Having purchased the Fairphone 4, I was initially concerned about its compatibility with carriers in the United States.

With its easy repairability and available spare parts, this phone truly stands out. I have been using it for two weeks without any issues, and it has become the best phone I have ever owned.

An Environmentally Friendly Device

The Fairphone 4, known for its environmental consciousness, is a standout smartphone. As a consumer who is concerned about e-waste, I made the decision to purchase this phone despite the potential limitations in terms of carrier compatibility in the United States. I was pleasantly surprised to find that it works well on the T-Mobile and Mint Mobile networks. Although I had to purchase a prepaid plan from T-Mobile, the peace of mind I get from knowing that I’m contributing to saving the environment makes it all worth it. One of the standout features of the Fairphone 4 is its repairability. With most of its components being easily replaceable, this phone is designed to minimize waste. Additionally, the availability of spare parts and firmware support until 2027 ensures that this phone will have a long lifespan. Overall, I highly recommend the Fairphone 4 to anyone who shares the goal of making a positive impact on the environment.

Can’t Make Calls in the USA

It’s worth noting that the Fairphone 4 may not be suitable for making calls in the USA, despite its commendable features. This limitation is something to consider before purchasing the phone. However, one of the main reasons I chose this phone is its commitment to ethical manufacturing practices. Unlike many other phones on the market, the Fairphone 4 ensures that it does not use slave labor in its production. This commitment to fair labor practices is commendable and aligns with the values of many conscious consumers. Despite the inability to make calls in the USA, the Fairphone 4 offers an alternative for those who prioritize ethical manufacturing and want to support companies that prioritize fair treatment of workers.

Fairphone 4 Dual-SIM: The OS Sucks

Despite its impressive hardware specifications, the Fairphone 4 falls short in terms of its operating system (OS). Users have reported various bugs, including issues with call audio and camera app performance. These problems can be frustrating and impact the overall user experience. While the hardware, size, screen, and cameras of the Fairphone 4 are satisfactory, the OS requires attention and improvement. Some users have even considered switching to alternative OS options like Lineage OS to see if it provides a better experience. It’s important to note that these OS-related issues are a significant drawback of the Fairphone 4 and may affect purchase decisions for individuals who prioritize a smooth and bug-free user experience.

Fairphone 4 Dual-SIM: Fantastic!

Users who appreciate its overall performance have given high praise to the Fairphone 4. With a great display, fast performance, and impressive battery life, this phone delivers a fantastic user experience. One area where there is room for improvement is the availability of case options. Users have expressed a desire for rugged cases that can provide enhanced protection, similar to a gorilla case. Despite this minor drawback, the Fairphone 4 remains an excellent choice for individuals seeking a reliable and high-performing smartphone.

Works in the USA on 5G with No Issues

For users in the USA prioritizing 5G connectivity, the Fairphone 4 is a great choice. With seamless compatibility and no reported issues, this phone allows users to enjoy the benefits of 5G on T-Mobile’s cheapest pay-as-you-go plan. Additionally, the Fairphone 4 offers unique features such as the ability to change the battery without tools, long-term Android support, and a modular design. These features contribute to its overall success and make it a winner in the market.

Fairphone 4 Dual-SIM: Excellent Phone

Offering a fast performance, vibrant display, and long-lasting battery, the Fairphone 4 is an excellent phone. What sets it apart is its commitment to sustainability and repairability. The inclusion of a tiny screwdriver and the option to order replacement parts from the manufacturer’s website make repairing this phone a breeze.
