Send mobile credit to Kenya with crypto

Kenya is one of the world's most important crypto-and-mobile corridors — Safaricom's M-Pesa is the dominant financial system in East Africa, and the Kenyan diaspora is one of the fastest-growing in the US, UK and Gulf. FillUpCoin lets you top up a Safaricom or Airtel Kenya number from anywhere, in Bitcoin or USDT, with the KSh balance credited to the recipient's phone and immediately spendable through M-Pesa.

The cost comparison nobody talks about

Figures are typical. Western Union and Remitly fees vary by corridor, payment method, and promotional pricing. FillUpCoin only charges the crypto network fee — $0.50 on USDT TRC-20, pennies on Solana, $1-5 on Bitcoin depending on mempool.

Why send airtime instead of cash to Kenya

• Safaricom airtime can be converted directly to M-Pesa balance via *126#. That means a Safaricom top-up effectively becomes real digital money the subscriber can send to anyone, pay a shop, or use for school fees.
• The Kenyan diaspora remittance corridor from the US and UK is highly digital — most senders are tech-literate professionals who want faster than Western Union.
• Kenya's Central Bank allows M-Pesa transactions to flow internationally through WorldRemit and similar — but with 3-5% fees baked in. Crypto skips those entirely.
• Airtel Kenya is a strong alternative in some regions (Kisumu, parts of the Rift Valley) where Safaricom coverage is thinner.
• The Kenyan Shilling is relatively stable, so a USDT-denominated top-up has very predictable KSh value.

The best crypto for Kenya top-ups

USDT TRC-20 — pairs well with Safaricom's digital-first culture and the Kenyan expectation of near-instant M-Pesa settlement.

You can also pay in Bitcoin (BTC on-chain), Ethereum (ETH), or Solana (SOL). The invoice is denominated in euros, so the sender sees the exact amount in crypto before confirming — no surprise exchange-rate movements.

How it looks from the sender's side

A Kenyan nurse in Birmingham, UK sends KSh 5,000 of Safaricom airtime to her parents in Nakuru every month. Her father converts it to M-Pesa and uses it to pay for farm feed. The transaction time is 90 seconds from her sending USDT to the M-Pesa balance ping arriving on her father's Vivo phone — faster than it would take her to pour tea.

Common senders include United States, United Kingdom, United Arab Emirates, South Africa and Canada — anywhere there's a Kenya diaspora with internet access, our service works. The only requirement on the sender side is a crypto wallet with a positive balance.

Step by step: send credit to Kenya with crypto

1. Open the Kenya refill page and pick the carrier your family uses — Safaricom, Airtel Kenya.
2. Enter the full Kenya mobile number including the country dial code. The site auto-formats it as you type.
3. Pick an amount from €15 to €200. The equivalent in local currency is shown live so you know exactly what the recipient will see.
4. Add an email — this is where the receipt and (if applicable) the voucher PIN land.
5. Pay the crypto invoice. We quote and lock the amount for 20 minutes. BTC, USDT (TRC-20 or ERC-20), ETH, or SOL — pick whichever has the lowest network fee at that moment.
6. The carrier processes the top-up as soon as the payment confirms on-chain. Your family in Kenya sees the balance credit by SMS from the carrier within a minute of confirmation.
