FrameworkLTE Expansion Card
The FrameworkLTE is a custom Framework expansion card that provides LTE data access with a physical SIM card, enabling cellular connectivity — including calls and texts — directly from a Framework laptop. Created by community member lonersoft (Lolo280374) and published on GitHub in April 2026, the project houses a stripped ZTE MF79U LTE modem inside a 3D-printed expansion card enclosure.
LTE Cat 4 Cell Modem Card
The LTE Cat 4 Cell Modem Card is a long-running community project to create a cellular LTE modem expansion card for Framework laptops. Originally proposed by engineer Tim Taylor in October 2021, the project has gone through multiple design iterations by different community members and companies, with the most recent active effort being an ultra-compact open-source design by Filip Stedronsky (Filip_S) based on the Quectel EG95 modem module.
