How do I activate my Nomad eSIM?
The Nomad eSIM is activated from the phone's network settings once installed: scan the QR code or add it from the app, and the plan is turned on by activating "mobile data" or "roaming" upon arrival at the destination. Installing it does not activate it (source: nomadesim.com, accessed August 2, 2026).
This difference—install first, activate later—is what most confuses first-time eSIM users, and it's why this guide clearly separates both steps, using instructions published by Nomad in their own help center and on their website, all with a consultation date.
Do you need the Nomad app to install the eSIM?
It is not mandatory. According to Nomad's installation guide, the app facilitates the process (especially the "add automatically" option), but the QR code and manual data entry work independently, without needing to download anything (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026).
In practice, this leaves you with three paths, from most to least automatic:
| Method | App required | When suitable |
|---|---|---|
| Automatic (Add automatically) | Yes | You purchased from a compatible phone and want the most guided process |
| QR Code | No | You purchased from a laptop or want to install from another device with a camera |
| Manual (SM-DP+ and activation code) | No | The QR doesn't scan or the phone's camera is not available at that moment |
All three methods are described in Nomad's help center (source: nomadesim.com/help-center, accessed August 2, 2026). None require being logged into the app during your trip: the app is convenient, not essential.
Installing the Nomad eSIM on iPhone, step by step
To install by QR code on an iPhone, Nomad instructs to go to Settings > Cellular > Add Cellular Plan (eSIM) and scan the QR code received by email or appearing in the "Manage" section of the account (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026). If the iPhone doesn't detect the camera or you prefer not to use it, on the same screen there is an "Enter Details Manually" option, where you copy the SM-DP+ Address and activation code from the confirmation email.
- Connect to a stable Wi-Fi network before starting (installation needs data, and you don't have an active plan at the destination yet).
- Go to Settings > Cellular > Add Cellular Plan (eSIM).
- Scan the QR code or tap "Enter Details Manually" if you prefer that method.
- Name the line (e.g., "travel eSIM") to differentiate it from your main line.
- Leave the line installed, but do not activate it yet if you have not reached your destination.
Nomad's support itself reminds that the QR code is for one-time use: once scanned by one device, it will not work again on another (source: nomadesim.com/help-center, accessed August 2, 2026). It's important to keep this in mind if you plan to check it first "to see what it looks like" from the phone you actually want to install it on: that first scan can already consume the single available use, even if you cancel the installation halfway. It's safer to save the email with the QR and open it directly from Settings at the moment you are actually going to install it, instead of opening it earlier in the browser of the same phone.
Installing the Nomad eSIM on Android, step by step
On Android, the exact names of the menus vary by brand, but the general path documented by Nomad is Settings > Connections (or Network & Internet) > SIM card manager > Add mobile plan, and from there scan the QR code with the camera in the settings menu itself, not with the phone's general camera app (source: nomadesim.com/blog/how-to-install-esim-on-android, accessed August 2, 2026).
- Connect to Wi-Fi before starting the process.
- Open Settings and search for "eSIM" or go to Connections > SIM card manager.
- Tap "Add mobile plan" or the "+" icon and choose to scan QR code.
- Scan from that menu, not from the general photos or camera app on the phone.
- If scanning repeatedly fails, use the manual entry option with the SM-DP+ Address and activation code from the email.
As with iPhone, the Nomad app is not mandatory to complete any of these steps: it is an additional layer for managing the already installed eSIM (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026).
What to do if the Nomad QR code doesn't work?
Nomad recommends, in that order: confirming that the scan is done from the network settings menu and not from the phone's general camera; verifying that there is an active Wi-Fi connection throughout the process, because installing an eSIM consumes data; and, if the QR still won't scan, using manual entry with the SM-DP+ Address and activation code received by email (source: nomadesim.com/help-center, accessed August 2, 2026).
"Your eSIM QR code can only be used once. If you need help reinstalling it, please contact us" — this is how Nomad, in its own help center, summarizes the most common reason why a QR "stops working" midway through installation (source: nomadesim.com/help-center, accessed August 2, 2026).
If after trying both methods (QR and manual) the problem persists, Nomad's suggested route is to contact their support directly through the app itself or the help center, as they are the ones who can re-issue the code or review the account.
Installing is not the same as activating
This is the point where most people get confused when using an eSIM from any provider, not just Nomad. Installing the eSIM profile on your phone is a technical step you can do days before your trip, even from home. Activating is different: it's when the data plan starts running, and it's usually best to do that once you're at your destination, not before.
According to Nomad's own documentation, installing the profile in advance does not usually advance the plan's expiration date; the countdown begins when you activate the line (by enabling mobile data/roaming) at your destination (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026). If you see the eSIM as installed but "no service" while you are still in your home country, this is expected behavior: most travel eSIMs do not work until they detect a network at the destination.
You can read more about this distinction, applied to any eSIM and not just a specific provider, in our general eSIM installation guide and in the explanation of what an eSIM is and how it works internally.
Common errors when installing a Nomad eSIM
Most problems when installing an eSIM—from Nomad or any other provider—are recurrent. Before writing to support, it's worth ruling out these points, which coincide with those documented in Nomad's own help center for their QR:
- Scanning the QR with the camera app instead of the settings menu. The eSIM QR is not a link: it must be scanned from within Settings > Mobile Data (or the equivalent menu on Android).
- Trying to install without Wi-Fi. The process requires data, and if you're traveling without an active plan on your phone yet, there's no way to complete it with mobile data.
- Opening the QR more than once before installing it. Since it's for single use, checking it first on one device and then trying to install it on another can invalidate it.
- Confusing "installed" with "active." If the phone is still in the home country, it's normal not to have service: this is resolved upon arrival and activating data at the destination, as explained in the previous section.
- Using a phone not compatible with eSIM or locked by the operator. Not all models or all operating system versions support eSIM; it's advisable to check this before purchasing, not after.
If you want a broader list of frequent issues with any eSIM (not just during installation, but also when traveling with it), you'll find it in common eSIM problems, and to initially confirm if your model is compatible, see eSIM-compatible phones.
Nomad eSIM vs. physical SIM: what changes in installation
The fundamental difference between installing an eSIM and buying a physical SIM at the airport lies in the "when" and "where." A physical SIM requires having the card in hand, finding a physical point of sale, and sometimes waiting in line or showing identification upon arrival. An eSIM is installed before traveling, using Wi-Fi, from the phone itself, and is only activated upon arrival.
| Aspect | eSIM (Nomad or other provider) | Physical SIM |
|---|---|---|
| When it's installed | Before traveling, from home, with Wi-Fi | Upon arrival at the destination (or purchased in advance and picked up there) |
| Physical object | None: digital profile | Physical card that needs to be inserted |
| Risk of loss | Not applicable | The card can be lost or damaged |
| Reinstallation on another phone | Depends on the provider; Nomad's QR is for single use | The physical card can be moved between compatible phones |
| Required phone | Must support eSIM | Must support SIM size and be unlocked |
If you are still unsure between an eSIM and a physical SIM for your next trip, the complete comparison—with advantages and limitations of each—is in eSIM vs. physical SIM. And if you want to understand the difference between using a data eSIM and activating your usual operator's roaming, you'll find it in eSIM vs. roaming.
Nomad vs. other travel eSIMs: objective comparison
Here we are not going to say that one provider is "better" in general, because that is neither verifiable nor honest: it depends on the destination, the phone, and how comfortable you find the installation process. What can be compared are concrete data that each provider publishes on their own channels, with a consultation date.
| Criterion | Nomad (according to nomadesim.com, accessed August 2, 2026) | PuraSIM |
|---|---|---|
| Declared coverage | More than 200 destinations | More than 200 destinations |
| Installation | QR, manual, or automatic via app; QR is for single use | QR or manual, guided from purchase confirmation |
| Requires Wi-Fi to install | Yes | Yes |
| Installing activates the plan immediately | No: installing and activating are distinct steps | No: activation takes about 1 minute when you decide to turn it on |
| Window to activate from purchase | Not specified on consulted pages | 180 days from purchase |
| Support channel | Help center with articles and contact from the app/website | Email and WhatsApp, 24/7, in all supported languages |
What Nomad does well, and which is reflected in their own documentation, is clearly distinguishing between installing and activating, and offering three installation methods (automatic, QR, and manual) so that a failing QR doesn't leave you without an alternative. Where our sheet compares more directly is in the ample window for activation from purchase and in having a WhatsApp support channel in addition to email, available 24/7. If your priority is that broad window and WhatsApp support, you can check eSIM plans for your next destination in our international eSIM collection.
Frequently asked questions
How do I activate my Nomad eSIM?
Install the profile (by QR, automatic, or manual) and then, once at the destination, activate it by turning on mobile data or roaming for that line from Settings. Installing does not activate the plan by itself (source: nomadesim.com, accessed August 2, 2026).
Do you need the app for Nomad eSIM?
No. The app helps with automatic installation, but the QR code and manual entry work without downloading any app (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026).
How do I install the eSIM card?
It is not a physical card: it is installed as a digital profile from Settings > Mobile Data (iPhone) or Settings > Connections > SIM card manager (Android), by scanning a QR code or entering the data manually.
How can I activate my eSIM step by step?
Connect to Wi-Fi, install the profile by QR or manually, name the line, and wait until you are at your destination to activate mobile data or roaming for that line. Detailed steps by operating system are in the previous sections of this guide.
Can I install the Nomad eSIM before traveling?
Yes, and it's even recommended: install beforehand, with Wi-Fi, and activate upon arrival, because installing usually doesn't advance the plan's expiration (source: nomadesim.com/esim-installation-guide, accessed August 2, 2026).
What happens if the QR code no longer works?
Most likely it has already been used once, because Nomad's QR is for single use. In that case, you must resort to manual installation with the SM-DP+ Address and activation code, or contact their support to have it reviewed (source: nomadesim.com/help-center, accessed August 2, 2026).
Can any phone install a Nomad eSIM?
No: the phone must support eSIM and, in some cases, be unlocked by the operator. Before purchasing, it is advisable to check the list of eSIM-compatible phones.
Can the Nomad eSIM be moved to another phone after installation?
According to their own help center, the QR code is for single use, so once installed on one device it does not automatically transfer to another (source: nomadesim.com/help-center, accessed August 2, 2026).
Conclusion
Installing a Nomad eSIM is not essentially different from installing any other travel eSIM: Wi-Fi before departure, QR or manual data from the correct Settings menu, and activation reserved for when you are at your destination. Where people often fail is not in the technology, but in confusing "installed" with "active" or in exhausting the single use of the QR code too early.
If you are comparing options for your next trip and what matters most to you is having a time buffer to activate (180 days from purchase) and being able to write via WhatsApp in addition to email if something goes wrong, with 24/7 support in multiple languages, you can check the available destinations in our international eSIM collection. And if you are still not sure what an eSIM is exactly or if your phone supports it, that basic information is in our definitive eSIM guide for travelers.
