Sim carrier

What l have to do i get a iphone from my family they live in japan and now i put my dna sim card and it say that sim card not valid in our carrier location contact your service to open its i can use  Wi-Fi but SIM card service not working.


  • The service should work as soon as you put the DNA SIM card in a phone.

    Please see my answers here regarding using a Japanese phone in Finland:

    If the same issue doesn't occur with the same SIM card in a European phone, this might be the issue.
