No signal after landing
Check four things in order: is the eSIM line switched on; is mobile data set to the eSIM line; is data roaming enabled for that line; and if all three are set, use manual network selection and pick one of the partner networks listed on your plan page. These four cover almost every case.
The plane touches down, airplane mode comes off, and the screen just sits there with an empty signal bar or the words No Service. It is an alarming moment, and the instinct is to assume the eSIM itself is broken or the wrong plan was bought. In the large majority of cases we see, though, the cause is not a faulty profile at all — it is one of a handful of settings on the phone that has not been finished, and there are four points worth checking in order before concluding anything is actually wrong.
This page is for anyone who has just landed and is staring at a dead signal, anyone who wants to work through the checks themselves before spending time reaching out to someone, and anyone who wants to understand why the checks need to happen in this particular order. We will go point by point, starting with whether the line is switched on at all, through to manual network selection, and then cover what to do once all four checks are done and the signal still is not there — without guessing at a specific carrier name or a fixed menu path, since those differ by phone maker and by operating-system version.
Check one: is the eSIM line switched on
A phone that supports more than one active line at once shows a list of lines inside the mobile network settings, and each one carries its own on/off switch that is entirely separate from the airplane-mode switch. It is entirely possible that during travel the eSIM line got switched off without anyone meaning to — for instance, some phones default a freshly installed profile to off until it is turned on manually, or the switch was tapped by accident while cycling airplane mode on and off a few times.
The check is to open the phone lines or plans menu in settings and see whether the line belonging to the eSIM shows as enabled. If it is off, turn it on, then wait briefly for the phone to search for a network. This should always be the first thing tried, because if the line itself is switched off, no other setting being correct will bring a signal back.
Check two: is mobile data set to the eSIM line
Turning the line on is not the whole story. A phone with two active lines carries a separate setting for which line handles mobile data, and some phones leave that pointed at the home line or whichever line was in use before travel, even with the eSIM line switched on. The result is calls working normally while nothing loads on data at all, because the phone is still trying to pull data through a line that has no service abroad.
This is a straightforward fix: open mobile data settings and set the eSIM line as the one used for data. Some phones offer an automatic data-switching option that falls back to the other line when the primary one has no service — it is worth turning that off while travelling, since it can silently switch data back to the home line and rack up charges nobody intended.
Check three: is data roaming enabled for the eSIM line
Even with the line on and data pointed at it correctly, many phones still require a separate data-roaming switch to be turned on for that specific line. It usually sits on the same page as mobile data settings, though on some phones it is tucked further down inside that line's own submenu. With this switch off, the phone can see a foreign network but refuses to use data through it, treating it as roaming that has not been authorised.
Check four: select the network manually and pick a partner network
If the first three checks are all done and there is still no signal, open the eSIM line's carrier selection settings and turn off automatic network search, letting the phone list the networks it detects in that area instead. Then choose the one that matches a partner network named on your own plan's details page.
The reason for choosing manually is that the phone sometimes latches onto a network that is not a partner of the plan, on its own, and that network name shows on screen while data simply does not work, because it falls outside that plan's roaming arrangement. Selecting manually forces the phone to switch to the correct one instead.
Where the partner network list lives
The partner network list for each plan lives directly on that plan's own details page, not in one shared list that applies to every plan, because roaming arrangements differ by country and by provider. It is worth opening it before travelling and noting the names down, so there is no guessing while stuck without signal partway through a trip.
Why these four checks need to happen in this order
These four are ordered from the setting with the broadest effect to the narrowest. A switched-off line makes everything after it meaningless, while manual network selection is the most specific of the four and should be tried last, since if the first three are not set correctly, choosing a network manually will not fix anything on its own.
Working through them in order also saves time. Rather than randomly flipping settings back and forth without a system, checking one at a time makes it clear exactly which point is the real cause, and there is no need to go back and recheck a point that has already been cleared.
A systematic order to work through
- 1Turn the eSIM line on in the phone lines menuOpen mobile network settings, look at the list of lines, and switch the eSIM line to enabled if it is currently off.
- 2Set mobile data to the eSIM lineOpen mobile data settings, choose the eSIM line as the primary data line, and turn off automatic data switching if the phone offers it.
- 3Turn on data roaming for the eSIM lineGo to that specific line's own roaming switch, and confirm the line's name before turning it on.
- 4Select the network manuallyTurn off automatic network search and choose the network that matches a partner name on the plan's details page.
- 5Restart the phone if signal still has not appearedIf all four are done and a couple of minutes have passed with no signal, try restarting the phone once.
Menus differ by phone maker and OS version
The exact menu names and the position of each switch vary by phone maker and by operating-system version. Some versions group the roaming switch on the same page as mobile data, others tuck it into a submenu specific to each line. We do not name a fixed menu path on this page, because it would easily be wrong compared with the actual phone in your hand.
Summary table: what the signal indicator is telling you
| What shows on screen | Likely meaning |
|---|---|
| Shows No Service or no bars at all | The line may be switched off, or it has not attached to any network yet — start from check one |
| Shows SOS or SOS only | The phone sees an emergency-only network but has not attached to a partner network; try manual selection |
| Full signal bars but no data icon | Voice signal works but data roaming or the data line setting may still be off — check two and three |
| Data icon shows but nothing loads | May be attached to a network that is not a plan partner; try selecting a network manually again |
If all four checks are done and there is still no signal
This is far less common, but a few possibilities remain: the phone may not be fully unlocked from a previous carrier, limiting how another eSIM can be used, or a physical SIM may still be set as the primary line for some functions in a way that quietly blocks the eSIM, or the eSIM profile may not have installed completely in the first place and needs removing and installing again.
Check device compatibility before the next trip
If the root cause is that the phone does not fully support eSIM, or is still locked to a previous carrier, the four checks above will only go so far. The better approach is checking device compatibility ahead of the next trip, rather than troubleshooting mid-journey.
Just installed the profile and never connected yet
If this is the first time using this eSIM and no signal has ever appeared, even at home before travelling, it is worth going back and reviewing the installation steps first, since in some cases the issue is an incomplete installation from the start, not the four settings covered on this page.
Second summary table: symptom and what to try next
| Symptom | What to try next |
|---|---|
| Never had signal since installing | Review the installation steps again; it may not have completed properly the first time |
| Had signal at home but it disappeared after landing | Work through the four checks on this page in order |
| All four checks done, waited, restarted, still no signal | Confirm the phone is unlocked and fully eSIM-capable, then reach out to support |
A checklist for before leaving the airport
- The eSIM line shows enabled in the lines menu
- Mobile data points to the eSIM line, not the home line
- Data roaming is on for the eSIM line specifically
- Automatic network search is off and a partner network is selected manually
- The partner network names from the plan page are noted down before departure
- Automatic data-switching between lines is turned off
- The settings search box's location is known, in case a switch cannot be found by browsing
When it is worth contacting support
If all four checks are done, the phone has been restarted, and device compatibility has been confirmed not to be the cause, yet there is still no signal, it is worth contacting support with the details of what has already been tried, so the profile side can be checked more precisely. The channels available are LINE chat, email, and phone at 089-942-0818 / 088-521-6848 — we take messages around the clock, every day.
Vanliga frågor
How long should I wait after turning off airplane mode before starting the four checks+
Give the phone about one to two minutes to search for a network on its own first. If there is still no signal after that, start working through the checks on this page in order.
Why can I make calls but not use data+
A data-only eSIM normally has no calling function of its own. If calls are working, that is likely your original line, not the eSIM line — check that mobile data is actually pointed at the eSIM line as covered in check two.
I selected manually and none of the partner networks appear in the list at all+
Try moving to a spot with better signal, such as near a window or outdoors, then search for networks again. If a partner network still does not appear, contact support with the country and the plan you are using.
Do I need to turn my original line off completely while using the eSIM+
No. If the phone supports two active lines at once, you can leave your original line on to still receive calls and texts normally — just turn off that line's data roaming and set mobile data to the eSIM line instead.
The phone shows it is attached to a network but not a single webpage loads+
Check whether the attached network matches a name on the plan's partner list. If it does not, select a network manually again and choose one that does match that list instead.
