Wireless Joint

I don't have another wifi device it works in my unlocked Moto g5 phone.

I have not used my T-Mobile phone sim in a hot spot device.

Yes on my phone unlimited grandfather plan.

Yes I unlocked it receive unlock code from AT&T

I double checked my settings and it is just like your screen shot. Still no connecting to the internet

I have a AT&T nighthawk m1 that is unlocked I want to put my cell phone T-Mobile SIM card in the nighthawk. I have tried but it won't connect to the internet. Any help would be appreciated. I'm not real tech savvy.
