Topping up a prepaid phone with crypto is, mechanically, the closest thing to spending Bitcoin like cash you can do online. There is no shopping account, no card, no shipping address. You enter the recipient's phone number, pick an amount, pay from your wallet, and within ten or so minutes the carrier credits the airtime or data. The whole thing settles in 166 countries on this catalog.
It is also the most operationally fragile thing in the gift-card world. Carriers reject malformed numbers silently. Some operators only deliver during local business hours. A few countries split top-ups by SIM type (regular, IoT, M2M) in ways the dropdown can't fully expose. This guide is what we wish we'd known before shipping the top-up flow.
How mobile top-up differs from a gift card order
A gift card order delivers a code by email. Mobile top-up does not. The carrier pushes the credit directly to the phone number you entered, and the only confirmation you get is a notification on the recipient's phone (and, on most networks, a balance-update SMS). The order page on this site shows the same status — pending, paid, fulfilled — but "fulfilled" means "the carrier accepted the top-up and queued it", not "the user saw the SMS." Carrier-side delays can stretch fulfilment by anywhere from a few seconds to (rarely, in MENA / sub-Saharan Africa) a few hours.
Floors and ceilings differ too. Gift cards on this catalog have a $50 USD-equivalent minimum. Mobile top-up has a $5 minimum (top-ups are smaller, more frequent) and a $1,000 ceiling (most carriers reject single top-ups above ~$200, but some Brazilian and Indian operators support up to $500 and we leave the ceiling generous).
The five-step flow
- Pick the country. The dropdown is grouped by region (Americas, Europe, MENA, Africa, Asia, Oceania). Search by country name, dial code or ISO-2. The country sets the dial-code prefix, the local currency and the operator list.
- Enter the phone number. No leading zeroes, no spaces, no dashes — just the digits after the country code. The flow normalizes to E.164 (the international format) before sending it to the carrier. We strip
+,00, and the country dial code if you accidentally include them. If the number is shorter than the country's minimum or longer than its maximum, the form blocks submit before payment. - Pick the carrier. Some countries auto-detect the carrier from the prefix (the first 3–4 digits after the dial code identify Vodafone vs MTN vs Orange in most markets). Others require you to pick. The carrier list is fetched live and only shows operators that are currently online — if Vodacom Mozambique is in maintenance, it won't appear.
- Pick the amount. Operators usually expose fixed denominations ($5, $10, $20, $50, $100 equivalent in local currency) and sometimes a custom-amount range. The form converts to your preferred display currency in real time.
- Pick a coin and pay. Same 13-coin set as gift cards: BTC, XMR, ETH, USDT-{TRC,ERC,SOL}, LTC, BCH, SOL, DOGE, DASH, TRX, BNB. The pay page shows a QR + address + locked rate; the chain polls every 12 seconds.
Countries where the flow is reliable
From operational data, the most-reliable mobile top-up corridors are: India (all operators, sub-30-second delivery), Brazil (TIM, Vivo, Claro, Oi — 1-2 minute delivery), Mexico (Telcel especially), Philippines (Globe, Smart), Nigeria (MTN, Airtel, Glo), Egypt (Vodafone, Orange, Etisalat), the entire EU (especially Vodafone and Orange across markets), and USA (T-Mobile prepaid, Mint, Tello, Cricket).
Countries where it gets weird
- China (China Mobile, China Unicom, China Telecom) — top-ups work but require the SIM to be registered with a Chinese ID, which is the user's problem, not ours. We deliver; the carrier accepts only if the SIM is in good standing.
- Russia — sanctions affect routing. Some operators reject international top-ups for sanctioned customer segments. We list MegaFon, MTS, Beeline, Tele2 and they generally work; corporate SIM numbers may not.
- Iran — not on the list, sanctions.
- North Korea — not on the list.
- Cuba (Cubacel) — works, but delivery can take several hours during peak hours.
- Some sub-Saharan operators reject top-ups above $20 — pick smaller amounts and split into multiple orders if needed.
What you can and can't top up
Prepaid airtime and data: yes, on every supported carrier. Postpaid bills: in some countries (the UK with EE, France with Orange / Bouygues / SFR / Free Mobile, most US carriers) the same flow works for paying a postpaid bill — the carrier treats the credit as a partial bill payment. In countries where postpaid is a separate product (most of MENA), our flow only handles prepaid airtime.
Bundles (24-hour data passes, weekly minute packs) are not exposed through the dropdown — once the airtime credit hits the SIM, the user activates the bundle on the carrier app or by USSD code (e.g. *123# in Egypt). We can't pre-buy a specific bundle for you.
Privacy considerations
Mobile top-up is the closest thing to anonymous mobile spending available, but it is not actually anonymous on the carrier side. The carrier sees the phone number it credited and the local-currency amount. They don't see your wallet, your IP or your email. If the SIM is registered to a real identity in the destination country (which it almost always is), the credit is linked to that identity at the carrier. If you're topping up your own SIM with crypto for privacy reasons, what you've actually achieved is "the carrier doesn't know I paid with Bitcoin" — useful, but not the same as "untraceable."
Bottom line
