Monty eSIM eSIM Data Plans for Guam

Monty eSIM does not provide an unlimited data eSIM for Guam. All available plans are fixed‑data packages, the largest of which offers 10GB for 30 days at $45.99 USD. A smaller 5GB option is also available for 30 days at $25.99 USD. Choosing a fixed data plan can be more economical for most travelers, unless extremely heavy data usage justifies a different provider or additional data add‑ons.

Monty eSIM does not provide a Guam eSIM that includes a local phone number or SMS capability. Only data‑only plans are offered for Guam, so travelers must rely on VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

Monty eSIM offers 10 single‑country data plans that include Guam, and 4 multi‑country plans that cover Guam. The single‑country plans range in price from about $5.99 to $112.15 and in data cap from 1 GB to 10 GB, with validity periods of 1 to 30 days. The multi‑country plans have a similar price and data cap range. Monty provides both daily‑data‑cap and fixed‑data‑cap options. Daily‑cap plans limit the amount of data that can be used each day, while fixed‑cap plans allow the full data allotment to be consumed at any time during the validity period. In summary, Guam‑specific plans range from a modest 1 GB at roughly $6 to a 10 GB plan above $100, with both single‑ and multi‑country options available.
