SIMzip eSIM Data Plans for Guam

SIMzip does not provide an unlimited data eSIM for Guam. The available options are fixed‑data plans, such as the 5GB for 10 days plan and the 3GB for 5 days plan, each of which includes tethering on 4G and 5G networks. For travelers who need a large amount of data, these fixed plans can be a cost‑effective choice unless very heavy data usage is expected, in which case an unlimited plan from another provider might be more appropriate.

SIMzip does not provide a Guam eSIM plan that includes a phone number or SMS capability. The provider’s Guam catalog consists solely of data‑only eSIM offerings, so travelers cannot receive or make traditional voice calls or send text messages directly to or from a Guam phone number via SIMzip.

Travelers who need to stay connected for voice and messaging purposes can use internet‑based VoIP services such as WhatsApp, Telegram, or iMessage over the data connection provided by the SIMzip eSIM plan. These applications work through data and do not require a local phone number or SMS functionality.

SIMzip currently offers four single-coverage data plans for Guam. These plans provide data allowances ranging from 1GB to 5GB and are valid for 5 to 10 days. Prices for these plans range from $64.00 to $176.00. There are currently no multi-country plans available from SIMzip that include Guam. Tethering is permitted with some of the available plans.
