I have VERY POOR reception on my Blackview BV9900 pro in this entire area of New York State, and NO reception in my own house. (I get 1 bar of 3G outdoors.)
I am with Consumer Cellular, which uses the AT&T infrastructure.
I have been on the phone with Consumer Cellular for almost 2 hours (so far); the access point names needed to be changed, but that did not help. I have also working in the steeple of my church, which is FILLED with cell antennae of various carriers (including AT&T), but could not make calls, even though I had 4 bars' reception.
I downloaded an app to this phone via WiFi to test signal strength; it reads between -90 db to -140 db, and usually -110 to -120 db. I don't know whether it's actually the phone or the (distant) cell tower.
I had no such issues with my iphone 7, which was on Verizon; but both Blackview and Verizon have told me that the 9900 pro is not compatible with that carrier.
I have tried calling Blackview in China, but I can't get through. They have not yet answered my e-mail.
What else can I check, and what settings can I verify?
Can you definitely rule out errors or interference from the provider/carrier?
Have you already tried a different SIM card in the Blackview to check if the reception problem still occurs?
