Simsima eSIM Data Plans for Mongolia

Simsima does not provide a truly unlimited data eSIM for Mongolia. The plans titled “Unlimited – 7 days, ” “Unlimited – 10 days, ” and “Unlimited – 30 days” actually grant 3 GB of high‑speed data each day. After that daily limit the speed is throttled to 1000 kbps.

Travelers who need a fixed data allowance can choose from Simsima’s other plans. For example, a 20 GB plan is available for 30 days at $27.27 USD, a 10 GB plan for 30 days costs $26.75 USD, and a 5 GB plan for 30 days is priced at $17.49 USD. These fixed‑data plans are usually more cost effective unless the user is an extremely heavy data consumer.

Simsima does not provide an eSIM plan for Mongolia that includes a phone number or SMS capability. The provider offers only data‑only eSIMs in this destination.

Travelers who need voice or text communication can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to verify that the apps required for your communication needs are accessible in Mongolia before purchasing a plan.

Simsima provides 9 single‑country data plans and 9 multi‑country data plans for use in Mongolia. Within those offerings there are four plans that allow a daily data cap and fourteen that feature a fixed data amount, offering both time‑limited daily limits and a set data quantity. The available options span a price range from roughly $5.40 to $131.48 and a data cap range of 1 GB to 20 GB, with validity periods that can last from five to one hundred and eighty days.
