Indonesian Mobile Operators Guide — Telkomsel, Indosat, XL, and More
A complete guide to Indonesia's 6 major mobile operators. Find out which network your family uses and how to top up their phone credit from abroad.
Indonesian Mobile Operators — An Overview

If you want to top up mobile credit for someone in Indonesia from abroad, you need to know which operator they are on. Each operator runs a separate system — credit cannot be transferred between networks.

How to Find Out Which Operator Someone Is On
Not sure which network your family member uses? Here are a few easy ways to find out:
- Dial *#06# — This code displays device information including the active SIM. Some phones also show the operator name.
- Check the status bar — The operator name is usually displayed in the top corner of the phone's screen.
- Check the SIM card — Open the SIM tray and look at the logo or name printed on the card.
- Check the number prefix — Every operator uses specific number prefixes. For example: 0812, 0813, 0821–0823 are Telkomsel; 0815–0816, 0855–0858 are Indosat; 0817–0818, 0859, 0877–0878 are XL; 0881–0889 are Smartfren; 0895–0899 are Three.
