Incoming Tests from non-ATT & iPhone users not coming in since port from Google Voice

Since I ported my number from Google Voice to AT&T I can not get any texts unless it is a iPhone or on AT&T Wireless.  Reset the phone, reset the network, AT&T reset the network, tried a new SIM card and so on - have. request in to AT&T.

It is not the phone so it is something with AT&T - I used this phone with another number on AT&T and ported my old number to Google Voice.  I have read it may be the text routing has a problem with my account. 

No idea but even texts from a bank, etc to confirm info on my computer to text me does not work as well...so hase to be a text from AT&T or an phone.  I can send texts to anyone - just not receive.  I can call and receive calls from anyone as well.
