eSIM for Indonesia: Bali, Jakarta and the IMEI Rule Nobody Warns You About

Indonesia is straightforward for a two-week holiday and complicated for anyone staying longer, because of a registration rule that applies to the handset rather than the SIM. If you are flying to Bali for a fortnight, the only decision is how much data to buy. If you are staying three months to work remotely, there is something you need to deal with in your first weeks. This guide covers both.

What is the IMEI registration rule in Indonesia?

Indonesia operates an IMEI registration system: every handset using an Indonesian network must have its serial number registered in a government database. Phones brought in by visitors get a grace period commonly reported as around 90 days, after which an unregistered device loses access to Indonesian mobile networks entirely.

The crucial detail is that the block applies to the phone, not the SIM or eSIM. Buying a new plan will not fix it, and neither will swapping to a different provider, because the network is refusing the device itself. A phone that stops working at the end of that window stays stopped until the IMEI is registered.

Registration is done through customs, either at the airport on arrival or at a customs office afterwards, and personal devices are normally handled free within a declared allowance, with import duty above it. Rules and timescales change, so check the current position with Indonesian customs before a long stay rather than relying on a travel guide.

Does the IMEI rule affect short holidays?

No. A visitor on a two- or three-week trip finishes travelling long before the grace period runs out, and never encounters the system at all. The rule only becomes relevant if you are in the country continuously for roughly three months or more — the digital nomad case, not the holiday case.

It also resets in practice for people who leave and return, which is why many long-stay visitors in Bali do visa runs that coincidentally sidestep the issue. If you plan to stay put for a full season, register the device properly rather than relying on that.

Which networks does an Indonesian eSIM use?

The plans in our catalogue connect to Telkomsel, Indosat and 3 (Hutchison), all on 5G. Telkomsel has the widest reach outside the main islands and is the one that holds up in eastern Indonesia; Indosat and 3 are strong in Java and Bali and thinner once you leave the populated west.

Coverage across Bali, Lombok and Java is good, including the south Bali strip, Ubud and Canggu where most visitors base themselves. It degrades in the Gili Islands, inland Flores, Sumba and the Raja Ampat area, where you should plan for intermittent service and download maps in advance.

What do eSIM plans for Indonesia cost?

Our Indonesia catalogue holds 12 plans. Prices start from around €3.99 for 1 GB over 7 days, from around €6.49 for 2 GB over 15 days, and from around €12.49 for 5 GB over 30 days. Unlimited options begin from around €9.99 for three days and extend to 30 days.

Treat these as indicative — the table on this page is generated from current stock and shows today's figure. The catalogue runs up to 20 GB over 30 days and unlimited over 30 days, both of which are aimed at people working from Bali rather than holidaying there.

How much data do I need for two weeks in Bali?

Around 8 to 11 GB, working from the usual 0.6 to 0.8 GB per day. Bali pushes towards the upper end because distances are longer than they look, scooter navigation runs constantly, and ride-hailing apps keep maps and location services active for most of every journey.

Villa and café Wi-Fi in the main areas is widespread and often genuinely fast, which takes the heavy lifting off your plan. If you are working remotely, the calculation changes entirely: video calls and file sync put you well beyond the holiday benchmark, and a 20 GB or unlimited plan is the realistic choice.

Can I use the eSIM for tethering in Indonesia?

Generally yes, and it is a common use case for remote workers in Canggu and Ubud where café Wi-Fi can be crowded in the afternoons. Tethering a laptop multiplies consumption several times over, so size the plan for laptop use rather than phone use if that is the plan.

Be realistic about what the connection is for. A mobile network handles email, documents and most video calls well; it handles large uploads and long calls on a shared evening cell less well. Keep a fixed connection as the primary where the work depends on it.

Will my phone still receive calls on my own number?

Yes. The eSIM is added as a second line, so your existing SIM or profile keeps handling calls and SMS on your home number. Set the eSIM as the data line and turn data roaming off on the home line so background apps cannot quietly use it at international rates.

This is also why the IMEI question matters for long stays: the restriction is on the handset, so it would take your home line offline in Indonesia too, not just the local data plan.
