The Cheapest Way to Call International Numbers from Indonesia Using Telkomsel

If you want to call international numbers from Indonesia using Telkomsel in the most cost-effective way, there’s a smarter option than regular international dialing: Telkomsel SLI/IDD (International Direct Dialing).

Telkomsel offers two main SLI options:

• SLI 007

Each has different pricing rules, time limits, and use cases. Below is a complete breakdown so you can choose the best option for your needs.
