Do you still have a landline at home? With the prevalence of mobile phones, the use of landlines has gradually decreased. However, there has been recent online discussion about how landlines can still operate during power outages, as their power comes from the telecom provider's exchange, and you just need to connect to the phone line to make calls. Experts point out that small-screen landline phones do not need to be plugged in to operate. Nevertheless, with the development of communication software, many people have already stopped using landlines. According to data, the number of landline users is expected to continue to decline. Although mobile phones are convenient, landline phones can still be useful in emergency situations.

Do you still have a "landline" at home? Nowadays, almost everyone has a mobile phone, and the frequency of landline use is gradually decreasing. However, there has been recent discussion online about the capability of landlines to make calls without being plugged in! Some even mentioned that during power outages in typhoon days, it was the landline that kept them in contact. Experts explain that the power for landlines comes from the telecom provider's equipment, and as long as the phone line is connected, you can make and receive calls.

Landlines do not require a power supply; they can be used as long as there is a telephone line connected. Some netizens have found that indoor phones can still ring even when not plugged in. The power for such wired phones comes from the telecom provider's equipment, requiring no additional power supply. However, certain models of cordless phones or large display models still need to be charged.

Appliance providers state: "Wired phones without screens, or models with smaller screens, do not need to be plugged in, only requiring the telephone line for communication." With the popularity of mobile phones and the development of communication software, more and more people are choosing to use internet calls, leading to a yearly decrease in the number of landline users.

• Some individuals have said they have canceled their landline service: "About two to three months to half a year ago, because it wasn't needed at all, I saved that expense."
• Others believe that landlines are still more convenient in certain situations: "If cell signal is poor and you need to stay in contact, a landline would be a good choice."

The monthly rental cost for landlines varies based on region and features, ranging from about 50 to 95 yuan. According to recent changes in the number of landline customers, there were over 9.39 million customers in 2022, but it is estimated to fall to over 8.85 million by 2025, indicating an overall usage rate decrease of about 5% over two years.

Appliance providers point out that landlines are usually still used in homes with elderly residents, especially in remote mountainous areas, where landlines remain a more reliable choice due to reception issues. Although mobile phones are convenient, they cannot receive calls without power. Therefore, during emergencies such as typhoons, earthquakes, or power outages, home phones still serve a useful purpose.
