It’s ideal for travelers who want to stay reachable via their primary number while using local data services in Indonesia.

12. What is a travel eSIM, and how does it work in Indonesia?

14. Is an eSIM cheaper than international roaming in Indonesia?
Yes. Indonesia eSIM plans are priced like local SIMs, offering fast internet without hidden fees. Roaming can be expensive with overage charges. eSIMs are prepaid, fully digital, and provide predictable costs.

15. What’s the difference between an Indonesia eSIM and a physical SIM card?
An Indonesia eSIM is fully digital, purchased and activated online, with no store visits or ID checks. Physical SIMs require in-person purchase, hardware installation, and verification. eSIMs support dual SIM functionality, allowing home SIM and local data simultaneously. Installation takes minutes, is hassle-free, and provides flexible plans, reliable networks, and instant connectivity across Indonesia.
16. Can I use an Indonesia eSIM and my regular SIM at the same time?
Yes, most modern smartphones support dual SIM functionality, with one physical SIM and one eSIM. You can keep your home SIM active for calls or SMS while using the Indonesia eSIM exclusively for mobile data. This ensures you stay reachable on your primary number while enjoying local internet at local rates. Simply go to your SIM settings and assign the Indonesia eSIM for data, while your home SIM handles calls. Dual SIM management is seamless, convenient for travelers, and allows instant switching between networks, whether in Jakarta, Bali, or remote Indonesian islands.
17. Will I get a new phone number with an Indonesia eSIM?
Most Indonesia eSIMs purchased via Mobimatter are data-only, so they typically do not provide a new phone number for calls or SMS. Your home SIM continues to handle voice and messaging if dual SIM is supported. Data apps like WhatsApp, iMessage, and Telegram function normally over the eSIM. If voice or SMS is essential, some plans offer VoIP support or optional voice bundles. Always check the plan features before purchase. For most travelers, data access is sufficient for navigation, communication, and streaming without needing a new Indonesian phone number.
18. Can I still receive calls and texts on my original number while using an Indonesia eSIM for data?
Yes, provided your phone supports dual SIM functionality. Assign the Indonesia eSIM for data only and keep your home SIM active for voice and SMS. Make sure data roaming on your home SIM is turned off to avoid charges. This setup allows you to stay reachable by family, colleagues, or business contacts while using local Indonesian networks for high-speed internet. Mobimatter provides clear instructions to configure this correctly, ensuring you won’t incur unexpected fees while staying connected on both your home and Indonesia eSIM simultaneously.
19. Do Indonesia travel eSIMs include calls and SMS, or are they data-only?
Most Indonesia eSIMs sold via Mobimatter are data-only, meaning they do not include traditional voice calling or SMS services. Data-based apps such as WhatsApp, Skype, Google Meet, or FaceTime Audio work perfectly. A few plans may provide optional voice/SMS bundles, but these are rare. For general travel needs—maps, messaging, ride-hailing apps, and video calls—a data-only eSIM is sufficient. Always review the plan description before purchase. Using a data-only eSIM is ideal for travelers seeking fast internet and cost-effective solutions while avoiding roaming charges.
20. How much data will I need for my trip to Indonesia?
Data requirements vary by travel habits. Light travelers using navigation, messaging apps, or emails may need 3–5 GB. Moderate users browsing social media and streaming music should consider 10–20 GB. Heavy users uploading content, attending video calls, or streaming videos may require 30 GB or more. Mobimatter offers a variety of plans so you can match data volume to your usage. Monitor usage through your phone settings or apps. It is better to buy slightly more than needed to avoid throttling or topping up frequently. Proper planning ensures smooth internet access across Indonesia.
21. Is my phone unlocked and compatible with Indonesia eSIMs?
To use an Indonesia eSIM, your phone must be unlocked and eSIM-compatible. Most flagship phones released after 2020 meet these criteria.
