Introduction
In 2023, the concept of turning a laptop into a mobile phone might seem as futuristic as it does far-fetched. Yet, the ThinkPad T480, a model renowned for its robustness and versatility, offers this possibility. With clever hardware and software modifications, this laptop can not only make calls but also send SMS and connect to the internet via mobile data. Let's dive into the process that transforms a simple laptop into an all-in-one communication device.
Why the ThinkPad T480?
The ThinkPad T480 is a popular choice among professionals for its durability, power, and features. Equipped with a SIM card slot intended for an LTE modem, it is already predisposed to mobile connectivity. However, to function as a phone, certain modifications are needed.
Necessary Components
- Quectel EG25-G Modem: This modem, used in the PinePhone, is compatible with the ThinkPad T480. It runs on an embedded Android system that allows call and data management.
