The 60-second answer
"Network not available" means your phone has an eSIM profile installed but has not registered on a carrier network with it. Nine times out of ten the profile is fine and one of four things is true: you are not in the plan's coverage country yet, the eSIM line is switched off, data roaming is off on that line, or the phone is stuck on a manual network selection. Work through the checks below in order — they are ordered by how often each one is the cause.

What the message actually means
Installing an eSIM writes a carrier profile onto your phone. Registering is a separate step that happens later, when the phone finds a partner network in range and the profile is accepted onto it. "Network not available", "No service", "Searching…" and "SOS only" are all the same underlying state: the profile exists, registration has not completed.
This is why the message is so common on landing. Your eSIM cannot register until the aircraft doors open and your phone sees a local tower — so an eSIM that looked fine when you installed it at home will read "no service" for the entire flight, and for a minute or two after airplane mode goes off.
- **SOS only** — the phone found a network but is not authorised on it. Emergency calls work; your data does not. Usually roaming or line settings.
- **No service / Network not available** — no usable network found for that profile at all. Usually coverage, a disabled line, or a stuck manual selection.
- **Searching…** — registration is in progress. Give it 2–3 minutes before doing anything.
Fix it in order
Do these in sequence and stop when data works. Each step is more disruptive than the last, so there is no benefit to jumping ahead.
Wait three minutes after landing
Turn airplane mode off and leave the phone alone for three minutes. First registration on a foreign network is genuinely slower than a home network — moving straight to the next step is the most common way people break a connection that was about to work.
Confirm the eSIM line is switched on
iPhone: Settings → Cellular → tap the travel eSIM → make sure "Turn On This Line" is green. Android: Settings → Network & Internet → SIMs → select the eSIM → toggle it on. A line that is installed but off shows exactly this error.
Turn on Data Roaming for the travel line
A travel eSIM is technically roaming on a partner network, so this must be on even though you are not roaming in the billing sense. iPhone: Settings → Cellular → tap the eSIM → Data Roaming → on. Android: SIMs → the eSIM → Roaming → on. Leave your home SIM's roaming OFF so it cannot bill you.
Set the travel eSIM as your data line
iPhone: Settings → Cellular → Cellular Data → select the travel eSIM. Installing a plan does not switch data over automatically, and a phone still pointed at your home SIM abroad will show no usable service on the travel line.
Reset network selection to Automatic
If you or a previous trip left manual selection on, the phone keeps hunting for a network that is not there. iPhone: Settings → Cellular → tap the eSIM → Network Selection → Automatic. Android: SIMs → the eSIM → Automatically select network → on.
Toggle airplane mode, then restart
Airplane mode on for 30 seconds, then off, forces a fresh registration attempt. If that does nothing, restart the phone fully — this re-reads the eSIM profile from scratch and clears a surprising number of stuck states.
Pick a network manually, once
As a diagnostic: switch Network Selection to Manual and see what appears. If local carriers are listed, the radio is working and the profile is being rejected — pick the carrier named in your plan details. If nothing is listed, you have a coverage or hardware problem, not a plan problem. Set it back to Automatic afterwards.
Check the APN as a last resort
Most eSIMs configure this automatically. Only if everything above fails, follow the APN steps in our eSIM not working guide using the APN printed in your activation email.
If none of that worked
At this point the problem is not a setting. Three real possibilities remain, and they are distinguishable.
| Symptom | What it means | What to do |
|---|---|---|
| Manual search lists no carriers at all | The radio is not seeing any network — genuine dead spot, or a hardware/lock issue | Move outdoors or to another area and retry before assuming a fault |
| Carriers are listed but every one is rejected | The profile is not authorised on those networks — usually a plan that has not started or has expired | Check your plan status and validity dates, then contact support |
| Your home SIM works but the eSIM never does | The phone is carrier-locked, so it refuses third-party profiles | iPhone: Settings → General → About → Carrier Lock should read "No SIM restrictions" |
| It worked, then stopped mid-trip | Data allowance exhausted, or validity ran out | Check remaining data; top up or buy a new plan |
If you bought from us and are still stuck after the steps above, contact us with your ICCID and the exact wording on your screen. We can see whether the profile ever registered, which immediately separates a plan problem from a phone problem.
How to avoid it on the next trip
- Install the eSIM at home over Wi-Fi, but expect "no service" until you land — that is normal and not a reason to reinstall.
- Set the data line and turn on Data Roaming for the travel line *before* you fly, while you still have working internet to look things up.
- Turn Data Roaming OFF on your home SIM at the same time, so it cannot quietly bill you.
- Screenshot your activation email, including the APN and ICCID, so you have it offline.
- Check your phone is carrier-unlocked before departure, not at the gate. See eSIM compatible phones.
Frequently asked questions
Why does my eSIM say "no service" before I travel?
Because a country-specific travel eSIM has no network to register on until you are in that country. Seeing "no service" at home is expected and does not mean the eSIM failed to install. Check that the profile appears in your cellular settings — that is the only thing that needs to be true before you fly.
How long should I wait after landing before something is wrong?
Three minutes with airplane mode off. First registration on a foreign network is slower than you are used to. If you still have nothing after three minutes, start at step 2 of the sequence above.
What is the difference between "SOS only" and "No service"?
"SOS only" means the phone found a network but is not authorised to use it for anything except emergency calls — usually a roaming or line-settings problem. "No service" means it found nothing usable at all — usually coverage, a disabled line, or a stuck manual network selection.
Do I need data roaming on for a travel eSIM?
Yes. A travel eSIM connects as a roaming guest on a local partner network, so Data Roaming must be enabled on that line. It does not cost extra — the plan is prepaid. Keep Data Roaming off on your home SIM so that one cannot charge you.
Will reinstalling the eSIM fix it?
Almost never, and it can make things worse: most QR codes are single-use, so deleting a working profile can leave you with nothing until support re-issues it. Exhaust the settings checks first, and contact support before deleting anything.
