eSIMCard does not provide a truly unlimited data eSIM for Guam. The plans that carry โUnlimitedโ in their name are capped at 1GB per day or 2GB per day, and once the allocated data is used the speed drops to 500kbps or 2000kbps, respectively.
For travelers who need more data without the throttling, eSIMCard offers fixedโdata plans. Examples include a 20GB eSIM for 30 days priced at $98.24 USD, a 10GB eSIM for 30 days at $54.95 USD, a 5GB eSIM for 30 days for $30.20 USD, a 3GB eSIM for 30 days for $18.53 USD, and a 2GB eSIM for 15 days for $13.40 USD. These fixedโdata options are typically more cost effective for users who expect to consume more than a few gigabytes during their stay in Guam.
