eSIM.sm does not provide an unlimited data eSIM for Guam. All plans listed for Guam offer fixed data allowances, ranging from 1GB for 7 days to 10GB for 30 days, and each includes tethering. Because there are no unlimited options, users who need more data may consider purchasing a larger fixedโdata plan. For example, the 10GB 30โday plan is the biggest available and could be a more economical choice for highโusage travelers, while lighter users might find the 5GB 30โday or 3GB 15โday plans sufficient. Choosing a fixed plan can provide predictable cost control unless the traveler is an extremely heavy data consumer.
