ESP32 SIM Module 4G LTE

Hello everyone, I have an important task to make possible the transmission of data from ESP32 via 4G to the cloud. I am having difficulties finding the right LTE modules , since even those that I found do not have dev kit (like pins from where i can get connected)they are just like small chips What do you suggest to me : 1.Is there any good resource about LTE Cat M modules, how to interface ,the needed libraries Sorry for the confusion but let say I am a newbie in this topic.
