I have a galaxy s2 running Android 2.3.6 gingerbread. it's actually a us cellular phone but that carrier isn't listed. anyway, when I an at home I have very low service connection. a lot of the time when I'm trying to send a text message, I get the error message 'code 7: network problem. other times the phone tells me that the text failed to send. this is annoying enough, because then I have to resend. but it's made worse by the fact that the text did indeed send but only some of the time. so I either risk the recipient receiving multiple copies of my text or none at all. why can't my phone simply inform me that there is currently no connection and Waite for sufficient signal to send like all of my old phones have done? and why does my phone give me incorrect information about my texts?
