I’ve been having problems with my phone being stuck in 3G and not switching to 5G for sometime now which was really bugging me and traced the problem down to the ‘Smart 5G’ option.
I thought this option was to save power thus use 4G when not needing 5G but this hasn’t been the case, its not given me 5G when needed and even forced the phone into 3G so wanted to share this fix, turn ‘Smart 5G’ off

2G/3G connection every now and then falls away.
--------------------------------------------------------------------------------
I have the following problem.
Hi I have a plan with extra fast with endless online. But every now and then suddenly falls away and my connection voice and 2G/3G can I just restore it in airplane mode to turn back and pick up.
Are there more people with same problem? I have an G1. The SIM card only 8 weeks old.
I like to hear from you.
I think most T-Mo customers suffer from that, you see they have very small 3G coverage and Edge is super slow on tmobile. You must've had a faster carrier like veri$on,$print,At$T,O2, etc before. Well i had sprint before and they had some great speed and i always had Evdo, but now i only get this damn edge connection.
I had been having problems getting 4G at home and just noticed that if I turn off WiFi, 4G pops right up and as soon as I re-enable WiFi (which connects to my home network) 4G disconnects. Has anyone seen this behavior? When you think about it, it makes perfect sense, and since both are enabled to connect when the other one isn't, the flip-flop is automatic. But it surprised me.
its probably because sprints 4G is based on WIFI. or it just cuts off 4G cus you dont need it anymore
I believe it works the same way as WiFi and EVDO works on older phones. When you turn on WiFi it will use that as your data connection instead of EVDO regardless if it is a crappy WiFi connection.

Yeah, it's actually pretty cool, but if you don't know about it, it gets frustrating. I called Sprint customer service and he had me go through the battery out/in routine and go outside and try, etc. So maybe they don't know about it either!
But it makes sense for Sprint, since their data plan is unlimited and they want to avoid network overloading (are you listening AT&T? LOL). The only thing you miss on WiFi are location-based sevices that rely on GPS (navigation, some weather products, etc.).

WiFi and 802.16e aren't all that similar. LOTS of differences between the protocols.
Maybe there's some isolation problems on your device as Sprint is using their 2.5 GHz spectrum holdings for their 4G network.
4g network and 3g network both will shut off when enabling wifi. Why have 2 forms of data going at the same time? Its not gunna use both to double your speeds.
You wont lose any GPS features. Turn on wifi and load up Google Maps, it will find your location exact.
When making calls and sending text it uses 1x so you will still receive everything except for MMS. Maybe they fixed it to where you can receive them even when on wifi with the Evo, not 100% sure.
4g and WiFi are both data only connections. You don't need two data connections simultaneously so it is smart enough to auto disable one to save battery. It would also cause routing problems.
Every phone does this LOL When you switch on Wifi they turn off 2g,3g,4g etc because you can't use 2 data connections at the same time.
I'm curious why you would want 4g and wifi on at the same time?
I thought this was pretty common knowledge (on any Android phone)... And I also thought it was done for battery conservation reasons as much as anything else. WiFi's a simpler point to point connection and from what I understand it sucks less power than 3G or 4G which is constantly checking for additional cell towers in case you've moved, etc.
If you're at home or at work w/a stable WiFi connection you should be able to preserve more battery power by using it, within the settings you can even set it so the phone doesn't revert to 3G when it goes to sleep (the default setting IIRC), otherwise it does this and only jumps back to WiFi when you wake it ('till you're out of range anyway).
I agree with all the comments. And if the Sprint Customer Service guys had said, "Hey, you idiot...it's supposed to do that," then I wouldn't have posted. But the fact that he was as stumped as I was prompted me to post (we all know that Sprint gets all it's info from reading these forums...LOL).
Hey folks, I noticed that on my At&t samsung focus that the connection often doesn't switch down to edge when 3G is at no bars(tested-no data). And I know that areas I visit often have edge coverage because i can turn off 3G manually and get good reception... but any insights/solutions as to why the focus doesn't automatically switch bands/connections? radio bug?
edit: I did do the hsupa/dpa release hack via diagnosis console.
This also bugged me. In my experience this is not limited to the Focus. I encountered the same issue with the Tilt 2. It took probably a complete loss of 3G signal for the phone to switch to Edge and then even though the Edge signal had 2 bars, as soon as it got just a trace of 3G signal it went right back. Fortunately with the Tilt 2 I am able to turn off 3G and the phone stays in Edge all day long in areas where 3G os crappy. I wasn't able to do that with the Focus.

I'm having these problems as well and I also did the hack. Since then I keep getting cannot connect messages in IE. It was so frustrating that I undid the hack(?) and this happens all the time. Can someone give me the settings to make sure I restored the original settings.
Hey all so I just got the 6t and I use Verizon and noticed that there is no option for WiFi calling. I guess after searching around Verizon needs to enable it? But I'm just confused as to what needs to be done to allow users to use it.
It's a big deal for me because the reception in my house is bad. I have thick walls (wooden log cabin). On past phones my phone's would drop lte to 3g then back a lot and only way around this was to use wifi calling.
To hold me over I just dumped 200 bucks on a lte externder from Verizon (femto cell) but I thought I would ask what needs to happen for Verizon users to get wifi calling and if it would ever come down the road
I would love to know the same info for AT&T
I tried all the modules and tricks to get it working and never could. I had all settings enabled in the hidden menus and by all appearances it should have worked but it never did. I ended up returning the phone because I don't have a good LTE signal at work or my house. Loved the phone otherwise but not getting texts and phone calls was a no go.
It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.
try disabling WiFi calling that helped in my case
Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band

Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
