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.

Hey all, I know that switching from 3g to HSPA+ on the T-Mobile network Is intentional, but almost all the time between my pushing a button to send data and the device switching to HSPA+ there is usually a 20 to 30 second delay which isn't acceptable. Sometimes it doesn't even switch or when it switches no data is transmitted, which sucks if you are trying to use sip calling (VoIP), it ends up in a dropped call or about a minute of waiting before the call is actually answered. Does anyone have any solution for this or experience the same thing?
(Even now I can't post this because it won't switch... with full signal bars!)

My nexus 4 sometime does this, with full bar and the network showing HSPA+, it will take a minute or so to load a page. Even when speedtest show over 10Mb. Other time it usually work fine with the 3-5 second delay while it switch to HSPA+. I test my brother tmobile s3 side by side with my and his webpage load faster then my while my network switch from 3g to HSPA+.

I'm guessing none cares enough to answer. Or we're alone in our own world.

Fast dormancy is something that T-Mobile uses as a form of network management and also as a "battery saver". This is what your experiencing when your phone switches to UMTS (3G) when the data connection goes dormant.

I've had the delayed switch intermittently from every phone I've had on T-Mobile. It will come and go.
I chalk it up to a network issue and not a device issue.

Thanks for your answers guys, I understand it is how T-Mobile has configured their network. My only gripe is that sometimes it takes about a whole minute to switch. Thanks again.

Hey guys, got my nexus 4 a couple of days ago coming from a galaxy s3, and I notice that I never get h+ like I used to do on my s3,it only gets to H, and the Internet speed of course is slower than it I was on my s3, I'm spending time in the same places I spent before but the speed isn't quite as good, I asume it's because it's only getting Hspa but not hspa+, any idea of why is this happening? Thanks in advance

What ROM are you on?
Sent from my Nexus 4 using xda premium
Depending what ROM you're using. Certain ROMs cant distinguish the difference between H and H+ on the status bar. However, you can manually check via Settings -> About Phone for HSPA+.
I'm using the stock rom, not rooted, I checked and it says HSPA:10 never days HSPA+

The Nexus 4 is a HSDPA+42 device so you should get similar speeds as the S3 or even better with the Nexus 4 (unless you are talking about the LTE variant on a LTE network ). I don't think the S3 in general EVER showed HSPA+ as those stock devices always showed "3G" or "4G" or "4GLTE"
What kinda difference as we talking here anyways? 10Mbps or 1Mbps? Somewhere in between?
When it's saying HSPA:10 that's only HSPA and when it's idling. When you are actively using data it will show HSPA+:15 which is HSPA+ (21Mbps or 42Mbps depending on your carrier).
The s3 was the international, I'm not from the us, and I haven't measured the speed but I feel that it takes longer to load stuff, and it never shows h+ on top, only H :s, maybe it has something to do with the band of the carrier?

Like the guy above said, check manually in about phone>status to see if you're getting H+ (when you're doing something that needs internet). Also try doing a speed test with both phones and see if the results are the same or similar.
Sent from my Nexus 4 using xda premium
Well I started downloading and app and it said HSPA+:15, but it's weird that it dent say it on top, either way I feel the speed is slower than it was on the s3, I will test it when I get home to see what's going on... But it is DEFINETELY not faster

Seems my phone drops to 3g but when it says its 3g no data transfers when it says h or h+ it transfers data

You probably just have ****e service. Restart your phone and see if that clears out your problems.
When not in use, the radio switches from HSPA to UMTS in order to save power. All UMTS/HSPA devices do this, but stock Android devices like the Nexus 4 actually show this transition as a change from H(+) to 3G, instead of hiding it like most handsets which simply continue displaying 4G on the status bar. H(+) will show back up when you start using data and the radio ramps back up from UMTS to HSPA/HSPA+ in order to deliver your data more quickly.
This is standard behavior, unless you're actually having trouble using data, which is a whole different issue.
Seems like it stays on 3g when I need it sometimes. Is there a tweak to quicken then switch. Sometime t takes like ten seconds to swticj

This service is horrible. I hate to leave this phone but this sucks. T-Mobile must have no roaming agreements set up

Are you on their prepaid? if so, then you don't have the roaming agreements hence the bad coverage.

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.
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.
