Simology eSIM Data Plans for Guam

Simology’s eSIM plans for Guam do not include a truly unlimited data option. The plans that carry the “Unlimited” label actually allocate 1GB of high‑speed data each day; after the daily limit is reached the speed is throttled to 1000kbps and the data rate continues at 1Mbps. Because the data cap is a hard limit of 1GB per day, the plans are fixed data plans rather than unrestricted data bundles.

If a traveler wishes more data, Simology offers several fixed data plans on a 30‑day validity period. Examples include the eSIM GU, 50 GB, 30 days at $227.22 USD, the eSIM GU, 20 GB, 30 days at $89.26 USD, the eSIM GU, 10 GB, 30 days at $63.75 USD, the eSIM GU, 5 GB, 30 days at $33.61 USD, and the eSIM GU, 3 GB, 30 days at $25.49 USD. These packages provide larger data allowances without the reduced speed that applies after the daily 1 GB limit of the “Unlimited” plans.

Simology does not provide a Guam eSIM that includes a local phone number or SMS capability. All eSIM options from Simology for Guam are data‑only. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but should verify that these services are accessible in Guam before purchasing.

Simology offers 13 single‑country data plans for Guam, with no multi‑country options available. The plans are split into fixed data amount packages and daily data cap packages, where the former provides a set amount of data for the full validity period and the latter resets each day within the validity window. Prices range from roughly $9.26 to $227.22, while data caps vary from 1 GB to 50 GB over validity periods of 3 to 30 days.
