No signal on your eSIM means it has not joined a network yet
No Service or SOS on your HelloRoam eSIM means it has not joined a supported network yet. Check that the line is on, data roaming is on, and it is your mobile data line. Then run one manual network scan and give each network 2 to 5 minutes. If none connects, email the list and your location to help@helloroam.com.
What SOS, No Service and a slow 3G signal mean
| What you see | What to do |
|---|---|
| No Service, Searching or no network name at all on the HelloRoam line | Turn the line on, turn data roaming on for it, and set it as your mobile data line. |
| SOS, or emergency calls only | Your phone has not registered on a supported network yet. Run the manual network scan for your phone below. |
| An E or 3G icon, and pages crawl | You are on a network, just a slow one. Test with Wi-Fi off and note the signal type. |
| 4G or 5G showing, but no page will load | This is not a signal problem. Our no-internet guide covers it. |
| A network name you do not recognize on the HelloRoam line | That can be the eSIM's own label, not the local operator. Judge it by whether data loads. |
Run a manual network scan on your phone
iPhone
An iPhone keeps the line settings under Settings > Cellular. The scan below is a test, not a new setting to keep. Once a network connects, turn automatic network selection back on, so your phone can change networks as you move.
Open Settings > Cellular and tap the HelloRoam line.
Turn Wi-Fi off and switch off any VPN before you test.
ClipOpen the line's network selection setting.
Turn the automatic option off.
Wait for the full list of networks to appear.
Screenshot the whole list before you tap anything on it.
Tap one network and wait 2 to 5 minutes.
If it does not connect, go back and try the next one.
Illustration

Samsung
Galaxy phones keep the line settings under Settings > Connections > SIM manager. Samsung lists No signal and Roaming as different status bar icons, so a Roaming icon alone does not mean no service. If Select automatically turns itself back on mid-scan, or the list stays empty, restart the phone and try again. The scan is a test, not a setting to keep: once a network connects, turn Select automatically back on, as Samsung advises.
Open Settings > Connections > Mobile networks.
Turn Wi-Fi off and switch off any VPN.
Go back to Mobile networks and tap Network operators.
Turn Select automatically off.
Wait for the scan to finish listing every network it finds.
Screenshot the full list before you pick anything.
Pick one network and wait 2 to 5 minutes.
If it does not connect, go back and try the next one.
Illustration
Pixel
Pixel keeps the line settings under Settings > Network & internet > SIMs. If Automatically select network turns itself back on mid-scan, or the list stays empty, restart the phone and scan again. The scan below is a test, not a new setting to keep. Once a network connects, turn Automatically select network back on, the normal setting for your HelloRoam line.
Open Settings > Network & internet > SIMs.
Tap the HelloRoam line.
Turn Wi-Fi off and switch off any VPN.
Back on the HelloRoam line, turn off Automatically select network.
Wait for the full list of networks to load.
Screenshot the list before you choose a network.
Choose one network and give it 2 to 5 minutes.
If it does not connect, come back and try another one.

Other Android
Menu names change from brand to brand, so look for the wording closest to each step. If Automatically select network turns itself back on mid-scan, or the list stays empty, restart the phone and scan again. The scan is a test, not a new setting to keep. Once a network connects, turn Automatically select network back on.
Open Settings > Network & internet > SIMs, or Mobile network on older phones.
Turn Wi-Fi off and switch off any VPN.
Open the HelloRoam line and find Automatically select network.
Turn Automatically select network off.
Wait for the scan to finish before you read the list.
Screenshot the full list before you tap a network.
Tap one network and wait 2 to 5 minutes.
If it does not connect, go back and try the next one.

When no network answers at all
- 1
Check the destination on your order. A country plan covers one destination, while regional and global plans cover a set list, and outside that there is no supported network to join.
- 2
On a phone with two lines, check that the settings and network list you opened belong to the HelloRoam line, not your home line.
- 3
With more than one eSIM installed, match the ICCID first so you test the right line.
- 4
On a Galaxy phone, open Mobile networks > Network mode. On other Android phones, look for Preferred network type. Pick the option that includes 5G or LTE.
- 5
After any network change, restart the phone, keep Wi-Fi off and wait 2 to 5 minutes before you judge it.
- 6
If the line shows E or 3G rather than nothing, you are connected on a slow network. Test with Wi-Fi off and data roaming on, run a speed test, then note the signal type and the network name.
- 7
When nothing on the list connects, or the list stays empty after a restart, stop testing and write in with the screenshot and where you are.
Leave the APN settings alone and do not reset network settings. Do not delete the eSIM and do not scan its QR code again, because a network problem never calls for either.
The details support needs to trace a network
When the checks and the scan change nothing, email help@helloroam.com. Send these details in the first message so nobody has to ask you for them.
- Your order number.
- Your phone make and model.
- The country and city you are in right now.
- A map screenshot zoomed out far enough to show the area around you, especially near a border, on an island or at a port.
- A screenshot of the full network list from the scan, taken before you picked anything.
- Which networks you tried, and what happened after each one.
- What the line shows now: No Service, Searching, SOS, emergency calls only, E, 3G, 4G or 5G, plus the network name on screen.
- If service is slow rather than missing: a speed test result taken with Wi-Fi off.
- A screenshot of the HelloRoam line's settings showing the line on, data roaming on and the mobile data choice.
- Whether Wi-Fi and any VPN were off while you tested, and whether you restarted the phone.
- Your phone's software version, if we ask for it.
- If you have more than one eSIM on the phone: the ICCID shown for the HelloRoam line.
Crop any QR code out of your screenshots before you send them.
help@helloroam.comSignal and network questions
Why does my eSIM say no signal?
Your HelloRoam e SIM shows no signal because it has not joined a supported network yet. Check 3 settings first: the line is on, data roaming is on, and it is your mobile data line. Then run one manual network scan. During a call on your home line, an iPhone can show No Service on the HelloRoam line, as Apple explains. There is a separate fix if signal shows but nothing loads.
What does 'Turn On This Line' mean on my iPhone?
Turn On This Line is the switch that powers the HelloRoam line itself, before any network setting matters. Find it under Settings > Cellular after you tap the line. If that switch is off, the line cannot register anywhere, and no amount of scanning will help. Check it first, then check data roaming for the same line.
Why is my eSIM signal so weak?
A weak eSIM signal means your HelloRoam line found a network, but only a poor or slow one where you stand. The line is still connected when it shows few bars or an E or 3G icon. Your exact spot matters, especially near a border, on an island or at an airport. Move a short way, as Google advises, and test again with Wi-Fi off. If it stays slow, try another network from the manual scan.
Why does my phone say SOS only?
SOS only means your phone is not connected to your cellular network, Apple explains. On a HelloRoam eSIM, SOS or emergency calls only means the line has not joined a supported network yet. It is a network problem, not a bad install, so do not delete the eSIM or scan its QR code again. Check the line settings, then run one manual network scan and give each network 2 to 5 minutes.
Is it normal for my eSIM to show the wrong network name?
Yes. Your HelloRoam line can show HelloRoam as its network name, or the name of a local partner network. The HelloRoam name is the eSIM's own label, not proof of which network your e-sim joined. Judge the line by whether data loads. See what to check if you may be outside your plan's destination.
