Reviews: Guam & Saipan 5G eSIM | Daily/Total Data Package | 1–30 days | Calendar Day Billing | QR Code

Using an eSIM in Saipan was so convenient! I bought a data plan in the app within minutes before departure, and the moment the plane landed, I was instantly connected to the 5G network. The internet speed was super fast, and navigation, uploading videos, and checking travel guides were all smooth sailing. The price was also more affordable than buying a physical SIM card locally. No need to change SIM cards or find a SIM card ejector tool; everything is done with just your phone—effortless and smart. I highly recommend it to all independent travelers!

Ease to install and no issue use, a good choice to travel without physical card but no phone number as some place ordering food require insert phone number.
