SimSmash eSIM Data Plans for Montserrat

SimSmash does not provide a true unlimited data eSIM for Montserrat. The plans that contain “Unlimited” in their names feature fixed data caps—490 MB, 1 GB, 2 GB, or 5 GB—valid for just 1 day each, after which the speed is reduced. For travelers who need higher data allowances, SimSmash offers fixed data plans such as 20 GB for 30 days or 10 GB for 30 days, which can be more cost‑effective for moderate to heavy data use.

SimSmash does not offer Montserrat eSIM plans that include a phone number or SMS capability; only data‑only eSIM plans are available from this provider.

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 these services, so it is advisable to verify that the apps you rely on are accessible in Montserrat before purchasing a plan.

SimSmash provides eight single‑country data plans that cover Montserrat, while there are no multi‑country plans that include Montserrat. The price range for these plans falls between $3.99 and $95.99, and the data caps vary from 490 MB up to 20 GB. Most of the plans are fixed‑data offerings, meaning you receive a set amount of data for the duration of the validity period, which is between one and thirty days. Some plans also allow tethering, enabling the use of the data connection on multiple devices.
