SIM Contracts for Foreign Residents in Japan: Required Documents and Points by Visa Status

For foreign residents starting life in Japan, a smartphone is an essential item. However, many may have questions or concerns such as, “How do I get a SIM contract?”, “I don’t know what documents I need,” or “Does my visa type make a difference?”

This article will clearly explain the “required documents” and “points by visa status” that foreign residents in Japan should know when signing a SIM contract.

Basic SIM Contract Requirements: Documents All Foreign Residents Should Prepare

First, regardless of which mobile carrier you contract with, there are basic documents commonly required. These are necessary for identity verification and confirmation of payment capability.

1. Residence Card (or Special Permanent Resident Certificate)
   • Most Important: This is the sole official identification document proving your legal stay in Japan. Please ensure it is valid and not expired.
   • Note: Check if your address is up-to-date. If you’ve moved, you must complete the address change procedure at your municipal office.
2. Supplementary Identification Documents (if necessary)
   In addition to your Residence Card, you may be asked for additional documents:
   • Passport: May be requested as a supplement to your Residence Card.
   • Driver’s License: If you have a Japanese driver’s license.
   • My Number Card: If you possess one.
3. Bank Account Information (or Credit Card)
   • For Monthly Payments: You can choose between bank transfer or credit card payment.
   • Bank Account: A passbook or cash card for an account opened at a Japanese bank. The account holder’s name must match the contractor’s name.
   • Credit Card: A credit card in the contractor’s name. Overseas-issued cards may sometimes be accepted, but Japanese-issued cards are usually smoother.
4. Certificate of Employment, Student ID, Health Insurance Card, etc. (if necessary)
   • Depending on the carrier and contract details, additional documents such as proof of income or employment, or a student ID may be required. This is especially common when purchasing devices on installment plans or if your period of stay is short.

SIM Contract Points by Visa Status

The ease of signing a SIM contract and the available plans may vary depending on your visa type and the remaining period of stay.

1. Mid- to Long-Term Stay Visas (e.g., Work Visa, Student Visa, Dependent Visa)

• Length of Stay is Key:
  • 1 year or more: You can generally contract with most carriers without issues. Device installment plans are also relatively easy to use.
  • Less than 1 year (3 months to less than 1 year): Contracts are possible, but device installment payments might be difficult. You may need to purchase the device outright, or be advised to opt for short-term contracts (e.g., prepaid SIMs).
  • Short remaining period of stay: Contracting itself may be difficult, or prepaid SIMs and short-term rentals may be recommended. If your remaining period of stay is less than 3 months, it becomes more common for contracts to be declined.
• Note: If your plan has a fixed contract period that exceeds your remaining period of stay, a cancellation fee may be incurred if you terminate the contract midway. Be careful.

2. Short-Term Stay Visas (e.g., Tourist Visa)

• Generally, regular SIM contracts are not possible: Due to difficulties in identity verification, most carriers do not allow contracts for regular voice call SIMs or data-only SIMs for short-term stay visa holders.
• Available Options:
  • Prepaid SIM: Generally for data communication only, with a set validity period. Can be purchased at airports or electronics stores.
  • Wi-Fi Router Rental: Available for rent from a few days to several months.
  • Overseas Roaming: Using your home country’s SIM card in Japan, but this often incurs high charges.

3. Special Permanent Resident / Permanent Resident Visas

• Treated the same as Japanese nationals: You can contract for a SIM with most carriers, just like Japanese nationals. Device installment plans and other services are also available without issues.
• Required Documents: Your Residence Card (or Special Permanent Resident Certificate) will be the primary identification document.

Important Notes and Tips for a Smooth SIM Contract Process

• Always prepare a valid Residence Card: This is the most crucial document. If you are in the process of renewing, inform the carrier and discuss possible arrangements.
• Complete address changes in advance: If the address on your Residence Card differs from your current address, you may not be able to sign a contract.
• All names must match: The name on your bank account, credit card, and contract must all be the same as yours.
• Japanese communication: Contract procedures are mostly conducted in Japanese. If you are not confident in your Japanese, it’s reassuring to have a Japanese-speaking friend or family member accompany you, or choose a store or carrier that offers multilingual support.
• Consider online contracts: Some carriers offer online contracting. While this saves a trip to the store, incomplete documents can delay the process.
• Prepaid SIMs and rental Wi-Fi are also options: These are good choices for short-term visitors or those who want to try out services casually.

Summary

When foreign residents in Japan sign a SIM contract, a valid “Residence Card” and “bank account information (or credit card)” are essential. The ease of contracting varies depending on your visa status and remaining period of stay, so carefully check your situation and choose the appropriate carrier and plan.

If you have any concerns, choosing a mobile carrier with multilingual support will allow you to proceed with the procedures more securely. We hope this article helps you enjoy a comfortable smartphone life in Japan.
