Hello all, I’m really new and I have been trying to get this hackersbox kit working for a while now, I have been following Ben’s tutorial and Lib GitHub - hologram-io/hologram-SIMCOM I have my setup shown below. however I can’t get this to work for the life of me. I get a Cellular connection failed error. however on the hologram side in the datalog I am getting a socket error: connection timed out log that is also pasted below with the sketch code. any help or guidance would be grateful on how to fix this and work!
using the hologram-SIMCOM-0.4.0 Lib
