SUBE works offline, so an electronic payment and the balance update are separate steps: present the card to an approved activation device to apply the pending amount.
Why a SUBE top-up can remain pending
An electronic load does not necessarily update the physical card at the moment you pay. Argentina’s SUBE system works offline; the card must be presented to a device that can credit the pending value. That is why a completed payment can exist even when the card’s displayed balance has not changed. See SUBE’s electronic-load terms.

A second possibility is that the card is at its maximum balance. SUBE’s guidance published July 22, 2026, sets the physical-card balance ceiling at ARS 40,000. If a pending load would take the balance over that ceiling, the excess remains pending and can be credited as you use balance. The same guidance caps electronic loads at ARS 30,000 per operation. These are the limits stated on that dated SUBE page.
Also check that the payment itself completed. If a wallet, bank, or other payment platform shows a failed or reversed transaction, contact that provider about the transaction. SUBE’s terms say electronic loads do not expire, and its FAQ explains how to ask about an amount credited incorrectly.

How to activate a pending load
Choose one of SUBE’s three activation routes. The phone option requires a compatible Android device; otherwise, use an enabled bus validator or a SUBE Automatic Terminal.
| Method | What you need | How to use it |
|---|---|---|
| App SUBE | An Android phone running Android 6 or later with NFC. | Open the app’s “Acreditá o consultá saldo” or “Ver saldo” function. Hold the card against the back of the phone until the app reads it and credits the load. |
| Carga a Bordo | A bus and location where the feature is available. | Tell the driver you have a pending load, then present the card to the validator when instructed. Wait for the completion indication before removing it. |
| SUBE Automatic Terminal (TAS) | Access to an enabled terminal. | Present the physical card and leave it in place until the terminal completes the crediting operation. |
The app requirements and current activation options are listed in SUBE’s electronic-load instructions and App SUBE terms. The iPhone NFC function is not compatible with this app crediting method as described by SUBE, so use a TAS or a bus with Carga a Bordo instead. Not every bus or route supports the onboard option.

What to do if the balance still looks wrong
- Try an approved activation method and wait for its completion indication.
- Check the card balance using the App SUBE, a TAS, the SUBE website, or a SUBE service center. SUBE also lists the 0800-777-SUBE phone line as a balance-check option.
- Keep the electronic-load receipt. If the card received a different amount than expected, contact SUBE through the channels listed on its loading FAQ.
- If the payment failed, was reversed, or does not appear as completed in the payment platform, contact that platform’s support about the transaction.
If your registered card is lost before a pending load is credited, SUBE says to associate a replacement card. After the balance transfer, the pending load is credited as well; pending electronic loads have no expiry under SUBE’s terms.
