FullBars is built on two ideas: no roaming rip-offs and no setup faff. Buy a plan in seconds, tap to install, and land connected in 190+ countries. Plans start at £1, top-ups land on the same eSIM and there's a human on support if anything goes wrong.
FullBars does not provide an unlimited data eSIM for Guam. Travelers who need data in Guam can instead choose from Fixed data plans, such as a 20GB plan for 30 days at $88.60 USD, a 10GB plan for 30 days at $48.32 USD, a 5GB plan for 30 days at $24.15 USD, a 3GB plan for 15 days at $14.76 USD, or a 1GB plan for 7 days at $5.36 USD.
Selecting a Fixed data plan can be more cost‑effective for most users, unless a traveler expects to use a very high volume of data that would far exceed the allowances of the available plans.
FullBars does not provide Guam eSIM plans that include a local phone number or SMS capability. Travelers who need a phone number or standard SMS service will need to use data-only plans and rely on VoIP applications such as WhatsApp, Telegram, or iMessage for voice and text communication. However, some destinations may block or restrict certain VoIP services, so travelers should verify that the apps they rely on are accessible in Guam before purchasing a data plan.
FullBars provides five single‑country data plans for Guam and does not offer any multi‑country solutions there. The available plans range in price from $5.36 to $88.60 and offer between 1 GB and 20 GB of data, with validity periods spanning 7 to 30 days.
