Nexus 4 on 1900 and 1700 bands at the same time? - Nexus 4 Q&A, Help & Troubleshooting

I still havent got my nexus 4 yet, but it is still on the way. I just had a quick question. I am going to be using this device on tmobile. Tmobile is currently making its hspa available on 1900 band and nexus 4 supports both 1900 and 1700. So can nexus 4 run on both bands with the same sim card or is it restricted to one band in some way. It would be cool if it could run both at the same time because in areas where 1700 isnt available 1900 could be used and vice versa. Thanks.

The phone defaults to the best available band

The band is auto selected. There is nothing for you to do. Since the N4 is pentaband, it will have no problem whether you are in a new 1900Mhz T-mobile area or not.

Don't u have to type *#*#4636#*#* in the dialer and choose lte

There is nothing you have to do. Your phone will use any of the supported bands if available, 850,900,1800,1900,2100 or 1700/2100 automatically without you having to do anything.

[Q] Nexus 7 3G HSPA+ 32GB

Hi there,
I bought online the 32gb version of Nexus 7 with 3g capability.
Actually I'm leaving in Australia using it with a Vodafone prepaid microsim with data bundle and the navigation is not fast like in mine galaxy nexus i9250. First of all during the internet navigation I noticed Nexus 7 switch between 3g and H always so i checked with network widget if there are differences in connection speed with Galaxy Nexus that is working with Vodafone as well.
I discovered unfortunately my nexus 7 is always in HSPA with a speed of 700-1700kbps and my Galaxy Nexus works in HSDPA o HASPAP with a speed of 1.4 Mbit - 14Mbit or 10Mbit - 20Mbit in the second case.
So is it possible to force the Nexus 7 to operate at higer speed ?
Thank you in advanced

I have exactly the same problem. On my galaxy nexus i get hsdpa and hspa+ depending network load. With the nexus 7 3g I only get hspa. I tested with two providers and both gave the same results.
Anyone have any ideas how we can get the nexus to use hspa+?
Running 4.2.2 with 1231_0.17.0_1205
When you make this comparison, are you using the same SIM in both devices? Same APN?

Exactly same thing here!
Navigation speeds seems ok, but downloads are slower than my smartphone on the same network.
According to my carrier, my 3G (HSPA, HSDPA, HSPA+) signal is located on 2100Mhz Frequecy...

I dont know if this is possible, bit I'm thiking that the tablet only works HSPA+ on 1700MHz or 1900MHz.
Because these frequencies are the most used in USA for 3G connection.
Can someone comfirm this?

Mine gets HSPA+ on 850 MHz from Bell Canada, but apparently only regular HSPA on Wind Canada's AWS band network.

That's interesting...
But you are really sure that in your region Bell uses 850MHz for HSPA+? Because they use the 1900MHz too...
Just asking...
Is there a way to email Google about this? Maybe a Software correction can fix this, because the frequency is supported, and maybe some upgrade on baseband (modem settings) can enable HSPA+ on other frequencies, like 2100MHz...
Regards!
I have a phone that can select bands between 850, 1900 and usually when I check, the default band it's connecting to is 850. I could cross reference when I have a moment to try it out.

Thank you very much...
Could you post a screenshot of the status screen, showing the HSPA+ connection?
I'm trying to colect informations to solve this issue...

At work I'm only getting HSPA:10 but that still translates to 8200/1900 speeds. I'll look into it when I'm home.

How I wish have that speeds on my devices...
In my smartphone with HSPA+, I got 5Mbps/1,2Mbps
On the Nexus 7 (regular HSPA) 2Mbps/1mbps
Unfortunately, the only device I own which is capable of selecting individual radio bands is not cooperating anymore with the SIM card that I use in my tablet. So I wouldn't be able to tell you whether it's running on 850 or 1900. Also, I could have sworn that in the past I have seen the tablet report HSPA+, but at the moment it is consistently reporting only HSPA. Nonetheless, I am still getting exemplary speeds.

Show Which GSM UMTS Frequency is Connected?

Hello,
I have searched all over the web about how to display which GSM or UMTS bands I am connected and using at the moment (i.e. 850mhz, 1900mhz, etc), but the ibky thing I have found is to get into the phone's service menu, but every time I try, either nothing works or I receive MMI code invalid.
Is there an app that cab do this for me? I just want to know which frequency O am using in determining what other international phones can work in my area on 3g. I am on T-Mobile and I know they have been converting to the 1900mhz band for some time now, so I want to confirm for sure.
*#*#INFO#*#* does not reveal the band, and *#*#SERVICE#*#* does nothing ...
Please help.
Thank you.

Try #*#*4636*#*#

Yeah #*#*4636*#*# does nothing either. BTW 4636 is INFO on the dialer.
*#*#4636#*#* works, but that doesn't show the frequency in use.

[Q] Installed Paranoid_Android on VZ G2 and now no TMO LTE

Like the topic says, I installed the following:
[AOSPA 4.4.2 KVT49L] PARANOIDANDROID 4.0+ G2 [beta6]
And latest Gapps.
Phone works fine, but with my T Mo sim installed the best I can get is HSPA+. I am in an LTE area btw, my T Mob HTC One gets the signal just fine.
One other abnormality, the baseband version in the settings shows: "unknown" but the phone does still work
Lte bands arent the same for vz and tmo

Thats not what I've read on multiple occasions. The device does have 3 (i think) LTE bands (2 of which T mobile uses). Now I might just not be in an area where those bands the device already has are used, this I don't know.
Best I have been able to get is H+
As far as i know, tmobile only uses one band for LTE which is one of the 2 bands that att use... but verizon is on a totally different one...

Right, however regardless of if I'm in an LTE area at my house or not, the phone should still show info for things like: Phone number (currently unknown).
This is the video that explains the process of turning a Vz G2 into a T_Mo LTE capable phone:

Ok. I know here claro pr can show unknown and it still works. Iveeven seen phones with unknown or blank imei and it still works with them...

T-Mobile carrier aggregation problem

I'm having a problem with my 6p using CA - carrier aggregation. Both bands 4 and 12 are available and my phone is only using 12. I flashed an older radio that does not have band 12 and band 4 is very fast data speeds. If I flash the newest radio in the very same location my phone only uses band 12 and I see that band 4 is available using Lte discovery but I get very slow data speeds. My phone is not combining both 4 and 12. Does anyone know a fix and have you ever had this happen to you? I've even flashed factory image with no luck. Thanks

It happens to me all the time at work, it's very frustrating. Usually between 7-9am I'm on band 4 with download speeds between 40-50Mb, and after that it seems to switch to band 12 and stays there all day with downloads speed of between 0.22-1.0Mb down...it's ridiculous
I also notice that it can happen when I reboot. If I come to work connected to band 4 and then I reboot I will reconnect to band 12 and never connect to band 4 again until I leave my work area. I don't know if it's a T-Mobile issue or a software issue...It seems more like a software issue, but who knows.

It seems to be software issue because if I flash a radio for 6p that doesn't have band 12 enabled then I will connect to band 4 and have very fast data speeds. ( LTE)

It might be done intentionally by t-mobile. My fiancee's S7 Edge does the same thing.
I flashed an old modem as well to get faster speeds always connected to band 4.

I think it is because band 12 is the lower dBm signal which is stronger. I've asked for a dev to make twrp recovery flashable radio zips and no one ever did. It sure make it easier to flash radios on the fly. If I knew how I'd make one
