Under the regulation, phones with international mobile equipment identity (IMEI) — a unique code assigned to every SIM card slot a phone has — that have not been registered in Indonesia will not be able to connect to any of the country’s cellular services.
The Ministry of Industries, one of the initiators of the regulation, has launched a page where users can enter their phone’s IMEI to see if it’s registered in the government’s database of legally approved phones.
You can view the page here.
Your phone’s IMEI should be available in the about section of its settings. Alternatively, you can dial *#06# to automatically bring up your phone’s IMEI.
What to do if it’s not registered?
If you register device at airport within 24 hours of arrival you don’t pay customs tax on devices less than the value of US$500. Anything above that you have to pay 40% tax.
If it’s more than 24 hours after you arrive you pay 40% tax regardless of the value of device. In this case you have to register your mobile device at the tax office
- boarding pass or flight ticket
- IMEI number
