Monty eSIM eSIM Data Plans for Guam

Monty eSIM does not provide an unlimited data eSIM for Guam. The available options are fixed‑data plans that deliver 10GB, 5GB, or 3GB of high‑speed data for a 30‑day validity period. For instance, the 10GB plan is priced at $54.50 USD, the 5GB plan at $29.50 USD, and the 3GB plan at $17.99 USD. Fixed data plans can be more cost‑effective for most travelers unless a user needs a very high volume of data that exceeds the largest fixed allowance.

Monty eSIM does not offer a Guam eSIM that includes a phone number or SMS capability. The provider only supplies data‑only eSIM plans for Guam, so travelers will not receive a local number for calls or text messages.

Because the plan delivers only internet access, users can still communicate through data‑based services. VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and provide voice and messaging features without needing a traditional phone number.

Monty eSIM provides four single‑country plans for Guam, and four multi‑country plans that include Guam. The plans range in data allowance from 1 GB up to 10 GB and in price from $7.50 to $66.50, with validity periods between 7 and 30 days.
