Instabridge does not provide an unlimited data eSIM for Russia. The available options are fixed data plans that grant a specified amount of high‑speed data for a set number of days, such as the 20GB plan valid for 7 days and the 10GB plan valid for 30 days. These bundles offer large data allowances that may be cost‑effective for most travelers, but they include a hard cap and a fixed validity period. If a traveler requires more data, they can purchase additional fixed plans or a Pay‑as‑you‑go plan, which allows unlimited usage until the data credit is exhausted.
