WonderConnect does not provide an unlimited data eSIM for Guam. The plans listed for Guam have fixed data caps, the largest of which is 20GB for 30 days. Travelers who need a larger allowance can choose from the fixed data plans available, such as the 20GB at $75.99 USD or the 10GB at $44.99 USD, both of which are valid for 30 days and support 5G connectivity. Fixed data plans may offer a more cost‑effective option unless very heavy data usage is expected.
