Comprehensive Guide Before Buying a Prepaid SIM Card in Indonesia

Indonesia's Telkomsel SIM Card Guide for Foreigners

Telksomel Network is the most prominent phone provider in Indonesia. In this blog post, I'll share everything you need to know about this mobile provider, with tips for Telksomsel prepaid SIM cards and postpaid.

Before living in Bali for almost two years, I visited Bali every year for a holiday. I always opted to get a Telksomel SIM card because it was very reliable, even when I went to smaller islands in Lombok or remote places around Bali. 

Which SIM card works best in Indonesia?

From my experience, coverage-wise, Telkosmel is still the best SIM card in Indonesia. Apart from offering 5G network, they are also a very reliable network that even works in Indonesia's small villages and remote islands.

If you work remotely or are traveling around Indonesia and must be constantly connected to mobile data. In that case, Telksomsel is the best option for staying connected and is very reliable even during rainy seasons. 

Other SIM card providers offering cheaper airport options are XL Xiata and Indosat. Next to Telksomsel, these are the second-best mobile providers in Indonesia, and they have more affordable plans for calls and texts that cater more to locals in Indonesia.

How long does a Telkomsel SIM card last?

In Indonesia, tourist SIM cards have many different data plans, which I will share in another section of this article, as well as a comparison of the prices you'll get from the airport.

For Telksomsel tourist SIM cards, the average activation time is 30–90 days. If you don't top-up your SIM of any amount after 30 days you will get a notification on when it will expire. I suggest you download the Telksomsel app so you can view the value of the credit you still have the gigabytes of the data as well.

You can choose data plans that could last for one day, one week, 14 days, or monthly, depending on your needs during your stay in Indonesia. 

Depending on the length of stay, I suggest how you top-up your credit. For my case I always get the lowest data since I don't really use call and text and most accommodations and cafes around in Indonesia have decent wifi connections.

How do I activate my Telksomsel SIM card?

After you buy your SIM card, whether you get it from the airport, phone shop, or Telksomsel office, you need to insert it and register your phone; you need to give your phone's IMEI as the owner of the sim as part of Indonesia's rule. The staff or cashier will borrow a copy of your passport and register it for you. 

You can also buy a Telksomel SIM card online but you will need to pick this up at the branch you selected.

Testing and checking if the new SIM card is compatible with your phone is better before leaving the kiosk and trying the data. This way, you can verify that the SIM card has been activated and won't have to be returned if it doesn't work.

If you are unsure of how long to stay in Indonesia and don't want to keep changing your tourist sim card every 90 days, please register your phone's IMEI upon arrival at the airport. 

How do I top-up my Telkomsel prepaid sim card?

Adding a credit or topping up your Telksomel prepaid SIM card is easy. Just go to any convenience store that you will find in every corner of Indonesia. For a top-up, you can also go to Indomaret, Alfamart, or Circle K.

I've never tried purchasing any credit top-ups or using my credit card, so always bring cash with you when going to the convenience stores. 

It's still best to go to a convenience store so the teller/cashier can help you with your credit top-up. In my case, I usually ask for help from my Indonesian friends who have postpaid Telksomsel or Indonesian local banks to top up my credit and give them cash. 

Local Indonesian bank apps can top-up credit for Telksomel SIM cards, and this is the easier way, especially if you have local friends who can help you. 

What Are The Telkomsel Prepaid Plans?

Telksomel Prepaid plans don't have to be unlimited data, call, and text plans. So, always choose depending on the length of your stay and how much data you need. Most cafes and even local warungs in Bali always offer free and fast Wi-Fi, so staying connected is straightforward.
