eSIMplus eSIM Data Plans for Guam

eSIMplus does not provide an unlimited‑data eSIM for Guam. Instead, the provider sells fixed‑data plans. A 30‑day plan gives 30GB for $91.42 USD, while a smaller 20GB 30‑day plan costs $65.76 USD. For travelers who need less data, there are 10GB plans available for 30 days at $35.50 USD or for 15 days at $32.43 USD, and a 5GB 7‑day option for $17.62 USD. Choosing a fixed data plan can be more cost‑effective unless the user is an extremely heavy data consumer.

eSIMplus does not provide Guam eSIMs that include a phone number or SMS capability. The available Guam plans are data‑only, allowing you to connect to Wi‑Fi or mobile data without a local voice or text service.

Because there is no phone number or SMS support, travelers can still make calls and send messages using internet‑based apps such as WhatsApp, Telegram, or iMessage. These VoIP services operate over the data connection and provide a convenient alternative to traditional telephony.

eSIMplus offers 11 multi‑country data plans for Guam. All of these plans are fixed data‑amount offerings, not daily data‑cap plans. Prices range from about $5.91 to $92.06, and data caps span 1 GB to 30 GB. Validity periods vary from 5 to 30 days.
