Top Up Zadarma with Crypto

Zadarma does not bill most services through a separate storefront checkout. Its help center sends users to Billing -> Make a Payment, where account funds can be added by card, PayPal, Apple Pay, Google Pay, or bank transfer. SolCard works with that balance-first flow.

Zadarma combines prepaid balance spending with 30-day PBX price plans. Virtual numbers and call costs draw from the account balance, while Standard, Office, and Corporation packages run on plan periods and can also be prepaid annually for different economics.

Zadarma says numbers are extended automatically if enough funds are available. If the balance is too low, the number is blocked, and if payment still does not arrive within 7 days the number is no longer assigned to the account. Fast crypto-funded top-ups matter here.

Some Zadarma numbers connect without documents, but others require a passport or ID card, company registration, proof of address, a utility bill, or even a photo with the passport. Numbers with SMS reception also require verification and three months of prepayment.

Zadarma's eSIM is for mobile internet, not a phone number. No documents are required, but refunds are not possible after activation and the eSIM can only be installed once, so SolCard is useful when you are ready to fund a data plan after checking device compatibility.

If you port an existing number to Zadarma, the company says porting is free with a 12-month prepayment or an Office or Corporation plan. If you keep a third-party number as an external line, channel upgrades are billed at $6 per month for 3 incoming and 3 outgoing lines or $16 for 10 and 10.
