Travelers can purchase a travel eSIM with a phone number and SMS for Guam from Airalo and Roamify. Airaloâs HĂ„fa Adai Unlimited eSIMs use a local Guam dialing code +1â671, providing inbound and outbound voice and SMS with unlimited data. The plans are available for 3âday, 7âday, 10âday, 15âday (2GB/day), 30âday (unlimited data) and 30âday (2GB/day) validity, with prices ranging from $8.00 to $62.00. Roamify offers Guam eSIM Unlimited Data, Call and SMS plans that use a general US dialing code +1, valid for 15 or 30 days, priced from $45.00 to $55.00, and also support inbound and outbound voice and SMS. Because Airaloâs numbers match Guamâs local dialing code, they are truly local numbers, whereas Roamifyâs numbers are not specific to Guam and may appear as mainland US numbers. Both providers enable voice and SMS directly on the eSIM, providing an alternative to using VoIP applications for messaging.
