Txt and calls work good but forget data. Their ludicrous speed is half that of Verizon. My wife is still on Verizon parent and her download is 21 Mbps. I'm on US Mobile and mine is 7 Mbps at best but during 90 percent of the day it's below .5 Mbps. I think it's due to deprioritization on Verizon towers thought they won't admit it. It's mostly unusable. Customer Service did their best but blamed it on network problems in my area but I know that isn't the case because I swapped the sim card with the wife and got the same results. 20 Mbps with her card in my phone and 4 Mbps with the US Mobile sim in her phone. These numbers were better only because these test were done at 4 AM. Like I said during the day the best I got on US Mobile was .67 Mbps.
