How to Pay for Proton Mail, VPN and Unlimited With Crypto (2026)
Proton is one of the few mainstream subscription services that accepts cryptocurrency at all: you can pay for any Proton plan with Bitcoin. So why did more than 900 SolCard holders make about 2,400 Proton purchases by card over the past 12 months, a figure that more than doubled between the first and second half of the period?
Because Bitcoin is the only coin Proton takes, it is not offered at signup, and it does not renew a subscription on its own. If your crypto is USDC on Solana or USDT on Ethereum, the direct option does not help you. A crypto-funded Visa or Mastercard does, and it behaves like any other card on Proton's billing page.
This guide covers what Proton's plans cost in 2026, exactly what Proton accepts, the card route step by step, and an honest comparison of paying with Bitcoin versus a card.
Proton sells individual apps (Mail, VPN, Drive, Pass, Calendar) and bundles. The two plans most people land on are Mail Plus and Proton Unlimited. Prices below are from Proton's pricing page in USD; Proton also bills in EUR and CHF, and in several local currencies when you pay by card.
| Plan | Monthly billing | Annual billing | What you get |
|---|---|---|---|
| Proton Free | $0 | $0 | 1 GB, one address, basic VPN |
| Mail Plus | $4.99/mo | $3.99/mo ($47.88/yr) | 15 GB, 10 addresses, custom domain, unlimited folders and hide-my-email aliases |
| Proton Unlimited | $12.99/mo | $9.99/mo ($119.88/yr) | 500 GB, all Proton apps at their Plus tier: Mail, VPN, Drive, Pass, Calendar |
Proton also offers Duo and Family bundles, standalone VPN Plus, Drive Plus and Pass Plus plans, and business tiers; check the pricing page for current figures, since Proton adjusts them by region and runs promotions through the year.
The average Proton purchase on SolCard over the last year was about $18, which is consistent with most people choosing monthly billing on Unlimited or Mail Plus rather than paying a year up front.
- Cards ("all major credit and debit cards")
- PayPal
- Apple Pay (Safari on macOS, iOS, iPadOS) and Google Pay
- Bitcoin, for any plan, but only after you create a free account and upgrade from account settings; it is not shown at signup
- Cash in USD, EUR or CHF, and bank transfer in the same three currencies
Two things matter here. Bitcoin is the only cryptocurrency on the list; there is no USDC, USDT, SOL or ETH option. And a card is the method that renews a subscription automatically, so it is the one Proton's own docs treat as the default.
Most crypto that gets loaded onto cards is not BTC. Among SolCard deposits, roughly two-thirds arrive on Solana as SOL, USDC or USDT, and most of the rest is USDT or USDC on Ethereum, BSC, Arbitrum or Base. Converting a stablecoin to Bitcoin to pay a $4.99 invoice means an exchange, a spread and a network fee for a tiny purchase. Loading the stablecoin onto a card skips all of that.
A Bitcoin payment to Proton is a one-off. A card on file renews Mail Plus or Unlimited every month or year without you doing anything, which is the whole point of an email account you rely on. If a renewal fails, you get a grace period and warnings, but nobody wants their mailbox on a manual payment schedule.
Proton VPN in particular is often bought inside the iOS or Android app, where the App Store or Google Play handles billing. Those stores take cards, not Bitcoin. The same applies if you upgrade from inside the Proton Mail mobile app.
Some users simply prefer to pay for privacy tools from a balance that is not tied to their everyday bank account. That is a discretion preference, not anonymity: a crypto card is still a regulated payment product issued in your name, and Proton still knows who its customer is. The card just keeps a subscription line off a statement your bank sees.
Sign up for SolCard and issue a virtual Visa or Mastercard. The card is ready in about 30 seconds. The virtual card costs $10 to issue, charges 5% per top-up, needs a minimum $50 top-up, and has a $5,000 monthly load limit. Verified users on the Platinum tier pay 0% on top-ups, which is worth it if the card also carries other subscriptions.
Send USDC, USDT or SOL from any wallet to the deposit address shown in the app. Solana deposits settle in seconds; Ethereum, BSC, Arbitrum, Base and Polygon are also supported. Load at least a couple of months of your plan so renewals do not bounce.
Log in at proton.me, open Settings → Subscription, pick Mail Plus or Unlimited, choose monthly or annual, and select Credit/debit card. Enter the card number, expiry and CVV from the SolCard app. Set the billing currency to USD if you loaded a USD balance, so there is no conversion on Proton's side.
If Proton's bank asks for 3-D Secure, the one-time code is emailed to the address on your SolCard account. Enter it and the payment completes.
Proton charges the card on each renewal date. A monthly Unlimited plan needs about $13 available on that day; annual needs about $120 once a year. Turn on low-balance alerts in the SolCard app so a renewal never fails for lack of funds.
| Route | What you need | Cost on a $12.99/mo Unlimited plan | Renews automatically? |
|---|---|---|---|
| Bitcoin to Proton | BTC in a wallet you control, a free Proton account first | Network fee for the BTC transfer (varies) | No, manual each time |
| SolCard Virtual | USDC, USDT or SOL | $12.99 + 5% top-up = about $13.64 | Yes |
| SolCard Platinum | USDC, USDT or SOL, verified account | $12.99 + 0% top-up = $12.99 | Yes |
| Bank card | A bank that issues one | $12.99 plus any FX fee | Yes |
If you already hold Bitcoin and do not mind paying by hand, Proton's direct option is the cheapest. If you hold stablecoins or SOL, or you want the plan to renew itself, a crypto card costs roughly the same as a bank card and does not require a bank.
Check the balance covers the plan price. Then confirm the billing currency matches the currency on the card; a USD card paying a EUR invoice may be declined by Proton's processor rather than converted. Try the annual plan if a monthly attempt fails twice; some processors treat the first charge from a new card more strictly.
The most common cause is an empty balance on the renewal date. Top up and retry from Settings → Subscription. Proton keeps the account in a grace state for a while before downgrading, so you have time.
That is expected at signup. Create the free account first, then upgrade from Settings → Subscription; Bitcoin appears as a payment method there.
Yes, but only Bitcoin, and only when you upgrade an existing free account from settings. No other cryptocurrency is accepted directly.
Not directly. Load the stablecoin onto a crypto-funded Visa or Mastercard and pay Proton with the card, which Proton accepts like any other card.
Yes. Buy VPN Plus or Proton Unlimited on proton.me with a crypto-funded card, or with Bitcoin from account settings. Purchases made inside the iOS or Android app go through the app store and need a card there.
Proton says it accepts all major credit and debit cards and does not list a prepaid restriction. SolCard holders made around 2,400 Proton purchases in the last 12 months; if a charge is declined, check the balance and billing currency first.
$12.99 per month on monthly billing, or $9.99 per month billed annually ($119.88 a year), in USD at the time of writing. Mail Plus is $4.99 monthly or $3.99 per month annually.
Yes. Proton stores the card and charges it on each renewal date. Keep the balance above the plan price on that day.
