Installation

eSIM installation: iOS and Android

iOS installation (iPhone)

Open Settings > Cellular > Add eSIM
Select "Use QR Code"
Scan the QR code from your Nomad confirmation email
Label the plan (e.g., "Indonesia Travel")
Set as cellular data line (not your default for calls)
Do NOT enable data roaming yet
Confirm the plan appears under Settings > Cellular

iOS 18: the "Add eSIM" option appears under Settings > Cellular > Add Cellular Plan. iOS 17 and earlier: Settings > Cellular > Add eSIM.

Android installation (Stock Android)

Open Settings > Network & Internet > SIMs > Add eSIM
Select "Scan QR code"
Scan the QR code from your Nomad confirmation email
Name the profile (e.g., "Indonesia Data")
Set as mobile data SIM
Do NOT enable data roaming yet
Verify the plan in SIM manager

Manual installation (if QR fails)

If the QR code does not scan, use manual entry:

Go to Settings > Cellular > Add eSIM
Select "Enter Details Manually"
Enter the SM-DP+ address from your provider email
Enter the activation code
Complete the setup as with the QR method

Use manual entry when: camera cannot read the QR code, the email was forwarded without the image, or you are installing on a second device.

Configuration

APN setup for Indonesia eSIM

Automatic APN configuration

Most eSIM profiles auto-configure APN settings for Telkomsel's network. After installation, verify the APN is set correctly:

iPhone: Settings > Cellular > Cellular Data Options > Cellular Data Network
Android: Settings > Network & Internet > SIMs > (travel eSIM) > Access Point Names

A correctly configured APN shows the carrier name and data type. If the APN field is blank, your phone will attempt to auto-fill on first connection.

Manual APN entry

If auto-configuration fails (rare, typically older Android devices), enter APN settings manually. Check your provider's confirmation email for the exact values. Common fields:

APN configuration fields
Field	Value
APN Name	From provider email
APN	Provider-specific value
Authentication	None (most providers)
APN Protocol	IPv4/IPv6

Provider-specific APN values override Telkomsel's carrier defaults. Always use the values from your provider, not generic carrier APNs.

5G and LTE band selection

5G is available in Indonesia (limited coverage). To force a network type:

iPhone: Settings > Cellular > Cellular Data Options > Voice & Data > 5G Auto / LTE
Android: Settings > Network > Preferred network type > 5G/LTE/3G Auto

Switch to LTE-only to conserve battery in rural areas without 5G towers. Telkomsel launched 5G in Jakarta and Bali in 2023; expansion slow across archipelago

Verification

Verifying your Indonesia data connection

Signal and network verification

Check your status bar: the carrier name should show Telkomselor a roaming indicator. Signal bars confirm connection strength. Go to Settings > Cellular to verify data usage is counting on the travel eSIM line.

"Telkomsel" or roaming icon: Connected and working
"Searching...": Still connecting, wait 2-3 minutes
"No Service": Data roaming is off or wrong SIM line selected

Speed test

Run fast.com or Speedtest.net to verify your connection speed. Expected speeds on Telkomsel: approximately 32 Mbps download. Speeds vary by location: airports and city centers are fastest, rural areas slower.

Verifying data roaming is active

Go to Settings > Cellular > (travel eSIM) > Data Roaming: ON. Test by opening any website in your browser. If it loads, roaming is active. If not, toggle data roaming off and back on, then restart your phone.

Dual-SIM verification

Confirm your home SIM still receives calls and texts. Confirm the travel eSIM handles all data traffic. Test: send yourself a text message to your home number. Then load a webpage. Both should work simultaneously. If data routes through the home SIM instead, switch your cellular data line to the travel eSIM.

Airport Guide

Arriving at Ngurah Rai / Bali (DPS) / Soekarno-Hatta (CGK) with your eSIM

Before boarding

Set up your Indonesia eSIM before you leave the house. The QR code scan takes 90 seconds over a stable connection. Use your home WiFi, not mobile data or airport networks. After the profile installs, set the eSIM to off so Telkomsel does not register it during a layover. The data counter starts on first network connection, not at installation time.

During the flight

Use the flight to prepare your phone settings. Open Settings, navigate to Cellular, and verify the Indonesia eSIM is assigned as your data line. Turn off data roaming on your home carrier line. When you land, the only toggle left is enabling the travel eSIM.

After landing

After touchdown, open Settings, enable the Indonesia eSIM, and turn on data roaming for the travel line. Telkomsel registers the profile in 45-90 seconds. Check your status bar for the carrier name and signal bars. The SIM counter from Telkomsel and XL Axiata is in the arrivals hall — expect a 10-20 min; IMEI check may add time wait and $5-15 for 5-20GB / 15-30 days for a tourist plan. Walk past it.

Leaving the airport

Your eSIM gives you data before you clear customs. By the time you reach ground transport, your map is loaded, your ride is booked, and your hotel has your arrival message. Zero idle time at Ngurah Rai / Bali (DPS) / Soekarno-Hatta (CGK). Indonesia's emergency number is 112/119 — it works without data, but having your eSIM active means you can also share GPS coordinates with emergency services.

Carrier Config

Carrier troubleshooting for Indonesia

Telkomsel

APN: "telkomsel" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Telkomsel" from the list. The phone locks onto Telkomsel's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 29-32 Mbps in urban areas, 10-16 Mbps in rural coverage

Common issue: Telkomsel's network occasionally delays eSIM profile registration during peak hours at major airports. If your phone shows "Searching..." for more than 2 minutes, turn off Automatic network selection, wait 10 seconds, then select Telkomsel manually from the operator list.

Resolution: Restart your phone after adjusting network settings. Telkomsel typically completes registration within 60-90 seconds of a fresh boot. If the issue persists, remove and re-add the eSIM profile using the manual activation code from your provider's confirmation email.

XL Axiata

APN: "internet" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "XL Axiata" from the list. The phone locks onto XL Axiata's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 19-27 Mbps in cities, 6-13 Mbps outside metro areas

Common issue: Some eSIM plans routed through XL Axiata require data roaming to be enabled on the travel SIM line specifically. Leaving it off is the most common reason travelers report zero signal after landing in Indonesia. Check under Settings > Cellular > [Travel eSIM] > Data Roaming.

Resolution: Toggle airplane mode on for 15 seconds, then off. This forces a fresh network scan without a full restart. XL Axiata should appear in your carrier field within 60 seconds. If it does not, use manual network selection to find and choose XL Axiata directly.

Indosat Ooredoo

APN: "indosatooredoo" — enter under Settings > Cellular > Cellular Data Network (iPhone) or Settings > Connections > Mobile Networks > Access Point Names (Samsung). Leave username, password, and proxy fields blank. Save and restart data.

Network selection: Open Settings > Cellular > Network Selection (iPhone) or Settings > Connections > Mobile Networks > Network Operators (Samsung). Turn off Automatic. Wait 10-30 seconds for the carrier list to populate. Select "Indosat Ooredoo" from the list. The phone locks onto Indosat Ooredoo's 5G/LTE band and data resumes within 30 seconds.

Expected speed: 19-27 Mbps in cities, 6-13 Mbps outside metro areas

Common issue: Indosat Ooredoo may show a signal bar but no data if the APN was not auto-configured. This happens on roughly 10-15% of Indonesia eSIM activations. Enter APN "indosatooredoo" manually under Cellular Data Network settings.

Resolution: Reset network settings: Settings > General > Transfer or Reset > Reset Network Settings (iPhone) or Settings > General Management > Reset > Reset Network Settings (Samsung). This clears saved WiFi passwords but resolves most Indosat Ooredoo registration failures. Re-enable the Indonesia eSIM after the reset completes.

Dual SIM

Running two SIMs in Indonesia: data line vs call line

Data line setup

Open Settings > Cellular and tap "Cellular Data." Select the Indonesia eSIM. All data now routes through Telkomsel's local network at local rates. Do not enable "Allow Cellular Data Switching" — that setting lets the phone fall back to your home SIM for data, which triggers international roaming fees without warning.

Calls and SMS

The home SIM stays on for calls and verification texts. When someone dials your regular number, it rings normally. Standard SMS charges from your home carrier may apply for receiving texts abroad — check your plan. All internet-based communication routes through Telkomsel's data network on the Indonesia eSIM.

Emergency dialing

Emergency services in Indonesia are reached at 112/119. Both your home SIM and the travel eSIM can place this call. Data from the eSIM adds GPS location sharing, real-time translation for language barriers, and the ability to look up your embassy's local address and phone number.

Battery impact

Running two SIMs draws 10-15% more battery per day than a single SIM. Both radios maintain separate network connections. If your battery runs low during the day, disable the home SIM temporarily under Settings > Cellular — the Indonesia eSIM is the priority line for data. Re-enable the home SIM when you reach WiFi at your hotel. Indonesia uses Type C/F outlets — carry the right adapter.

Hotspot

Share your Indonesia eSIM data with other devices

Personal hotspot works with most Indonesia eSIM plans from major providers. Enable it under your phone's settings. The hotspot shares your Telkomsel 5G/LTE connection with nearby devices via WiFi, Bluetooth, or USB. WiFi tethering has the widest range (roughly 10 meters) but uses more battery. USB tethering charges your phone while sharing data — ideal for laptop sessions. Expect 19-26 Mbps typical through hotspot on the connected device.

Provider restrictions

Hotspot availability is a plan feature, not a country restriction. Most fixed-data Indonesia plans support tethering. Unlimited plans are the exception — carriers throttle or block hotspot on unlimited tiers to manage network load on Telkomsel's infrastructure. If you need hotspot, buy a fixed-data plan with an explicit hotspot label.

Data impact

Tethering multiplies data use. A single Zoom call uses 300-500 MB/hour. Slack with screen sharing adds 200-400 MB/hour. Background cloud sync on a connected laptop can consume 500 MB-1 GB without any visible activity. Before hotspotting in Indonesia, disable auto-sync and set video calls to audio-only when possible — that drops consumption by 70%.

Registration

Skip Indonesia's SIM registration with eSIM

Buying a physical SIM in Indonesia requires NIK (national ID) or passport required. At Ngurah Rai / Bali (DPS) / Soekarno-Hatta (CGK), the registration process at Telkomsel's counter takes 15-30 minutes: passport scan, photo capture, form completion. Some carriers require biometric verification (fingerprint or face scan). An eSIM purchased online before departure skips this entire process. No documents, no counter, no registration delay. Indonesia also requires IMEI registration for physical SIM cards — a process that can take up to 24 hours to complete. eSIM bypasses IMEI registration entirely.

Peak Season

Indonesia peak season: Apr-Oct, Dec-Jan network advisory

Indonesia's Dry season April-October is peak for Bali. During Apr-Oct, Dec-Jan, Telkomsel's network handles significantly more traffic in tourist areas. Expect 13-19 Mbps during peak congestion in popular districts — still fast enough for maps, messaging, and ride-share apps. Video streaming at peak hours may buffer. Pre-download maps and entertainment before leaving WiFi. Upgrade to a higher data tier (1GB minimum) if traveling during peak months — congestion increases per-MB consumption due to retransmissions.

Connect to Indonesia's 5G network via eSIM

Indonesia's Telkomsel network provides limited 5G availability in select areas. Telkomsel launched 5G in Jakarta and Bali in 2023. Your eSIM connects to 5G automatically if your device supports it. To force 5G: iPhone — Settings > Cellular > Voice & Data > 5G On. Samsung — Settings > Connections > Mobile Networks > Network Mode > 5G/LTE. Choose "5G Auto" to balance speed and battery life. Telkomsel delivers 32 Mbps average on 5G bands. Outside 5G coverage areas, the phone falls back to LTE without interruption.

WiFi Backup

WiFi and eSIM activation in Indonesia

Indonesia has good WiFi in hotels, malls, and cafes. Free WiFi in most cafes and hotels in Bali and Jakarta. The best approach: install your eSIM at home over your own WiFi before departure. The QR code scan transfers about 500 KB of profile data — it needs a clean connection, not speed. Airport WiFi at Ngurah Rai / Bali (DPS) / Soekarno-Hatta (CGK) uses captive portals that can interrupt the eSIM download. Install at home, travel with confidence.

Activating without WiFi

If you cannot scan the QR code, use manual entry. Your eSIM provider's confirmation email contains an SM-DP+ activation address and activation code. On iPhone: Settings > Cellular > Add eSIM > Enter Details Manually. On Samsung: Settings > Connections > SIM Manager > Add eSIM > Enter Activation Code. Enter the SM-DP+ address and code exactly as shown. This method uses your existing data connection (home carrier or WiFi) and does not require a camera.

Multi-Country

Indonesia eSIM on a multi-country trip

If Indonesia is one stop on a multi-stop Asian itinerary, install all country eSIMs before departure. Most phones store 8 or more eSIM profiles. Label each one clearly: "Indonesia Data," "France Data," etc. At each border, disable the previous country's eSIM and enable the next one. The switch takes 30 seconds under Settings > Cellular. A single-country Indonesia plan on Telkomsel's 5G/LTE network delivers better local coverage than a multi-country regional eSIM — starting at $3.99 for 1GB.

Switching eSIM profiles between countries

At the Indonesia border, open Settings > Cellular (iPhone) or SIM Manager (Samsung). Disable your previous eSIM. Enable the Indonesia profile and set it as the active data line. Turn on data roaming for the Indonesia line. Telkomsel's 5G/LTE network connects within 60-90 seconds. Do not delete the previous eSIM — you may need it on the return leg.

Fixes

What to do when setup fails

"eSIM Not Supported" error

Cause: Your phone is carrier-locked or the model does not support eSIM.

Fix: Contact your home carrier to unlock (24-72 hours). Verify your model supports eSIM at our compatibility list.

"Unable to Activate eSIM" error

Cause: eSIM profile slot is full, or the QR code was already redeemed.

Fix:Delete unused eSIM profiles in Settings > Cellular. iPhones hold 8 profiles (2 active). If the QR shows as used, contact your provider for a replacement code.

Connected but no data

Cause: Data roaming is off on the travel eSIM, or data is routing through the home SIM.

Fix:Settings > Cellular > select travel eSIM > Data Roaming ON. Also verify: Settings > Cellular > Cellular Data > select the travel eSIM as your data line. Restart your phone after making changes.

Slow speeds on Telkomsel

Expected: 32 Mbps. If speeds are noticeably lower: toggle airplane mode on and off. Move to a different area. Try forcing LTE if 5G is congested. During Apr-Oct/Dec-Jan speeds may drop in tourist areas.
