i only glanced over your initial post so i missed the part about you having problems with 4g and 3g.its kinda safe to assume you would also have them with boost.
I don't know about that. I've had both Boost and Virgin, and though Sprint is the parent company for both, I've had different experiences with each. Of course, this could be because I've used different phones with each carrier, and besides for the network, the phone affects your experience too.
That said, I've always had better reception with Boost, for some reason. With Boost, I could make calls from almost anywhere in my house with rarely any static or cuts, or dropped calls. Oddly, though, my 3G speeds were horrible. Pages took AGES to load, and it drove me crazy, since I browse the web a lot on my phone. I don't know if that was an issue with that particular phone model, though (Marquee). When I was with Virgin earlier, and again now, my call quality is not that great always when I'm at home. I have to move around sometimes to be able to make a call and hear it well. The 3G, while nothing to brag about, is very noticeably faster than Boosts. (In my personal experience.)
I've asked many CS reps about the differences between Virgin and Boosts networks, and they may not be exactly the same. I don't know if this means that they use the towers in a different way or what, since I don't have much knowledge or experience relating to how these things work, but many of them have told me that there are some differences between the networks.
The newest radio has completely fixed my phone. Went from having constant error messages, calls wouldn't receive, calls wouldn't send, texts wouldn't receive or send to having a phone with zero problems. Since changing the radio and pri, my phone has worked perfectly. Zero missed calls, not one problem making a call, every texts sends immediately, every text receives when it should. Even in terribly low service areas.
I highly recommend doing the s-off procedure and making these changes.
I have not been receiving the error with texting too often lately, but I am still missing a lot of calls. Hearing this still makes me want to go s-off and flashing the other radio, but I'd have to find a really good step by step explanation or video with instructions. I'm just reluctant to try it myself.
