Can I get a travel eSIM with a phone number and SMS for Guam?

Yes, several travel eSIM plans that include a phone number and SMS are available for Guam. Providers such as Airalo (Håfa Adai Unlimited), GlobaleSIM (Guam), Airhub (Guam Unlimited 4 days and 8 days), eSimfly (Orange World 20 GB 30 days), Orange Travel (World Zone 6), and Roamify (Guam eSIM Unlimited Data, Call and SMS) offer these plans. All of these plans give you a local Guam phone number with the dialing code +1‑671 or +1 and support inbound and outbound voice calls, while most also allow both inbound and outbound SMS; the eSimfly and Orange Travel plans use the French dialing code +33 and therefore provide foreign numbers rather than local Guam numbers.

Prices for the Guam eSIMs start at $8.00 USD for a 3‑day Airalo plan and rise to around $85.00 USD for a 30‑day GlobaleSIM plan, with validity periods ranging from 3 days up to 30 days. Travelers looking for the lowest‑cost local‑number option can choose a 3‑day Airalo Håfa Adai Unlimited plan, whereas those requiring longer coverage may opt for a 30‑day GlobaleSIM or Roamify plan. All listed options provide inbound and outbound voice support; SMS support varies, but most plans support both inbound and outbound messages.
