If your eSIM provider goes out of business, any prepaid credit or "lifetime" balance is typically lost, since there's no one left to honor it or issue a refund. An already-installed, connected eSIM may keep working for a while, since it runs on the underlying mobile network, not the provider's servers — but topping up, managing, or getting support for that plan generally stops the moment the company disappears.
Most eSIM resellers are not the mobile network itself — they're a layer of software and a wholesale agreement sitting on top of one. Surfroam puts the core risk plainly: "the eSIM market is young and competitive. Startups come and go. A company that exists today might shut down in six months — and your 'lifetime' balance vanishes with it." When that company stops operating, its billing system, its support inbox, and its own account infrastructure go with it, even if the mobile network underneath was never technically at fault.

Not necessarily, and a real documented case shows why. When the reseller 5ber quietly collapsed in 2024–2025, customers with profiles already installed kept connecting normally, because the actual mobile connection ran through the underlying carriers' own servers — "5ber never operated them." What broke was 5ber's own "entitlement server," the layer that verified a purchase before letting a customer install a new profile or download license. Existing, already-installed profiles worked; buying anything new, topping up, or reaching support did not.
This is where the exposure concentrates. A "lifetime" or no-expiry balance is, by design, credit you've prepaid that's meant to sit with the provider and be drawn down slowly, potentially over months or years — which is also how long that unused credit sits exposed to the provider's own survival. Surfroam's advice is to research "how long they've been operating," whether they have "real telecom infrastructure," and whether they're "a registered business entity" before loading up a large balance, since "a provider with years of history is safer than a flashy newcomer with suspiciously low rates."
It narrows the exposure — it doesn't remove it. A co:sim plan — the Japan eSIM, for example — is a single purchase with its own fixed data amount and validity window; there's no ongoing stored "wallet" balance accumulating with the company over months or years, so there's no large pile of prepaid, unused credit sitting exposed to co:sim's own future the way a no-expiry balance would be. Your financial exposure on any one order is capped at what that order cost, for that order's own validity period, not an amount you loaded up in advance for later trips. That's a real, checkable difference from the no-expiry model above, and it's honest to say so.
It does not mean the risk disappears entirely: an already-installed, already-connected eSIM would be expected to behave like the 5ber case, continuing to work through the underlying network for as long as that network relationship holds, but a very recent purchase not yet installed, or a self-service refund request submitted right as a company stopped operating, would have no one left to process it — self-service refunds are a live process co:sim's support and payment systems carry out, not something that executes itself with no company behind it.
Not necessarily, based on how similar shutdowns have actually played out. An eSIM profile that's already installed and connected typically keeps working for as long as the underlying mobile network keeps honoring the roaming or wholesale agreement behind it, because the data connection itself runs through that network's own infrastructure, not through the provider's website or app. What stops working immediately is everything that depends on the provider's own systems: buying a new eSIM, topping up an existing one, changing account details, or reaching customer support. In the documented 5ber shutdown, customers with eSIMs already installed kept connecting normally for a long stretch after the company itself had effectively stopped functioning, because the mobile network side was never actually run by 5ber in the first place.
The risk is concentrated in exactly the amount of unused credit you're holding with that company at any given time. A "lifetime" balance is designed to be loaded once and drawn down gradually, which by nature means a meaningful sum can sit unused with the provider for months or years, fully exposed to whether that company is still solvent and operating whenever you finally go to use it. Surfroam's blunt framing of this is that a company "that exists today might shut down in six months — and your 'lifetime' balance vanishes with it." The practical mitigation experts suggest is to only load what you'll realistically use in the near term, and to check a provider's operating history and whether it's a registered business before committing a larger balance, rather than treating "lifetime" as a promise the industry can actually back.
No, and it would be dishonest to claim that. It narrows the exposure in a real, checkable way: each co:sim plan is bought once with its own defined data amount and validity window, so there's no accumulating "lifetime" balance sitting with the company for months or years the way a no-expiry wallet would be — your exposure on any one purchase is bounded to that single order. But narrowing isn't eliminating. If co:sim, or any provider, stopped operating entirely, a very recent purchase that hadn't been installed yet, or a refund request filed right at that moment, would have no company left behind it to process — the self-service refund window described on co:sim's own policy pages assumes an operating company processing requests, which is exactly the scenario this article is about not being available.
Check the same things industry guides recommend for any prepaid service: how long the company has actually been operating, whether it appears to run on real wholesale network agreements rather than reselling someone else's reseller access, and whether it's a properly registered business rather than an anonymous storefront. A provider with several years of an operating track record and transparent, checkable information about its own network partnerships is a materially safer bet than a brand-new site advertising unusually cheap "lifetime" balances with no history behind it. None of this guarantees a company's future, but it's the same due diligence worth doing before prepaying any business a meaningful amount of money in advance. It's also worth noticing how much a provider actually tells you about the plan you're buying — a page that names the underlying network, the exact data amount, and the validity window is easier to verify against reality than one that only advertises a price.
Yes. Regulatory action against a provider is a separate route to the same practical outcome. In January 2024, India's telecom regulator ordered Airalo and Holafly's apps removed from the Indian app stores over licensing requirements for foreign SIM sales, even though both companies kept operating normally everywhere else in the world. A removal like that doesn't necessarily cut off service already in use abroad, and it's a narrower, single-market event rather than a company-wide failure, but it does illustrate that a provider becoming unreachable to you isn't purely a bankruptcy question — it can also be a licensing or compliance action specific to one market, or a payment processor dropping a provider, or any number of business disruptions short of insolvency. All of them point toward the same practical habit: don't prepay more than you're comfortable being temporarily unable to manage or get support for.
A co:sim plan is a single, fixed-validity purchase rather than a stored balance, which narrows but doesn't erase this risk — buy what you'll use for the trip you're planning.
