You can easily set it up with just these two.

• ・Insert the SIM card.

Inserting a SIM card with the power on may cause problems, so be sure to turn off the power before inserting the card.


※You can check in advance at each carrier's shop or retailer whether the SIM card is compatible with this model.



• ・Perform initial settings

After inserting the SIM card, turn on the power and setup the initial settings.
There are three important items in the initial setup: "WiFi settings", "Google account settings", and "security settings".
By configuring your Google account settings and security settings, you can use your device with confidence in the future.



• ・Configure APN settings

Once the initial settings are complete, configure the APN settings.
APN is an abbreviation for Access Point Name.
Please check the APN settings on your carrier's website, as they can vary depending on the carrier.


Once the APN settings are complete, you can connect to the Internet using mobile data communication even without WiFi.
