If your eSIM-Now data isn't working on your iPhone, don't worry — the large majority of cases are a quick settings fix, not a faulty eSIM. Work through the checks below in order and you'll be back online in a couple of minutes.
First — are you actually at your destination yet?
Travel eSIMs connect to a local network only when you arrive. Seeing "No Service" or "Searching…" while you're still at home, in the air, or in transit is completely normal — it's not broken. Give it a few minutes after you land (with Airplane Mode off). And whatever you do, don't delete the eSIM to "retry" — most travel eSIMs can't be reinstalled once removed.
The 60-second checklist
Nine times out of ten, it's one of these:
Fix it step by step
Confirm the eSIM is installed
Go to Settings → Cellular and look under SIMs. You should see your eSIM-Now line listed.
Not there? It never finished installing. Reinstall it from the QR code or activation link on your profile page — over stable Wi-Fi. If install fails with an error, jump to common error messages below.
Turn the line on & make it your data line
Tap your eSIM-Now line and check Turn On This Line = ON.
Then go to Settings → Cellular → Cellular Data and select eSIM-Now. Switch Allow Cellular Data Switching = OFF so your iPhone can't quietly fall back to your home SIM.
Turn Data Roaming ON — the #1 fix
On your eSIM-Now line, set Data Roaming = ON. Travel eSIMs connect through local partner networks, which counts as roaming — without it you'll have no data even with full bars. This single setting resolves most "not working" cases.
Restart, then toggle Airplane Mode
Restart your iPhone (off, wait 30 seconds, on) and give it two minutes. A surprising number of issues clear here.
Then toggle Airplane Mode on for 30 seconds and off — this forces your iPhone to re-register on the local network.
Pick a network manually
This is the step most people never try — and it fixes a lot of "No Service / SOS Only". Go to Settings → Cellular → eSIM-Now → Network Selection and turn Automatic = OFF. Wait for the list, then tap a different carrier.
If one partner network won't connect, another usually will. (Only works once you're at your destination.)
Confirm it's actually working
Turn Wi-Fi fully OFF (Settings → Wi-Fi → off) and open Safari. If pages load, your eSIM is working.
Still unsure? Settings → Cellular and scroll to the usage figures. If eSIM-Now's data usage is climbing, it's connected. If it's stuck at zero, your iPhone isn't using the eSIM for data — recheck Steps 2–3.
Decode your status bar
✅ You're connected
⚠️ Needs attention
If you see anything in the right-hand column after you've arrived, work through Steps 3–5 above (Data Roaming, restart, manual network selection).
Common error messages
Likely cause: weak Wi-Fi during install, the QR code was already used, the iPhone is carrier-locked, or a temporary Apple activation hiccup.
Fix: restart and try again on stable Wi-Fi. Confirm your iPhone is unlocked (Settings → General → About → look for "No SIM restrictions"). Each QR code works once — if it's already installed, don't rescan; find it on your profile page.
Likely cause: Data Roaming off, wrong network selected, you haven't arrived yet, or a temporary outage.
Fix: if you're at your destination, turn Data Roaming ON (Step 3), then try manual network selection (Step 5). Before arrival, this is normal.
Likely cause: your iPhone reaches a network for emergency calls but can't register for data — usually no partner network selected.
Fix: manual network selection (Step 5) almost always resolves this. Restart afterwards.
Likely cause: the iPhone can't register on a network — wrong network, temporary carrier issue, or you're not at the destination yet.
Fix: restart, then pick a network manually (Step 5). Give it up to two minutes to reconnect.
Internet works, but it's slow
Service is fine but pages crawl? This is almost always temporary local congestion, not your eSIM. Try, in order:
- Toggle Airplane Mode on and off
- Switch networks manually (Step 5) — a less-busy partner network is often much faster
- Move outdoors or to a different spot — walls and crowds kill mobile speeds
- Disable any VPN you have running
- Restart your iPhone
Last resort: Reset Network Settings
If nothing above works, reset your network settings: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
This clears saved Wi-Fi passwords and cellular settings — but it will not delete your eSIM. Your eSIM-Now line stays installed.

Having these ready in your first message means we can usually pinpoint the issue in one reply — no back-and-forth:
Good to know
- eSIM-Now plans are data-only — no phone number, so no regular calls or SMS/OTP codes. Keep your home SIM for those, and use WhatsApp or FaceTime over data.
- Data Roaming must be ON for travel eSIMs — this is normal and expected, not extra charges from us.
- Removing an eSIM is permanent — most travel eSIMs can't be reinstalled. Keep yours installed until your trip is over.
