No signal.. what am I doing wrong?

Just received my preassembled 4G unit… yey! Charged it for two hours… inserted sim… ran through the setup… everything passed except for sim test 3/3. Updated firmware… factory reset… setup… same thing. Stuck on “loading” on top. Confirmed working T-Mobile sim card. Ting card same issue. Inserted sim exactly as shown by both the built in setup visual and the online get started instructions and confirmed with a few previous posts on this forum. I opened up the phone and inspected and reseated all the parts just to make sure. I’m in an area with strong signal (NYC). I tried using the phone in clear skies, restarted but nothing. 911 works though (sometimes). I successfully restored the firmware from CircuitBlocks but no sim change. I’m stumped.

Antenna plugged into top most port.

Everyone seems to have the same problem, but everyone just talks about going outside or switching services. I haven’t seen one difference in what people are doing. I have done it all and every phone company I talk to say the same thing. No one can get my makerphone to work.
