SimBalkan eSIM Data Plans for Japan

SimBalkan does not provide a truly unlimited data eSIM for Japan. The plans labeled “Unlimited” in the provider’s catalogue actually give only 1 GB of high‑speed data per day or a single 1 GB burst, after which the speed is reduced.

For travellers looking for larger data allowances, SimBalkan offers fixed‑data plans. For example, a 50 GB plan that is valid for 30 days costs $23.07, while a 20 GB plan for 30 days is priced at $11.48. These fixed‑data plans can be more economical for most users, unless the traveller is an exceptionally heavy data consumer.

SimBalkan does not offer an eSIM for Japan that includes a phone number or SMS capability. Travelers can purchase only data‑only plans from SimBalkan for use in Japan. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although it is advisable to confirm that these services are accessible in Japan before buying a plan.

SimBalkan offers 17 single‑country plans that cover Japan alone and 5 multi‑country plans that include Japan within a broader coverage radius. The single‑country plans generally come in fixed data amounts ranging from 100 MB up to 50 GB, while the multi‑country options often provide a daily data cap—typical daily limits of 1 GB or less—allowing users to spread usage across several destinations. Prices for all plans span from roughly $1 04 to $52 02 USD, giving a broad spectrum of affordability across the different data caps.
