No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

Travelers to Guam often assume their standard U.S. mobile plans (from carriers like AT&T, T-Mobile, or Verizon) will include it as a domestic territory. However, this is frequently not the case. Many U.S. plans either exclude Guam entirely, charge exorbitant international roaming fees (e.g., $3+/MB), or throttle data speeds to unusable levels. WorldESIM offers dedicated plans for Guam, providing reliable 4G/LTE/5G connectivity at transparent, competitive rates, ensuring you stay connected without unexpected charges.

These partnerships guarantee you access to robust 4G/LTE (and often 5G) coverage, whether you're in Hagåtña, exploring the beaches, or navigating the island, ensuring seamless communication and internet access throughout your stay.
