Cellesim eSIM Data Plans for Guam

Cellesim does not provide an unlimited data eSIM for Guam. The available options are fixed data plans that must be used within a set validity period. Examples include the Guam 20GB 30d plan, the Guam 10GB 30d plan, the Guam 5GB 30d plan, the Guam 3GB 15d plan, and the Guam 3GB 30d plan. These plans offer a specific data allowance and a defined validity window, and they include tethering where noted. Choosing a fixed data plan can be more cost‑effective for most travelers unless they require truly unlimited data usage.

Cellexim does not offer a Guam eSIM that includes a phone number or the ability to send or receive SMS. The provider only sells data‑only eSIM plans for Guam, so travelers will not receive a local or international number with voice or text messaging.

Travelers who need to communicate while in Guam can still use popular VoIP services such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are accessible in Guam before purchasing a data‑only plan.

Cellesim provides 11 single‑country data plans for Guam and does not offer any multi‑country plans. The plans range in price from about $8.70 to $149.40 and in data from 1 GB to 20 GB. Five of the plans use a daily data cap, where the data allowance resets each day, while six use a fixed data cap that lasts for the full validity period of the plan. This gives travellers a range of options, from short burst usage to longer‑term data needs, all within the stated price and data ranges.
