eSIM.sm does not provide an unlimited data eSIM for Mongolia. Instead the retailer sells fixed data plans that range from 1GB to 10GB. For example, a 10GB 30 days plan is available for $75.50 USD, and a 5GB 15 days plan is priced at $40.10 USD. Both plans include tethering and cover the entire Mongolian territory.
If a travelerโs data usage stays within these fixed allowances, choosing a fixed data plan is often more costโeffective than paying for an unlimited option that is not offered. Only visitors with extremely heavy data consumption might consider alternative providers that offer unlimited plans.
