Telkomsel and travel eSIM in Indonesia
Telkomsel is one of the networks your eSIM may use in Indonesia. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 105 of the 105 Indonesia plans we sell name Telkomsel as a reachable network, at 4G and 5G.
- Telkomsel runs LTE on B3, B8, B40 and 5G on n40, n1; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
Telkomsel in brief
Telkomsel states its 5G runs on n40 (2300 MHz) and n1 (2100 MHz), and its 3G network was switched off nationwide in June 2023.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
Telkomsel's bands and technology
| Item | Telkomsel |
|---|---|
| LTE (4G) | B3, B8, B40 |
| 5G NR | n40, n1 |
| 5G launched | Live |
| 3G | Shut down |
| Network code (MCC-MNC) | 510-10 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use Telkomsel if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Telkomsel's coverage map
Telkomsel publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Telkomsel's own network; a roaming plan may not get every technology it shows.
Who licenses Telkomsel
Mobile networks in Indonesia are licensed, and their spectrum assigned, by the Ministry of Communication and Digital Affairs (Komdigi) (Komdigi). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
The plans on our shelf that name Telkomsel
From the supplier record behind each package, 105 of the 105 plans we currently sell for Indonesia declare Telkomsel as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
A plan naming Telkomsel means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
Telkomsel beside the other networks in Indonesia
| Network | LTE bands | 5G bands |
|---|---|---|
| Telkomsel | B3, B8, B40 | n40, n1 |
| Indosat Ooredoo Hutchison | B1, B5, B40 | Not verified |
A band shared across networks is one a single phone can use on all of them.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Telkomsel is weak where you are, try selecting Indosat Ooredoo Hutchison manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Telkomsel?+
105 of our plans name Telkomsel as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for Telkomsel?+
At least one of these, LTE: B3, B8, B40; 5G: n40, n1. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does Telkomsel run 5G, and will my plan get it?+
Yes. Telkomsel has run commercial 5G, on n40, n1. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
