eSIM shows connected but no internet: the 5 usual suspects
Key facts
- "Connected but no internet" is nearly always a settings issue: mobile data on the wrong line, or roaming off on the eSIM line.
- Data roaming must be ON for the travel eSIM and OFF for your home SIM.
- Airplane mode on/off, a restart, or manual network selection clears most stuck registrations.
- The free eSIM Rescue tool at voasim.com/sos diagnoses an eSIM of any brand, not just VoaSim's.
- VoaSim charges one price per duration for every destination, from USD 18.90 for 5 days to USD 106.90 for 60 days, with truly unlimited data.
Want us to confirm it for your case?
You land, the eSIM grabs a network, the signal bars look fine — and nothing loads. It is one of the most common travel-day panics, and in most cases it is a two-tap fix inside your phone settings.
Below are the five usual suspects, in the order you should check them. Work through them from top to bottom instead of jumping around, because each step rules out a cause.
Check 1: is mobile data actually assigned to the eSIM?
This is the number one cause. Your phone now has two lines: your physical SIM and the travel eSIM. Signal bars can come from the eSIM while mobile data is still pointed at your home carrier line — which is roaming-blocked, so nothing loads.
- iPhone: Settings → Mobile Service (Cellular) → Mobile Data → select the travel eSIM line.
- Android: Settings → Network & internet → SIMs → pick the eSIM → set it as the mobile data SIM.
While you are there, turn off data roaming on your home line so your carrier cannot bill you. Your number and WhatsApp keep working over the eSIM's data connection — you are not losing your number.
Reload a page after the switch. If it works, you are done. If not, move to check 2.
Check 2: data roaming must be ON for the eSIM line
It sounds backwards, but a travel eSIM connects to local partner networks, and the phone treats that as roaming. If data roaming is off on the eSIM line, you get registration (bars) with zero data.
- iPhone: Settings → Mobile Service → tap the eSIM line → Data Roaming → on.
- Android: Settings → Network & internet → SIMs → eSIM → Roaming → on.
Confirm you toggled roaming on the eSIM, not on your home SIM. Both lines have their own switch and they look identical in the menu. Turning it on for the wrong line is how people end up with an unexpected roaming bill and still no internet.
Give it 30 seconds to re-register. Still nothing? Next suspect.
Check 3: the APN
The APN is the address your phone uses to open a data session. Most eSIMs configure it automatically, but a leftover APN from your home carrier or a failed auto-setup will produce exactly this symptom: connected, no internet.
Look for the APN value in your eSIM activation email or installation guide and enter it manually:
- iPhone: Settings → Mobile Service → eSIM line → Mobile Data Network → APN field.
- Android: Settings → Network & internet → SIMs → eSIM → Access Point Names → add or edit.
Type it exactly as provided — no capitals, no trailing space. Save, then restart the phone. If your plan's instructions say the APN is automatic and the field is blank, leave it blank; a wrong manual APN blocks data just as effectively as a missing one. Full install steps live in our guides.
Check 4: airplane mode, restart and manual network selection
A bad network registration sticks until you force the phone to redo it. Two fast resets:
- Airplane mode on, wait 30 seconds, airplane mode off.
- Full power off and on. Slower, but it clears more.
If it still fails, choose the network by hand. Go to network selection, turn off automatic, and pick a different local operator from the list. Some partner networks in a country carry data better than others at a given moment, and your phone does not always pick the best one on its own.
Also worth ruling out: an active VPN, a content blocker, or Low Data Mode. Turn them off and test again. And check you are not still inside the plane or a deep basement — an eSIM works on land and at ports, but not at sea on a cruise.
Check 5: the plan, the dates and the device
Last, confirm the boring stuff. Has the plan actually started? With VoaSim, days start counting at the eSIM's first connection to a network at the destination — so installing at home is safe, but the clock does start when you land and switch the line on. Check you are not past the end date, and that you are in a covered destination: VoaSim reaches 170 destinations, but not the island Caribbean (Puerto Rico works, on US networks).
Device side: dial *#06#. If an EID appears, the phone supports eSIM. Carrier-locked phones must be unlocked first — a locked handset can register and still refuse data. Compatible from iPhone XR, Galaxy S20, Pixel 3 and most phones released from 2020 on. See the full list on our eSIM page.
