I just recently got my Nexus 4 and decided from the get-go to use Straight Talk. I had never used this service before so I didn't know what to expect. After I got the card, I changed the APN settings like it said to and it seems to connect, but my connection is awful! I have full bars most of the time and I get the little H at the top telling me I'm connected to the network, but a lot of times when I try and connect to Facebook it just keeps saying I have no connection, and there's a lot of times when I try to load a webpage, the text will come up, but no pictures, or else it will say it can't connect to the proxy server. Does anyone else have this problem? I am so disappointed with this service. I was really looking forward to having the faster HSPA+ service compared to Sprint's 3G, but this is worse! I'm not sure if did something wrong with the APN settings or what, but if that was the case, I would think it wouldn't connect at all. After my month of service is up, and if I'm still not having any luck, I may switch over to TMobile's value plan to see if they're any better (although going by their coverage map for my area, I can't see how it could be).
