You’ve installed your eSIM, you’re ready to get online… and then—no signal, no data, or activation errors. Annoying? Yes. Unfixable? Absolutely not. Here’s the truth: 99% of eSIM connectivity issues come down to a few simple settings—and you can fix most of them in minutes. This expert-backed checklist walks you through exactly what to do before you even think about contacting support. And no, you don’t need to delete anything. Let’s get you connected.
The Golden Rule: Don’t Panic—Just Restart
It sounds too simple, but this step alone solves most problems.
-
Quick Fix 1: Toggle Flight Mode
Turn Flight Mode ON for 30 seconds, then OFF again. This forces the device to reset its network connection. -
Quick Fix 2: Fully Restart Your Device
Power your phone off and back on. It’s not old-school—it’s effective.
Important: Do not delete your eSIM profile. Most QR codes are one-time use. If you delete it, you’ll likely need a replacement, which slows everything down.
Once that’s done, move to Phase 1.
Phase 1: The Essential Data Settings
This phase solves the classic “Connected, but no internet” or “No data” issues.
Step 1: Turn On Data Roaming
Travel eSIMs connect as “guests” on local partner networks—data roaming is not optional, it’s required.
On iOS:
Settings → Mobile (or Mobile Data) → [Your eSIM] → Data Roaming ON
On Android:
Settings → Connections → Mobile Networks → Data Roaming ON
Step 2: Set the eSIM as Your Data Line
If your physical SIM (or another eSIM) is still set as the default data line, your phone will ignore the travel eSIM.
- iOS: Settings → Mobile (or Mobile Data) → Mobile Data → Select your eSIM
- Android: Settings → Connections → SIM Manager / SIMs → Mobile Data → Select your eSIM
If you’ve done Steps 1 & 2 and still no luck, move to the next phase.
Phase 2: The Technical Deep Dive (Where Most People Get Stuck)
This is where expert knowledge kicks in.
Step 3: Check the APN (Access Point Name)
Think of the APN as the address your phone uses to reach the internet gateway. It’s usually automatic, but if it’s blank or wrong—you won’t connect.
Your APN should be listed in your Global Starlink order confirmation—use the exact APN for your plan and destination.
On iOS:
Settings → Mobile → [Your eSIM] → Mobile Data Network — ensure the APN field matches exactly.
On Android:
Settings → Mobile Networks → Access Point Names → [Your eSIM] — add a new APN or edit the existing one, save, and select it.
Step 4: Manually Select a Network
Sometimes the phone grabs a non-partner network and just sits there doing nothing. Choose a supported partner manually.
- Open Network Selection.
- Turn Automatic off.
- Select a listed network manually (for example, Vodafone, Orange, O2—varies by country and product).
- If the first one fails to register or shows no data, try the next option.
Still offline? Time for the final checks.
Phase 3: Compatibility & Coverage Checks
Before you blame the eSIM, rule out these three common blockers.
Check 1: Is Your Device Unlocked?
Carrier-locked phones—common in the US and Japan—won’t accept international eSIMs. If your device is locked to a carrier, contact them to request an unlock before travelling.
Check 2: Has the Plan Expired or Run Out of Data?
Open your Global Starlink dashboard or app and confirm:
- Your plan status is Active.
- You have remaining data.
- The validity period hasn’t lapsed.
If the plan shows “Expired” or “0 MB remaining”, that’s your answer.
Check 3: Is Your Software Up to Date?
Some older OS versions don’t support newer eSIM functions.
- iOS: Update to iOS 15 or later.
- Android: Android 11 or later recommended.

- Auto network selection picking a non-partner
Fix those, and you’re online. You’re not stuck—you just needed the right checklist. Now you’ve got it.
