That link takes me to the att store

Its OK if it is an art phone and my provider. I did have T-Mobile on thisthis phone and paid for 30 days then I realized my Sim card could be put in my S5. So it is ATT POSTPAID. thanks for your time

I will add your info in the priorb1st reply.THANKS

Thanks everyoneeveryone. I would think by now 4 years later ATT HAS more than NEXGENPHONE as the only APN. I am a postpaid customer and my glass shattered on my iPhone  8plus. Why have they not updated the android version as eell

@Schmegster

Lets see...LTE phones have been the thing since 2012... there are no generations better than that yet....so what else do you expect them to call it?
