eSIM installed but no internet?

Six causes, ranked by how often they are the real one. The first one is right about eight times out of ten.

If you have bars but nothing loads, the fix is almost always this: the travel eSIM is not selected as your data line, or Data Roaming is off for that line. A travel eSIM is a roaming profile — with roaming off it connects to the network and carries no data. You need both settings, not one.

What you see
What it actually is
The fix
Full signal bars, nothing loads
Data Roaming is off, or the wrong line is set to carry data
Settings > Cellular > Cellular Data > pick the travel eSIM. Then open that line and turn Data Roaming ON.
No signal at all on the eSIM line
The phone has not registered on a local network yet
Airplane mode on for 15 seconds, off again. If still nothing, restart the phone. Allow up to 5 minutes after landing.
QR code says invalid or will not scan
It has already been installed once — a QR code is single-use
Check Settings > Cellular for an extra line. If it is there, the eSIM is installed; the problem is elsewhere on this list.
“Cellular plan cannot be added”
The phone is locked to a carrier, or the model has no eSIM
Ask your home carrier to unlock it. Dial *#06# — no EID means no eSIM support.
It worked, then stopped
The allowance ran out, or the validity period ended
Open the pickup page from your order email to see remaining data. Buy another plan if it is empty.
Works on WiFi only
The eSIM is installed but not selected as the data line
Same fix as the first row — both steps, not one.

The exact settings path

iPhone

  1. Settings > Cellular > Cellular Data > select the travel eSIM (not your home line).
  2. Settings > Cellular > tap the travel eSIM > Data Roaming ON.
  3. Settings > Cellular > Cellular Data > Allow Cellular Data Switching OFF — otherwise the phone can slip back to your home line and bill you.
  4. Check your home line: tap it and make sure its own Data Roaming is OFF.

Android

  1. Settings > Network & internet > SIMs > select the travel eSIM.
  2. Turn Mobile data ON for it, and Roaming ON.
  3. Go back and open your home SIM, and turn its Roaming OFF.

Menu names shift a little between Samsung, Pixel and others, but the two switches are always called something close to "mobile data" and "roaming".

Still nothing? Do these in order

  1. Airplane mode on, wait 15 seconds, off. Wait a full minute.
  2. Restart the phone. This forces a fresh network registration and fixes a surprising share of cases.
  3. Settings > Cellular > the eSIM > Network Selection > turn Automatic off and pick a carrier from the list manually.
  4. Confirm you are actually at the destination. The plan does not activate until it connects there — it will look dead at home, and that is correct.

Common questions

My eSIM installed but there is no internet. What is wrong?

Almost always one of two settings. Either the travel eSIM is not the line selected for cellular data, or Data Roaming is switched off for that line. Both have to be right. A travel eSIM is a roaming profile by design, so with roaming off it registers on the network, shows bars, and carries no data at all.

On iPhone, what is “Allow Cellular Data Switching” and should I turn it off?

It lets the phone quietly fall back to your other line for data when the current one looks weak — which can mean your home SIM roaming at your carrier's rates without you noticing. Settings > Cellular > Cellular Data > Allow Cellular Data Switching, and turn it off while you travel.

How long should I wait after landing before worrying?

Five minutes. The phone has to find and register on a partner network, which is not instant, and airplane mode on and off usually speeds it up. If you still have nothing after a restart and five minutes, it is a settings problem, not a signal problem.

Can I reinstall the eSIM if I deleted it by mistake?

No. A QR code can only be installed once, and deleting a profile is permanent on most phones. That is why the install guide says not to delete the line until the trip is over. If it happened, email support@landedesim.com — an unused plan is refunded in full, and we will reissue where the supplier allows it.

Nothing on this page fixed it. Now what?

Email support@landedesim.com with your order email address. You get a replacement eSIM or a full refund — the promise on every order does not have a troubleshooting checklist attached to it.
