What You Get and What You Don’t
When you buy a Telkomsel eSIM from Alt eSIM, you are purchasing a travel eSIM that roams onto the Telkomsel network in Indonesia. This means you are not buying Telkomsel’s own SIM, eSIM, plan, or contract. Our eSIM allows you to use data in Indonesia with ease, but it is not an official Telkomsel product. You will not get access to Telkomsel’s customer service or any of their exclusive offers. Instead, you will receive data connectivity through our service, which operates on a pay-as-you-go basis with no long-term commitments.
Applicable Destinations
Our Telkomsel eSIM is designed for use in Indonesia. When you arrive in Indonesia, our eSIM will automatically connect to the Telkomsel network, allowing you to use data services. This eSIM is perfect for travelers who are visiting Indonesia and need reliable data access. It is important to note that this eSIM will not work in any other country, as it is specifically configured for Indonesia. If you are traveling to multiple destinations, you may need to purchase additional eSIMs for each country.
Choosing the Right Plan Shape
When selecting a plan, you have two main options: daily plans and total data plans. Daily plans are ideal for travelers who need consistent data access throughout their trip, with options for 1GB, 2GB, or 3GB per day. On the other hand, total data plans are better for those who want to manage their data usage over the entire trip, with choices ranging from 1GB to 50GB. Daily plans work out from US$0.92 per day, making them a cost-effective choice for many travelers. However, if you are a heavy data user, a total data plan might be more suitable.
How Getting Connected Works
To get connected, you need to install the eSIM on your device. This process is straightforward and can be done through a QR code provided by Alt eSIM. Once installed, your device will automatically connect to the Telkomsel network when you arrive in Indonesia. You do not need to manually select the network or enter any additional information. The connection is seamless and you will be able to use data immediately. However, it is important to ensure that your device is compatible with eSIM technology before purchasing.
What Happens When the Allowance Runs Out
Once your data allowance is used up, your connection speed will drop to 128 or 384 kbps, depending on the plan. This speed is still usable for basic tasks such as browsing, email, and messaging, but it may be too slow for streaming or downloading large files. If you need more data, you can purchase an additional plan at any time. This flexibility allows you to manage your data usage and avoid unexpected charges. However, it is important to monitor your usage to ensure you do not run out of data at a critical moment.
