There are no reliable ATMs available along the Upper Mustang trek route itself. Functional ATMs are only available in major cities like Kathmandu and Pokhara. Jomsom, the entry point for Upper Mustang, may have an ATM, but it is often out of service, out of cash, or does not accept international cards. Do not rely on it.
The trek is entirely cash-based. Teahouses, shops, and vendors accept only Nepali Rupees, and credit cards are usually not accepted in smaller villages. Carry enough cash to cover extra expenses such as showers, device charging, and hot water.
