eSIM Installed But No Data?

The 60-Second Fix (Try This First)

Airplane Mode ON → wait 10 seconds → Airplane Mode OFF. This forces a network re-scan and fixes most issues.

Data Roaming — The #1 Culprit

• Settings → Cellular/Mobile Data → tap your eSIM → Data Roaming ON
• Yes, even if you're in the country the eSIM is for
• eSIMs are technically "roaming" on partner networks
• Without data roaming, your phone won't connect

Can't find Data Roaming on iPhone? The per-line Data Roaming switch only shows up once the eSIM line is installed and ON — open Settings → Cellular, confirm the simZILLA line appears under SIMs and is toggled ON, tap the line name, then switch Data Roaming on. If the line is missing or the toggle stays hidden, toggle Airplane Mode, wait 10 seconds, turn it off, and reopen Settings.

Check You're Using the Right SIM for Data

• Settings → Cellular/Mobile Data → Cellular Data → select your eSIM
• If your primary SIM is selected, you're using roaming data (expensive)
• Turn OFF "Allow Cellular Data Switching" so your phone doesn't switch back

APN Settings — The Hidden Fix

• Some carriers need manual APN configuration
• Settings → Cellular → tap your eSIM → Cellular Data Network
• APN should be "internet" or "wholesale" (varies by carrier)
• If the APN field is empty, your eSIM didn't configure automatically
• Contact support for the correct APN for your plan

Manual Network Selection

• Settings → Cellular → tap your eSIM → Network Selection
• Turn OFF "Automatic"
• Wait for networks to appear (10-30 seconds)
• Try each network. Some take longer to register.
• If one works, leave it. Don't switch back to Automatic.

Check Your Coverage

• Are you in a country the plan covers?
• Regional plans have specific country lists — check yours
• Some plans exclude certain countries (e.g., "Europe excl. France")
• If you're in a covered country and it still doesn't work, the issue is configuration, not coverage

Restart Your Phone

Turn it off completely. Wait 30 seconds. Turn it back on. Phones cache network state. A restart clears it. This fixes more issues than you'd think.

Check for Carrier Profile Updates

• Settings → General → About (iOS)
• If a carrier update is available, you'll see a popup
• Install it — carrier profiles include network configuration data

Still Not Working?

• The eSIM may not have provisioned correctly on the supplier side
• Email support with your order ID
• We can check the eSIM status and re-issue if needed
• This is rare but it happens — it's a supplier issue, not your fault

Key Takeaways

• Data Roaming ON — always, for every eSIM
• Airplane Mode toggle fixes most issues
• Check you're using the eSIM for data, not your primary SIM
• Manual network selection beats automatic when auto fails
• Restart your phone before contacting support
