I got a new LG Marquee yesterday. So far I really like it, however, I have almost no connection on 3G. I have to do all data on WiFi for it to work. Today I wanted to test the GPS and started Navigation. I had GPS lock almost immediately, but I couldn't use the program because there was no connectivity on 3G. I then tried to use the browser and no web pages would load. I had a Samsung Epic and it worked pretty well on 3G in my area (90292). Any suggestions on what I can do?
You might try doing Settings>About Phone>System updates>Update Profile followed by powering the phone on and off. If that doesn't work you will probably have to call Sprint to have some provisioning corrected.
Unfortunately, I had to call Sprint Customer Service and we tried many things (hard reset, factory wipe/reset, and finally data profile update). The last one seemed to work.
Mine was doing the same thing i was ready to give the phone back i've never had any probs with there phones until now but i'm going to try what you did.. i coudln't use nothing on my phone once i left my house because i could only use the internet veiw my facebook or GPS i could on wifi
