    It was working great now it dropping calls and receive calls to....try to dial out it a long delay then it disconnects. I'm using ATT APN settings but I don't know if its right. If anyone has a suggestion I would appreciate it. Thanks I'm a noob on this now I'm stuck. My WiFi works great but the calling messed up.

    try this app https://play.google.com/store/apps/d...tweakker&hl=en but in my experience you shouldn't have to do anything with the apn when it comes to calls at least i dont have to with my straight talk sim in my droid maxx also my calls sound fine

    on app click AT&T then click LTE i know you wont get lte only hspa+ but i think thats still the apn you have to use
