SIM with a Japanese phone number for foreigners
A real Japanese mobile number you can call and be called on, plus enough data for daily use. This is the plan that unlocks what a data-only SIM cannot.
- Japanese mobile number that makes and receives calls
- Needed for bank accounts, job applications and rental contracts
- Data at a daily commuter level
Things you cannot do without a Japanese phone number
Open a Japanese bank account: most banks require a Japanese mobile number that can receive calls and do not accept data-only numbers.
Apply for part-time or full-time jobs: employers call rather than text. No number often means a missed opportunity without ever knowing why.
Sign a rental contract and complete procedures at your city office: both have a required phone number field.
Receive deliveries: couriers call to arrange redelivery when you are not home.
Moving your number from another carrier
If you already have a Japanese number with another carrier, you can usually keep it when you switch. You need a number transfer code (MNP) from your current carrier before you start.
Do not cancel your old contract before you get the code: cancelling first means losing the number for good. Message us before you do anything if you are not sure.
Frequently asked questions
Is it a real 090/080/070 number?
Yes. This is a real Japanese mobile number, not an app-based number. Details are confirmed before you sign up.
Is signing up for a voice plan harder?
Identity verification is stricter than for data-only plans. In exchange we guide you step by step, and that guidance is exactly what you pay shibaSIM for.
