TL;DR — Quick Answer
You’ve landed, your phone is hunting for signal, and the Nomad eSIM you carefully installed at home is just sitting there — stuck on “Activating…” or showing no service at all. Meanwhile, everyone around you is already texting their families that they’ve arrived.
Take a breath. In my experience helping readers troubleshoot travel eSIMs, the vast majority of Nomad activation problems come down to one of three things: a misunderstanding of how activation actually works, a single toggle that’s switched off, or a network handshake that needs a nudge. Almost none of them mean your eSIM is broken.
This guide walks through every fix in the order you should try them — fastest first — plus the specific error messages Nomad users run into and what each one really means.
First, Understand This: Installation ≠ Activation
This single misunderstanding causes more panic than every technical glitch combined.
When you scan Nomad’s QR code or use direct install, you’re installing the eSIM — adding the profile to your phone. That’s it. Activation is a separate event that happens later, when your phone connects to a supported local network at your destination.
So if you installed your eSIM at home and it shows “Not activated” or “Activating…” — that’s not a bug. That’s the system working exactly as designed. Nomad confirms this in their own documentation: in most cases, the eSIM can only activate once you’ve arrived at your destination.
| Status You See | What It Actually Means | Should You Worry? |
|---|---|---|
| “Installed” / “Not activated” (before travel) | Profile is on your phone, waiting for a supported network | No — completely normal |
| “Activating…” (before arrival) | Your phone can’t reach a supported local network yet | No — it’ll complete on arrival |
| “Activating…” (after arrival, 15+ min) | A setting is blocking the connection — usually roaming or data line | Fixable — follow the steps below |
| Activated but no internet | Connected to network, but data routing is misconfigured (APN, data line) | Fixable — check settings & APN |
| “Invalid QR code” / “Code no longer valid” | The eSIM was already installed once, or the code expired | Contact Nomad support |
| “Cellular plans from this carrier cannot be added” | Your phone is carrier-locked and can’t accept other eSIMs | Unlock your phone first |
Install your Nomad eSIM on Wi-Fi before leaving home, but keep the eSIM line turned off until you land. Installation needs internet; activation doesn’t need to happen until arrival. This way you’re not fighting airport Wi-Fi to scan a QR code.
The 3 Settings That Fix Most Activation Problems
Before any deep troubleshooting, verify these three toggles. In most “my Nomad eSIM won’t activate” cases I’ve seen, at least one of them is off:
Changed any of these? Restart your phone now. Settings changes often don’t take effect until the phone re-registers with the network from scratch.
Step-by-Step: Nomad eSIM Still Not Activating
If the three settings above are correct and you’re physically at your destination, work through these in order. Stop as soon as one works.
Boring, but genuinely the most effective single fix. A reboot forces your phone to scan for networks fresh and complete the activation handshake. Power fully off, wait 30 seconds, power back on. Give it 2–3 minutes after boot before judging.
Turn Airplane Mode on, wait 15 seconds, turn it off. This forces re-registration on the local network without a full reboot. It’s the quickest fix for an eSIM that connected once and then dropped.
Sometimes automatic network selection latches onto a carrier Nomad doesn’t partner with in that country. Fix it manually:
- iPhone: Settings → Cellular → your Nomad line → Network Selection → turn off Automatic → pick a network from the scan results
- Android: Settings → Connections → Mobile Networks → Network Operators → turn off auto-select → choose a carrier
Check your plan’s supported networks in the Nomad app first. If the first carrier fails, try the next. Once connected, you can switch back to automatic.
If your phone supports 5G, switch Voice & Data to 4G or LTE. Nomad recommends this for compatibility — some partner networks handle roaming devices far more reliably on LTE, and 4G speeds are still plenty for maps, messaging, and streaming.
If your eSIM shows as activated and you have signal bars but no internet, the APN (Access Point Name) is the usual suspect. Open the Nomad app, find your plan details, and compare the listed APN against what’s in your phone’s settings under the Nomad line → Cellular Data Network (iPhone) or Access Point Names (Android). Correct it manually if it doesn’t match, then restart.
Open the Nomad app and check two things: that your plan’s validity period has started (some plans begin counting from purchase or first connection), and that you haven’t burned through the data allowance. A finished plan looks exactly like a broken one — no service either way. Refresh the Manage page in the app for real-time status.
This is the one mistake you can’t undo. Nomad warns explicitly that deleting an active eSIM may permanently invalidate it, and reinstalling isn’t always possible since QR codes are typically single-use. Deleting and re-adding feels like a natural “have you tried turning it off and on again” move — resist it. Exhaust every other step and contact support first.

Decoding Nomad’s Error Messages
“Invalid QR Code” or “This Code Is No Longer Valid”
Nomad QR codes are generally one-time use. If you (or anyone) already scanned the code — even on another device, even if the install seemed to fail — it won’t work again. This also appears if you’re scanning an expired code from an old order. There’s no self-service fix here: contact Nomad support with your order ID, and they can verify the eSIM’s status and reissue if appropriate.
“Cellular Plans From This Carrier Cannot Be Added”
This one isn’t Nomad’s fault at all — it means your phone is carrier-locked and refusing all third-party SIM profiles. Check it yourself: on iPhone, go to Settings → General → About → Carrier Lock. It must say “No SIM Restrictions.” If it shows a carrier name instead, you’ll need to get your phone unlocked by your carrier before any travel eSIM will install. Our carrier unlock guides cover the exact process for every major US carrier.
Stuck on “Activating…” Forever (iPhone)
iPhones in particular love to sit on “Activating…” when no supported network is reachable. If you’re at your destination with the right settings, run steps 1–4 above. If you’re still at home, ignore it — it cannot finish activating until you arrive, and forcing it won’t help.
iPhone vs Android: Where the Settings Live
| What You Need to Do | iPhone | Android (varies by brand) |
|---|---|---|
| Turn eSIM on/off | Settings → Cellular → [Nomad plan] → Turn On This Line | Settings → Connections → SIM Manager |
| Set data line | Settings → Cellular → Cellular Data → select Nomad | SIM Manager → Mobile Data → select Nomad |
| Enable roaming | Settings → Cellular → [Nomad plan] → Data Roaming ON | Mobile Networks → Data Roaming ON |
| Manual network selection | Settings → Cellular → [Nomad plan] → Network Selection | Mobile Networks → Network Operators |
| Switch to 4G/LTE | [Nomad plan] → Voice & Data → LTE | Mobile Networks → Network Mode → LTE/4G |
| APN settings | [Nomad plan] → Cellular Data Network | Mobile Networks → Access Point Names |
| Check carrier lock | General → About → Carrier Lock | Varies — try inserting another carrier’s SIM |
Your phone must be both eSIM-compatible and carrier-unlocked. iPhone XS/XR and newer, Galaxy S20 and newer, and Pixel 3 and newer support eSIM — but a locked phone fails regardless of model. Apple’s official guide to setting up an eSIM on iPhone is worth a bookmark if you’re new to eSIMs entirely.
How Nomad’s Activation Compares to Other Travel eSIMs
If you’re wondering whether this hassle is unique to Nomad — it isn’t. Activation-on-arrival is how nearly all travel eSIMs work. Here’s how the experience compares across the big three:
| Feature | Nomad | Airalo | Holafly |
|---|---|---|---|
| Activation trigger | Connect to local network at destination | Connect to local network at destination | Connect to local network at destination |
| Install method | QR code, direct install, or in-app | QR code, direct install, or in-app | QR code or direct install |
| Plan style | Fixed data (1GB–unlimited on select plans) | Fixed data packages | Mostly unlimited data plans |
| Support channels | Live chat (app + web), email | Live chat, email | 24/7 live chat, WhatsApp |
| Re-install after delete | Usually not — eSIM may be invalidated | Case-by-case via support | Case-by-case via support |
| Coverage | 200+ destinations | 200+ destinations | 200+ destinations |
The takeaway: switching providers won’t spare you the activation dance. Learning the settings once pays off with every travel eSIM you’ll ever use.
Before Your Next Trip: The 5-Minute Prevention Checklist
Every fix in this guide is easier to avoid than to perform at a baggage carousel. Run this checklist at home, on Wi-Fi, the day before you fly:
- Confirm “No SIM Restrictions” in Settings → General → About (iPhone) — a locked phone is a dealbreaker
- Install the eSIM over Wi-Fi and confirm it appears in your SIM list
- Label it something obvious like “Nomad Travel” so you don’t fumble between lines later
- Pre-set the toggles: you can enable Data Roaming on the Nomad line in advance — it does nothing until the line is active
- Screenshot your plan’s supported networks and APN from the Nomad app, so you have them even with zero connectivity
- Keep your home SIM on but with its data roaming OFF — you’ll still receive SMS verification codes without bill shock
The Bottom Line
A Nomad eSIM that won’t activate is almost never actually broken. Nine times out of ten it’s the installation-vs-activation confusion, a roaming toggle, or a network that needs manual selection. Work through the steps in order, restart after every change, and keep your hands off the delete button.
And if you’ve genuinely exhausted everything? Nomad’s chat support can see things you can’t — your eSIM’s provisioning status on their end — and can re-issue a faulty profile. Send them your order ID and settings screenshots, and you’ll usually be sorted within the hour.
Because it’s working correctly. Installation (adding the eSIM to your phone) and activation (connecting to a network) are separate steps. Your Nomad eSIM cannot finish activating until your phone reaches a supported local network at your destination. “Activating…” at home simply means no supported network is in range yet — it will complete automatically when you land.
Yes — it’s mandatory, not optional. Nomad eSIMs connect through partner networks abroad, which your phone treats as roaming. Without Data Roaming enabled on the Nomad line, the eSIM won’t pass data at all. And because Nomad plans are prepaid with a fixed data allowance, enabling roaming can’t generate surprise charges the way it can on your home carrier’s SIM.
Possibly not — this is the one error that can be permanent. Nomad warns that deleting an active eSIM may invalidate it, and QR codes are generally single-use, so rescanning the original code usually fails. Contact Nomad support immediately with your order ID; depending on the eSIM’s status, they may be able to issue a replacement profile. Don’t purchase a new plan until support confirms the old one is unrecoverable.
Signal without data usually points to one of three things: Nomad isn’t set as your data line, Data Roaming got toggled off, or the APN settings don’t match what your plan requires. Check all three — the correct APN is listed in the Nomad app under your plan details. If everything matches, restart the phone and try switching from 5G to LTE, which resolves compatibility hiccups on some partner networks.
Your phone is carrier-locked. A locked phone rejects all SIM profiles except its original carrier’s — Nomad included. Check Settings → General → About → Carrier Lock on iPhone; it must read “No SIM Restrictions.” If it names a carrier, contact that carrier to request an unlock (eligibility rules vary), then install your Nomad eSIM after the unlock completes.
Usually under five minutes once your phone connects to a supported network with the right settings. If it’s been more than 15 minutes after landing with the eSIM on, roaming enabled, and Nomad set as your data line, something needs a nudge — restart your phone first, then try manual network selection from the supported carrier list in the Nomad app.
It depends on the specific plan — Nomad sells both types. Most plans start their validity period upon activation (first connection to a supported network), but some begin from the purchase date. Check your plan’s details in the Nomad app before buying, especially if you’re purchasing more than a few days ahead of travel.
No — installation requires a stable internet connection (Wi-Fi or cellular) because your phone needs to download the eSIM profile from the carrier’s server. This is exactly why we recommend installing at home before your trip. Activation at your destination, on the other hand, doesn’t need pre-existing internet; it happens through the cellular connection itself.
