Monty eSIM eSIM Data Plans for Guam

Monty eSIM does not provide an unlimited data eSIM for Guam. The available Guam‑specific plans include fixed data amounts: a 10GB plan, a 5GB plan, and a 3GB plan, each valid for 30 days.

For travelers who prefer larger data allowances, Monty eSIM offers a 10GB plan for $66.50 USD and a 5GB plan for $41.99 USD. Fixed data plans may be more cost‑effective for most users, unless a traveler requires very high data consumption.

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 offers three single‑country plans that cover Guam and four multi‑country plans that include Guam. Prices for the various packages range from about $9.99 to $66.50, while the data caps fall between 1 GB and 10 GB. Each plan is valid for 7 to 30 days.
