Signal but no internet on a HelloRoam eSIM starts with line settings

Short answer

To fix signal with no internet on a HelloRoam eSIM, check 4 line settings, restart, and wait 2 to 5 minutes. Turn the line on, pick it for mobile data, turn on data roaming, and turn off automatic data switching. Keep Wi-Fi and any VPN off while you test, or the test cannot show if the eSIM works.

Signal with no internet points to a line setting

What you seeWhat to do
The status bar shows 4G or 5G, but no page or app loads.Signal is not data. Check which line is picked for mobile data, and that roaming is on for the HelloRoam line.
Nothing loads, and Wi-Fi or a VPN is still switched on.Turn Wi-Fi off and turn any VPN off, then test again. Either one hides what the eSIM is doing. Google's Pixel help also says to turn Wi-Fi off to check you are on the mobile network.
The eSIM shows in your settings, but its line looks switched off.Turn the line on. Installed only means the eSIM is on the phone, not that it carries data.
One app fails while websites and other apps load fine.The eSIM has internet. Update that app, restart it or the phone, and check any VPN or content filter.
The line reads No Service, SOS or emergency calls only.The phone has not registered on a supported network yet. Work through the no-service guide instead of this one.

Once your eSIM connects, its QR code stops working

Your HelloRoam eSIM is in use from its first connection to a supported network in your destination. A line left on at home, or one that registers during a layover on a network your plan does not cover, does not count. After that, its QR code can't be used again, so never delete it. To check, open My eSIMs on the website. Active on the card, or Activated with an Activated On date in the details, means the eSIM is in use. Active can show a little before the first connection, so treat Active as in use. Ready or Not Activated is not proof that it has never connected, so never decide from those. The HelloRoam app shows no label for this, so don't use the app to decide. Its Install eSIM on this device button can stay visible after first use, and that is not proof you can install it again.

Still offline after every setting is on

  1. 1

    Check that you changed the HelloRoam line, not your home line. On iPhone and Pixel, each line has its own roaming switch, and it is easy to turn on the wrong one.

  2. 2

    Names like Primary or Secondary don't tell you which line is HelloRoam. Match the line's ICCID with the one in the HelloRoam app, then rename the line so it is obvious.

  3. 3

    In the app, tap More Detail on the eSIM's card, then About Your eSIM, to find the ICCID. It can show as N/A.

  4. 4

    Ignore the network name on screen. It can be the eSIM's own label rather than the name of the local network.

  5. 5

    Leave the APN settings alone. Don't add or edit them yourself. A name that looks odd on that screen does not mean it is wrong.

  6. 6

    If you have not reached your plan's destination yet, no data is normal. Test again after you arrive there.

  7. 7

    If data loads but crawls, run a speed test with Wi-Fi off, the HelloRoam line picked for mobile data and roaming on. Send us the result.

  8. 8

    If every check passes and data still doesn't load, it needs a technical check by support.

Settings to fix before anything else

  • Work through the settings checks above first. Deleting the eSIM is never a fix for a connection problem.
  • If the eSIM already shows in your settings, it is installed. Don't scan the QR code again, because the fix is in the settings.
  • Once your HelloRoam eSIM has connected, its QR code cannot install it again. Deleting it then loses it for good.
  • Only remove it and install it again with the same QR code or activation code if you know it has never connected. Connected means it reached a supported network in your destination. Put it back straight away, because an unused HelloRoam eSIM left off your phone does not stay available forever.

Send us these details about the line

If data still does not load after every check above, email help@helloroam.com. Screenshots of your settings tell us more than a description, so send what you can.

  • Your order number
  • Your phone make and model
  • The country and city you are in now
  • A screenshot of the HelloRoam line's settings showing the line, data roaming and the mobile data choice
  • On Samsung: screenshots of SIM manager and Mobile networks
  • A screenshot of the network selection screen
  • What you already tried: Wi-Fi off, VPN off, restart, and how long you waited
  • The exact error text, if you see one
  • If only one app fails: which app, and whether websites open

Questions about data that will not load

What is cellular data switching?

Cellular data switching lets your phone move mobile data to another line on its own. iPhone calls it Allow Cellular Data Switching, and Pixel calls it Automatic data switching. Apple says turning it on lets an iPhone use data from both plans, depending on coverage. Turn it off, and data stays on the HelloRoam line once you pick it. With it off, Apple notes that data stops during a call on your home line.

Why does my phone show 4G or 5G but I still have no internet?

A 4G or 5G icon only means your phone may be on a network. It does not show that data reaches the HelloRoam line. Check that the line is on and picked for mobile data. Then turn on data roaming for the HelloRoam line. The network name on screen can be the eSIM's own label, so it confirms nothing either.

How do I set my eSIM as the cellular data line on iPhone?

Open Settings > Cellular, tap Cellular Data, and choose the HelloRoam line. Then turn off Allow Cellular Data Switching on that screen, so data stays on the HelloRoam line. If the e-sim is not in that list, tap its line under Cellular and turn on Turn On This Line. Apple's help says only one line at a time can use cellular data, and it gives the same path for travel eSIMs.

Can a VPN stop my eSIM's data from working?

Yes. A VPN can stop pages from loading even when the HelloRoam line carries data. Apple's help also says to check for a VPN when a device has network problems. Turn it off before you test, or the result cannot show whether the e SIM works. A fair test needs Wi-Fi off, VPN off, the HelloRoam line chosen for mobile data and data roaming on.

Is No Service the same problem as having no internet?

No. No Service or SOS means the phone has not registered on a supported network yet. No internet with signal means it has, but data still fails. Start with the no-service guide for the first problem. Once the HelloRoam line shows a network, come back here for the data settings.
