll over.
- Data Saver holds back apps on mobile data. Turn it off in Settings > Network & internet > Data Saver while you travel.
- When you get home, turn data roaming off and set your data back to your regular SIM, so you don't pick up roaming charges. Your KnowRoaming plan stays on your phone, ready for your next trip.
- Settings names and screens vary a little by brand and Android version. Checked on a Pixel on Android 16.
Still not working?
If the add itself stops or fails, see Adding your plan is stuck: what to do and "Cellular plan cannot be added" and other add errors. If the plan is on your phone but nothing loads after you land, see eSIM not working: no data after landing.
Still not working? Message us on WhatsApp at +1-888-357-7347 and include four things: your ICCID, your order number, your phone model and OS version, and what you've already tried.
Foire aux questions
How to use an eSIM while backpacking is surprisingly simple. First, ensure your phone is unlocked and eSIM-compatible. Then, download the provider's app (like KnowRoaming's). You can choose your plan and add the eSIM digitally through the app, often by scanning a QR code. Once added, just enable data roaming for your eSIM, and you're ready to go, no physical cards or airport kiosks needed.
No swapping SIM cards, no kiosk queues at the airport, set it up once and it's ready every time after.
With KnowRoaming, setup takes less than five minutes. Using the automatic setup in the KnowRoaming app, you can download and add your eSIM in just a few taps. This makes it one of the fastest and most reliable ways to get connected before your trip.
Simply add the eSIM profile on your unlocked, eSIM-compatible device before you travel. Once you arrive in a supported country, turn on your eSIM, and you'll be connected!
