Finally a 4G network-compatible pHAT for the Raspberry Pi! This pHAT accepts a 1.8V/3V sim card and supports a wide range of LTE Cat-4 network bands alongside 3G and 2G support, including phone calls via AT commands and SMS functionality!
Speeds of up to 50Mbps Uplink* and 150Mbps Downlink* are possible on a 4G network. The pHAT supports GNSS positioning via the GPS, Beidou, GLONASS and LBS Base satellite systems and includes an onboard audio jack and audio decoder support making telephone calls.
The onboard USB Hub chip provides 2x USB 2.0 connections and a USB solder pad for adding an additional connector.
It's possible to create a 4G/3G wireless router with this pHAT and Raspberry Pi OS or OpenWRT (with configuration) - turning your Raspberry Pi into a WiFi hotspot for other devices to access the sim card's network.
Included in the package is the pHAT, an LTE antenna, GPS antenna, USB cable and dedicated "pogo" pins for connecting a Pi Zero to the pHAT without the need for USB connections!
* Idealised data rate - actual data rate depends on factors like network coverage, traffic congestion, base station condition etc. Your mileage may vary.
Note: Raspberry Pi not included

4G pHAT for Raspberry Pi - LTE Cat-4/3G/2G with GNSS Positioning
Works with both nmcli and qmicli, although all internet posts advise qmicli I found using nmcli & a bash script to take down the wwan and enable raw
(i.e. "echo 'Y' | sudo tee /sys/class/net/wwan0/qmi/raw_ip")
Works well for me
