Always roaming

Hi, since I got my Galaxy s3, I'm always roaming. I didn't have to stray too far away from the store before the roaming started to happen. It seems that if I do not have 3g, or 4g I'm constantly roaming. I have read on here that there is a way to fix the always roaming issue, but I didn't know if it applied to flashing a bad rom and then getting the always on roaming message. Mine has been like this since day 1 when I bought the phone at completely stock settings. I recently flashed CleanROM, and still have the always on roaming messages.
Should I attempt to use this application, or would I risk doing something terrible to the phone?

what prl do you have? any just to make sure what carrier?
Different prl's can cause it to roam. You may can pull battery and sim and sdcard, wait 30 sec or so reinstall any boot. Then check prl again, see if it changes.

What is PRL? I do have Verizon. .. I also have a nationwide plan, so I know for certain I'm not being charged for roaming, it just shows that I am all the time.

"HOME-ONLY roam setting on touch wiz roms like on CM based roms
New to posting on here, so be patient... I have been flashing roms however since the Motorola droid 1 and love the mods we can do to our phones. Now I have a Samsung Galaxy S3, flashed to CleanRom, newest version as of this date. I love the battery life on this Rom but work near the Mexican border where it easily switches to roaming. My question is that on CM roms I'm able to go into roaming settings and select either Automatic (default) or Home Only which will prevent anything but a Verizon signal. Works awesome. I don't know why this is unique to CM or AOSP roms and not touch wiz. Is there a way we can have that added or even an app that will do that very thing? Sometimes I have to just backup my rom and flash CM just to use my phone without roaming on to the Mexican cell tower. It's very frustrating. Thanks for any advice.
If this needs to be in its own thread, could someone let me know and help me out with that?
Thanks, Scott.

MMS over WiFi?

I'm wondering if this is a problem across the board. Lately in have been running a few different ROMs. Hyperdrive, moar and the most recent moar 5.0.1. I have noticed that my MMS won't go through while I am on WiFi. I don't know if this has been a problem for a while and I haven't noticed it. I really like the app textra, and unjust started using it the other day. I thought that was the issue. Uninstalled it and I am still having the problem.
Does anyone know how to fix this?

I really hope someone has a cure for this because it has been driving me insane. I shouldn't have to turn off wifi every time I want to send an mms to someone!
I'm on MOAR 5.0 v13

I'm thinking it's a rom issue because I just wiped my phone and installed cyanogenmod and I can send and receive mms messages over wifi without any trouble

are u using a network extender by chance when your on WiFi?

I always thought it was a network thing. I thought they required you to send and receive MMS through the cell towers because they're stored at Verizon servers before being passed along to the recipient. I had the same issue on my LG Ally, haven't tried MMS over WiFi on my gs3, but now I'm curious.

No, I'm not using a network extender. Interesting thing tho. MMS will not go thru at all on MOAR or Hyperdrive. I flashed bonestock 3.1 and when I send an MMS over wifi, the 4G turns on (so now the wifi icon and 4G are on) and it will send the MMS.......hmmmmmm

MMS / SMS are both sent over data networks, as this is the only way VZW can count how many you send, thus being able to bill those who do not have unlimited text messages. (this came from a VZW rep when i called in to get a work order on my phone, as mine wouldn't work)
When the S3 first came out, there was an issue with the devices as a whole, fully stock and unrooted, having problems sending text messages when the phone was on WIFI. The process is, when you hit send, it will shut off your WIFI, switch to data, send message, and then switch back to WIFI without you noticing it.
however, in the beginning, there was an issue with the phone doing this. AND this was even before rooting the phone. VZW and Samsung had to do a fix for their radios to get the phone to work correctly.
so what you are probably seeing, is an issue with that switching, not that the message won't go over WIFI, cuz unless these DEVs have figured out how to make messages go over internet instead of data network, then the issue is a ROM issue with the switch.
hope that makes sense...

Unfortunately, this is the answer that is most often given, but not very helpful (no offense). I think the majority of people with the issue at this point understand that MMS is sent via data networks by design, the problem is, it is not functioning properly. It is NOT shutting off the WiFi, therefore it is not sending at all. I've had different periods of success, where it'll work for a week, then back to the same ****. I've never rooted my phone, so it's a stock ROM issue that still remains.

always had issues sending MMS messages on roms other than stock when I was at home with my network extender...I kept messing with the APN settings last night... I changed the other thing to GSM and tried to connect to at & t towers.. after it failed only then it would have multiple choices of APN settings ..I have all the roaming options checked and the LTE/CDMA is checked...I've been able to send MMS messages with no problem now.

Just an update I'm on liquid smooth 4.2.2 and it automatically turns network data on if I have it off in order to receive/send mms. This is what I was looking for.

[Q] All CM versions - dodgy 3g and stuttering during calls

I've tried CM 7, 10.1 and 10.2 on my Galaxy S 4G (SGH-T959V).
I invariably get this problem where during calls, the audio cuts in and out (approx. every second word in a conversation is lost). Sometimes there's no sound at all, and I've had incoming calls not get through too.
Also, there are problems with 3g. Typically it doesn't work at all (on CM 10.2 it does work sometimes), and the only way to get mobile internet working is to enable the "Use only 2g networks" option in the Android settings.
In CM versions prior to 10.2, I wouldn't even be able to see any of my APNs in the list, or be able to add any, unless I had selected this 2g option, at which point they would magically re-appear. in CM 10.2 I am able to have APNs in the list and 3g works for a while, but then stops working. Needless to say, I've been double-checking my APN settings.
I've also tried a bunch of different modems, but it makes little or no difference. I got the modems from here:
http://forum.xda-developers.com/showthread.php?t=1192436
Any suggestions? I take it that the behaviour I'm experiencing is not normal?

Seems like the radio of your phone is messed up since you've tried many modems and ROMs. Did you get good signals on stock GB?

Yes, confusingly I've got no problems at all on stock roms of Android 2.1.1 and 2.3.6. I've switched between these and CM many times, and the behaviour is completely consistent - calls and 3g are dodgy on CM and fine on the stock roms.
Anything else I can try? I'm in New Zealand, and the phone is imported from Korea I think. It's branded T-Mobile, and is a SGH-T959V.

No ideas? Other people aren't experiencing this same problem though, right?

none here....sorry!

It's a weird problem for sure. I would guess hardware, or a sim card issue. Maybe it's just bad service. Not many people would know if the problem were specific to New Zealand.

[Q] Please help AOSP Roms Roaming on Network Extender

I have a rooted Samsung Galaxy S3 on Verizon's Network .I"m on a Verizon network extender at home and everytime I've installed any AOSP ROMs (Cyonogen Mod,Paranoid Android,Carbon ,Pacman etc,) my phone goes into roaming ,so I don't have a data connection or a phone connection, in my home with any of these ROM's. Outside of the network extender, the ROM's work. Currently I"m running Touchwiz Rom Jellybeans version 19. Stock or any Touchwiz ROM's work when I"m on the network extender. I've searched for a solution and have found none. I have owned my Galaxy S3 for over a year and haven't been able to run any of these ROM's because of the network extender issues. It's been very frustrating ,can someone please help with the situation?

I have to use a network extender at home as well. It's an older version so it doesn't handle data. I've used it on both TW and AOSP Roms without a problem, so what you have should work.
On AOSP roms, do you get the two tone note when you try to call? You should only need to dial #48 to register with it and then call out.

There are two different network extender models. On the older one, there is no data connection. The newer one offers 3G as well as voice I believe. So if you're on the older model you won't have network data and will have to rely on wifi. When you dial out, if you hear 2 tones before it begins to ring, then you're operating off the extender.
As long as you're on a stable version of a ROM, it shouldn't have any significant impact. I've used several TW and AOSP roms without noticing any real difference.

Hi, thank you for responding ,I appreciate you taking the time to answer. I've checked with Verizon and I"m on the newer network extender .On stock or Touchwiz ROM"s I do get a phone connection and 3G. I also get the the two tones when I dial a number before it connects. From what was explained to me that means I"m under the network extender. When I dial # 48 on an AOSP or TW ROM, it tells me that I'm under the network extender's connection.
95% of the ROM's I've used have been stable. The others have been Cyonogen Mod nightly's . On my Droid Razor Maxx,when running and AOSP ROM, I never had these issues.

In CM under
Settings > Wireless & Networks > More > Mobile networks
Do you have the data roaming options selected?

No, I've gone into mobile networks and changed it manually, rebooted and the "R" for roaming as shown in the photos is still there. I've manually forced it into 3g only and it remains the same. No data connection

Update: Currently I am running an AOSP Rom (CM 10.2 09-19-2013) and it's working. To get it to work, I installed the last ICS OTA modem (the VRLHE) and I am now getting data at home under the network extender. No more "R" for roaming! The modem is not as strong as the Jelly Bean VRBMF1 modem, but it's working. I still can't get any AOSP roms to work on JB modems and I don't know why. I was thinking of contacting the CM team for a possible solution. I am still glad it's working even though it's on an old radio.

I had the same issue two days ago when I flashed to the latest MIUI Rom. Here's how I fixed it.
Go into settings, mobile networks, make sure subscription is set to SIM. After that open the phone, type *#*#4636#*#* make sure it's set to LTE/CDMA/AUTO
Reboot phone and all should be well.

HTC ONE APN problems after Root

Hi Guys,
Just switched over from the Iphone and liking the Android platform so far. So in my tinkering quest, I think something got screwed up with my APN.
I flashed ViperOne 3.1 to my HTC One (T-Mobile phone, but I am using an AT&T SIM) with 4.3. Radio. 4A.21.3263.03 with the latest firmware from Tmobile (side note, Im still not sure if/how the firmware changes when flashing a new/custom ROM).
Anyway, I flashed Viperone and everything went fine and updated the new APN for ATT. With the stock phone, I had been using the "pta" APN and got great reception and LTE speeds. With the Viperone initial flash, same reception, same speeds.
Next, I realized I didn't install the Superuser stuff so I thought I had to reflash everything...which I did. On the 2nd go around, now I can't get the pta APN to work. I get cell service (same reception as before with full bars, but no data). The only way to get data and cell is use the phone APN but cell is 3G (>1mb) and 1 bar at best.
The only thing I remember doing that could have possibly screwed something up inbetween the two flashes of Viperone, is that I installed AdAway. Not sure it this would effect anything or not.
I've also tried totally wiping the phone and installing Viperone for a third time via a sideload. I have not tried going back to a completely, locked stock phone yet. Also, tried loading AndroidRevoltion but same deal. But given I am a noob, I am still a bit worried about screwing something else up flashing back to a stock locked TMobile phone.
Any ideas on how to fix the APN issues? I have tried all settings in this thread: http://forum.xda-developers.com/showthread.php?t=2172110
As well as a couple others and combos, but nada.

Anybody? Nobody?
Some more info, I took my phone down the street and messed around a bit at a local coffee shop. I was amazed when I didn't change anything and I got a whopping 46mb downspeed. Haven't really seen that in my area. Still only had 2 signal bars when everywhere else is usual 5. I am in San Diego so coverage is never an issue. Anyway, I then traveled about 10 blocks away to run an errand and it dropped back down to under 1mb. Same 1-2 bars. Something is definitely funky. The phone and data works. talking on it seems fine, just doing any network data stuff is very slow other than that one instance.
