ByteSIM eSIM Data Plans for Guam

ByteSIM does not provide a truly unlimited data plan for Guam. The plans that carry the “Unlimited” label are limited to 1 GB per day and come with a reduced speed of 10240 kbps after that daily allotment is reached. For travelers who need more data, ByteSIM offers fixed‑data options, such as a 20 GB plan valid for 3 days at $58.90 USD or a 20 GB plan valid for 7 days at $67.90 USD. Choosing one of these fixed plans can be more cost effective for heavy data usage.

ByteSIM does not provide a Guam eSIM that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for Guam, so users cannot receive or send text messages or place standard voice calls directly through a local number. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging without a phone number or SMS support.

ByteSIM currently offers 46 single coverage data plans for Guam. These plans provide a fixed data allowance ranging from 500MB to 20GB, with validity periods from 1 to 30 days. Additionally, 16 of these plans feature a daily data cap, while the remaining 30 offer a fixed data amount. Prices for these plans range from $3.90 to $99.90. ByteSIM does not currently offer any multi-country plans that include Guam.
