5 Ways to Earn Extra Income Through Your Phone: A Detailed Guide for Vietnamese Users

Since the comprehensive change in business operations, digital technology has become a pillar of many industries. Now, with just a smartphone, you can participate in trading activities, fill out surveys, or even run online businesses without leaving home. Making free money on your phone has become a popular trend and a useful industry of the modern era.

Three Types of Income-Generating Apps on Phones

Type 1: Task Completion Apps

This is the simplest form of free earning on mobile phones, requiring no investment capital or professional qualifications. This model asks you to perform small tasks such as:

• Answering online surveys
• Inviting friends to install and register the app
• Watching ads and answering related questions
• Participating in simple promotional events

Each completed task rewards you from 5,000 to 100,000 VND, or provides phone top-up cards depending on the difficulty of the task. However, this method requires a lot of time and effort but offers relatively low income.

Type 2: Financial Investment Apps

These apps are platforms for transactions from banks and securities companies, allowing you to:

• Open savings accounts directly within the app
• Conduct stock transactions without visiting a branch
• Invest in various financial assets (stocks, indices, cryptocurrencies, commodities)

Earnings rates per channel:

• Bank savings accounts: 4% - 7%/year
• Stock trading: >10%/year
• International asset investments: depend on the market

As income increases, the knowledge and experience requirements also grow. You need to understand the market well and have analytical skills to optimize profits.

Type 3: E-Commerce Apps

This method allows you to open an online store with low initial capital. You only need to:

• Create a storefront on e-commerce platforms
• Upload products you want to sell
• Wait for customers to place orders

Vietnam has many different e-commerce platforms, enabling you to sell on multiple channels simultaneously to increase customer reach. For each successful transaction, you must pay a commission of 5% - 20% to the platform. Income from this method directly depends on your sales ability.
