How to Top Up a Prepaid Phone in Argentina (2026)
TL;DR
You can top up an Argentine prepaid line at a kiosk with cash pesos, in the carrier app (Mi Claro, Mi Personal, Mi Movistar; foreign cards are hit or miss), on international sites like Ding with a foreign card, or in the CacaoCash app from a USD balance. CacaoCash covers Claro, Personal and Tuenti, not Movistar, at about 1,470 pesos per dollar plus a US$0.25 fee, with no DNI and credit in seconds to minutes. It works for any Argentine number, so you can also top up family from abroad.
To top up a prepaid phone in Argentina you have four options: the carrier's own app or website (Mi Claro, Mi Personal, Mi Movistar), a kiosk or supermarket where you pay cash pesos, an international top-up site like Ding or BOSS Revolution with a foreign card, or the CacaoCash app, which recharges Claro, Personal and Tuenti lines from a USD balance with no DNI and no Argentine card. All of them work for your own line or someone else's, so you can also top up a relative in Argentina from abroad.
If you just landed and are still sorting out money, our Buenos Aires money checklist covers the rest of the setup: how to pay, how to get pesos and what to skip.

How to top up in the CacaoCash app, step by step
- Open the app and tap Top-Up on the home screen.
- Choose your carrier: Claro, Personal or Tuenti.
- Enter the number: area code plus number, without the 0 and without the 15. For a Buenos Aires line that looks like 11 2345-6789.
- Choose an amount from the list of peso amounts.
- Check the Review before recharging screen. It shows the exact total in USD, including the US$0.25 service fee, before you confirm.
- Tap Recharge. You will see Recharge sent, and the credit reaches the line in seconds to minutes.
The app checks that the number belongs to the carrier you picked. If you choose Personal for a Claro number, it tells you so ("That number is Claro. Choose Claro to top it up.") instead of letting the top-up fail. Numbers you recharge are saved under Your numbers, so the next top-up is faster.
Amounts you can load (ARS)
| Carrier | Amounts |
|---|---|
| Claro | 1,000; 1,500; 2,000; 2,500; 3,000; 4,000; 5,000; 6,000; 7,000; 8,000; 9,000; 10,000; 13,000; 15,000; 20,000; 30,000; 34,000; 40,000; 45,000; 52,000; 58,000 |
| Personal | 1,000; 2,000; 5,000; 10,000; 15,000; 20,000; 25,000; 30,000 |
| Tuenti | 5,000; 10,000; 15,000; 20,000; 25,000; 30,000; 35,000; 40,000 |

What about Movistar?
Movistar is not available in the CacaoCash app today. To recharge a Movistar line, pay cash at a kiosk or supermarket or use the Mi Movistar app with a card.
Credit vs data packs
A top-up adds credit (saldo) to the line. It does not buy a data pack by itself. Once the saldo is there, you use it to buy a pack: usually in the carrier's app (Mi Claro, Mi Personal). Pack sizes and prices change often, so check them in the carrier app before you choose how much to load. The same apps show your current balance.
Tips before you recharge
- Double-check the number. Credit sent to the wrong line usually cannot be reversed. The app catches a wrong carrier, but not a wrong digit inside a valid number.
- Mind the format. Drop the 0 before the area code and the 15 before the number. Outside Buenos Aires the area code is longer and the number shorter, but you still drop the 0 and the 15.
- Load enough for the pack you want. Look up the pack price in the carrier app first, then pick the closest amount above it.
- Read the total. The review screen shows the exact USD amount, fee included. The quote is valid for 10 minutes, so confirm or start again if you step away.
What it costs, honestly
CacaoCash charges top-ups in USD at about 1,470 pesos per dollar, plus a US$0.25 service fee per order. Example from October 2026: an ARS 9,000 Claro top-up cost US$6.11 plus the US$0.25 fee. That rate is close to what a foreign card gets in Argentina (≈ 1,465 per dollar), not the crypto dollar (≈ 1,603) you get when you pay QR codes or send pesos to an alias with CacaoCash.
So for phone credit, the advantage is convenience, not the rate: it works from a foreign balance, from anywhere, at 3 a.m., with no DNI and no trip to a kiosk. If you already hold cash pesos, a kiosk is about as cheap, and for big amounts it can be slightly cheaper. Our guide on the card dollar vs the crypto dollar explains why the rates differ, and today's numbers are on the Argentina dollar rate page.
Topping up a relative's phone from abroad
CacaoCash takes any Argentine Claro, Personal or Tuenti prepaid number, not only yours. Your mother in Córdoba, your partner's brother, the student you sponsor: enter their number, pick an amount and the credit lands in minutes, while you pay from a USD balance wherever you are.
If they are on Movistar, or you would rather let them choose, send pesos instead. A transfer to their alias lets them recharge any carrier themselves and spend the rest on whatever they need, and with CacaoCash that transfer uses the crypto dollar. If alias, CVU and CBU are new to you, read CBU vs CVU vs alias explained; for larger amounts, compare options in our guide to sending money to Argentina from abroad.
Getting a prepaid line as a foreigner
Argentine lines must be registered with an ID. Under ENACOM rules, non-resident foreigners register with a passport. Claro and Movistar usually need a store visit; Personal has also let passport holders sign up online. Once you have the line, any of the top-up methods above works.
Short stay? You can skip a local line entirely. A data-only eSIM covers maps, WhatsApp and payments; see our guide to eSIM for Argentina.
Frequently Asked Questions
Can I top up an Argentine phone with a foreign card?
Sometimes. Carrier apps accept foreign cards only some of the time. International sites like Ding and BOSS Revolution take foreign cards with their own rates and fees. CacaoCash avoids the card problem: you fund a USD balance and recharge from it.
Can I top up Movistar with CacaoCash?
No. Today the app recharges Claro, Personal and Tuenti. For Movistar, use a kiosk or Mi Movistar.
How long does a top-up take?
In CacaoCash the credit usually arrives in seconds, and at most a few minutes after you see "Recharge sent".
What if the top-up fails?
If the payment goes through but the carrier does not deliver the credit, write to info@cacaocash.com with the number and the time, and support resolves it.
Does it work for contract (abono) lines?
No. Top-ups are for prepaid lines only. Contract lines are billed monthly by the carrier.
Can I top up from outside Argentina?
Yes. You only need the CacaoCash app and a USD balance. The number must be Argentine; where you are does not matter.
