"I can't get a phone contract without a bank account. But I can't open a bank account without a phone number."
This "Chicken and Egg" problem causes headaches for countless foreigners. If you have just arrived in Japan, you are likely hitting this exact same wall.
Let's start with the conclusion: JP Smart SIM is the "Ultimate Startup Tool" to break this infinite loop. No credit card required. You can get a phone number as early as the next day with just your Residence Card.
However, I do not recommend using this SIM "forever." In this article, as someone who has supported many foreigners in setting up their lives in Japan, I will explain why you should use JP Smart SIM "only for the first 3 months (The Bridge Strategy)" and reveal the smart roadmap for switching plans later.
No bank account or credit card needed. Delivered as fast as the next day with just a Residence Card.
JP Smart SIM is a SIM service specialized for foreigners, utilizing the NTT DoCoMo network. The reasons why it is chosen so often are clear.
Japan's major carriers (DoCoMo, au, SoftBank) have strict screening processes, making it almost impossible for foreigners to get a contract immediately after arrival. The biggest feature of JP Smart SIM is that there is 'No Screening'.
Usually, a credit card or a Japanese bank account is mandatory for mobile contracts. However, JP Smart SIM supports a payment method called "Smart Pit." This allows you to pay your monthly fees in cash at convenience stores like Lawson and FamilyMart.
There is no "2-year binding" or high cancellation penalty often found in Japanese mobile contracts. You are free to use it as you please, such as "using it for just one month before returning home" or "switching if you find a cheaper SIM." The fact that the cancellation fee is ¥0 is a huge relief during the unstable period of starting a new life.
Can't read the Japanese contract? Don't understand the staff's explanation? No need to worry. The support team handles inquiries via chat in English, Chinese, and Vietnamese.
First, secure a phone number with this SIM, then complete your address registration at the city hall. This is the first step of your life in Japan.
Application takes only 5 minutes. No difficult Japanese contracts.
"No screening" is attractive, but how much does it actually cost? Let's look at the real numbers.
JP Smart SIM has several plans, but considering cost performance, there is really only one choice.
This plan, offering 20GB for ¥2,178 (approx. $15 USD), offers the best balance. Note that there is an "Unlimited Plan (MAX)," but it has a strict limit of 10GB per 3 days, so avoid using it as a replacement for home internet.
The costs incurred at the time of application are as follows:
Call charges are ¥22/30 seconds. There is no "All-you-can-call" plan, so if you make too many phone calls, your bill will skyrocket. Be sure to use LINE calls or similar apps when talking to friends.
We gathered voices from actual users.
I failed the screening for all other SIMs, but I was able to contract with JP Smart SIM. Since it uses the DoCoMo network, it connects well even in the subway.
We will also honestly share the downsides.
If you want to thoroughly compare speeds and specs with other companies, please refer to the following article. [【2026 Edition】Best SIM Cards for Foreigners: Airalo vs Sakura vs Rakuten vs Mobal](/en/essentials/japan-sim-card-comparison-2026-R)
Answering the question, "So, how does it compare to the others?"
| Feature | JP Smart SIM | Rakuten Mobile | Mobal |
|---|---|---|---|
| Network | DoCoMo (Stable) | Rakuten + au | SoftBank |
| Monthly (20GB) | ¥2,178 | ¥2,178 | High |
| Payment | Conv. Store / Card | Card / Bank Acc | Card / PayPal |
| Screening | None | Strict | None |
| Contract Term | No binding | No binding | No binding |
Rakuten Mobile has the strongest specs with "Unlimited Data" and "Free Calls." However, the screening is very strict. There are many cases where foreigners who have just arrived in Japan and do not have a credit card are rejected.
Strategy: The correct move is to build a credit history with JP Smart SIM first, then switch to Rakuten.
If you are confident about the screening, go here. Unlimited data for ¥3,278/month.
Mobal's strength is that it accepts "PayPal," but the monthly fee tends to be expensive for long-term residents.
Strategy: Choose Mobal for short trips, but JP Smart SIM keeps costs lower for living in Japan.
PayPal accepted. Stable communication on SoftBank network.
This is a unique proposal from this article. Instead of making JP Smart SIM your final goal, here is the smart way to use it as a "Stepping Stone (Bridge)."
By following these steps, you will be completely free from the worry of "not being able to get a mobile contract."

A: JP Smart SIM requires no credit check, accepts convenience store payments, and does not require a Residence Card for signup. It uses a prepaid model with no long-term contract, ideal for foreigners who are uncertain about their stay length.
A: JP Smart SIM's standard data-only plans do not include a voice number. If you need an 080/090 number for bank or PayPay registration, choose their voice plan add-on, or use GTN Mobile or Mobal instead.
A: The Bridge Strategy involves using JP Smart SIM as a cheap interim SIM for 1–3 months while you establish a Japanese bank account and credit card. Once eligible, you switch to Rakuten Mobile for its ¥0/month plan (under 3GB) and long-term savings.
A: JP Smart SIM uses MVNO allocation on major carrier networks. Standard speeds are adequate for streaming and video calls, but like most MVNOs, speeds can slow during peak hours (12–13pm and 6–9pm in urban areas).
A: JP Smart SIM can be recharged at convenience store kiosks (7-Eleven, Lawson, FamilyMart) using cash, or online by credit card. The prepaid balance has a validity period, so top up before it expires.
