In the newport beach, laguna beach, and dana point area, AT&T works great. We're still getting a maximum of 5 bars. It'll never drop below 3 bars around here
Your lucky.
@ my house I'm usually at around -96 db while holding but my signal fluctuates vastly, from -84db to -109db.
You changed it from having 4 bars when laying untouched and 3 or below when picked up, to this more formal explanation. Where do you reside?
Newport Coast, toward Newport Coast Dr from Spyglass Hill. I still get service and good speeds so it's not big deal but ya my bars are soo low now. Talking about service on the other side of Irvine (by the 5) I drop to Edge.
