eSIM Not Working in Indonesia? Complete 2026 Troubleshooting Guide

You have arrived in Indonesia, installed your eSIM, and expected everything to work immediately.

Instead, your phone shows:

• No Service
• No Internet Connection
• Emergency Calls Only
• No Mobile Data
• Searching for Network
• Unable to Activate eSIM

While this situation can be frustrating, the good news is that most Indonesia eSIM issues are caused by simple device settings and can usually be resolved within a few minutes.

Quick answer: the most common reasons an eSIM does not work in Indonesia are disabled data roaming, the wrong mobile data line being selected, incorrect APN settings, delayed network registration after arrival, or incomplete installation.

Before You Start

Before troubleshooting, confirm the following:

• The eSIM was successfully installed.
• Your phone supports eSIM technology.
• Your device is carrier unlocked.
• You are physically located in Indonesia.
• The eSIM has not expired.

If all of these conditions are met, continue with the steps below.

Problem #1: Data Roaming Is Disabled

This is the most common reason an eSIM does not work after arrival.

Most travel eSIMs require roaming to be enabled.

iPhone

1. Settings
2. Mobile Service
3. Select your Indonesia eSIM
4. Data Roaming
5. Turn ON

Android

1. Settings
2. Network & Internet
3. SIM Manager
4. Select Indonesia eSIM
5. Enable Data Roaming

After enabling roaming, wait several minutes for the device to connect.

Problem #2: Wrong Mobile Data Line Selected

If your primary SIM remains selected for mobile data, the Indonesia eSIM may never be used.

Verify that the eSIM is the active data line.

iPhone

1. Settings
2. Mobile Service
3. Mobile Data
4. Select Indonesia eSIM

Android

1. Settings
2. SIM Manager
3. Mobile Data
4. Select Indonesia eSIM

Problem #3: Automatic Data Switching Is Enabled

Many phones automatically switch between SIM cards.

This can interfere with travel eSIM connectivity.

Disable:

• Allow Mobile Data Switching
• Automatic SIM Switching
• Smart Data Switching

Then restart the phone.

Problem #4: APN Settings Are Missing

Some eSIMs require manual APN configuration.

If your provider requires APN setup, verify the settings.

Setting	Value
APN	data.esim

Leave other fields empty unless instructed otherwise.

Problem #5: Phone Needs a Restart

Many devices need a restart after eSIM installation.

Try:

1. Turn the phone off.
2. Wait 30 seconds.
3. Turn it back on.
4. Wait several minutes.

This often resolves network registration issues.

Problem #6: Airplane Mode Refresh

A network refresh can help the phone reconnect.

1. Enable Airplane Mode.
2. Wait 30 seconds.
3. Disable Airplane Mode.
4. Wait several minutes.

The device will search for available networks again.

Problem #7: Manual Network Selection Required

Sometimes automatic network selection does not work immediately.

Try selecting a network manually.

iPhone

1. Settings
2. Mobile Service
3. Network Selection
4. Disable Automatic
5. Select an available network

Android

1. Settings
2. Mobile Networks
3. Network Operators
4. Disable Automatic
5. Select an available network

Problem #8: eSIM Installed Too Early

Many travelers install their eSIM before departure.

This is completely normal.

Most travel eSIMs only become active when the device connects in the destination country.

If you installed your eSIM before leaving home, this does not mean there is a problem.

Problem #9: No Coverage in Current Location

Although major destinations have strong coverage, some remote locations may experience weaker service.

This is especially true in:

• Remote islands
• Mountain regions
• National parks
• Boat excursions
• Rural villages

Try moving to another location and testing again.

Problem #10: Device Is Not eSIM Compatible

Not all phones support eSIM.

Before purchasing any eSIM, verify compatibility.

Final Recommendation
