I have a lg optimus g pro phone that is at&t unlocked. When I insert my tmobile sims it works fine. I tried inserting a sims card for h2o wireless and airvoice ( both are mvno that use at&ts network), and neither one work.
I have a tmobile unlocked LG V10 and again the h2o wireless and airvoice wireless sims cards dont work.
I tried both sims on a Samsung Galaxy Grand Prime (Metro PCS unlocked), and the sims card did work.
What gives?
