There is a handling fee for purchasing funds on mobile phones. No matter through what channels to buy funds, funds that need to charge fees have to pay fees, but they may be purchased through different channels, and the discounts are different. But it's basically not free. Fee-free funds generally only have Class C shares of money funds and funds.

In addition to subscription fees and redemption fees, the fund also has management fees, custody fees and sales service fees. The handling fee mentioned above refers to the subscription fee. Class C shares are exempt from subscription fees, but they need to pay sales service fees.
