A friendly reminder: It is recommended to insert and activate the SIM card upon arrival at the destination to avoid premature timing; whether hotspot/network sharing is supported depends on the plan.
(Android phones need to manually enter the APN as shown below to use this feature)
Japanese telecommunications operator IIJ recently discovered that, except for iPhones which do not require configuration, almost all other dual-SIM Android phones require manual APN addition. Please refer to the information below for configuration:
After you have finished entering the information, please remember to click "Save" and select the APN you set.
If you still cannot connect to the internet after setting the APN correctly, please restart your device. If you still cannot connect, try inserting the chip into your iPhone or Samsung phone to enable the chip and establish a connection, then switch back to your original phone.
※ Notes:
The first day begins the moment the physical card is inserted (regardless of when it is inserted, Taiwan time applies), and ends at midnight on the same day.
Daily traffic updates are made after midnight (calendar day, not 24-hour).
