Prepaid SIM Cards in Indonesia: What to Expect

Indonesia requires foreigners to register their IMEI, a step many travelers discover the hard way.

• Tourist SIMs cost roughly $7 to $10 for 25 GB
• Telkomsel has the best coverage across islands
• Registration needs your passport and IMEI number
• Phones used longer than 90 days need IMEI registration

Register at an official Telkomsel store or airport counter to keep your phone working the whole trip.

IMEI registration is free but time-consuming, so budget an extra 15 minutes at an official store.
