Moving to Japan brings an immediate "chicken and egg" problem: you need a phone number to open a bank account, but you usually need a bank account (or a Japanese credit card) to get a phone number.
If you walk into a major Japanese carrier (Docomo, SoftBank, au) without a Japanese credit card or a long-term visa, you will likely be rejected.
In this guide, we compare the top 4 SIM card providers specifically for foreign residents in 2026. We analyzed price, language support, and — most importantly — ease of application.
Top Pick for 2026: GTN Mobile
Get a Japanese phone number in 10 minutes. No credit card required. 13-language support.

Frequently Asked Questions
Q: Can I get a SIM card in Japan without a credit card?
A: Yes. GTN Mobile accepts convenience-store payment with no deposit, so you can sign up with just your Residence Card. Sakura Mobile also accepts cash via Smart Pit, but requires a ¥20,000 deposit.
Q: What do I need to apply for a SIM card as a foreigner?
A: For long-term (voice + number) SIMs, you generally need your Residence Card (Zairyu Card) and a payment method. Some providers also ask for a Japanese address.
Q: Which SIM card has the best English support?
A: Mobal and Sakura Mobile operate natively in English. GTN Mobile supports 13 languages including English, Chinese, Vietnamese, and Nepali. Rakuten Mobile's support is almost entirely in Japanese.
Q: Can I keep my number if I switch providers later?
A: Yes. Japan supports MNP (Mobile Number Portability), so you can move your number — for example from a starter SIM to a cheaper plan once you have a Japanese credit card.
Q: Is a tourist eSIM enough if I'm moving to Japan?
A: No. Data-only tourist eSIMs don't include a Japanese phone number, which you need for a bank account, apartment contracts, and many apps. Residents should get a voice SIM.
