Case Study: Comparing Roaming Costs vs. Local SIM

Let’s consider a traveler, Ani, who is visiting Singapore for 5 days. She needs data for navigation, social media, and occasional work emails. Her options are:

• Option 1: Telkomsel Roaming Package: 5-day package with 5GB data costs rp 150,000.
• Option 2: Singapore Local SIM: Tourist SIM with 10GB data and local calls costs SGD 20 (approximately Rp 230,000).

In this case, the Telkomsel roaming package is significantly cheaper. However, if Ani needs more than 5GB of data or makes a lot of local calls, the Singapore local SIM might be the better choice.

First-Hand Experience: My Roaming Adventure in Japan

I recently traveled to Japan and decided to use my Indosat Ooredoo Hutchison (Tri) SIM for roaming. I opted for their weekly data package,which provided a decent amount of data at a reasonable price. The network connectivity was excellent in Tokyo and Osaka, allowing me to easily navigate using Google Maps and stay connected with friends and family. While roaming was convenient, I noticed that data speeds were occasionally slower compared to what I experience in indonesia. One lesson learned: always check your APN settings to ensure they are correct for the roaming network.
