eSIM not working? Here's the fix.
Deep breath — it's almost always one toggle. Five steps, in order, and you'll be online before the luggage belt starts.
The 5-step fix, in order.
1Turn the eSIM line on — and give it a minuteSettings → Mobile/Cellular Data → select your travel eSIM line → toggle it on. First attach on a new network can take 60–90 seconds, especially straight off the plane while thousands of phones reconnect at once.
2Data Roaming ON — for the eSIM line onlyThis is the one that catches almost everyone: travel eSIMs attach to partner networks, and your phone files that under "roaming". Roaming ON for the travel eSIM is correct and safe — the price was fixed when you bought it. (Keep it OFF for your home SIM.)
3Set the eSIM as your data lineYour phone may still be routing data through your home SIM. Settings → Mobile/Cellular Data → "Mobile Data" (iPhone) or "Preferred SIM for data" (Android) → choose the travel eSIM.
4Select a network manuallyIf it still shows no service: Settings → your eSIM line → Network Selection → turn off Automatic and pick a network from the list. If the first refuses to attach, try the next — partner agreements vary by network.
5Restart the phoneThe oldest advice in telecoms because it works: a restart forces a fresh network registration. Do this after the settings above, not instead of them.
Device-specific settings.
The same five steps live in slightly different menus on each brand — here's exactly where.
iPhone.
- Settings → Mobile Data → check the eSIM line is On and selected under "Mobile Data".
- Data Roaming lives per-line: Mobile Data → your eSIM → Data Roaming → On.
- If the eSIM installed but shows "No Service": Network Selection → disable Automatic.
- iOS 17.4+ one-tap installs: if you tapped the install button abroad and it stalled, finish on any Wi-Fi — installation needs a connection.
Samsung Galaxy.
- Settings → Connections → SIM manager → confirm the eSIM is On and set as "Mobile data" SIM.
- Settings → Connections → Mobile networks → Data roaming → On for the eSIM.
- APN rarely needs changing — but if data still fails, Mobile networks → Access Point Names → reset to default.
- One UI hides new eSIMs occasionally: restart after install if the line doesn't appear.
Google Pixel.
- Settings → Network & internet → SIMs → select the eSIM → toggle "Use SIM" On.
- Same screen: turn on Roaming, and set "Mobile data" to the travel eSIM.
- If the download stalled during install: SIMs → "+ Add more" won't duplicate a purchased eSIM — contact us instead of re-scanning a used QR.

Install the eSIM on home Wi-Fi the evening before you fly — your plan days don't start until it first connects abroad, so installing early costs nothing. Label the line clearly, set the roaming toggle then and there, and landing becomes the boring part. Our install guide walks it through in two minutes.

Nine times out of ten: Data Roaming is off for the eSIM line, or your phone is still using the home SIM for data. Turn roaming ON for the travel eSIM only and select it as the data line — that resolves most "no internet" cases in under a minute.
