ByteSIM does not offer a plan that provides truly unlimited high‑speed data in Guam. All of the packages that use the name “Unlimited” are actually capped at 1 GB per day; after that limit the speed is throttled to 10240 kbps. For travelers who need a larger data allowance, ByteSIM provides fixed‑data options. For example, a 20 GB plan is available for 3 days, 5 days, 7 days, 10 days or 15 days, all with tethering allowed and no reduction in speed. Choosing one of these fixed plans can be a more economical choice for most users who require a lot of data but are not extremely heavy consumers.
