[Q] Network Dropping

I just want to check in and see if any other Inspire owners are having this issue:
I have noticed that my phone occasionally drops the network connection and doesn't get it back right away. There are two different flavors of this issue that I have experienced:
1) I was walking my dogs today and the phone suddenly dropped it's connection to AT&T completely. After a few seconds, it reconnected and everything was fine. I was in an area with good coverage and the status bar showed no connection at all.
2) When home, I leave the Wifi on. Earlier today, when I tried to make a call, it simply wouldn't dial out. Then I tried to open a web page and nothing (after turning wifi off). I had to switch airplane mode on and back off to reset the connection. I also received several text messages at once, all of which had been sent hours before (as indicated by the time stamp on the message). It's almost like the phone has an issue swapping back and forth between the carrier connection and the wifi.
Is anyone else experiencing anything like this?

As an update, I noticed that when the wifi is on, there's a check mark under the H+ symbol (rather than the up/down arrows) and when I switch off Wifi, it doesn't go away. During this time, I have no cellular data. Switching airplane mode off and on doesn't seem to work. Sometimes it recovers on its own. Other times, I have to turn the wifi off and on several times.
This is annoying. It seems to be having issues doing the hand-off between Wifi and cellular data. This is really the only issue I have with the phone. Hope they roll out a fix soon.

I had the same problem. I thought it was because I had to add my own APN. (I could not switch my plan around because it was a work SIM). This caused SMS messages to not go out and an overall bad network experience on the phone. I have since returned the phone because I need a reliable network connection and the ability to send/receive SMS messages at all times. Once a fix is found I will be back. I liked the phone alot otherwise.

Are you by any chance using the SIM from another phone? I had the exact same issue yesterday and data did not work for me until I called AT&T and had them update IMEI number from Captivate to Inspire. Hope that helps.

Nope. I made it a point to have them activate it in the AT&T store with a new sim because I had read about people having issues when they transfer their SIM. I also had and iPhone 4 previously, so transferring wasn't really an option. I'm definitely on the right data plan, too.
I left the wifi off all night and it did it to me again today. The check mark shows up under the H and it loses all data connectivity. I'm not sure what is causing this, but I'd love to know if there's some kind of workaround. I have messed with a few options (like the data always on option) and haven't had any luck.

I was using a SIM from another phone. It is the SIM card from my Work phone and I can not change the plan. It does have unlimited text and internet I just cant change it to a 4G plan. I had added the APN that is floating around here and that worked except I was having the same problem as the OP.

Like I said, my issue was very much like yours and OP's and adding cutom APN made no difference until I called AT&T and had them update IMEI on my account. Presto, all problems went away instantly. I understand that it's not an option for you, sorry

have you tried creating a new apn? try creating one using these settings.

Just did this. Thought it might have resolved it at first, but it didn't. Basically, when I put the phone down for a while, it's like the data connection goes to sleep and doesn't wake up. When I turn the screen on, there's no mobile data. Sometimes, the dual arrows are visible under the "H", but only the up arrow is lit. Other times, the check mark (meaning no data) shows up under th "H" and stays there. Switching Airplane mode off and on will reset the connection.
I hate to say it, but the phone may have to go back. I love everything else about the phone, but this bug is too major to wait for an update or fix. What good is smartphone that doesn't get data reliably?

are you running the stock rom? i haven't been using that rom much so it may behave differently than the custom roms.
i don't think its a common bug. i would see if you can get a replacement phone.

Definitely stock rom. No rooting or anything. I didn't notice this on the first day I had the phone because it was on Wifi almost all the time. I turned wifi off to test it and the issue persists. I suppose I should try resetting the phone first, though I'm not looking forward to setting it back up again. After that, I'll take it into AT&T. I'd love to keep the phone. Can't believe no one else is having this issue.

yeah, resetting it up is a pain. sorry, and i hope you get it fixed.

Just to say it again. I had the exact same problem as the OP. Maybe we both had a flaky phone?

Okay, turns out there's an issue with the AT&T tower closest to my house. I found out from a rep at AT&T. I haven't left home much at all this weekend, so I had no standard for comparison. I just verified it by turning the wifi off on my iPad and using 3G data. It has the same issue.
Of course, I had already done a factory reset and gone to the AT&T device support center, but at least my phone is fine.
As a side note: I love that Android restores your apps now. I always thought WebOS was awesome for doing that and that was what frustrated me most about Android, with as often as I swap phones.

Wow... Wish this was my problem. I switched back to my Palm Pre+ and my data works fine.

Cellular Data stops working after airplane mode or in\out of coverage return

Replicated this on 2 different Infuse 4G using 2 different SIM cards.
I notice that about 50% of the time when I come out of airplane mode, the data connectivity on the phone is gone. The only way I've been able to figure out how to restore it is to go into APN, open the apn settings page, then press save, and that seems to restore it.. yeah, annoying a little? hehe
The other time I notice it, while less frequently, is when I am out of coverage, ie an elevator or sub-teranian environment (hehe, I like that word better than basement), and then I return to coverage. turning airplane mode on then off doesn't restore it like many issues, nor does a complete reboot of the phone, so it's really strange. the only way I've been able to solve it is to go in and tap the apn settings then resave them, which obviously isn't the ideal way to resolve it.
Anyone else having this issue? I have replicated it on the 2 Samsung Infuse 4G devices I have, and they were both setup independently.

I flew the day after I got my Infuse and four days after I returned home on the next flight...No problems with airplane mode. Just playing around with it now, I'm still not encountering any issues.
I do have occasional issues that require me to enable/disable Wi-Fi...it'll only hop wi-fi spots once or twice, then I have to enable/disable wifi to get it to hop on a new one. Won't scan properly.

Are you AT&T? I'm wondering if it's something AT&T is doing to the phone then. I'm using an MVNO of ATT's sim card, so the apn that was on the phone originally was deleted and I replaced it with the new APN info.

Yes, I'm on AT&T directly (using an ancient Cingular 3G SIM)... obviously, I didn't have to change any of the APN info as a result.

I just tried my Tru Mobile (It's a global roaming voice\data sim). I changed the APN and it's doing the same thing. Bugger.
Would AT&T really script the phone to try and hassle someone for using another sim in the phone? Weird. Hopefully when a flashable ROM comes out it'll solve this issue as I never had it when using CM7 on my Inspire 4G, nor Aria, nor Captivate.

HAHA, that's funny. I always forget it's AT&T we're talking about.

I know this is an old thread, bu this happens to me too. I'm running Infused 1.6 and the same thing happens to me. Into and out of airplane mode I can receive but not send text messages. Or if I travel through an area where there is no connectivity then I receive but can't send text messages.
My fix is to restore the backup data for "[SMS/MMS Prefs Messaging 2.2.1]" using Titanium Backup.

Seems more like an issue with your sim cards than the phone.

[Q] No Edge, 3g or 4g

Last week I stopped being able to use the internet, marketplace and streaming service on my Galaxy S 4g unless I'm on wi-fi. Today I realized it appears as if I'm no longer getting edge, 3g or 4g service. I have bars, but nothing next to it telling me what network I'm on.
My phone is rooted to stock with bloat removed and has been for months. Any ideas on how to fix this?

Try toggling airplane mode. Might help to remove your SIM card & ensure the contacts are clean then reseat it.

I'm having the same issue after moving CM7 => MIUI.
I've moved back to stock ROM XXJVT, but still not able to connect to 2G/3G. Anyone help.....
Btw, I'm sure the APN settings are correct and packet data is checked.

try taking the battery out for 10min

I guess I figured it out. But it doesn't seem very logical, but hey it works.
I changed the url of my provider from "live.vodafone.com" to "live .vodafone.com" (watch the space between live and .vodafone) and all of a sudden E/G/H appeared in the status bar.

Still, double check the APN settings, make sure everything is entered in right (proxy, username, authentication type, etc). Were you able to send pictures still? You need to make sure it's not a hardware problem.

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] No data on straight talk

I tried all the setting I found online, still no data.
Got the new sim card yesterday - blue - tf64psimc4mb ($7)
Calling & texting works.
also not receiving mms

my issue is that I am using newer att sim and suddenly my speeds used to be LTE but more often than not are now indicating H or H+ and signal is weaker. started right before Thanksgiving thereabouts. I haven't even come close to the the 2.5 GB cap either.

How I fixed it..
Called straight talk, guy had me setup new apn again (same thing).
still didnt work. Then he did something (not sure what)
then he said turn off (not just restart) and turn back on.
Then it worked.
Hope this helps someone.

still can't receive mms
