[Q] Seems like my 3G isn't working

I bought this phone brand new, everything was wrapped in its cellophane. I asked the seller if this was in fact a 3G phone to use in Europe because I needed the UMTS 2100. The box itself writes " HSPA/WCDMA 900/2100 " Greece runs on UMTS 2100....When I try to use the internet search engine it says "There is no Network connection right now". I check my Mobile Network settings and Data Roaming is checkmarked. Network mode has GSM/WCDMA set to auto. Network Operators states Greece Cosmote.
What haven't I checked to make the connection?
I do believe this is Euro/Asia version because it has like 7 different English languages for Asia (Singapore/Malaysia/Vietnam etc...) When I changed the Bluetooth name, the default was HTC Vision (which is the UK name of this product)

Check in settings/wireless&networks/mobile networks/ and make sure that "Use only 2g networks" is not checked.

I don't have that option.
In the Mobile Network Settings screen I have
Data Roaming (Checked)
Data Roaming Sound (checked)
Access Point Names
Network Mode (GSM / WCDMA (Auto)
Network Operators (GR Cosmote)
Enable Always-on Mobile Data (checked)

Have you tried to select WCDMA(3g) mode only to ses if that works or helps, I notice its on auto.

Are you saying that you only have a 2G/EDGE connection or that you have no data connection at all? From the thread title, I thought the former, but from what you are describing, it sounds like the latter. If it is the case that you have no data connection whatsoever, check to make sure your APN settings are correct for your network provider.

Where do I go to check the APN setting....I found an APN screen but it is completely blank....How can I add parameters to that screen?

No APN = No Data, I would try googling the Greece Cosmote APN data settings first.
UPDATE: I tried to google the APN settings for you but "ITS ALL GREEK TO ME".....lol J/K, but not.

Okay....I am getting the hang of the Android OS now...sorry...I am a migrant from Win 6.5...
I got the info from a website for the service provider....it seems it wants an IP address to be inputted where it says DNS...the problem is I don't see a place that says DNS....does that go under the "Server" area?

Try here maybe:
http://www.prosoxi.com/2010/02/17/greek-apn-settings-cosmote-vodafone-wind/
EDIT: woops think this is what you just said no DNS right, What about "proxy" do you have that? Try it in the proxy field.
Sent from my HTC Vision using XDA App

Got it so far....for the proxy there are two listed....."Proxy" and "MMS Proxy" which one does the IP address go under?

Are you asking if you should put DNS under the proxy or mms proxy fields? No, these are different things. Have you tried inputting all of the other settings except for DNS and seeing if it worked? Most carriers will work without you setting the DNS (it's pulled in by your phone dynamically).
In most cases, you need to put nothing more than the APN (and username/password if required). For MMS to work, you'll also need to find your carrier's MMSC, MMS proxy, and MMS port.

it seems like I finally got it to work. I had to switch a few parameters around...Had to call the phone company. I love this phone. I wanted the physical keyboard but the on screen landscape keyboard is proving to be just as effective.

Sweet!
Gotta try it.

Wow, ROM flies!!!!!, feels like brand new tablet. Still testing out everything, but so far so good. Android is so awesome because of the great devs, thanks!!!

Only issues so far are MHL out doesn't work (anyway to get this working?) and the touch sensitivity seems off. Have to press hard and hold links in browser for example. Other than that, this ROM is awesome!

Can i use this rom in P7320 LTE 8.9 tab ?
What should work, and what shouldn't?

Try rebooting without a charger connected and make sure wifi is off. If that doesnt work, wipe and reinstall the ROM. If THAT doesnt work, maybe try flashing a skyrocket modem similar to the CM10 stuff.

Tried all but a skyrocket modem.
Ill give that a go.
I show bars of service, shows att, then states no internet connection.
Imei is still good, and stock or cm10 work.
Weird..

No problem. It may be helpful to post the settings here for other users who may have the same issue.
Code:
Name: Broadband
APN: Broadband
Proxy: Not Set
Port: Not Set
Username: Not Set
Password: Not Set
Server: Not Set
MMSC: Not Set
MMS Proxy: Not Set
MMS Port: Not Set
MCC: 310
MNC: 410
Authentication Type: Not Set
APN Type: Not Set
APN Protocol: IPv4
Bearer: Unspecified

Default APN settings are determined by system/etc/apns-conf.xml. The specific ones used are determined by the SIM's MCC/MNC settings, in the case of an ATT SIM, 310/410.
The default file has 310/410 set up like:
Code:
<apn carrier="ATT" mcc="310" mnc="410" apn="wap.cingular" user="[email protected]" mmsc="http://mmsc.cingular.com" mmsproxy="wireless.cingular.com" mmsport="80" type="default,supl,mms" />
<apn carrier="ATT LTE" mcc="310" mnc="410" apn="pta" mmsc="http://mmsc.mobile.att.net" mmsproxy="proxy.mobile.att.net" mmsport="80" type="default,supl,mms" />
<apn carrier="StraightTalk ATT" mcc="310" mnc="410" apn="att.mvno" mmsc="http://mmsc.cingular.com" mmsproxy="66.209.11.33" mmsport="80" type="default,supl,mms" />
The first and last line there can be nuked, and the ATT LTE line like:
Code:
<apn carrier="ATT LTE" mcc="310" mnc="410" apn="Broadband" mmsc="" mmsproxy="" mmsport="" type="" />
That'd result in working connectivity for users with a data-only LTE plan from ATT, as usually sold with these devices.
The quirk I'm trying to figure out, though, is how to get LTE. The RIL seems to default to WCDMA preferred (3G), but AOKP's settings don't seem to provide the selector to select the "other" setting, LTE / WCDMA, which enables LTE.
Probably just a toggle to flip in framework-res or some other similar config setting area... finding it is the fun part!

Can anyone confirm/deny if the touch screen seems wonky?

No LTE with Credo and Cyanogenmod 10.2

Hello XDA,
I love Cyanogenmod, it's so much better than TouchWiz! My only issue is that on my Sprint Galaxy S3, on the Credo Mobile network (an MVNO of Sprint), I don't get LTE...I know I have fair LTE signal in my area because on TouchWiz, I get LTE. On Cyanogenmod, however, I get 3G, and when I turn on the LTE toggle, it either stays on 3G, switches to 1X data, or loses data connection altogether. I've done PRL and Profile updates, and the problem remains.
Any help would be greatly appreciated!
Thanks!

I'm also on Credo. I moved over from AT&T, which is a company I never cared to do business with and which also always seemed to treat my business as an annoyance, but which had great coverage. I put our whole family on Credo because my wife was a longstanding customer. I haven't had decent coverage at any time.

Credo runs with Sprint, so i wouldn't expect decent coverage. I know that I do have LTE coverage in this area, but I can't use Touchwiz because my SIM somehow got PUK blocked and Credo refuses to give me the PUK code because I'm rooted. So yeah.

While it's true that Sprint's coverage isn't great, the OP said he got coverage before installing CM. So it's likely that weak coverage is not the issue.
Also, I'm having the same problem. :/

More info...
It's not rooting itself that is the problem. I simply went back to the Nandroid backup I'd made before loading Cyanogen, and internet connectivity returned while I was still rooted.
I had the same issue with Liquid Smooth that I had with Cyanogen, and got out of it the same way.
And I've seen posts where people said that "Your signal isn't really any different - it's just that Sprint and other carriers pad their signal strength meters to make themselves look better, and loading a new ROM omits that," but that can't be the core issue either, because with CyanogenMod and Liquid Smooth, I was unable to connect to sites/apps with a "check your internet connection" error, whereas I could connect to them in the same place once I returned to my rooted/stock ROM status.

I'm a Credo member in Minneapolis experiencing the same issue with my GS3. What I figured out by accident is that I can get an LTE connection by making a backup of my phone, then wiping it, restoring the backup, and wiping my cache and dalvik. Two times in three I get LTE when the device reboots, but only until I restart the device or switch to a wifi connection and back. I've been experimenting with different radio/baseband versions (as described here http://forum.xda-developers.com/showthread.php?t=1787677), but so far have had no luck getting LTE to stick. Hopefully this will be resolved with further development, but fortunately my 3G speeds are pretty decent, so I can wait for a long-term fix to (hopefully) fall into place.

I've figured out what my issue is, I'm not sure that it will apply to you. Somehow, the internal LTE SIM card got PUK locked, which is why i can't get LTE on cyanogenmod, or use touchwiz at all...and Credo doesn't even have access to the PUK codes! I'm wondering if I can use this to leverage my way out of my contract without paying ETFs...

No, APNs are not the issue. I can't even use the phone AT ALL in Touchwiz...when I boot in to touchwiz, even unrooted, it asks for a PUK code, which I don't have and can't get.

Dumb question: the cursory bit of reading I did on PUK codes after seeing this post suggested they applied only to GSM phones, where I understand Sprint/Credo to use a CDMA network. How is the issue applicable even in your case, and where would you go in CM to enter the code if you did have it?

It is true that Sprint is a CDMA network and does not need a SIM card to function for basic voice and 1X or 3G data, but 4G LTE requires a SIM card on both GSM and CDMA, most CDMA LTE phones have that SIM card embedded. In Cyanogenmod if you go into Settings -> Security -> SIM Card Lock. That's how I accidentally locked myself up.

Anyone figure out how to get 4g or LTE to work with the samsung galaxy s3 on credo with cyanogenmod 10.2? I was reading that 10.2 fixed the issue, but I still get no connection when I try it out. I also can't send mms on my phone, so i'm thinking of flashing back to stock, fixing the APNs, and then hopefully re-flashing cyanogenmod. Wonder if that'll fix it.

I'm going to just flash with the stock ROM, update the prl, profile and everything to the newest versions, and then backup that rom again, then install cyanogenmod again.
I'll let you know how the process works.

It worked with Credomobile in the Atlanta area using Sprint LTE. See instruction below

Ho. Ly. Crap. That finally did it!
From the APNs menu (I accessed it with a shortcut in Nova Launcher, but I believe you can say "open APNs" in the dialer to do it?) I selected Sprint Internet and edited the name to n.w1.ispsn. After that, I toggled airplane mode and my phone was finally able to connect to an LTE signal! Huzzah!
Thanks for everyone that helped out in this thread. Hopefully this'll be helpful to others in the future.
And now I am off to get my shiny new CM ROM set up

Damn, quoted the wrong post. I was referring to hanson's post about renaming the APNs.

Latest Credo Mobile APNs
Ok, Cyanogenmod doesn't come with the correct APNs for 3rd party Sprint Network users. You have to remove the default APNs and then add the latest Preferred Roaming List. Also known as the Access Point Name (APN).
Here is the file with the new Credo Mobile APNs for any ROM that can't connect to LTE or to Sprint's servers to get MMS messages.
https://www.dropbox.com/s/7es3vh5c67jdqwh/apns-credo.xml
This xml file is structured to be used with the app "APN Backup & Restore" .
Make sure the APN app is moved to the system folder. I used "/system/app mover" to do this.
Below is the code to the XML file.
Code:
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<apns count="4">
<apn name="APN0 LTE ota" numeric="310000" mcc="310" mnc="000" apn="otasn" user="" server="" password="" proxy="" port="" mmsproxy="" mmsport="" mmsprotocol="null" mmsc="" type="fota" />

UPDATE: This list of APNs provide 3G, 4G LTE EVDO, and 2G CDMA but NOT MMS support. I don't know why. I am looking into updating my code.

2015 cm 12.1 credo mobile APN settings
since this is the first XDA thread showing in my search results, I'll just bump this for posterity. CM has implemented the Credo APN settings into the frontend settings app since at least CM12 (poorly, but they try. I'm sure the carriers don't make this a simple task with ongoing network config changes. )
I had to switch my network mode to LTE-only in order to get my APN settings to actually list the props available. Once they were shown, I finally figured out that I could just edit the Sprint-LTE-internet profile and just edit the correct gateway (n.w1.ispsn instead of just n.ispsn)
Here's some screenies for the entire prop settings that got me connected to LTE after an airplane-mode toggle:

If the profiles list doesn't populate, try using different " preferred network types" but lte-only worked for me.
On other aosp roms you might have to open voice dialer and say "APN" to get into the cdma settings/ hidden menu

[Q] Change 3G band to European GSM 900/1800

A family member gifted me a Galaxy S4, however it is the SGH-M919. I currently live in Europe and 3G bands in my region are GSM 900/1800. At the moment I can't access 3G and any other type of data for that matter (LTE is not supported here). Is there a way to change T-mobile 950 and 1900 bands to my region ones?
Thanks for taking your time to answer

Sadly not.
Since the radio does not support those frequencies for hsdpa

So there's no way to fix it?

Hello Flex,
I have the same phone "Samsung S4 SGH-M919 - Tmobile" and I live in Hungary, it works fine with me all you have to do is just to switch form WCDMA/GSM to any other option "like GSM only" then back to WCDMA/GSM as a kind of refresh and the 3G will work fine after that, you can find this inside Settings > More Networks > Mobile Networks > Network mode, but unfortunately you have to do this every time you restart your device.
There is also another alternative solution is to reset the Access point names to default, you can find this inside Settings > More Networks > Mobile Networks > Access Point Names.
to be honest I don't know the reason of this error, but try what I described and tell me if it works with you.
Good Luck

Well. I have the exact same phone and have tried several ROMs, either custom or stock and basebands also. Nothing seems to work. The very few users who reported it was working didn't provide much evidence of it. Even Wikipedia says no 3G 900MHz availability for this phone. A simple edit to NV 1877 values won't solve it. I've tried that too.
