4g available but not connecting

I have 4g turned on and available but it never connects. It just says 3g above the connection icon. How do I get it too 4g? Is it a phone setting that is wrong or a system setting with Sprint? Should I try taking the battery out and reseting?

Distinguishing between 3G and 2G connectivity

I am using a flashed Epic 4G on the Page Plus network. Whenever I have a data connection, the 3G icon appears on my phone. Does this 3G icon refer to true 3G (i.e. EVDO), or does it include 2G speeds (i.e. 1xRTT) as well?
Are there any indicators out there that can distinguish between 2G and 3G data connectivity?
On the stock framework for Epic they use the 3G icon for 1x and 3G connections. Many custom ROMs/themes have a proper 1x icon in them. Also, you can download Network Info II from the market and it'll show what mode you are in under "Net Type:" about halfway down the screen.

[Q] Switch from 4G to 3G

I have an E980. Signal keeps on dropping mainly because of the 4g connection having low signals. Couldnt find anywhere the 4g to 3g settings.
On KK 4.4.2. How can i switch settings to ONLY 3G or perhaps limit it to ONLY 2G?

LG D855 takes time to connect to 4G

I have the following issue with my D855:
When I reboot or power on the phone it display the search for network icon for few seconds and then it connects to H+. After an hour or so it connects to 4G. All the phones I used connect directly to 4G. I have 4G coverage (when it connects I have full bars), compatible 4G sim (works great in other phones) and carrier settings(set up and verified by Vodafone representatives). Also while on 4G when I connect to WiFi it searches again for network and when I turn off WiFi searches again for network and happens the same(H+ and after an hour I have 4G)
Any ideas why this happens?

how to lock network to 4g?

I have unstable 4g network at home, so my phone refuses to use 4g connection and it choose 3g.
I know *#*#4636#*#* and choose lte only will do the thing and it works but several times later it switched back to 3g (H/H+) and when I check it back it turned to Lte/gsm (Pre) again so I think I have to find another way.
It frustating me, since I just have 4g quota besides 3g.
