If your Halo eSIM shows “No Service” or “Searching” after you land at your destination, first turn off airplane mode (Control Centre on iPhone, the quick settings panel on Android) and give your phone up to five minutes to find a local network. Most connections establish within five minutes of landing. If it still shows No Service, work through these steps in order.
Quick checks
1. Find your eSIM line by its label
Your eSIM line will not be called Halo unless you named it that when you installed it. Look for it by the label it was given, and make sure it is turned on.
iPhone
Open Settings > Mobile Service (Mobile Data on older iOS). Your iPhone labels the line with whatever was picked at install: Secondary, Travel, or a custom label. Tap that line and confirm Turn On This Line is enabled.
Samsung
Open Settings > Connections > SIM manager. The eSIM is usually listed by its network name or as eSIM. Make sure it is toggled on.
Pixel/Android
Open Settings > Network and internet > SIMs. The eSIM is usually listed by its network name. Tap it and confirm Use SIM is toggled on.
2. Turn Data Roaming on for that line
Data roaming must be on for your eSIM line. This does not cause extra charges, because your plan already covers your destination. Leave data roaming off on your home line.
iPhone
Open Settings > Mobile Service (Mobile Data on older iOS). Tap your eSIM line. Turn on Data Roaming.
Samsung
Open Settings > Connections > SIM manager. Tap your eSIM. Turn on Data roaming.
Pixel/Android
Open Settings > Network and internet > SIMs. Tap your eSIM. Turn on Roaming.
3. If it is still offline, pick the network by hand
Your plan runs on a particular local network, and the phone does not always find it on its own. Your eSIM page (the Manage my eSIM link in your delivery email) names that network under Not connecting? Try this. If no network is named there, pick one from the list and give it a minute to connect.
iPhone
Open Settings > Mobile Service (Mobile Data on older iOS). Tap your eSIM line. Tap Network Selection. Turn off Automatic. Wait for the list of available networks to appear, then select your plan’s network.
Samsung
Open Settings > Connections > Mobile networks. Turn off Auto select. Select your plan’s network from the list.
Pixel/Android
Open Settings > Network and internet > SIMs. Tap your eSIM. Tap Preferred network type, then tap Choose network. Turn off Auto select and choose your plan’s network from the list.
4. Set your eSIM as your data line
Your device may still be using your primary SIM for mobile data.
iPhone
Open Settings > Mobile Service (Mobile Data on older iOS) > Mobile Data. Select your eSIM line. Turn off Allow Mobile Data Switching.
Samsung
Open Settings > Connections > SIM manager > Mobile data. Select your eSIM.
Pixel/Android
Open Settings > Network and internet > SIMs. Tap your eSIM and toggle Mobile data on.
5. Restart your device
Power your device off completely, wait 10 seconds, then power it back on. This forces your device to search for available networks and often resolves connection issues after landing.
6. Check your destination is covered
Open your order confirmation email and confirm the country you are in is included in your data plan. If you purchased a regional plan (e.g. Europe, Southeast Asia), check that your specific country is listed.
See Countries and regions covered by Halo eSIM for the full list.
