[Q] connected to edge instead of hsdpa, how can i prevent that?

hello
i've been googling this for a couple of hours now and i cant seem to find how to solve my problem
i was with my gf today, she has a S3. we are both connected to the same network operator. my signal was E , hers was H .. i went to system settings->about phone->status on both phones and compared signal strength and it was about the same.
my brother's iphone 4s almost always have much faster internet when i'm connected to edge (that means he's not on edge) - he's also connected to the same network operator.
its driving me crazy , why won't my cappy stay connected to hsdpa when its possible? how can i change that ? (WCDMA is preferred, baseband selection is automatic)
i'm using I9000XXJVT modem. was using slim bean rom 4.2.2 build 2.5 (now i'm on build 3) . unofficial semaphore kernel.
about my network operator technology from wikipedia (its a virtual operator):
"Its network is an HSPA+[citation needed] network in the 2100Mhz band, with roaming also available on Cellcom's 1800Mhz GSM[6] and 850Mhz/2100Mhz HSPA+ network."
any help would be appreciated.

The Captivate's Network Frequencies and Data Type: GSM Quadband:850/900/1800/1900MHz
UMTS Tri-band:850/1900/2100MHz

type *#*#4636#*#* in the dialer and then go to phone info, scroll down a little bit and you'll see it .. there is no UMTS there ..
i forgot to mention that I DO GET CONNECTED to hsdpa when there is good signal , but when there is low signal it switches automatically to edge , and i always thought thats normal and its ok , but today i got really surprised , 2 iphones + 1 sgs3 , that were on the same network operator were having much faster internet than i had. i had 2 E bars , the s3 had 2 H bars. and as i said before the s3 had just about the same signal strength (dBm and asu)
thanks for the reply though

Sounds like the iphone 4s and sgs 3 are probably connecting to the 4g network.

as far as i know there is no 4g in my country yet + the s3 is the international version so it doesnt support 4g anyway (im pretty sure its the same with the iphone)

Change your preferred network to GSM auto (PRL)

Open dialer *#*#2263#*#*
Then try desired band

Let us know what the results are for you after you change the preferred type to what i suggested in my previous post.

it won't stick.. but anyway, i guess this is the opposite of what i want (i want H preferred over E) , or am i mistaken ?

my network provider supports hsdpa on 850 and 2100mhz and edge on 1800mhz, i still want the 1800mhz where there is no 850/2100mhz signal , but i want it to be 3rd priority (where 850 and 2100 are the first 2 priorities)
theoretically WCDMA preferred should do what i want , but its not. thats whats driving nuts..
thanks for the replies

oh man.. i said it myself , my network provider supports 850mhz .. i'm using i9000 modem , which doesn't support 850mhz hsdpa .. this could be it .. is there any way to check on which band i'm connected right now ?
EDIT: the answer is *#*#0011#*#* .. i'll check this out later when the scenario happens again, and i'll post results (i'm home now and i have full hsdpa signal here, so i cant investigate any further atm)

[Q] i9305N LTE not working

Hi there! I'm sorry if there already is such a thread but I couldn't find anything quite like this.
I bought this i9305N second hand and it had the famous IMEI problem 00/02. I went to a service center and there they were able to restore the IMEI of the device. And the phone was able to connect to the 3G as normal but not the 4G network. I've never seen the 4G working on this phone and have no idea what to try. What I tried was:
different modem firmwares.
flashed CM 10.1 and again tried those modems.
tried to set the phone to lte only via the *#197328640# code.
I think that in Sweden this phone is supposed to work on only the tele2 and telenor 4g network. I've tried sim cards from both operators.
Has anyone experienced something like this? Does anyone have an idea what is happening and what I can try?
Thanks in advance.

Does yr provider support 4G?yr sim card support 4G? If all above Yes then yr area doesn't support 4G or the coverage of 4G very poor till none.

my operator supports 4G. There is 4G coverage and I've tried cards from every carrier here on contract and prepaid.

Try a phone wipe and install the stock firmware for your network .

Just out of curiosity, have you tried cards confirmed to be on 4G-enabled contracts? I had to call Tele2 and ask them to change my contract over to a 4G one before I would receive 4G speeds. Another silly thing you could check is if the phone is actually connecting to the 4G APN, for Tele2 this would be 4g.tele2.se.

Hi! This is the thing! I havent found a card with confirmed 4G on it. I was told that sim cards on contract have 4G enabled on them. I was wondering if there is some sort of a tool to scan networks around and see information about them like what freq and speed etc... I am using my comviq card now in the phone with the apn that you mentioned and that was set automatically as the phone is with the tele2 firmware. The most brutal thing was when I went to the tele2 office and asked for a 4g activated sim to try on my phone and they said that they don't have any!!!! I went to the telenor shop and when I asked for a demo sim card with 4G so that I can test my phone and he gave me a 3G prepaid card. After 10 minutes of changing settings and stuff on my phone I asked him if that card has 4G on it at all he said - no, its just a 3G. I am going a bit of topic but my point is that it is extremely hard for me to find out where the problem is.

My point is how are you planning to use 4G on the phone if you do not have a 4G contract? I mean, why all the fuss if you cannot use it anyway?

I want to be sure that the phone works on 4G after the reparation before getting a 4G contract.

Find someone with a 4G contract and ask to test his SIM in your phone.

I had a friend enable lte on his contract and then tried the sim on my phone. LTE didn't kick in. I don't know what it could be. Any suggestions please?

Hi.
I live in the "kära grannlandet" Finland and i had to call my operator to put my i9305 as my active phone.
(They change the ownership of the phone on their computer)
I bought my phone 2hand but it was factory sealed new. operator locked to the same operator that i use.
The phone was "active" to somebody else without 4G so thats why it didnt work for me.
Hope this helped at all..
Lycka till!

My friend had similar issues with his S2, I went into the phone options menu using the #xx# number and the phone itself was not set to lte mode. I am sure you can find the menu codes somewhere on the forums as I don't have them memorized. It is worth checking if you have not done so.

4g issues on Optus network

This is an ongoing gripe of mine. I'm wondering if it's just me or if other people have this problem. When I'm on 4g it intermittently turns off data for a few seconds. The 4g icon goes away and comes back a few seconds later interrupting my connection. Only happens on 4g. If I set the mobile network to just 2g or 3g I don't have this problem. I've tried lots of different modems. So I'm wondering if it's an Optus thing or an issue with my phone? ?

probably poor coverage of 4G network
Why 4G when 3G is enough for watching video etc etc?
And it drain more battery also

I'm literally right next to a big city. Its not a coverage thing. If I have a 4g phone why not use it. I get about 24 hours of battery life from it so that's not an issue

Tmobile signal boost?

So im on tmobile for a week now and my signal runs from 1-2 bars (3 if im lucky for some reason) and im on LTE right now but somtimes im on G, E and H even if im outside. I checked Tmobiles coverage on their website and i saw that im in a place where the signal should be "Excellent".
Is there i need to configure on my z1 to get that "excellent" signal or its on them?
I live in Reno NV if u want to see the coverage

I've been reading threads on several devices about Tmobile's speed and signal strength all day because I want to switch to Tmobile but don't know which device to use.but from what I can tell there are 2 different APN settings you can use and several different settings you have to enable/disable to get the right combination to get the optimal speeds and signal strength. But, one of the more puzzling things is that the type of SIM card you use also makes a difference....such as, if it was cut down from a regular SIM (weak) or if its a "prepay unlimited" SIM or just "unlimited" (the latter is better). Thats all I can deduce so far so you may want to look on xda at other devices and how they perform on Tmobile..

Sometimes T-Mobile has some network problems. I remember weeks ago that the whole network in my city crashed. You should try to call their support first and ask them if they currently have problems with their network.

[Q] No LTE on t-mobile Note 4 with AT&T service

I'm using an unlocked note 4 on AT&T(phone was to t mobile when I got it) I can't seem to get LTE does anyone know why or how to get LTE to work? 4G speeds are really slow too.

Are you using service through AT&T or using a AT&T sim through Straight talk or some other subsidiary? I would also look into the apn settings and make sure it is setup properly.

Did you download and use the LTE Discovery App? It needs to reset your modem. Also double check to make sure you entered the apn exactly the same. No phantom spaces, etc. There should be no spaces in the "apn type".
If you still aren't getting data I have one more apn you can try.

I'm gnna put screenshots, are you able to get lte ?

I have no problem getting LTE on my Note 4 using AT&T'S network.
Screen shots below. I gets decent speeds, not the crazy 40 mbs like some people get, but that is mainly because of the area I live in.
If I am closer to the city I get 35 to 50 mbs down load and 10 to 15 upload.

I am using a T-Mobile Note 4 on ATT network and have no issues. First of all make sure LTE is enabled on your number/simcard. If not call the customer care and ask them to enable LTE on your line. They will ask your device IMEI number and then enable it. If not u will only get a 4G signal on your phone
If you are having trouble getting data on your device, then use these APN settings

I have tried that one already :/
The service rep said this "You are getting LTE on your other lines. Because the device that being use on the line is sync on your account. Since the device that is sync on the line that ends with 1521 is the iPhone 6 Plus. The Note 4 does not receive data service. Because it is registered on the iPhone 6 plus." how legit is that?

If u have a phone on contract on that line, then I use guess it is difficult. Or you can go to an ATT store and say that u lost your sim card. Ask for a new one and say that it is for an Android LTE smartphone.

According to this thread, you also have to go to settings, more networks, mobile networks, network mode and change to LTE/WCDMA/GSM.
I just bought a T-Mobile Note 4 to use on AT&T, but I am waiting for an unlock code. I really hope I don't have any issue.

I know people are successfully getting LTE on T-mobile Note 4 on AT&T service, though I am not sure which APN settings they're using. Looks like there are at least 3 in this thread to try... but it may be a block from AT&T ? I can't imagine that's the case, but I honestly don't know exactly how much control they (AT&T) have over what bands a given sim card can receive if its not matched to the imei on file in their system? I guess a lot?
OFF TOPIC: How much did you guys pay for the unlock codes? (curious)

LTE works great on this phone with AT&T service. Been using it without issue for months.
I don't know why this person is having issues. Only thing I can think is that the Sim card is bad.
Paid $30 for the unlock.
My AT&T account doesn't even show a smart phone. See the screen shot below. As long as it says LTE device then it's not AT&T causes the problem.

I don't know why I'm having issues honestly. I'm trying everything that's thrown at me , I even got a new Sim card yet no LTE. I don't even care if it shows LTE indicator , but it's that my speeds are so slow. 2-5mbps download while on my iPhone 6plus I would get 50mbps download.
