[Q] t-mobile nexus 4 wont hold hspa+

Just got my nexus 4 yesterday. Love it. But the phone is jumping wildly between 3g and hspa+ in a service area that my note 2 had no trouble holding a 4g signal. wondering if this is a Sim card issue, or if anyone else is having similar problems?

Yes, that is how its supposed to work. Carrier branded phone just don't show the change in the status bar. It is functioning the exact same way.
Nothing to worry about.

Just a heads up, the N4 doesn't show a H+ logo but just the H.
Dial *#*#4636#*#* and make sure your network says HSPAP

It's jumping between hspap and umts. Driving me nuts!

It will only switch to HSPAP when needed otherwise it will stay on umts in order to save battery life. No worries this is normal

Your note 2 is doing the exact same thing. All gsm phones do this. It idles on 3g and when data is called it switches to hspa.

T-Mobile makes the icon for both UMTS and HSPA+ the same icon that's why do you not see it change. Google makes the icons the way the network mode is.

That makes sense! Thanks so much for the help.

[Q] How to check for LTE signal?

Hi,
Before messing with my Nexus 4 (running rooted stock 4.2.2 with Franco Kernel M1), is there a way or a specific app to check for LTE signal in my area?
Thanks!

There is no app I know of that can test for a signal your phone isn't set to receive, you'd have to set it up for LTE first. And if you don't live in one of the 7 major cities T-Mobile just turned LTE on in or in Canada then you don't have LTE you can use anyways.

With Verizon you can check for their list of LTE coverage and find out if its in the area and go from there. Its almost everywhere now but back in the Thunderbolt days lots of people did that.
A quick Google search would get you started.

Verizon's current LTE network isn't compatible with this phone. They eventually will build out their existing LTE network using AWS but that is a long way off and it still most likely won't work with the Nexus.

I guess I will have to do some testing. I live nearby the T-Mobile HQ , still not officially covered by LTE but I saw an article by OpenSignal stating that there was some LTE activity nearby...

Open Signal is a crowd sourcing app and relies upon user input to give data about available towers and unfortunately no one in my city has used the app so there isn't any tower data available. So not really sure if it can give useful info as to if a tower has LTE, HSPA+ or whatever else may be around. If you live near T-Mo's Headquarters it may be worthwhile doing the LTE fix just to check as it can always be reversed.

Flash the. 33 radio set up apn and go into phone information choose network type lte and run speed test

FYI just because you are in one of the launch markets doesn't mean every tower has live LTE yet so if by have everything set up and you're not getting LTE doesn't mean you did it wrong.

[Q] Sprint 4G LTE Connection Issues

I know for a fact that Sprint's LTE works in NYC because I've used it before. Since I've exchanged my S4 I haven't been able to connect to LTE at all. I've even checked ##3282# and it says LTE is enabled and I've gone to settings>more networks > mobile networks>network mode and have CDMA/LTE/EVDO checked off. What could possibly be the issue?

Have you tried updating your PRL and profile yet? Menu/settings/more/system updates
****'ll Buff Out

I'm in the NYC area and lte is spotty at beat. Hell, I usually get it in my house but sometimes it will drop for no reason, than it won't come back up for 5 to 10 minutes.
There are times when I'm riding the train and there is a 4G signal but there's no connection to the 4G network.
Does your show 4g on the screen at all?
Have you checked the Sprint forums for NYC?

Oddly enough I didn't think to do that. I'll sww if it works this weekend. Contacted sprint too and they refreshed the services on my account. They said if it doesn't work then let them know.

I did this and when i check my LTE shows as disabled. Is there anything i can do to turn this bad boy on? I used to get 4G at my job site with my Evo 3D and now i don't even get 4G with my Galaxy 4S. I called Sprint and they told me is not a good service area but i don't bite it cause i used to get full bars on 4g and now nothing.
Any ideas guys??

The Evo 3d used wimax not LTE. This phone is LTE not wimax. Do you even have LTE in your area yet. Most places don't. Go to settings, connections, more networks, mobile networks, network mode should say LTE. Make sure your prl and profile are up to date if you are in a LTE area.

I checked and LTE was selected, i guess i will just have to wait until Sprint updates their 4g LTE network range

Why aren't I getting LTE?

According to this map http://ltemap.org/tmobile there are LTE towers in Carrollton and Garland, which means I should be getting LTE in the Plano area. I have the .33 radio flashed, the APN right, and set to LTE/GSM but I'm still not getting LTE? Do the tower signals really not bleed into Plano or am I not doing something right with my phone? I'm on Carbonrom 5/25 nightly. Thanks

You also have to enable LTE on your nexus, unless you jump through hoops, it has to be done every boot because the device resets itself to wcdma preferred. Dial *#*#4636#*#* and hit phone information. Then scroll down until you see a pulldown with "wcdma preferred" and change it to gsm/CDMA/LTE. It then will take good 5 minutes to connect usually. After that initial long time, it usually connects pretty quick if you lose signal.

Maybe they are still testing? Back in March I ended up enabling LTE on my nexus because DC area was supposed to have it up and I got LTE at my house, just no bars to go with it. So when I would test, it was around 7mbps or would drop the signal, would not work anywhere else really, and was spotty. I disabled it and the. In early may decided to try again. Now, anywhere I go I get really good LTE speeds, signal rarely drops. I would say that I'm connected about 95% of the time, and I'm up and about the city a lot, or Virginia even.

You also need an LTE enabled SIM, and if you already have one, you may need to sort things out with the carrier. I know some my American friends had trouble getting LTE to work on AT&T using Blackberries imported from Canada, even though they had LTE sims and LTE plans - they had to call up AT&T and jump through a few hoops. Also at least on AT&T and Canadian carriers, prepaid plans aren't allowed to access LTE (lame) so if you're on prepaid that could be the problem. I don't know anything about TMo, but I'm guessing they may have similar bureaucratic BS to AT&T.

[Q] network mode changes by itself. Should it do that?

Im running cm 10.1.2 it works great I live were tmobile has lte. so I flash LTE radio and that works great. my apn is tmobel us LTE and my preferred network mode is lte/gsm/wcdma. Sometimes when I drive outside lte coverage zone or in on a weak spot my preferred network mode will change to csm/wcdma. Is this normal? I was driving and I just lost signal the other day Im guessing this is why. I got a screen shot of a app that shows I get lte or hspap with lte/gsm/wcdma. Should I not get both hspap and lte with this setting. Im guessing the phone could not get lte so it changed the profile? Can it do that?. When I was out of the coverage area tried to change it back to let/gsm/wcdma but it defaulted to csm/wcdma.. On reboot it defaults to lte/gsm/wcdma. so i know its working thanks for reading my thread.

I'm pretty sure that is normal. My phone does the same.

So when your phone changes profile when it gose into a lte zone dose it drops signal or any thing?
I want to say mind dose for a second as the profile changes then if I go back into a LTE zone it will change back. But im not sure as I have only been running this build for a few days and I mostly stay in a LTE zone.

Yes basically disconnects for a sec then changes.

Just wondering why that is? does lte/gsm/wcdma not support hspap? Because my app screen shot told me on that profile i get hspap and lte .

I'm not really sure. But I do not understand why the nexus 4 handles this Network change so slowly. It's annoying at times.
