eSIMCard eSIM Data Plans for Guam

eSIMCard does not provide a truly unlimited data eSIM for Guam. The plans that carry “Unlimited” in their name are capped at 1GB per day or 2GB per day, and once the allocated data is used the speed drops to 500kbps or 2000kbps, respectively.

For travelers who need more data without the throttling, eSIMCard offers fixed‑data plans. Examples include a 20GB eSIM for 30 days priced at $98.24 USD, a 10GB eSIM for 30 days at $54.95 USD, a 5GB eSIM for 30 days for $30.20 USD, a 3GB eSIM for 30 days for $18.53 USD, and a 2GB eSIM for 15 days for $13.40 USD. These fixed‑data options are typically more cost effective for users who expect to consume more than a few gigabytes during their stay in Guam.

eSIMCard does not provide a Guam eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for the destination, so travelers will not receive an active phone line or the ability to send or receive standard text messages directly on the SIM.

Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. These services function without a traditional phone number or SMS support, allowing communication while traveling in Guam.

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).
