eSIM Installed but No Signal? Work Through These 8 Steps
You land, switch the phone on, and the status bar says No Service. This is the single most common message our support line gets. The reassuring part first: an eSIM that installs fine but shows no signal is almost never a faulty profile. It is a switch on your handset that is still off.
The eight steps below are ordered by how often each one turns out to be the culprit. Work through them in order and glance at the signal bars after each one — do not skip around.
eSIM no signal: the 8 steps, in order
Three causes of an eSIM with no signal — find your symptom
| What you see | Most likely cause | Which step |
|---|---|---|
| No Service, no bars at all | Line not enabled, or still latched to the old network | Steps 1, 4, 5 |
| Bars showing but nothing loads | Data roaming is off (by far the most common) | Step 3 |
| Connects but crawls, stuck on 3G | Attached to a weak partner network, or APN wrong | Steps 5, 7 |
| Error during installation, never installed | Not a signal problem — install failure | See further reading below |
| Worked fine, then died | Line switched off by an OS update, or a temporary cell issue | Steps 4, 6 |
The row worth memorising is the second one. Having bars and having data are two different things. Seeing bars, assuming the eSIM is fine and blaming the plan is the most common misdiagnosis there is.
Where iPhone and Android differ
- ✅ iPhone (iOS 26) asks whether the profile is "Data Only" or "Voice & Data" during setup. For a data-only travel eSIM either choice works, and if you pick the wrong one you do not need to reinstall — change it under Cellular.
- ✅ iPhone dual SIM: the classic mix-up is between Cellular Data and Default Voice Line. The one you need to change is Cellular Data; leaving voice on your home number is fine.
- ✅ Android menu locations vary a lot by brand. Samsung puts it under Connections → SIM manager, Pixel under Network & internet → SIMs. If you cannot find it, search "SIM" in Settings.
- ✅ The Android roaming toggle is usually two levels deep — you only see it after tapping into that specific SIM, not on the outer mobile network page.
When it is not your handset
Two situations will never resolve no matter how much you troubleshoot:
- ⚠️ A Thailand plan installed before departure. Thai eSIMs have to be installed after you land, over airport wifi. Installing early invalidates the profile. This is specific to Thailand and the opposite of how Japan and Korea work.
- ⚠️ A carrier-locked handset. Contract phones and some second-hand phones are locked; no SIM from anyone will work until the original carrier unlocks it.

What our refund actually means
If you have done all eight steps and it still will not connect, message us rather than burning time abroad. Our test is simple: unless the handset is carrier-locked or the plan has already been used normally, we refund. An extra hour lost overseas costs you far more than the plan does.
eSIM no-signal FAQ
I have signal bars but no internet. What is it?
Nine times out of ten, data roaming is off. A travel eSIM attaches to a local partner network as a roaming subscriber, so with roaming disabled you get bars and nothing else. Make sure you enable it on the eSIM line, not your home line.
How long should it take to connect after landing?
Normally one to three minutes after you switch airplane mode off. If nothing has happened after five minutes, redo step 1 and select a carrier manually. Some delay is normal — an entire arriving terminal is competing for the same cells.
Can I just delete the eSIM and reinstall it?
Don’t, not casually. Most QR codes can only be installed once, and deleting the profile does not guarantee you can download it again. Ask us first and we will confirm whether your plan supports reinstallation.
How do I know my phone supports eSIM at all?
Dial *#06#. If an EID appears, it does. If you are unsure, our compatibility checker gives you the exact settings path for your brand.
Something is wrong with my Peanutmo plan. Who do I contact?
Message LINE at @peanutmo / WhatsApp +886-921-963-203 with the three screenshots (status bar, cellular settings, *#06# result). One exchange is usually enough to diagnose it. If it turns out to be the plan, we refund — we will not send you off to argue with a local carrier.
Does everyone in the group need their own eSIM, or can we hotspot?
Most plans allow hotspotting, though it varies by handset and plan and we cannot promise every combination works. In practice one eSIM per phone is the better setup: hotspotting drains the battery fast, and whoever gets separated from the group is the one left with no data.
