How to top up Claro and WOM Colombia with crypto
Claro and WOM are two of Colombia's main prepaid mobile carriers. Both can be topped up on Cryptorefills using USDT, USDC, SOL, BTC on Lightning, or any of the other supported coins. Enter the Colombian number in international format (+57 followed by the ten-digit subscriber number), select the carrier and denomination, pay with crypto, and the credit is applied to the number within minutes.
How to enter a Colombian mobile number correctly
Colombian mobile numbers are ten digits long and begin with 3. In international format, the country code +57 is added before the ten-digit number, with no leading zero to remove. A number written locally as 300 XXX XXXX becomes +57 300 XXX XXXX in international format, or +573XXXXXXXXX without spaces.
Enter the number without spaces or hyphens in the Cryptorefills checkout field. Colombian number portability means the prefix does not reliably indicate the current carrier. Confirm the carrier with the recipient if you are unsure whether the number is on Claro or WOM before selecting.
Claro or WOM, how they differ
Claro is a major carrier in Colombia and operates the broadest network, with coverage reaching smaller cities and rural areas where other carriers are less present. It is the default choice for most prepaid users in Colombia, particularly outside Bogotá and Medellín. WOM entered the Colombian market more recently with aggressive data pricing and has grown its base quickly among urban users who prioritise data over coverage breadth. For recipients in major cities, either carrier works well. For recipients outside urban centres, Claro's coverage advantage is more relevant.
Which crypto to use for Colombian top-ups
USDT on Tron is the most cost-effective option for small top-ups. Transaction fees on Tron are consistently below $0.01, which matters when the top-up itself is $5 or $10. BTC on Lightning is equally low-cost and settles in seconds. USDC on Solana is a practical alternative for Solana holders. For larger amounts, the fee difference between networks narrows and the choice of coin matters less than availability in your wallet.
Step-by-step: top up Claro or WOM Colombia with crypto
Step 1. Go to the Colombia mobile top-up page on Cryptorefills and select Claro or WOM from the carrier list.
Step 2. Enter the recipient's number in international format: +57 followed by the ten-digit Colombian mobile number, starting with 3.
Step 3. Select the denomination.
Step 4. Choose your coin and network. Copy the exact amount shown at the payment screen, do not round the figure. A payment that falls short by any amount will leave the order pending until the window expires.
Step 5. Send the payment. The top-up is applied to the number within minutes of on-chain confirmation. An email confirmation is sent to the address you provided.
What to do if the top-up does not arrive
If the credit has not appeared within 30 minutes of payment confirmation, contact Cryptorefills support with the transaction hash and order number. For guidance on number format and how to avoid the most common top-up errors across LATAM carriers, the mobile top-up number guide covers the region in full.
Frequently asked questions
Can I top up a Colombian Claro or WOM number from outside Colombia?
Yes. Cryptorefills processes international top-ups. You can be located anywhere and top up a Colombian number as long as you enter it in international format (+57 followed by the ten-digit subscriber number) and select the correct carrier.
How do I know if a Colombian number is on Claro or WOM?
Number portability in Colombia means the prefix is not always a reliable indicator of the current carrier. Confirm the carrier with the recipient before selecting it at checkout. Sending a Claro top-up to a WOM number, or vice versa, will credit the wrong carrier account.
What is the cheapest way to pay for a small Colombian top-up?
USDT on Tron and BTC on Lightning both carry fees below $0.01. For a $5 or $10 top-up, either of these is the most cost-effective choice. USDC on Solana is also low-fee. Ethereum mainnet gas fees are disproportionate for small top-up amounts.
How long does it take for the credit to arrive?
Most top-ups are applied within minutes of on-chain confirmation. Tron and Solana confirm in under a minute; BTC on Lightning settles near-instantly. If the credit has not arrived within 30 minutes, contact Cryptorefills support with the transaction hash and order number.
Do I need a Cryptorefills account to top up Claro or WOM Colombia?
A delivery email is the only requirement. No account registration or identity verification is needed for standard mobile top-ups. The credit is applied directly to the number entered at checkout.
