Ubigi eSIM Data Plans for Guam

Ubigi does not offer an unlimited data eSIM for Guam. The plans available from Ubigi in Guam provide fixed data allowances. For example, the WORLD plan offers 60GB per month for 30 days, the 50GB plan lasts 180 days, the 25GB plan lasts 90 days, the 20GB per month plan lasts 30 days, and a 10GB plan also lasts 30 days.
