[Q] Data Connection Troubleshooting - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone, this is a troubleshooting request.
The problem: My Galaxy S2 data connection drops frequently after my first root
My Galaxy S2 was the first phone I rooted, and needless to say… I’ve learned a lot. After about 2 months of using a rooted kernel and a ROM from XDA developers, I’ve had a consistent problem I can’t solve on my own. I’ve gone through about 5-6 different ROM’s and probably 15-20 modems and the problem is always the same: my data connection dies frequently because I cannot use the proper APN settings. The connection indicator will simply disappear and in Settings > About Phone > Status, the service state will show “out of service”. It lasts about 30 seconds before I assume the connection resets and it comes back.
Why I think it happens: When I was researching prior to rooting, nothing anywhere ever mentioned APN’s. I assume the settings are pretty much automatic for most carriers? I don't think that’s the case for my carrier: DOCOMO PACIFIC. After rooting, I was able to make phone calls and text but my data didn’t work at all for days. I copied APN settings from 3 different friends with S2’s with no success. I even took it to a DOCOMO tech and had him check the APN settings and verified them as correct. Out of sheer frustration, I started leaving out random items in the APN settings and it began working (albeit poorly).
I am able to get a connection if I just put in “gcpos” as the APN and nothing else, but the connection drops frequently. These are the settings that I use:
Name: Docomo Pacific
APN: gcpos
MCC: 310 (automatic)
MNC: 470 (automatic)
The settings that I’m SUPPOSED to be using are:
Name: Docomo Pacific
APN: gcpos
Proxy: 209.4.229.82
Port: 9201
MMSC: ht tp://mmsc.guamcell.csky.us:6672/ (Had to break up prefix due to posting restrictions)
MMS Proxy: 209.4.229.82
MMS Port: 9201
MCC: 310
MNC: 470
APN Type: internet + mms
The problem is as soon as I put those settings in, data will not work at all. I can make phone calls and text, but anything internet won’t work. So what gives? Does anyone know why it does this?
I botched my ROM backup, so I cannot revert to the previous ROM/modem and obviously no tech will probably touch it because my warranty is void. Even using stock ROMs and stock modem still gives me the same problems. It’s usable in its current state, but the problem irritates me to no end. Any help would be greatly appreciated. Thanks for reading!

Silly question but have you asked your phone service provider to send the settings? Unless smartphones are radically different to non-smartphones they should support receiving Service Settings via SMS Text Message from your provider.

Hi, thanks for the suggestion. I did call them up and all they did was read back the settings I already had. I found a website that lists their alternate APN settings too, but still no dice...
I'm absolutely certain I'm using the correct APN settings because I've gotten the same settings from about 5 different sources and put them in about 30 times. The problem seems to be that the correct settings simply will not work.

MMS issues on ICS and JB

Heya guys,
I've been going through quite a few different roms, trying to get MMS functioning properly, however without much luck.
Currently my best "workaround" is to be close to a wifi and have wifi enabled and send, or the other option to disable the data APN and make the mms APN default.
My Carrier requires me to use 2 APN's in order to get MMS and data working.
Has anyone found a solution for getting around this ?
My apn settings:
Data:
Code:
Name: Internet
APN: internet
MCC: 238
MNC: 02
APN type: default,internet
MMS:
Code:
Name: MMS
APN: telenor
MMSC: http_:_/_/_mms.telenor.dk (i have under 10 posts so cant post links, i have added "_"'s to go around this.)
MMS proxy: 212.88.64.8
MMS port: 8080
MCC: 238
MNC: 02
APN type: mms
i am required to be on the telenor APN in order to connect to the MMS proxy, i have tried being on the internet apn, however i get connection refused.
Well i guess i should state what i am currently using.
I am currently using mimicry 1.5.0 on a HTC desire Z works great except for the obvious M.MS problem.
I have a thread in the desire z forum, however since i beleive this issue is not just related to my actual phone, i thought a broader audiance could help with this.
bumping the thread, i guess i posted this thread a bit outside the useual active times, got completely burried.
Latest update, MIUI has this problem fixed in their ICS build, however their build is a bit too unstable on my phone (reboots all the time)
maybe if someone knows an app or maybe even a script etc that can ie change APN settings apon mms receive and send, and change it back after its sent/downloaded, i could live with such a workaround without complaining.
I have also written to my carrier in hopes of they can provide me with a single APN setting for both data and mms (i think they already have one, but since my rom does not have support for auto config of apn's apon msg recieve from carrier i am unable to enable it.)
If someone knows of a tool that can help handle this, i am willing to give it a try.
My phone is of cource rooted, would not have it any other way
bumping again, nobody with a suggestion ?
Another bump, in the hope of someone knowing a solution.
bump again, still no luck on this end.

[Q] Unlocked Galaxy Note (i717) on ST T-Mobile Text (SMS) not working to Verizon

I've done some searching and didn't happen to run across anyone that was having a similar problem. Originally, I thought this might be a StraightTalk/Verizon issue, but I've confirmed that one of my family members with ST T-Mobile can text with Verizon folks just fine. So let me dive into the details...
I've had my StraightTalk T-Mobile sim card for about a week now. I activated it without any problems, set up the APN and everything seemed to be working just fine. I've been texting with a few family members and some co-workers without issues. My data and voice calls are all working fine as well.
I went to text a friend that has Verizon post paid service and he never got my text. So I sent a few more without success, then tried to text my own Verizon number (since my account is still active for the moment) and I never received my own text either. He sent me a text message that I received just fine though, but again he didn't get my response. Just to further test, I send an MMS message to myself and my friend on Verizon and that came through just fine, so it appears that all texting capabilities work with the following carriers (AT&T, Sprint, Verizon, ST T-Mobile) with the exception of regular SMS to Verizon.
Here are my APN settings:
Name: StraightTalk T-Mobile
APN: wap.tracfone
Proxy: Not set
Port: 8080
Username: Not set
Password: Not set
Server: Not set
MMSC: http:**mms.tracfone.com (replace ** with //, since I can't post links)
MMS Proxy: Not set
MMS Port: Not set
MCC: 310
MNC: 260
Authentication Type: Not set
APN Type: default,supl,mms
APN Protocol: IPv4
Bearer: Unspecified
About the phone... I purchased an AT&T Note (sgh-i717) and unlocked it myself. The unlock was successful but I was only getting edge data since T-Mobile has re-farmed the towers in my area yet. So, I installed CWM and flashed the Blaze4G radios. I'm now getting consistent signal and H+ speed (4-8 mbps avg, 14 mbps peak). The only other thing I had to change was that my phone number wasn't showing up in the About Phone -> Status section, so I went into the dialer -> Settings -> Additional Settings -> My Phone Number and set it there in the format of xxx-xxx-xxxx. I also just flashed the T-Mobile VKL1 radio as well but no change in my sms issue.
I'm a bit lost at this point on why everything else would work except for sending sms to Verizon but yet I can receive them from Verizon just fine. Any suggestions would be greatly appreciated.
Texts aren't immediate when the network is busy. Sometimes the delay can be several hours.
None of my Verizon messages are ever delivered, some from 3-4 days ago. I called Straight Talk tech support and they are tracing some of my messages. One of the things they thing might be wrong is the message center number that is configured in my phone but they didn't want to change it until after they could do further research.
Update: Confirmed the smsc is correct, so that doesn't appear to be the issue.
Just a follow up in case anyone else ever had an issue similar... a T-Mobile technician called me today, they found out Verizon had blocked my cell phone number from their network. After the tech got the ban lifted, texting is working just fine.

That's interesting. And it sucks. You could have spent hours\days working on something you could never fix. Did they give any reason for your block? Glad you got it worked out.

You'll want to flash the T-Mobile ROM in the development section. Follow the instructions carefully.

T mobile USA - Connecting Problem

I have tmobile when inserted the simcard in my z2 I've noticed that I'm not getting any internet connection so i went to Setting/wireless and networks/internet setting and downloaded all the files then I went to mobile netword and changed it to 4G Tmobile, starting that day I keep losing connection every time I have to go to mobile network and change it manually although it's set on automatic, most of teh times 4g doesn't work and I have to set it to 3g... it's really annoying
In your dial pad type in *#*#info#*#* (numbers for info)
Go to phone info
Scroll down
Select prefered network mode
Select LTE or an option for local with
Go back to your network settings and see if 4G shows up
If not change your mode back to what it was before and call tmobile because they may have to sort some issues out for you

go to your network settings, when tmobile USA shows up with 4G click it to register, once thats done, go back a menu and click on network mode and change it to LTE/HSPDA/GSM (or what ever bands are used in USA)
you should have data connection but 4G depends on how good Tmobile USA Coverage is
You may need to call TMo and ask them to do whatever they do in the backend to reset the phone to network connection. Another thing is to look at TMo support site for the correct APN settings. In my case, data was perfect but MMS would not work because the phone settings were incorrect. Basically, call TMo. They will even email you the settings.
One last thing. Try airplane mode off then on and see it that helps.

One thing I would do, is to call T-Mobile and register the IMEI so they can provision the unit. The settings on their end may have something which is preventing it to connect to it based on a previous phone's capabilities.
-----------------
I had something similar similar but it was with AT&T. In my case, it would not connect to LTE at all as it would stick on HPSA. This was because I had a S3 (UK version), which was only capable of HSPA+, and I had registered the IMEI with them prior.
I had a lot of problems getting my Z2 to work on T-Mobile as well. I finally used the following settings to get everything to work.
Create 2 APNs, the first should have the Following Settings:
Name: T-Mobile
APN: fast.t-mobile.com
Proxy: 216.155.165.050
Port: 8080
MMSC: http://mms.msg.eng.t-mobile.com/mms/
MMS proxy: 216.155.165.50
MMS port: 8080
MCC: 310
MNC: 260
APN Type: defaul,supl,admin,dun,mms
APN Protocol: IPv4
APN Roaming Protocol: IPv4
Now create a second APN with the following settings:
Name: T-Mobile GPRS
APN: epc.tmobile.com
MCC: 310
MNC: 260
APN Protocol: IPv4
APN Roaming Protocol: IPv4
With both of those created, go to your list of APNs and make sure your first one (T-Mobile) is selected.
These settings fixed my problems, hope you get it worked out.

I had a similar issue, is that why my phone doesn't have signal with tmobile cause I have to register the IMEI?

It is likely, make sure the internet/mms settings are downloaded too.
Once the IMEI is registered, they will able to see what phone it is and enable the proper features which the phone is capable of.
I heard it's best to let them know as the IMEI as well because they could flag the unauthorized phones and reject it from being connected the carrier.

[Q] MMS/APN Issues with CyanogenMod 11

So ever since I did a wipe and flash last week of the CyanogenMod 11 nightly, I haven't been able to send/receive MMS messages. If someone sends me something, I'll get a message saying that they sent me something but it cannot be downloaded. From what I could tell, it could be my APN settings. I've tried a bunch of different things, the main two being what's shown on this webpage, and the following (default) settings:
Name: Verizon Internet
APN: VZWINTERNET
MCC: 311
MNC: 480
APN Type: default,dun,supl
APN protocol:: IPv4/IPv6
APN roaming protocol:: IPv4/IPv6
Now sometimes MMS will work, but take FOREVER to download. Other times, it just doesn't download. This is becoming really frustrating since I use group messages a lot to keep in touch with distant friends.
Could someone be able to help me out and tell me what I'm missing? This is becoming a huge inconvenience. Any help would be much appreciated!

Verizon Galaxy S5 on Straight talk, cant get MMS texts to work.

I just switched my verizon phone to straight talk. Im finding out one of the things thats saving me money is terrible customer support...
So I have an S5 SM-G900V running 4.4.2 unlocked.
So I switch to straight talk and everything is great. Same exact service as verizon for half the price. The next day I get a text that my data plan has been updated from 5 gb to 8 gb. They told me this would happen. Now when they switch my plan over they also reflashed my APN and broke my data/MMS. Get on the web google a little bit download a couple things and within an hour Ive got the APN properly working and data going just fine. Next day I try to send someone a picture via text and realize I cant receive or send MMS'. Get back on google tonight to configure the texting an APN settings and for the life of me I cant get it to work. Ive tried numerous old and new MMSC's proxies, ports, etc. I managed to get my downloading working but uploading refuses to play nice.
My APN reads as follows right now.
APN: TRACFONE.VZWENTP
MMSC: HTTP://MMS.VTEXT.COM/SERVLETS/MMS
MCC: 311
MNC: 480
APN TYPE: DEFAULT,DUN,STDHIPRI,SUPL
APN PROTOCOL: IPV4/IPV6
APN ROAMING PROTOCOL: IPV4/IPV6
BEARER: LTE
If I didnt listed the field is blank. So as a small note my wife has the same exact phone but with the next version of android and is having no issues. Her APN reads exactly the same except the MMSC is set to default, and the APN TYPE doesnt have STDHIPRI. I tried her settings not luck. Also the MMSC im currently on is not what worked for downloading so Im broken on up and download right now. I used an older tracfine address that got downloading working. This vtext address is what is listed as correct for a verizon phone everywhere on the web...
Also Id like to add I wanted to try some settings I found with different MCC and MNC numbers but if I change them it immediately deletes my APN profile...
I did also try go sms and some other recommended messaging apps and it made no difference.
Help please lol. Im getting super frustrated.
Well I just fixed it. Go figure I walk away from it for a couple hours, make a post, screw with it for 10 minutes and figure it out...
SO for anyone else on the internet with this issue here is the functioning current APN for a verizon phone on straight talk as of 8/2017
APN: TRACFONE.VZWENTP
MMSC: HTTP://MMS.VTEXT.COM/SERVLETS/MMS
MCC: 311
MNC: 480
APN TYPE: DEFAULT,MMS,SUPL
APN PROTOCOL: IPV4/IPV6
APN ROAMING PROTOCOL: IPV4/IPV6
BEARER: LTE
It was all in the stupid APN Type line. Apparently either my phones a screw ball OR perhaps newer android phones default better on certain settings that my rooted phone cant? Either way this stupid line changed worked to fix both my downloading and uploading...
