TooSim eSIM Data Plans for Montenegro

TooSim does not provide an unlimited data eSIM for Montenegro. The available plans are fixed data bundles, such as the 20GB plan valid for 30 days and the 10GB plan also valid for 30 days. These fixed data plans give a clear data allowance that must be used within the specified validity period. Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a pay‑as‑you‑go model.

TooSim does not provide eSIM plans for Montenegro that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Montenegro before purchasing a plan.

TooSim offers six single‑country eSIM data plans in Montenegro, with no multi‑country plans available. The plans range in price from $11.99 to $102.99 and in data cap from 1 GB to 20 GB, each valid for 7 to 30 days. Tethering is allowed on some of the plans.
