T-Mobile LTE down? - Nexus 4 Q&A, Help & Troubleshooting

I have had the LTE fix on my phone for about two weeks now and today it is not showing up. Is 4G down in the LA area? Is anyone else having this problem?

I'm over in the IE, and LTE is going strong.

This is really weird. All the APN settings and the radio is still there. Nothing has changed except I'm just not getting 4G anymore

Have you rebooted lately? I know if I reboot, then the setting in 4636 changes to WCDMA Preferred. I have to go back and change it to LTE/GSM, then turn the radio off and back on before it will connect to LTE.
Not sure if that is normal, but that's what happens to me.

I just did a factory wipe and I rebooted everything works now. Really weird though. It happened right after I put LTE on my girls Nexus 4 and it's not working on hers right now either. I'll wipe hers when I get home I guess.

I get those speeds on occassion in chicago but that doesn't really even matter. the LTE signal seems to penetrate building better.

I noticed that, it still isn't where I need it to be but it's definitely gotten better.
These are my speeds, not the highest but I'm happy with them! I'm in NYC, btw

Nexus 4 AT&T connection lag?

Not sure what to call this really. Every since I started using the nexus my at&t hspa connection is terrible. Almost like lagging and "timeouts" constantly.
Example: I'm in Google chrome with 4 full blue bars on hspa. I type in a web address and hit go. It takes 5-10 seconds before the up and down arrows on the signal bars show up and then it starts loading the page. For 5-10 seconds it does nothing.
Same issue in apps. For example, in dice with buddies, I'll submit my move and it won't take it for like 10 seconds. I've never had this issue with any of my previous phones.
Do you guys know of better APN settings or something? I'm just using whatever stock settings there were.
I think it's a radio issue, where it disconnects spontaneously
It's annoying as hell and I'm about to sell the phone because of it.
Search the forum for the best APN. I'm on ATT with the nexus 4 and have no issues.

I concur. I not only had to change my APN, but I also had to call AT&T to make sure I was provisioned on an HSPA account.

Slowest Data Speeds on my Nexus 4

I have T-Mobile 30$ Prepaid plan with 5gb 4g data and then 3g unlimited plus 100 minutes. I have a download speed and upload speed of 100kb- 200kb. No idea why. I got higher scores on my Nexus One. coverage is perfect in my area. Is it my APN settings? I set it to IPV4/IPV6? Any help:laugh:

i've had this problem. you can check your apn settings here. but when i talked to customer support they pretty much told me if that's the speed it i get then they can't do anything about it. so if anyone else has any more info that'd be cool. :good:
Maybe u getting throttled?

I love my data speeds on T-Mobile monthly 4G...T-Mobile 3G is slow are you sure you can't get H (4G) in your area. Tmobile's 4G will actually only come on when data is being used. So I suggest browse the web for a little bit and when you see H come on then run a speedtest. But the phone idols at 3G and I didn't have to mess with any APN settings.
Edit: I am on the 70 dollar plan unlimited everything and no throttling.
No that's impossible... I only used 500mb so far...and I have a payment due in three days. I have H all the time. My iPhone 4 gets faster speeds...and that's stuck on 3G

What speeds were you getting with your Nexus One? And have you tested your WIFI speeds on your N4 are normal as you expect them to be?

Yeah they are. I got like 3-4 mpbs on my Nexus One as well as my iPhone 4. My Nexus 4 gets 200-300KB 3-5 bars H icon. I get my usual 15 mpbs on wifi so it cant be the radio on the phone..
is there a HSPA+ option that we could turn on and off. or is it when there is HSPA+ it automatically connect.

You can enter *#*#4636#*#* and change to WCDMA to GSM auto. See if that works. I have a nexus 4 and a contract plan with t mobile and I have HORRIBLE speeds. But yet good reception? Here's my screen shot
Look full bars and H

This is FULL reception. I know its tmobile because I get 12.00 Mbps for about 5min / 4 times a day, if I'm lucky

Even after a month i still have these issues. Is this a defect on the Nexus 4? I've had three replacements and it still persists.

No but what would that do xD?
Confirming that I'm having the same problem, on at&t. My Nexus 4 gets terrible speeds compared to my 850 Mhz Nexus One and my One S. Same SIM and APN on all of them.
It's also ridiculously slow to switch the data connection on (read: to show H+ in the status bar or start showing the up and down arrows.

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.

Random Signal Loss

Hi,
Not sure why, I'm facing random signal loss. Particularly when the phone sleeps.
I'm using Sentinel ROM and Air Kernel.
This has been happening in the past week and my other dumb phone on the same network with another sim card always has signal.
Neither the ROM or Kernel was updated recently.
What could be the problem?

Any chance your Nexus is looking for 3g signal where as your dumb phone is on 2g?

Getting ready for 4G?

HI, the three network in the UK is rolling out 4G this weekend, what rom do I need to flash my nexus 4 with to get it working ???!!....I wan't super fast lol !!!!!!!
I think it's only starting in like 3/4 cities if your lucky enough to live in one of the cities. Also nexus 4 only supports one band on 4g if your also lucky enough for three to be using the supported band.

itll work on the n4 only if its band 4 lte, and no other frequency for lte. and its not about flashing a rom, its about flashing a hybrid radi, having the right apn, and changing the phine info to lte/gsm. there are threads that explain how to do it.
Yes I live in London.....but since updating to the latest 4.3 I can no longer select 4g LTE in the service menu. How would I find out if three is using the correct band !????

for 4.3 the option is in the phone menu, . and you need to ask them what band they are using.
Yes but if I select LTE it just goes back to CDMA ....!? Goes anyone know the three 4G APN details !? What band goes it need to be to work !??? Sorry for all the questions lol

it goes back because you need to use either the .27 hybrid radio or the .33 hybrid radio. google disabled lte for 4.3, and you cant enable lte in the settings unless you are using one of the hybrid radios.
After a quick search its 800mhz band is that ok !??
So it won't pick up Three mobiles 4G

nice rationalization, but not true. the chip works great, everything works. and since switching over to lte permanently, ive been seeing 6-7 hours screen on time regularly. imagine this, when you download things it takes time for it to finish downloading, especially large files. the slower data speed, the longer it takes. the longer it takes, the more battery is wasted. on lte, i average about 30mbps download speed, so downloads finish in seconds. so less battery is wasted. i download 2gb games from the play store in about 13-18 minutes. the newer lte chips are much better on battety than the old days, better than hspa+, hspa, 3g, and 2g.
How can that be possible ? The LTE chip in the nexus 4 has no antenna or amplifier :/ hmm I'm baffled

doesnt need it? whatever it is, you dont hear complaints from lte users here in the states(mostly tmobile) about data signal or data speed for sure. and about battery.

Battery life is the same with LTE enabled. My N4 has it enabled my wife hasn't let me to it to her's yet and our battery life is the same, but my data is much faster than her's. I get LTE signal with my N4 in the same places as I do with my Galaxy Tab 2. So I would say it works perfectly fine. Yes I am on T-mobile in case anyone was wondering.
3 UK is going to use LTE band 3 and 20 only, so the nexus 4 will not support it (unless Google is going to release a Nexus 4 LTe version, which is pointless because you should get the Nexus 5 anyway.)
