■ Can you use my phone number for calls and SMS?

<Outgoing and incoming calls from a local phone number >

Currently, Trifa does not offer plans with phone numbers. 

Please use the call function of LINE, Instagram, 050 plus, etc., which are using data communication (internet connection). 

<Outgoing and incoming calls from Japanese phone numbers> 

If you need to call or use SMS, you cannot use the trifa's eSIM. 

You can do so by turning on the SIM you used in Japan.  

Please note that you are responsible for your own calling charges. 

If you do not use calls or SMS, please switch to Triffa's eSIM for data communication. 

(Please note that using a SIM used in Japan for data communication may lead to high charges.) 

For details, please refer to the Terms of Use.
