If your eSIM is not working after disabling Automatic Network Selection, the most common reasons are choosing the wrong carrier, locking onto a weak network, unsupported roaming partner selection, stale registration, slow data on a poor network, or users not realizing travel eSIM plans often depend on automatic carrier switching.
This commonly happens when travelers manually choose a network to chase stronger signal or faster speeds.
Then they suddenly notice:
- No Service
- bars but no internet
- very slow data
- network keeps dropping
- eSIM seems broken
The good news: in many cases, your eSIM is working normally. The issue is the manually selected network.
Quick answer: Turn Automatic Network Selection back ON, refresh the connection, and let the phone choose the best supported roaming partner.
1. Wrong Carrier Was Selected
This is the #1 reason.
Some visible networks are not included in your eSIM provider’s roaming agreements.
Fix:
- Enable Automatic Network Selection
2. You Locked Onto a Weak Network
A manually chosen network may show bars but perform poorly.
Fix:
- Switch back to Automatic
- Try another area
3. Roaming Partner Changed by Region
Travel eSIM providers may use different partners across cities or borders.
Fix:
- Use Automatic selection for dynamic switching
4. Data Roaming Is OFF
Manual network changes may hide the real issue.
Fix:
- Select the eSIM
- Turn Data Roaming ON
