"Can povo really let me keep my Japanese phone number with no monthly base fee?"—for anyone heading abroad for work, study, or a long stay, povo often comes up as a way to hold on to a Japanese number. The short answer: povo2.0 can be a candidate for keeping a Japanese number at no base fee, but you can't simply leave it untouched at zero cost—it requires periodic renewal. On top of that, receiving SMS while overseas isn't guaranteed and depends on several conditions. This article walks through what to verify before you rely on povo2.0 to maintain a Japanese number from abroad, and why it helps to handle your data connectivity separately.
- povo2.0 is one option for keeping a Japanese number with no base fee
- You can't leave it at zero cost forever—renewal is needed roughly every 180 days
- Miss a renewal and you risk suspension, then cancellation—losing the number
- Receiving SMS overseas depends on conditions and isn't guaranteed
- Keep data separate and top up with a data-only eSIM to keep costs down
- povo2.0 has no monthly base fee—you buy "toppings" only when you need them. That makes it a candidate for holding a Japanese number.
- However, you can't maintain it at zero cost indefinitely. If no paid topping (or similar activity) occurs over a set period (officially cited as roughly 180 days), the line is progressively suspended, and continued inactivity after that can lead to contract cancellation. Once a number is lost, recovering it can be difficult.
- Whether SMS arrives overseas depends on conditions—check the official guidance. Keep your everyday data separate from number retention and top up only what you need with a data-only eSIM to keep fixed costs manageable.

What is a "number-retention plan" anyway?
A number-retention plan refers to a low-cost mobile plan used mainly to keep a phone number alive—typically for SMS verification or to preserve a calling number. When you live abroad for an extended period, you'll run into situations where banking, brokerage, government services, and various app logins ask for identity verification tied to a Japanese number. Without that number, some processes simply can't move forward, so for people living overseas, "how to keep a Japanese number" often matters more than the mobile plan itself. With number retention, the goal isn't heavy monthly usage—it's keeping the line from lapsing at the lowest possible cost.
How povo2.0 works at a glance
povo2.0 is one option for number retention, with no monthly base fee. Data, unlimited-calling, and other features are bought as "toppings" only when you need them, so in months you don't use it, there's no base charge. That makes it well suited to anyone who wants to keep their minimum retention cost low. It also supports eSIM, so on a dual-SIM-capable device you may be able to run it without swapping a physical SIM. The "pay only for what you use, only when you need it" approach pairs naturally with number retention, where you typically use little data day to day.
Important: you can't keep it alive at truly zero cost (the 180-day rule)
povo has "no base fee," but you can't leave it untouched with no purchases. According to official guidance, if no paid topping (or similar activity) occurs for roughly 180 days from the day after your last paid topping expires, the line is progressively suspended, and continued inactivity for a further period (officially cited as roughly 30 days) can lead to contract cancellation. In other words, maintaining the number depends on periodic minimum toppings. On a long stay abroad, it's easy to forget this renewal and lose the number. Adding the deadline to your calendar or reminders is a good safeguard. Periods and conditions may change, so confirm the latest details on povo's official site.
| Item to check | Key point (as of June 2026 — verify officially) |
|---|---|
| Base fee | None (toppings are separate) |
| Number-retention condition | A paid topping (or similar) is said to be needed roughly every 180 days |
| Suspension → cancellation | Cancellation may follow if there's no activity for roughly 30 days after suspension |
| SMS | Confirm whether reception works and how it's handled overseas |
| Overseas use | Topping-based; not suited to long-term data |
| eSIM | Supported |
povo's "zero fee" is appealing, but the real pitfall for people living abroad is a missed renewal. Forget the twice-a-year minimum topping and you can move from suspension to cancellation—and lose the number. If your goal is simply to stay able to receive SMS verification, think beyond price alone and treat renewal management as part of the plan. That way you're far less likely to be caught out when it matters.
What happens with SMS reception and data overseas?
The biggest concern for people living abroad is "will SMS verification reach my povo number while I'm overseas?" This depends on multiple factors—the carrier, the plan, your device settings, the country you're in, and the sender's setup—so reception isn't guaranteed. Especially for things like banking, government, or official registrations where reliable identity verification is essential, it's important not to travel without confirming this first. We recommend the following preparations:
- Before you leave, test SMS reception on the actual device (try sending yourself a verification code once).
- Don't rely on SMS alone—set up authenticator apps, email verification, and backup codes as alternatives.
- Check each service's official guidance in advance to confirm whether important procedures will work.
Also, because povo's overseas data is topping-based, it isn't suited to long-term data use. It's easier to stay organized if you separate the role of your retention number from the role of your everyday internet data.
A different angle: treat number retention and data as a "division of labor"
A common stumbling block when setting up your phone for life abroad is trying to cover everything with a single contract. Forcing number retention, calling, and data into one line tends to strain somewhere—ending up overpriced or making renewal harder to track. That's why a division-of-labor approach works well. Let a number-retention plan like povo handle keeping your Japanese number and SMS verification, and top up your day-to-day internet on location with a data-only eSIM, only as much as you need. This keeps fixed costs down to the minimum for number retention, while letting you choose data to match your length of stay and usage. On a dual-SIM-capable device, you may be able to run povo for retention and an eSIM for data on the same phone (check device compatibility in advance).
| Role | Handled by |
|---|---|
| Keeping the phone number / SMS verification | povo (number retention) |
| Calls | povo (add an unlimited-calling topping if needed) |
| Everyday data | A data-only eSIM, only as much as you need |
| Internet while traveling or on a long stay | A data-only eSIM for just the period you need |
If you just want to add data as needed, a data-only eSIM is one option. Bloomy's data plans are organized by capacity, so you can choose based on how many days you'll stay and how you use data (capacity, coverage, and terms can change, so check the comparison page for the latest). Note that Bloomy is a data-only eSIM—it does not provide a phone number or SMS. Handle number retention and SMS verification on the povo side. App-based calls such as WhatsApp may work wherever you have a working data connection.
Who povo suits—and who it doesn't
A good fit if you…
- Want to keep just a Japanese number at minimal maintenance cost
- Use little data normally and prefer to buy it only when needed
- Can manage the renewal (minimum topping) every six months
- Want a simple eSIM-based setup
Probably not for you if you…
- Find renewal management a burden and want a plan that won't lapse if left alone
- Want to use a steady amount of data every month
- Need reliable SMS reception overseas (reception is not guaranteed)
There's no single right answer—the practical choice depends on how you use your phone and whether you can manage the renewals. Deciding your goal for number retention first (SMS verification only, or calls too) makes it easier to judge whether you need toppings.
Common mistakes (avoidable with a little checking)
- Going too long without a topping and missing the suspension conditions: add the six-monthly minimum topping to your calendar.
- Not checking the conditions for overseas SMS reception: test on the actual device before leaving and set up alternative verification.
- Trying to cover overseas data with toppings alone and overpaying: separating long-term data onto an eSIM keeps things clearer.
- Trying to consolidate everything into one contract and making it hard to manage: splitting retention and data lets you optimize each.
Pre-departure checklist
- Confirm the suspension and cancellation conditions (periods) on povo's official site
- Decide how you'll manage the six-monthly minimum topping (calendar, etc.)
- Test overseas SMS reception on the actual device before you leave
- Set up authenticator apps, email verification, and backup codes
- Plan to top up data with an eSIM as needed, and estimate capacity from your length of stay
- Check whether your device supports eSIM and dual SIM
What Bloomy can do (preparing your data connectivity)
If you want to leave number retention to a plan like povo while lightly preparing your everyday internet on location, a data-only eSIM is one way to do it. Bloomy offers a comparison page that's easy to navigate even for first-timers, letting you search plans by destination, data capacity, and number of days. Start by entering your destination and length of stay to get a sense of the capacity you'll need. With number and SMS on the povo side and data on the eSIM side, this division of labor helps you keep fixed costs down while getting your phone ready for life abroad.
