I have done that a couple of times. I don't wanna call Verizon cos I may get the "we can troubleshoot your phone because you are running a non-verizon ROM'.
Is there any setting in Mobile networks that can be adjusted for better performance?
well,im not familiar with verizon VM,so i have no input on why that may or may not be working. maybe you need to use different gapps? or download google voice and/or voice search,or something else from the market?
on your signal strength... what are you using to determine that your signal is less than before? the signal bars on your phone? the db/asu numbers in /settins/about phone/status? download/upload speeds with a speed test app? if so what app? tested on stock rom and cm7?
the best way i think for you to troubleshoot is to load up the mr2 OTA rom and check the above things,check the DB,do some speed tests,etc. if the numbers are still not what you think you should be,i guess its possible you have a hardware issue,stay on that stock rom and call verizon and let them "troubleshoot".
if you find verizon VM to be working,and faster download speeds,higher db,etc.,then you can chalk it up to simply cm7 and your phone dont get along for some reason
you could try some of the stripped froyo/gb sense based roms(assuming you dont like sense since you went with cm7) and try all your tests again. repeat until you find a rom you are happy with
and again,make sure youre not placing too much importance on the number of bars beside the battery icon. perfect example: right now i only have 1 signal bar on cm7. but when i check signal strenth in settings,i have 83db wihch is typical of what i have here in my house. on a sense rom i may have 3 or 4 bars.
Having almost same problem. my 4g hardly connects, and I'm getting only 1x 80 % of the time, after flashing different roms. I tried the link above with no luck. My wife's TB is stock and has 4G every where we go.. Any ideas?
is your cover missing,damaged or broken? what rom are you on? we really need more info before we can try and help.
