What Are the Common Problems with Tourist eSIMs in Indonesia?

A tourist eSIM makes it easier to get online in Indonesia, but travellers can still run into trouble at installation, activation, registration, or everyday use. The good news is that many of these problems come down to a few settings, and a handful of basic checks resolves a lot of them. Below, each problem comes with its likely cause and the steps to try, in the order that usually makes sense.

1. Your Phone Doesn't Support eSIM or Is Carrier-Locked

• The phone doesn't have eSIM technology, or your specific model or regional variant doesn't support it.
• The phone is locked to your home carrier and can't use another provider's eSIM. Apple's iPhone guide says that to use two different carriers, the iPhone must be unlocked.

1. Look in your cellular settings for an Add eSIM or Add Cellular Plan option. If it's missing, the phone may not support eSIM.
2. Confirm the exact model and regional variant against the provider's list. BaliSIM's is the eSIM-compatible phones list.
3. On an iPhone, check Settings, General, About, Carrier Lock. It should read "No SIM restrictions". On other phones, ask your carrier.
4. If the phone is locked, contact the original carrier and ask for an unlock before you travel.

2. The eSIM QR Code Won't Scan or Installation Fails

• The internet connection dropped during installation.
• The QR code has already been used, or is no longer valid. BaliSIM's pages say each eSIM works on one device.
• Manual details were typed incorrectly.
• A device compatibility or software issue.

1. Connect to stable Wi-Fi and follow your provider's installation instructions.
2. If scanning fails, show the QR code on another screen, or use the manual option (on iPhone, "Enter Details Manually"). BaliSIM's guide to manually installing an eSIM walks through it.
3. Check whether the QR code has already been used on another install.
4. If your provider rejects the installation details, ask it for help.

3. The eSIM Is Installed but Has No Internet

A successful installation doesn't always mean the eSIM is ready to carry data.

• The wrong SIM is selected for mobile data.
• Data roaming is off, when your provider requires it on.
• The plan hasn't activated yet. BaliSIM's FAQ says validity usually begins when the eSIM first connects to a local network in Indonesia.
• The phone is on an unsupported network.
• The plan has expired or its data has run out.

1. Make sure the eSIM line is switched on, and select it as the mobile data line.
2. Turn on data roaming if your provider's instructions require it. Airalo's Help Center notes that on iPhone roaming can be set per SIM, while on Android it usually applies to all SIMs, so turn your primary SIM's data off to avoid roaming charges.
3. Check the plan's activation conditions, validity dates, and remaining data.
4. Restart the phone.
5. If your provider supplies APN settings and they aren't applied automatically, enter them exactly as given.

4. The eSIM Shows No Service or Weak Signal

Signal depends on the local network, your destination, your device, and your surroundings. No operator guarantees coverage everywhere in Indonesia.

• Limited local network coverage.
• Indoor locations or geographic obstacles such as valleys.
• Remote islands, mountains, or sea routes.
• A temporary network outage.
• The phone is stuck on the wrong network.

1. Move to an open area with better reception, if it's safe.
2. Switch airplane mode on, wait a few seconds, then off.
3. Restart the device.
4. Try automatic network selection.
5. If your provider recommends it, select a supported network manually. Airalo's Help Center says that if nothing else helps, your area's signal may not be strong enough to connect.

5. Passport or IMEI Registration Problems

Some Indonesian tourist SIM and eSIM products require identity or device registration. Others don't. Requirements vary by provider and product, and not every travel eSIM needs Indonesian passport or IMEI registration. BaliSIM's product pages, for example, ask for a passport photo and an IMEI photo through an online form, and Tri publishes its own steps on its Tourist Pass and IMEI Registration page. Don't assume one provider's rules apply to another.

• Passport details were entered incorrectly.
• The IMEI submitted doesn't match the phone you're using.
• A document is missing or a photo is unclear.
• The submitted information doesn't match the documents.
• The registration is still being processed.

1. Recheck the passport information.
2. Confirm the correct IMEI was submitted. Dial *#06# to see it, and note that dual-SIM phones can show more than one.
3. Upload clear, readable documents.
4. Read your provider's registration instructions. BaliSIM's are on its registration page.
5. Contact support if registration stays unsuccessful.

6. Your Data Is Slow or Runs Out Too Quickly

• Video streaming and social media use a lot of data.
• Automatic app updates and cloud backups run in the background.
• Hotspot and tethering draw from the same allowance.
• Network congestion in busy areas.
• Plan speed limits or fair-use policies. Holafly's Indonesia page says fair-use speed reductions can apply to its unlimited plan.

1. Check mobile data usage per app in your phone settings.
2. Turn off unnecessary background data and automatic updates.
3. Lower video streaming quality.
4. Check hotspot restrictions and plan conditions.
5. Read the provider's fair-use policy, especially on unlimited plans. Don't assume every unlimited plan has the same limits.

7. Hotspot or Tethering Doesn't Work

Hotspot support depends on the plan and the provider. Holafly's Indonesia page, for example, lists 1 GB of shareable data per day, while BaliSIM's product pages list hotspot as included. Check yours before assuming.

1. Check that your plan supports hotspot use.
2. Switch on Personal Hotspot or Mobile Hotspot in settings.
3. Confirm the eSIM is the line selected for mobile data.
4. Restart the device if the hotspot isn't detected.
5. If hotspot is included but still unavailable, contact your provider.

8. You Can't Reach Customer Support Without Internet

If the connection itself is the problem, reaching support is harder. Prepare before you fly:

• Save your provider's support email, WhatsApp number, and help-centre URL. BaliSIM's support channels are WhatsApp +62 813-3977-4203 and email at cs@balisim.com.
• Download the installation and troubleshooting instructions.
• Keep your order confirmation and eSIM details accessible offline.
• Save the QR code securely.
• Plan to use hotel Wi-Fi or another connection to contact support. Some providers' apps also let you contact support without an active plan, as Airalo's Help Center describes.

Contact your provider rather than changing settings over and over once you've worked through the checklist below. Random changes can make the problem harder to diagnose.

Mistakes That Make eSIM Problems Harder to Fix

A few well-meant reactions can turn a small issue into a harder one. Avoid these:

• Deleting the eSIM or scanning the QR code again and again. This is the most common way to lose a working profile. Contact your provider first.
• Leaving your home SIM's data and roaming on. With both lines active, your phone may use the wrong one and charge you roaming fees. Set the travel eSIM as the data line and switch off your home SIM's mobile data, as Airalo's Help Center advises.
• Changing advanced network settings without instructions. Resetting network settings clears your saved Wi-Fi, Bluetooth, and mobile network settings, so treat it as a last resort and ask your provider before trying it.
• Mistaking a coverage gap for a faulty eSIM. If the eSIM works in one place and not in another, the cause is probably signal at that location, not the eSIM.
• Treating a pending registration as a failure. Some products process registration before the eSIM works. Check the status with your provider rather than resubmitting documents.
• Waiting until you land to install. Installation needs a stable connection, and activation rules differ by product. Where your provider allows it, install over home Wi-Fi so any problem shows up before you travel.

If you're unsure which kind of problem you have, the quick diagnosis table near the top is a good place to start. When in doubt, stop changing settings and ask the provider.
