Noob, need help with data issues - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So recently seemingly randomly, my rocket tries to say I have lte when I should only have 4g. I live near DC, but not close enough for lte. So when I try to send a text, it often fails and needs me to resend it. For someone who sends 25k a month, this is ridiculous. I'm not sure if the whole device is breaking or if the lte and texting issues are related. Help??

Change to gsm/hspa only in mobile networks, then it will disable the LTE radio, problem solved

When I go to mobile network settings, I don't see any options to be able to change it to either of those options. There's not much of anything that I can even change there. Is my version /build different from yours?

Yeah you aren't rooted and don't have a custom ROM

So besides rooting and flashing something that'd work there's nothing I can do to disable LTE?
I figure I'll take my phone back to the at&t service center to get a new one then, since it's only 3 months old.

All incoming calls going straight to voicemail

This started happening 3 days ago.. My gf had to call me 8 times last night before she got through to my phone.. I don't know wtf is causing this but i'm pretty sure its not the phone or ROM. Also at times incoming texts come in late.. My apn is set correctly.. Any help would be appreciated
Sent from my SAMSUNG-SGH-I727 using xda premium
When I'm blocking someone its on purpose and I use call master. If there is a problem with connectivity I can reset the radio layer or reset the telephony service. This might be an idea just to have the ability reset the radios at different levels in order to clarify the problem
Sent from my SAMSUNG-SGH-I727 using xda premium
How do I reset the radio? And I do not have anyone blocked or call forwarding enabled
Sent from my SAMSUNG-SGH-I727 using xda premium
I use a call blocking app like call master or root call blocker. It allows in the setting to reset the radios individually.

Believe it or not removing the sim sometimes works as it registers/unregisters you from the network.

Just flashed stock radio and same issue.. Tried the Sim card removal twice last night too
Sent from my SAMSUNG-SGH-I727 using xda premium
edit----if nothing else helps try reflashing. If that doesn't work get new sim(no charge if you say it is defective ) make sure your reflash stock rom.
If that doesn't work, send in for trade under one year warrenty.

Yes im in canada on rogers network (rogers is only in canada) I flashed sky coke rom, before that was on quickwiz which i had no issues with
maybe that ROM had trouble with Rogers network. I would contact the developer and seek some sort of resolution

Went back to a rogers based rom and same ****... which leads me to believe it aint the ROM or the phone.. ****
Is it prepaid? I know sometimes prepaid have issues
Sent from my SAMSUNG-SGH-I727 using xda premium
No its a monthly plan. I called up rogers tech support and he had me change the network mode to gsm only and he tried calling and it went through, then hspa and same thing with data on.. went to gsm/hspa/lte auto and with data on the call went through fine.. as soon as I got off the phone, I tried calling my number and calls stopped going.. (put it back to gsm only and it started working even with data on, but when its on LTE with data on is when it starts screwing up) does that mean when its connecting to an lte tower its messing up? Is that my phone's issue or the towers? Is there anything I can flash to the phone to see if the problem goes away.. already flashed stock radio but didnt help
Same issue here. Att user. Sky ics rom.

any fix??? it just started happening like four days ago and never had this issue before.
This is a known issue, at least in Canada with Rogers. It has nothing to do with what rom or Kernel you are using.
It appears that Rogers is having intermittent issues with the LTE network. It comes from the handoff between LTE and 4g when a voice call is received. After you hang up, you are supposed to go back to LTE automatically. But with this glitch sometimes the phone will get stuck and as a result you get no texts and calls going straight to voicemail.
You could try creating a new APN node for 3g/4g only and using that to see if it solves your problem while Rogers is actually becoming aware of the issue and fixing it.

Last night alone it took 40 minutes for a text from my wife's phone to arrive. And that was only because I turned my phone on and wifi kicked on!
Thank you for your response. So they are aware of this issue? Also, what should the settings be for a new APN?

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.

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

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?

Unable to get 4g back after using Phone App.

I selected the (CDMA auto PRL) for 3g only then didn't like it so i wanted to switch back but it would not let me. so now i'm stuck on 3g selected (CDMA auto PRL) every time I try to switch the setting to something else it just reverts back. Did anyone else have this issue? Please is their a fix? I need help to get the 4g back on my phone. (Galaxy S3 Verizon, rooted)
I had to reset the phone and install a different rom to make mine work. Hopefully that helps.

Hope you get your 4G back and try a hard reset to fix it.

The same thing happened on my non-rooted Verizon S3 after using Phone Info app. Verizon tech said my phone was defective. When I went into Best Buy, they started switching my phone to a new S3 and it still did it...found it was the sim card. After I got a new one, it's been working ever since.
I have posted the fix in about 4 other threads...you need to reprovision your device with the dialer code

This wipes data so have a nandroid ready.
For the millionth time avoid the beans rom and the jellybomb theme.

I don't think that phone info app has been updated in years. Was never meant for new ultra high end phones. And not to sound rude but those menus were never meant for us to play with.

That menu is how I ****in' ripped off VZW and their tethering app for the longest time with my old X2 before I got pissed off at it's random disconnects and just started using wifi tether for root users.
Ahhh.. the memories. Good times.
idk if this is the same but i used the phone info app on my fascinate and changed it and couldnt get 3g so i went to mobile networks under wireless and networks
in settings and clicked data enabled
I haven't had any problems with the phone info app! Use it daily and it's never gotten stuck on 3g.

Id say delete the phone info app or wait until it's updated to be compatible with jellybean. 3g is almost then same as lte anyways at least with my phone I almost always have a strong lte signal. The s4 chip in the gs3 was designed to be a power saver on lte compared to older chips

Ok, so if I delete the app is my phone still stuck in 3g mode somewhere in else in the phone then? I guess what I mean is does deleting app force the phone to run off the APN settings? And if this still doesn't work can I use the re-provision code ( *2767*3855#) that I saw earlier in the thread? Finally is there a way to simply check if my SIM card is screwed?

[Q] Will a different radio fix this?

Hi everyone, I'm running CM10.0.0 Skyrocket with UCLD2 modem. I live in Jupiter, FL and when I am traveling through town and pass through areas that switch between HSPA, 3G, and 4G, I often have to toggle airplane mode to get data back. Is this due to my radio? I was doing research in the forum about the various radios and I couldn't find a definitive comparison of the various modems to each other with a chronology of release. I'd guess that newer modems are better, but then I read that sometimes that's not the case. Anyone care to weigh in on why I lose data connection when traveling through different data zones? btw i checked my APN settings and theyre fine.
I too run into the same issue but when I'm at work I know that if you running jb data loss has been known to be an issue with it yes the newer the modem can potentially fix or issue depending on situation best option is test

Just an update, things still seem good with CI3 compared to my old radio. Only thing I notice is it doesn't really like 4G data, it'll say 4G and have good bars, and I can make and receive calls fine. But if I go online it'll stall, and I'll watch it struggle and then swap to H+ and be fine. That’s the only remaining quirk. Not sure why it's doing that.

Not sending or receiving SMS/MMS and data

I've had a problem with my skyrocket for quite some time now. No matter which radio, ROM, or kernel I use the data will be hit and miss and so won't phone calls and messaging. I've already had one skyrocket replaced because of this issue and even got a replacement SIM card to no avail. I get full bars of H+ service. I've tried adding different APNs as well. The AT&T store is obviously stumped (they are basically worthless) and phone support is no better. I was wondering if anyone knew of this problem and what caused it or a way to fix it.
