★★★★★ The setup was very easy, and I was able to use the internet immediately upon arrival. Using sightseeing and restaurant searches, as well as map apps, was very convenient. I had no complaints about the communication environment during my trip and am extremely satisfied.

Reviews: Saipan/Guam 5G/4G eSIM | Daily Package/Data Package | 24-Hour Billing | 1-30 Days | QR Code

I added the eSIM before departure, but when I tried to activate it upon arrival, it wouldn't connect properly, which made me panic for a moment. Upon checking, I found that the APN was somehow set to the name of my current carrier. After manually changing it, it worked perfectly. From then on, I was able to use the internet without any problems until the day I returned home, which was very convenient! Ultimately, I'm very satisfied!

I travel frequently between Arab countries and it was very convenient for me to not have to change my SIM card often. I recommend it to everyone.

The connection was good, and since I installed it in advance, I was able to use it immediately upon arriving in Guam. I was assigned a local number, so I was able to make calls conveniently while there.
