FAQ
Is my phone compatible with an eSIM?
Most recent iPhones (XS and newer), Google Pixels, and flagship Samsung Galaxy models support eSIM. Check your settings for an "Add eSIM" option, and make sure your phone is carrier-unlocked.
When should I install the eSIM?
Install it before you travel using your home Wi-Fi, then simply activate the data line when you arrive in Indonesia. Installation does not start your plan.
Can I keep my WhatsApp number?
Yes. WhatsApp is tied to your existing phone number, not the eSIM data line, so it keeps working normally while you use the eSIM for data.
Yes. Indonesia has broad 4G coverage and expanding 5G in major cities, and a HelloSIM eSIM works across popular destinations like Bali, Jakarta, and Yogyakarta, provided your phone is eSIM-capable and carrier-unlocked.
Is my phone compatible with a HelloSIM eSIM for Indonesia?
Most phones from 2018 onward support eSIM, including iPhone XS and newer, Google Pixel 3 and later, and recent Samsung Galaxy S, Note, and Z models. Your phone also needs to be carrier-unlocked.
How do I check if my phone supports eSIM before my Indonesia trip?
On iPhone open Settings, Cellular and look for Add eSIM, or check Settings, General, About for an EID. On Android, look under Settings, Network and internet, SIMs for an Add eSIM option.
How do I install a HelloSIM eSIM for Indonesia?
After purchase you receive a QR code by email. On iPhone go to Settings, Cellular, Add eSIM, Use QR Code and scan it; on Android go to Settings, Network and internet, SIMs, Add eSIM and scan. Do this over Wi-Fi before you fly.
Can I install my Indonesia eSIM before I leave home?
Yes, and it is recommended. Install over Wi-Fi at home so the profile is ready, but wait to turn on data roaming until you arrive so your plan validity lines up with your trip dates.
Do I need my passport to get a HelloSIM eSIM for Indonesia?
No. Buying a local Indonesian SIM requires passport registration, and unregistered SIMs get blocked. A HelloSIM eSIM is purchased online with no paperwork and is ready before you land.
Should I activate my Indonesia eSIM before flying or after landing?
Install it beforehand but activate or enable the line after you land, so the validity period starts with your trip. Many HelloSIM plans begin counting from the first network connection.
Will I have internet as soon as I land in Bali or Jakarta?
Yes. Ngurah Rai (Denpasar) and Soekarno-Hatta (Jakarta) airports have strong coverage, so once you enable your eSIM line and turn on data roaming after landing, you should connect quickly to book a ride or transfer.
Which networks does HelloSIM use in Indonesia?
HelloSIM connects through major Indonesian operators such as Telkomsel, Indosat Ooredoo Hutchison, and XL Axiata via roaming agreements. Your phone automatically selects the strongest available partner network.
Is there 5G in Indonesia with a HelloSIM eSIM?
5G is available in parts of Jakarta, Surabaya, Bali, and other major cities, with 4G LTE covering most populated and tourist areas. If your plan and device support 5G you get it where present, otherwise fast 4G.
How good is mobile coverage across Indonesia?
Coverage is strong in cities and main tourist areas across Java, Bali, and Lombok. Telkomsel generally has the widest reach in remote islands, but very rural areas, small islands, and jungle or mountain regions can be patchy.
Which network is best for coverage on remote Indonesian islands?
Telkomsel typically has the broadest coverage in remote and outer-island areas. HelloSIM's partner roaming selects the strongest available signal automatically, but expect thinner coverage on small islands and in remote highlands.
How much data do I need for a week in Indonesia?
For a week of maps, ride-hailing, browsing, messaging, and social media, most travelers are comfortable with around 5 to 10 GB. If you stream, video call, or tether devices, choose a larger plan.
How much data do I need for two weeks in Bali?
For a two-week Bali stay with heavy app use, navigation, and photo and video sharing, something in the range of 15 to 25 GB is a comfortable buffer. You can top up anytime if you run low.
How much do eSIM data plans for Indonesia typically cost?
Prices depend on data amount and validity, but Indonesia eSIM plans are generally affordable and cheaper than home-carrier roaming. Check the HelloSIM Indonesia page for current plans and exact pricing.
How long are HelloSIM Indonesia plans valid?
Validity varies by plan, commonly from about a week up to 30 days. Choose a window that covers your full trip, since unused validity typically does not roll over once it expires.
Can I use my HelloSIM eSIM as a hotspot in Indonesia?
Yes, tethering and personal hotspot are supported, so you can share data with a laptop, tablet, or travel companion. Hotspot use consumes data quickly, so pick a plan with enough allowance.
Can I keep my home number while using the eSIM in Indonesia?
Yes. In dual-SIM mode your physical SIM stays active for your home number's calls and texts, while the HelloSIM eSIM handles affordable data. Keep roaming off on your home line to avoid charges.
Does the Indonesia eSIM include calls and SMS or is it data-only?
HelloSIM Indonesia plans are typically data-only. Use WhatsApp, which is widely used in Indonesia, plus FaceTime, Messenger, or Signal for calls and texts over data. Keep your home SIM for standard SMS codes if needed.
Can I contact villas, drivers, and tours in Indonesia with a data-only eSIM?
Yes, because most accommodations, drivers, and tour operators in Indonesia coordinate over WhatsApp, which works on your eSIM data. For direct calls to local landlines, keep a voice option available.
Do I need to set an APN manually for Indonesia?
Usually not, since the eSIM configures the APN automatically. If data does not work after activation, HelloSIM provides the correct APN to enter under cellular settings, and a restart often resolves it.
What settings do I turn on to get data working in Indonesia?
Set the HelloSIM eSIM as your cellular data line, enable Data Roaming for that line, and switch off roaming on your home line. If it does not connect, toggle airplane mode on and off or restart the phone.
Why does my eSIM say No Service in Indonesia?
Check that data roaming is on for the eSIM line and that the line is selected for data. Restart the phone, then try selecting an operator like Telkomsel or XL manually under network selection. In remote areas, weak signal can also cause this.
My Indonesia eSIM is not registering on a network, what do I do?
Toggle airplane mode, restart the phone, confirm data roaming is enabled on the eSIM line, and try manual network selection. Make sure the plan is activated and its validity has started; if it still fails, contact HelloSIM support.
Can I top up my HelloSIM eSIM if I run out of data in Indonesia?
Yes. Add more data through your HelloSIM account without swapping eSIMs or scanning a new QR code. Top up before you fully run out so you avoid any gap in connectivity.
What happens when my data runs out in Indonesia?
Your connection stops until you top up or buy a new plan, with no surprise overage charges. You can add data from your HelloSIM account whenever you find Wi-Fi.
Can I use my Indonesia eSIM in Singapore, Malaysia, or Thailand?
A country-specific Indonesia plan works only in Indonesia. If your trip includes other Southeast Asian countries, choose a regional Asia plan that lists them, or buy a separate eSIM for each destination.
Is there a regional plan that covers Indonesia and nearby countries?
HelloSIM offers regional and multi-country options, but coverage lists vary, so always confirm each country is included before buying. For an Indonesia-only trip, a dedicated Indonesia plan is the simplest choice.
What is the emergency phone number in Indonesia?
Indonesia's unified emergency number is 112, which reaches police, ambulance, and fire services. You can also dial 110 for police and 118 or 119 for ambulance. Emergency calls work even with limited signal.
What are the main areas I will use my eSIM in Indonesia?
Travelers typically use data heavily in Bali (Seminyak, Ubud, Canggu, Uluwatu), Jakarta, Yogyakarta, Lombok, and the Gili Islands. Cities and popular tourist areas have strong coverage.
What download speeds can I expect in Indonesia?
In cities and busy tourist areas you can see fast 4G and some 5G speeds fine for streaming and video calls. Speeds drop on small islands, in rural areas, and around remote beaches, temples, and highlands.
Will my eSIM work on the Gili Islands and other small islands?
Coverage reaches many popular smaller islands like the Gilis, but it can be slower and less reliable than on the mainland. Telkomsel tends to perform best; download maps and key info before island-hopping.
Do I need an eSIM if my hotel or villa has Wi-Fi in Indonesia?
Wi-Fi is common in accommodations but can be slow, especially in villas and on islands. An eSIM gives you dependable data for ride-hailing, navigation, translation, and staying in touch while you are out and about.
Can I use Gojek and Grab in Indonesia with my eSIM?
Yes. Gojek and Grab both work well on eSIM data and are the easiest way to get rides, food delivery, and more across Indonesian cities and Bali. Reliable data lets you track drivers and share trips.
Should I download offline maps for Indonesia?
Yes. Offline maps of Bali, your islands, and driving routes are useful for navigating, handling coverage gaps in remote areas, and saving data. They keep navigation working even where signal is weak.
How many eSIMs can my phone store for an Indonesia trip?
Modern iPhones and many Android phones can store several eSIM profiles and keep two lines active at once, so you can have your home eSIM and the HelloSIM Indonesia eSIM installed together and switch as needed.
Will using the eSIM in Indonesia drain my battery faster?
Heavy use of maps, ride-hailing, streaming, and hotspot, plus searching for signal in weak-coverage island or highland areas, can drain battery faster. Carry a power bank for long days out and island trips.
Can I get a refund if I bought the wrong Indonesia eSIM?
If an eSIM has not been installed or activated, it is generally eligible for support review under HelloSIM's refund policy. Contact support with your order details before installing and they will help.
Do I need to remove my physical SIM to use the eSIM in Indonesia?
No. The eSIM runs alongside your existing physical SIM. Keep your home SIM in the phone for your number and use the HelloSIM eSIM as your data line, choosing which line handles data.
Is the eSIM data connection in Indonesia secure for banking and payments?
Mobile data is generally safer than open public Wi-Fi for sensitive tasks like banking. Using your eSIM data instead of unknown cafe or beach-bar hotspots is a good habit while traveling in Indonesia.
What should I do with my HelloSIM Indonesia eSIM after my trip?
Once the plan expires you can delete the eSIM profile in your phone settings, or keep it for a future visit and top up later. Reset your home line's roaming settings to normal when you return.
