eSIMCard eSIM Data Plans for Guam

eSIMCard does not provide a truly unlimited data eSIM for Guam. The plans with “Unlimited” in the name are actually capped at 1 GB per day (or 2 GB per day for the “Unlimited Plus” variants) and after that limit is reached the speed is reduced to 500 kbps or 2000 kbps. Those plans offer a short‑term high‑speed data allowance rather than an uncapped experience.

Instead, eSIMCard offers fixed‑data plans that give higher volumes of high‑speed data up to full speed. Examples include the 20GB plan for 30 days priced at $98.24 USD, the 10GB plan for 30 days at $54.95 USD, and the 5GB plan for 30 days at $30.20 USD. These plans provide a larger amount of data without the speed throttling that follows the “Unlimited” limits.

eSIMCard does not provide a Guam eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Guam, so travelers must rely on data‑based VoIP applications such as WhatsApp, Telegram, or iMessage for voice and messaging.

eSIMCard currently offers 18 single coverage data plans specifically for Guam. Additionally, they provide 5 multi-country plans that include Guam as part of their coverage. These plans vary, with options for both fixed data amounts (up to 20GB) and daily data caps. Prices range from approximately $7.22 to $320.19, and plans are valid for 1 to 30 days. Some plans also include features like tethering, with potential speed reductions after certain data usage thresholds (500 or 2000 units).
