A one way pager device with a small screen to display pages that runs on 4G Cat1 modem for connectivity. The modem has to be approved for USA market. The device can be up to 2.5" X 3.5" max size and features a rechargeable battery through a USB-C port at the bottom. It will feature an LCD or EPaper display and about 6 buttons for functions. The buttons need to be recessed so that they do not get pressed when in the users pockets. It should run on an ESP32 or similiar processor that can be flashed with our firmware through the USB-C port used for charging. It should feature a 4G Cat 1 modem for cell connectivity that our firmware will use to download pages to display to the user. It will havea small beeper and a vibration motor to notify the user of a new page.

I am attaching some pictures of similiar pagers that do not use 4G for connectivity. Please not this is only for reference and I would like to have a bigger and better display as well as 4G connectivity.
