SeferESIM eSIM Data Plans for Guam

SeferESIM does not offer a plan with unlimited data for Guam. Travelers can choose from fixed‑data options, such as the Guam 20GB 30Days plan for $83.08 USD or the Guam 10GB/Day plan for $39.00 USD, which provide 20 GB and 10 GB of data respectively over a set validity period. These choices may be more cost‑effective for most users, while heavy data consumers can purchase additional credit using a Pay‑as‑you‑go feature if needed.

SeferESIM does not provide a Guam eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for Guam, so travelers will not receive a local number or the ability to send or receive text messages directly from the eSIM.

Travelers who need voice or messaging can use VoIP applications 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 available in Guam before purchasing a plan.

SeferESIM offers 42 single‑country plans for Guam. In addition, there are 17 multi‑country plans that include Guam. The available plans span a price range from $4.98 to $959.40 and provide data caps between 500 MB and 20 GB. Some plans feature a fixed data amount, while others offer a daily data cap, giving travelers flexibility based on their usage patterns.
