This CoreESIM plan is specifically provisioned for network access exclusively within Guam. Saipan and the broader Northern Mariana Islands (CNMI) constitute a separate territorial jurisdiction with distinct mobile network agreements. Therefore, this eSIM will not provide connectivity in Saipan or other CNMI islands. For travelers planning to visit both Guam and the CNMI, CoreESIM recommends a separate regional eSIM or a dedicated plan that explicitly covers both territories.
HELP CENTER
Is this CoreESIM Guam plan also valid for Saipan and the Northern Mariana Islands (CNMI)?
