I have spent so much time on Twitter, voice and AT&T forums that they have credited my bill some for the hassles.
Here is what I believe:
It is the quality of the upload cellular signal.
Download an app called "Coverage Map". Turn off WiFi. Open the app. Click the alarm clockish looking icon at the top and measure the signal.
In my case at my house in the heart of Silicon Valley I am getting .1mbps up AND down. POINT 1!
When I go 5 blocks Southwest, two bars, no issues.
Now, want to try something bizarre?
- Open an image in your albums and get ready to message an Android friend.
- Put the phone flat on your desk.
- Take a 12-16 OZ filled bottle of water. The plastic bottles. Put it on the desk upright at the top of the phone just above the ear speaker slot.
- Turn ON airplane mode
- Wait 30 seconds - maybe 45.
- Turn OFF airplane mode
- Your phone will search for the cellular network. In my case I get 2 bars
- Immediately send your image
- After about a minute give or take the phone will drop signal strength and will fail to send images again.
Now, maybe that is just me. But it works when I get frustrated enough or MUST send an image via MMS to an Android friend. Apologies if any of this posted in the previous 8 pages. Have not read that all in a while.
