A budget smartphone is a mobile device that offers essential features at an affordable price, typically ranging from $100 to $300. These phones are designed for users who need basic functionalities like calling, texting, and internet access without the high costs associated with premium models. They often come with decent cameras, sufficient storage, and a user-friendly interface. While budget smartphones may lack some advanced features found in flagship models, such as high-resolution displays or powerful processors, they still provide a reliable experience for everyday tasks. Popular brands like Samsung, Motorola, and Nokia offer various budget options, making it easier for consumers to find a suitable device.
