Does it happen everywhere that you go or just where you live and work? You may be able to use Volume control + to mute system volume which may prevent you from hearing the notification, if it is not controlled by notification volume.
I have only had the phone for less than 24 hours, so the only places I've really been are home and work. If it helps, I was also getting the error whilst traveling to/ from each place. I only know this because I can safely check taking public transportation :-)
I take a bus.
The thing is, though, I don't care if it goes into roaming. The sprint covergae is so patchy here anyways, I NEED it to go into roaming so that I can make a call from my house. All I want is to turn off that dang notification because I've already selected the option that tells the phone that I want it to go to roaming for voice and data, with the roaming guard being off. Let's just make that little beep/chirp noise go away without making me put ALL my notifications on silent. It is absolutely inevitable that I will be in roaming, and that is fine- I selected a plan to (supposedly) account for that.
Is the volume of the Beep/Chirp affected when you adjust your notifications volume? of so I may not be able to help avoid it. if not then volume control + may allow you to mute system volume to avoid the sound
I do not believe it is affected by the notifications volume. I will have to test it next time it happens. What is volume control + and how might that one help? And have you heard of this issue with anyone else/could it just be my phone?
Volume Control + may help because most android phones no longer give access to "System Volume", most only see notifications, alarms, media, and call volumes.
