In an era dominated by smartphones, parents are caught in a dilemma: they want their children to have the freedom of independent communication, but also worry about screen addiction, stranger harassment, and inappropriate content exposure. The recently popular Tin Can retro WiFi landline in the US has set a new benchmark for teen communication with its"screen-free, safe, and pure voice" positioning. Now, Kaer, a professional brand focusing on the SIP field, launches custom SIP WiFi phones tailored for primary and secondary school students. Why can these phones become a trusted choice for parents? How do they combine retro charm with intelligent technology? Let's explore the unique value of Kaer's custom SIP WiFi phones.
Kaer's custom SIP WiFi phones inherit the classic appearance of retro landlines, reminiscent of the wall-mounted phones in 1980s kitchens. This nostalgic design not only appeals to both parents and children but also abandons the cumbersome functions of modern smartphones. Unlike devices filled with apps and games, Kaer's phones focus solely on voice communication, allowing teens to focus on real conversations without screen distractions. As a brand specialized in the SIP field, Kaer equips these retro-style phones with a powerful intelligent core:
No need for traditional phone lines or jacks, connecting to the internet via WiFi for stable calls, perfectly adapting to modern home and school network environments.
Relying on mature SIP technology, the phones deliver clear call quality, low latency, and strong anti-interference capabilities, ensuring smooth communication whether chatting with friends nearby or connecting with distant relatives.
Supports emergency calling (which parents can enable or disable as needed), adding an extra layer of safety for children's daily use.

Safety is the top priority for parents when choosing communication devices for their children. The customized Kaer SIP WiFi phone adopts Kaer's self-developed security solution and has upgraded the protection system:
Approved contact management: Parents can easily add, delete, or modify approved contacts through a dedicated companion app. Only authorized relatives, friends, or classmates can make calls to the phone, completely blocking spam calls, scam calls, and stranger harassment.
Quiet hours setting: According to children's schedules, parents can set quiet periods (such as bedtime or study time) through the app. During these times, incoming and outgoing calls are disabled (except for emergencycalls if enabled), ensuring children's rest and learning are not disturbed.
l No internet access or app installation: The phones have no screen and do not support internet browsing or app downloads, fundamentally preventing children from accessing inappropriate content or becoming addicted to games.
Kaer started in 1996 and is now a global leader in communication terminals and solutions. Kaer has over 28 years of experience. Kaer makes stable, smart, and efficient products.

One of Kaer's core advantages is its strong customization capability, which breaks the homogeneity of traditional communication products. For primary and secondary school students of different ages and usage scenarios, Kaer provides a variety of personalized options:
Appearance customization: Choose from a range of colors (such as fresh pastels for primary school students, simple and stylish tones for secondary school students) and shapes (portable small models, desktop decorative models, etc.) to meet children's aesthetic preferences.
Function customization: According to actual needs, add or adjust functional modules such as call recording, caller ID, and speed dialing. For example, schools can customize group call functions for class communication, while families can opt for simplified operations for younger children.
Batch customization: Suitable for schools, communities, or educational institutions, offering preferential policies for bulk purchases and supporting customized logos or patterns to meet group usage needs.
Kaer's custom SIP WiFi phones not only solve parents' safety concerns but also promote teens' independent growth and social development:
Cultivates independent communication skills: Teens can independently make plans with friends, chat with relatives, or seek help when needed, enhancing their sense of responsibility and communication abilities.
Promotes in-depth social interaction: Compared with superficial online chats or video calls, voice communication encourages teens to express their thoughts and feelings more thoroughly, fostering genuine friendships and family bonds.
Delays smartphone dependence: By providing a dedicated communication tool, the phones satisfy teens' desire for independent connection while delaying their access to smartphones, allowing them to enjoy a more pure growth period.
