Grammarly Pro unlocks advanced writing suggestions, tone and clarity rewrites, and generative AI features for people who write a lot online. If you want to pay for it with a Coinepay virtual card, this guide walks you through what you need, how to create your card, and how to complete checkout on Grammarly's website. It also covers the most common reasons a card is declined and how to work through them.
Coinepay issues virtual cards with an instant card number, expiry date and CVV, all managed from a 24/7 self-service dashboard and the mobile app. You can use these cards to pay for AI subscriptions, software, advertising and online shopping. Grammarly Pro is a recurring subscription, so the key is to have a card ready with enough balance and billing details that match your Coinepay profile.
What you need before you start
- A verified Coinepay account. If you have not signed up yet, register here and complete identity verification (KYC) first, since card services require it.
- A Coinepay virtual card created in the app or dashboard, with its card number, expiry date and CVV visible.
- Enough balance on the card to cover the Grammarly Pro plan you choose, plus any applicable currency conversion. Keep a small buffer so the charge is not rejected for being short.
- Your correct billing details as held by Coinepay — the name, address and postal code associated with your card. Use your real information.
- A Grammarly account (you can create one during sign-up) and access to the email or app you use for verification codes.
Grammarly's plan names, prices and available billing cycles vary by region and change over time. Always confirm the current price on Grammarly's official pricing page before you subscribe.
Step 1: Create or top up your Coinepay virtual card
Open the Coinepay app (iOS or Google Play) or the web dashboard and sign in. If you do not already have a card, create a new virtual card and note its number, expiry and CVV. Add enough funds to cover at least the first billing cycle. Because Grammarly Pro renews automatically, keeping a balance on the card helps avoid a failed renewal later.
While you are in the app, check the billing address on file for your card. You will enter the same address at Grammarly checkout, and a mismatch is one of the most common causes of a decline.
Step 2: Choose your Grammarly Pro plan
Go to Grammarly's official website and sign in, or create an account with your email. Open the upgrade or pricing section and select Grammarly Pro. Pick the billing cycle you want — typically a monthly or annual option, with annual usually priced lower per month. Review exactly what is included and the total shown before continuing, since the annual option charges the full term up front.
Individual vs team plans
Grammarly offers plans for individuals as well as business or team subscriptions that are billed per member. Make sure you are on the individual Pro plan if you only need it for yourself, so you are not charged for additional seats. If you are buying for a business, confirm the seat count before paying.
Step 3: Enter your Coinepay card at checkout
- On the Grammarly payment page, choose to pay by card.
- Enter your Coinepay virtual card number, expiry date and CVV exactly as shown in the app.
- Type the cardholder name as it appears on your Coinepay profile.
- Enter the billing address and postal code that match your Coinepay account.
- Double-check the total, currency and billing cycle, then confirm the purchase.
If Grammarly or your card provider triggers a 3-D Secure (3DS) verification step, you may receive a prompt, a one-time code, or an in-app approval request through Coinepay. Approve it promptly to finish the payment. Once the charge succeeds, your account should switch to Pro and you can start using the advanced features right away.
Step 4: Confirm the subscription and manage renewals
After payment, check your Grammarly account settings for the subscription status and next renewal date, and look for a confirmation email. In Coinepay, you can review the transaction in your card history. Since Grammarly Pro renews automatically, set a reminder before each renewal to make sure your card still has enough balance. If you decide to stop, cancel from Grammarly's account or subscription settings before the next renewal date — cancelling in Grammarly is what stops future charges.
Troubleshooting: why a card gets declined
Most failed payments come down to a handful of causes. Work through these in order.
| Symptom | Likely cause | What to do |
|---|---|---|
| "Card declined" or "payment failed" | Insufficient balance | Top up your Coinepay card so it covers the full plan plus any conversion, then retry. |
| "Billing address does not match" | Address or postal code mismatch | Re-enter the exact billing address and postal code held by Coinepay for that card. |
| Payment page reloads or times out | 3-D Secure not completed | Complete the verification prompt or in-app approval, and make sure notifications are enabled. |
| Declined before 3DS even appears | Card details entered incorrectly | Check the number, expiry and CVV character by character and that the card is active. |
| Repeated declines on an otherwise funded card | Merchant region or card-type checks | See the note below and contact Coinepay support to confirm your card meets the requirement. |
Insufficient balance
An annual Grammarly Pro plan charges the whole term at once, which is larger than a single month. If you planned around a monthly amount, the annual charge can exceed your balance. Confirm the total shown at checkout and fund the card accordingly.
Billing address mismatch
Grammarly's payment processor compares the billing address you type against the one on record for the card. Use the exact details from your Coinepay profile — including abbreviations and postal code format — rather than a different address.
3-D Secure authentication
If a verification step appears and you dismiss it or it expires, the charge is cancelled. Retry and keep the Coinepay app open so you can approve the request or enter the one-time code quickly.
Merchant region and card-type checks
Some online services apply checks based on the region of the card or restrict certain card types. Grammarly may decline a payment if its processor's checks are not satisfied. If your card is funded and all details are correct but the payment still fails, contact Coinepay support to confirm your card meets the merchant's requirement before you try again. Do not use a false address or any method to disguise your location — use your real identity and billing details.
When to contact support
If you have checked your balance, details, address and 3DS and the payment still will not go through, reach out through the Coinepay support channel or our Telegram. For issues on Grammarly's side — such as the plan not activating after a successful charge — contact Grammarly's own support. You can also learn more about Coinepay cards and remittance on our home page.
Note that some Coinepay services are not available in every jurisdiction, and virtual-asset-related services are not offered to residents of mainland China. Card issuance and fund services are provided by licensed partner financial institutions.
