My First World eSIM
What is an eSIM?
This service enables users to establish profile information on the SIM card integrated into their smartphones, facilitating Internet connectivity across different countries and regions. Unlike WiFi devices that require constant portability, smartphones equipped with this service offer a smarter solution for Internet access.
Please note that this service is not available except SIM-free or SIM-unlocked eSIM compatible smartphones.
Which one should I purchase?
First of all, choose the country or region where you intend to utilize the service.
Then, proceed to the purchase page where you can select a plan based on the amount of your data requirements and the duration of your usage.
For example, a plan with 50GB of data and a usage period of 30 days will allow you approximately 1.6GB of data per day.
What if I want to use the service in more than one country?
We offer wide range of excursion packages.
Kindly select from the following excursion plans based on the country or region you would like to visit:

Round Trip to Asia & Oceania A
Tour of Asia & Oceania B
Round trip to Europe
Round the World A
Round the World B
