If your eSIM worked in one country but stopped in another, the cause is usually coverage limitations, roaming settings, network partner changes, or plan type — not that the eSIM suddenly broke.
This is very common with travel eSIMs. Many users move between countries expecting the same service everywhere, then suddenly see:
- No Service
- Emergency Calls Only
- signal but no internet
- worked yesterday, failed after border crossing
- slow speeds in new country
Most cases are easy to solve once you know the reason.
This guide explains exactly why your eSIM is not working in another country and how to fix it fast.
Quick answer: Check whether the new country is included in your plan, keep Data Roaming ON, restart the phone after crossing the border, and manually choose a supported local network.
1. The new country may not be included in your plan
This is the #1 reason.
Not all travel eSIMs are global. Many are:
- single-country plans
- regional plans
- limited multi-country plans
So a plan that works in France may not work in Switzerland, Serbia, Morocco, or Turkey unless specifically included.
Fix:
- Check your plan coverage list
- Upgrade or buy another plan if needed

2. Border crossing requires new network registration
After entering a new country, the phone must disconnect from the old network and register on a new partner carrier.
Fix:
- Wait 2–10 minutes
- Use Airplane mode ON/OFF
- Restart phone if needed
3. Data Roaming is OFF
Regional and multi-country eSIMs often rely on roaming agreements.
If roaming is OFF, the phone may fail in the second country.
Fix:
- Open eSIM settings
- Turn Data Roaming ON

4. Automatic network selection chose the wrong carrier
Your phone may connect to a visible network that is weak or unsupported for your plan in the new country.
Fix:
- Open Network Selection
- Turn Automatic OFF
- Try another available local network
5. APN settings need refresh
Sometimes internet worked in country A, but data routing fails in country B until APN refreshes.
Fix:
- Restart phone
- Recheck APN values
6. Plan validity expired during travel
It may look like the country caused the issue, but the real reason may be expiration.
Fix:
- Check validity days
- Check remaining data
7. Main SIM is interfering with data selection
On dual SIM phones, border changes sometimes make the phone switch data back to the main SIM.
Fix:
- Set eSIM as preferred data line
8. Coverage is weak in your exact location
Even supported countries can have poor local coverage in:
- mountains
- rural roads
- ferries
- border valleys
Fix:
- Move location
- Try outdoors

Leaving roaming OFF
Very common issue.
Not checking data SIM after crossing
Phones sometimes switch lines.
When to contact support
Contact support if:

Final thoughts
If your eSIM is not working in another country, the cause is usually plan coverage or network registration — not device failure.
Check the coverage list first, then restart, enable roaming, and manually select another carrier. Those steps solve many cross-border issues quickly.
