Noo,why does need this? If my provider does not suport my dwvice there is asolution?

I have been having problems with my mms since I first received my Nexus. MMS take 3 days to send and downloading mms gets stuck at downloading and never opens. I did some research and from what I understand it has something to do with your APN settings, try searching for the correct APN settings for your area and provider. APN settings can be found in ---> SETTINGS>WIRELESS&NETWORKS>MOBILE NETWORKS>
ACCESS POINT NAMES
** I have yet to fix my MMS issues, if you find something I would love to know

Yea, I don't know if re-flashing the ROM would be of any use. Some people argue that MMS only work if you have a data plan with your provider, but I've read otherwise as well. I've also heard of Nexus users getting more up-to-date sim cards and that fixed their issues, maybe worth a try? You might want to give your provider a call and ask them for the correct APN settings or at least explain your problem to them and see if they offer any assistance.

No mobile data CM7 G2x using Cincinnati Bell

Is anyone making any progress on this issue? Any OTA based ROMs work perfectly. Any ROMs based on CM7 refuse to activate mobile data.
They also are unable to read the mobile number or the VM service center number from the SIM card. I think the two are related.

Did you set your apn and enable it? I'm sure you did but need to ask.
Yes, the APN is set (green dot) and mobile data is enabled. I've tried setting and then unsetting airplane mode to try to get mobile data going.
I've also tried getril to make sure the ril and baseband match. I've also dropped Stk.apk from the OTA rom into /system/app on CM7 to no effect.
This is both in the release version and 174 nightly.
I'm on T-Mobile and data works, but it's definitely not as stable as the factory based roms. I always thought it had something to do with not being able to read the sim card information too.
Data on CBW
Hi,
I had a similar problem. You have to both put in the correct APNs (search online - CBW support center gives out most of the values)
But you also need to go into *#*#4636#*#* (4635 spells 'info'). Select the phone information button and scroll down to "SMSC". You'll have to search online to see what the correct value is (it doesn't display it otherwise I would just read it off for you). Search for a website that gives it in hex values. Input that hex value and restart your phone. That should fix both data and SMS if I am not mistaken.
Hope that helps
Okay so here's the SMSC from my working ROM:
002B00310035003100330032003400300030003100340030
Going to give it a shot.

Putting in the SMSC didn't seem to make a difference. I'm going to experiment more tonight.

I've been trying to input my smsc as well. In with wind but I find it weird that both me and you have the same smsc number. So I think that nag be partially our issue.

I pulled that SMSC number from the OTA T-Mobile ROM. With working data and SMS on cinbell. I have a feeling that it doesn't mean what we think it means.

I run stock GB 2.3.3. rooted and I get data on all carriers in Thailand. I get 3/4G with TOT3G and Edge with AIS, DTAC and True.
You should have no problem getting data by simply entering the correct apn. Also on Cincinnati Bell bell you should be getting 3G+ data.
Maybe I didn't say it clearly enough. I get working data including 4g on any ROM based on the 2.3.3 OTA. Weapon, rooted OTA, debloated, etc. I only fail to get data on ROMs based on CM7.
And yes, the APN information is right. I've even tried making a new APN entry with the settings that work on OTA ROMs.
It's like the radio isn't working right in CM7.

Maybe try a different ril. You can use getril app

well i am new to this and i have the same issue, i first tried to install cm7 172 and had no signal what so ever but i could connect to wifi, so then i started over and used cm7 182 and still no signal, soo, then i reflashed gingerbread 2.3.4 rooted, still no signal, so then i called tmobile and asked them if everything on their side looked right and they said it did.
so i conclude that it is whatever we are not doing
that being said i hope some one can tell us what to do cause afterwards ill make a tutorial for those of us who go thread to thread looking for answears

I've tried that RIL matches.
I'm seriously wondering if it's the radio baseband. I've got the July 2011 tmobile version. V21E RIL matches.

I have an answer, or at least a work-around. Can't claim credit for it, read it on the Cyanogenmod forums.
In the apn settings, fill in EVERYTHING. Even PAP/CHAP. Save. Then go back and clear out the ones that should be empty. Save again. It will start working.
There must be an APN field that doesn't start null in the CM7 base, that T-Mobile uses that CinBell doesn't. That would explain why T-Mobile users never experienced this issue.
I've narrowed it down some more. Authentication type needs explicitly set to none. I'm submitting a change request to CyanogenMod.

Thank you for posting this Terry, this got data working on my newly rooted g2x on cincinnati bell with the MIUI 1.25.11 ROM. However my MMS settings must be screwed up as I'm still unable to send MMS messages. I'll keep tooling with it, but for now data is as it should be. Thanks again.

It now works.
It have to be fixed, as I'm using the latest nightly (20130301) and it's still a bug, and this is the latest available CM version for p999.

SMSC nr + data connection

hey guys,
after updating my nexus s to ICS recently, i developed an issue with the radio, not connecting to a data connection. after some research, i found a diffrent radio which might fix everything.
It didnt, it made everything worse. i cant send any sms's anymore from my nexus s, and still cant data connect. i've been researching since than, and found i should re-enter the smsc code in *#*#4636#*#*. i've searched my smsc code which appearantly was +32486000005, after converting this to PDU, i got 07912384060000F5 as final code which i should enter. after entering it in my nexus S, it gives an 'update error'. I've no idea what i should do now to fix both the data connection and the smsing.
Thanks in advance
What service provider are you using? What rom and kernel? What radio? More details makes things easier when trying to help you. I had a similar issue on my Nexus S. I'm at work now but when I get home I will flash my phone over to the same from, kernel, and radio you're running and see what's going on.

Hey atrix, thanks for the reply.
I got Mobile vikings (belguim)
Rom is currently the official ICS, but the same issue occured with GS, gingerbread CM7 and kangy's
Kernel =3.0.8-gb55e9ac
i used matrix's and SG's aswell, all failed.
radio is kli, tried with kb3, and a few others
Alrighty. Thanks for the background info. Ill load up in a bit here and get to testing. It may just be a bad combo of kernel/rom/radio.

I did a little digging myself quick while the from and stuff download. Slow internet here lol you run an mvno from Base there in Belgium. So you'll require the 850mHz band for GSM connection and wcdma 2100 band for your 3G. Now what were gonna have you do first is dial *#*#4363#*#* and let me know what it says right above radio. I'm going to start checking basebands to make sure they're 100% compatible with your MVNO.

Enable / disable radio? -> GSM/CDMA auto (PRL)
Switch to wcdma only. Also do you have voice right now and just no data/SMS/MMS? Also under settings-wireless and network-network/mobile provider-APN/access point names what do you have set up in there?

i get a screen with APN's on top, and nothing on screen
Bloody hell. That's your problem. Create a new APN there with you're MVNO/ service providers settings. Ill see if I can dig em up for ya. However I don't know if it will for sure fix the SMS part of your problem. It may but I'm not sure

Also reset your radio again to GSM/CDMA with the *#*#4363#*#* option. Test and report. Then well narrow down more problems if they exist.

One piece of advice too. BACKUP YOUR EFS PARTITION!!! Ill see if I can dig up the thread and link it for you. It contains your IMEI AND SERIAL NUMBER and all that good stuff. You ever corrupt, lose, or erase that partition and you'll never get it back. That partition is unique to each individual handset.

I have the same problem. At the moment i'm using CM9 and can't change the smsc. I tried to follow the advise given by astrixboy but got to the point where i couldn't find where to create a new APN.
Anyone who knows where to find this?

No cellular data

Ok, after asking on various Rom threads to no avail I'm making a topic about it seeing as I'm not alone on this one...
I seem to have lost all cellular data. When I turn on mobile data I keep getting ' connection failed due to incorrect apn settings'
I have flashed different roms, re flashed current viper Rom, factory reset, full wiped, reset apn to default settings, even got a new sim from my service provider. My apn settings are correct, as have been confirmed by my service provider, I've updated radio and firmware...and still no mobile data.
Does anyone have the faintest idea what's going on?
Thanks guys.

Hi,
Have you tried deleting ALL your APN settings,rebooting,then,re-installing them?
Just tried your suggestion malybru, unfortunately it hasn't made any difference
Sent from my HTC Sensation Z710e using xda premium
I'm running viper too and when I upgraded to recommended radio this happened to me. I lost all data connection ! To restore my data I used one of the five(I believe it's 5) generic ics radio and matching ril. I got lucky first one I tried worked for me! I'm not exactly sure of your situation but it sounds very similar to what happened to me... You might want to try the generic ics radio with matching ril.it restored my data right away. You will have to do some searching to find it. But it's there. This just happened to me last week. I really hope this helps you! It worked for me... Best of luck.

this problem seems similar to the problem i faced recently ..i would have complete signal ..but no data
in my case ..if i change the network mode to GSM only ..i used to get Edge
the thing which caused this problem in my case is... loose sim ..yes the sim is loose ..and i kept a paper on top of sim to make it fit tight ...and voila problem solved ...just try this ..it might work
:fingers-crossed:
also check in phone testing that you are st to WCDMA preferred
from key pad *#*#4636#*#* phone settings - look for the only drop down box - hit it choose WCMDA preffered then home
I even lock on wdcma only by pressing *#*#4636#*#* and go to phone information press your current channel and another menu will come up, choose your desired channel from there then press refresh. My device kept going to edge sand it drove me crazy so I locked on wdcma only
And had no problem ever since. I now stay on H. I'm sure it depends on your area also but I've never lost signal doing it that way.

Verizon Roaming?

dude, i just went thru the same exact thing today. i even went totally stock, kernel, recovery and everything, still stuck in roaming.
i spent hours then i did the factory reset code on the dialer ( *#7780# (Factory Reset) ) and it worked again, i was so happy because i was thinking that i have to deal with the bs with sending the phone back or getting a new sim if that was the case. i hope it works for you also.
EDIT: i thought you were stuck roaming, not that u wanted to roam hahhahaha nevermind
