Your QR code will usually get your travel eSIM installed in a minute or two. But when the camera will not scan it, the email is on another device, or you simply prefer to enter the details yourself, manual setup is the right backup plan. Knowing how to add eSIM manually means you can get connected without hunting down a SIM store after landing.
Manual installation uses the same eSIM plan and the same network access as a QR-code installation. You are simply entering the activation information directly into your phone instead of scanning it. For travelers, that small distinction can save a lot of time when Wi-Fi is limited or setup needs to happen quickly.
What you need before adding an eSIM manually
Start with three checks: your phone must support eSIM, it must be carrier-unlocked, and it needs a stable internet connection for installation. An unlocked phone can use a travel eSIM alongside, or instead of, your home carrier line. A compatible but carrier-locked device may show the eSIM options but still reject the plan.
Have your eSIM activation details open on a second screen or copied somewhere secure. Depending on your provider, these details may include an SM-DP+ address, an activation code, and sometimes a confirmation code. They are normally shown beneath the QR code in your order email or account instructions.
Do not share these details. An eSIM can generally be installed only once, and someone else using the activation code could prevent you from adding it to your own phone. If you are setting up before departure, use dependable home or hotel Wi-Fi rather than waiting for airport Wi-Fi.
One more detail matters: installation and plan activation are not always the same thing. Some travel plans begin their validity period when the eSIM is installed, while others begin when it first connects to a supported network at your destination. Check your plan instructions before installing days or weeks early.
How to add eSIM manually on iPhone
Apple menu names can vary slightly by iOS version, but the path is usually straightforward. Go to Settings, select Cellular or Mobile Data, then choose Add eSIM. If you see an option to use a QR code, open it first. Look for Enter Details Manually near the bottom of that screen.
Enter the SM-DP+ address exactly as supplied, then enter the activation code. If a confirmation code was included, add that too. These fields are case-sensitive in some cases, so avoid adding spaces before or after copied text. Tap Next and allow your iPhone a moment to download the eSIM profile.
Once it appears, give the line a clear label such as “Travel Data” or the destination name. This makes it much easier to manage if you keep your regular number active for calls and texts. You can leave the travel line turned on but wait to make it your data line until you arrive, depending on the plan’s activation policy.
If the phone asks which line should be used for cellular data, select the newly installed travel eSIM when you are ready to use it. For most travel-data plans, keep your home line as the default for voice and iMessage if you need your usual number, but turn off data roaming on that home line to avoid accidental charges.
How to add eSIM manually on Android
Android instructions differ by brand, but the setting is typically under Settings, then Network & internet, Connections, or SIM manager. Look for SIMs, Mobile network, or Add eSIM. Select the option to add a mobile plan.
Most Android phones first open a QR scanner. Look for wording such as Need help?, Enter it manually, or Use activation code instead. The exact text depends on the phone manufacturer and Android version. Enter the SM-DP+ address and activation code from your eSIM instructions, then confirm the download.
After installation, name the new SIM so you can identify it easily. In SIM manager or Mobile network settings, choose the travel eSIM as your preferred mobile-data SIM. If your phone has a setting called Allow data switching or Switch mobile data automatically, turn it off. This prevents the device from quietly switching back to your home line if the travel signal drops for a moment.
Some Android devices also require you to turn on Data roaming for the travel eSIM. This sounds counterintuitive, but it is normal for many international eSIM plans because they connect through local partner networks. Enable roaming only on the travel eSIM, not your home SIM.
Set your travel eSIM up for data when you arrive
An installed eSIM is not always immediately online. Once you reach your destination, turn on the travel line and select it for cellular data. Make sure cellular data is enabled, airplane mode is off, and the travel eSIM’s data roaming setting is on if your plan instructions require it.
Your phone should find a supported network automatically. Give it a few minutes, especially after a long flight or after moving between countries on a regional plan. Restarting the phone can also prompt a fresh network registration.
Avoid deleting your eSIM just because it does not connect instantly. Deleting removes the profile, and many activation codes cannot be reused. First check that you are physically in a covered destination, that the correct line is selected for data, and that roaming is enabled on the travel line.
For travelers using eSIMGo, the plan instructions sent with your purchase provide the activation details needed for manual entry. Keep that email available until you have confirmed the plan is working.
Common manual eSIM setup problems
If your phone says the activation code is invalid, copy the address and code again rather than typing them from memory. A missing character, an extra space, or placing the activation code in the wrong field can cause the error. Also confirm that you are using the details for the plan you purchased, not a sample code from a generic device guide.
If the eSIM installs but shows no service, verify that the plan covers your current country. Regional plans may have specific included destinations, and a plan can install successfully even when you are outside its coverage area. Next, check your cellular settings: travel eSIM selected for data, mobile data enabled, data roaming enabled on that eSIM, and automatic data switching disabled.
If the Add eSIM option is missing entirely, your device may not support eSIM, may be locked by a carrier, or may have reached its active eSIM limit. Some phones can store multiple eSIM profiles but use only a limited number at the same time. Turn off an unused line before trying again, but do not delete a plan you may need later.
A weak connection can interrupt the download as well. Switch to reliable Wi-Fi, restart the phone, and repeat the process only if the device confirms that the earlier installation did not complete. If it says the plan is already installed, look in your SIM or Cellular settings before attempting another activation.
A better way to prepare before takeoff
Install your travel eSIM while you still have dependable internet, then label it and review your data settings before leaving. Keep your home number available for calls if needed, but make the travel eSIM your data line only when the plan is meant to start. That approach gives you control over timing while reducing the chance of roaming surprises.
Manual setup is not complicated once you know where to look. Save your activation details, enter them carefully, and let your travel eSIM handle the data while you focus on the trip ahead.
