I was in a building and had full bars but could not make a call, it kept saying "not registered on network". so i selected an ATT network and when i try to switch back it says "error searching for networks". also when i hit "select automatically" it sits on the "automatic registration" screen until the end of time. anyone have any ideas? I cant make calls, or get data. I can use WIFI fine, and even WIFI calling.
Stock ICS rom with faux Kernel. I had some system apps frozen with TB but i defrosted them all and restarted, problem remains.
Disabled WIFI calling, ReEnabled WIFI calling, then disabled it again and when I disabled it the last time I had full bars, then I just selected network automatically, worked real quick and I had 4G back too...not sure what caused it but its good now.
It's normal. Sgs3 can't roam on other towers. If you have T-Mobile it will only connect to T-Mobile towers. Have the same issue with a few different sgs3 phones. Latest being unlocked an using an at&t SIM and it does the same thing, will only connect to at&t towers. No roaming on other towers.

I think it won't roam if there's a tmobile tower detected. If there are no tmob towers it should let you roam.

Would that would have caused no bars and no cell data in my house later that day too? My house always has full bards and ive been getting 18Mb down on 4g there too, yet i had nothing.

Roaming is not device dependent. It's cell tower dependent. Each area is zoned. If T-Mobile has an agreement in said area with att, then you can roam. If the tower you are near is an att tower and there are no roaming agreements, then you won't be allowed to roam. And as the doc says, you most certainly will not be allowed to roam if there is T-Mobile service. But I hope and feel optimistic about the metro PCs merger. I feel that will greatly allow us to have a deeper area of coverage as well as more areas having service.

Are you reporting zero coverage in your home when you used to get full 4g? Have you tried moving to another location and seeing if it worked?
Or are you saying you have service but it's just not making phone calls and connecting to data?

Until I turned wifi calling off, on, and and off again..... I had 0 service. I started at the hospital, and and remained when I went home, about 2 hours.... Reboots did not affect it..... I originally turned on wifi calling when I went nto the hospital because there was no service, but they have wifi..... But even when I left the hospital, I still didn't have service for hours, until I switched wifi calling off, and on, and and off again.... Then all of the sudden full signal and 4G came back. I need to mention that outside of the hospital in have had nearly full signal strength everywhere in my county including my home before and after this incident.

Sounds to me like either the wifi calling feature got hung somehow leaving you stuck sorta in between it shutting off and the cellular side turning bback on (if that even makes sense!), or there were some issues with the tower in the area, and once maintenance was complete, you got your signal back.
Just guessing here!

Hello,
I have been around for a while, since my htc hero. And I've trusted xda to fix the many issues that manufacturers leave in. However the are a few issues with my new Galaxy S III that are driving me mad and if I can't fix them I may have to return it.
So far my speed is terrible. My 3g speed is half that of my wife's Epic touch. My 4g speeds are fine but will randomly switch to 3g (and with lte there is no refresh button like wimax, so I have to use airplane mode). And 4g is slower than 3g when I try to download from the play store but fine in the browser.
If anyone can help that would be great. I can't search all that well from the app and I am on stock tw 4.1 just rooted. I already fix all of the prl updates and stuff.
Also sometimes a green checkmark appears in my notification bar and says preparing network.
Other than this annoying network issue I really like this phone. I would hate to have to return it for the lg optimus G

Your wife's phone us on wimax yours is on lte. What you explained sounds like lte towers are being worked on and upgraded near you. Lack of signal going into and out I went through that for about 4 weeks then lte lite up perfectly after that.

For anyone having issues with getting disconnected from 3g network. If you find that you are continuously getting disconnected from the 3g network on Sprint, goto your network settings and change your preferred network setting from lte/cdma to CDMA only. That should keep you on the 3g network without having to continuously reboot all the time. It's not a problem with your Rom I think it's an issue with the lte network. Being that it may not be up and running in your town. Yes they are advertising it but it is not online across the entire country yet.

Turn off the Sprint Connections optimizer.
I was reading this in a different place. I flashed the newest modem (ma4), which works well. I'm on prl 25010 but I believe the one mentioned was 25013. I show the 4g lte available but my phone has never connected. I was wondering if I have to update prl also to be able to connect to lte. Also heard the new airave (mine is on the way) broadcasts lte 800?
Sent from my SPH-L710 using xda premium
Airave doesn't broadcast lte I have one and it only does 3g sadly but if your not getting 4g lte when you are in an area where it is available then maybe you should go into settings then hit more settings then tap mobile networks and make sure you are on CDMA/LTE and if you already are toggle it back to CDMA reboot then change it back to CDMA/LTE and reboot again and see if you get LTE if no try updating your data profile since prl are associated with 3g internet and roaming only I believe it shouldn't matter but I would always update both just in case

Actually, the PRL can enable and disable LTE, but I don't think there's a single PRL for the GS3 with LTE disabled. 800MHz 1x is a different story. Each new PRL since about 25006 or so has been gradually adding more 800MHz markets.
Also, even if an airave did broadcast LTE, what's the point if it's still using your home internet connection? You may as well just connect to WiFi. And as for LTE 800 on an airave, that's even more useless because the GS3 doesn't support 800MHz LTE, only 800MHz 1x.
I have 25012 now from last night.

Since 25012 I cannot connect to LTE now. Was working great on 25010.
It is probably a limiting PRL to reduce data traffic in certain areas for maintenance issues or Sprint released the wrong PRL like when I had an evo 3d a year ago.

Technically the PRL does not effect your normal cell service with sprint towers only if sprint releases a bad PRL. Now if sprint has a local roaming agreement with another cell site company it would affect your service. This is my understanding I maybe wrong.

has anyone had the issue where their phone won't connect back to 3g data?
when I reboot my phone 3g will work until wifi kicks in. after I turn wifi off 3g comes back, I can call and text but will not download any data.
I have tried Odin back to stock. wiped everything including recovery. I have tried flashing every combination of modems and kernels. all same.
however one thing I will note. I have not been able to get a successful modem flashed in Odin. it keeps failing. so I flash in twrp.
I also wiped the activation data via ##732# or something like that. had sprint reactivate my phone too..
perhaps someone could shed some light on this?

I just got my Note 2 like 5 days ago and mine does the same thing. Its very annoying and its gonna be exchanged today for that and other reasons.
Sent from my SCH-I535 using xda premium
hmm. I wonder if it's network related..
is your phone stock?
-Wizzle
Okay here is the skinny. It is network related. My wife's stock s3 does the same thing. If you are in an area without lte and your phone under mobile settings is selected to lte/evdo/cdma it will connect to ephrd13. Which is enhanced 3g. When you come off wifi or a phone call sometime it will not reconnect. You can toggle data a few times and it will reconnect.
To solve this issue, under mobile settings I select evdo only setting being that I do not have lte in my area. There is no change in speed between the 2 3g networks.
This info is from self diagnosing the rooted note 2, a stock photon, and a stock s3.
I have had sprint reset the phones as well as the ##data# trick.

When I say evdo only I meant cdma only. Ehrpd13 is the handshaking 3g for lte. Some areas have lte in the towers but no ehrpd13 so the lte is not turned on yet. Basically ehrpd13 and lte are like cookies and cream lol.

When the 4g network matures as it will the 4g will get better as the 3g.
You can always go to I think s4gru.com. That site shows when and where lte will become available. Plus they will be able to help you better there than xda.
As for sprint customer service, they are laughable at best. 4 people I spoke with didn't know what ehrpd13 was lol.

I guess T-Mobile recently updated my tower to lte in past couple weeks. I'm rocking some great speeds, but when I get a phone call it drops the lte and goes back to 4g.
It stays in 4g after I get off the phone and doesn't come back. I have restarted... gone in and out of flight mode. Nothing... when I leave the area and come back or wake up in the morning... then I get lte back again.
Any idea on this?
I'm rooted, stock, wanam, uninstalled knox and carrier iq btw.
Thanks for any assistance

You can't make phone calls on LTE yet with T-Mobile. Thats why it drops to 4g(HSPA+) which allows calls. Not sure why it would not go back to LTE, maybe a sim card problem or a phone problem. I do not have any problems with going from 4g to LTE after calls. I have wanam, no knox, and no carrier iq as well. Are you on stock rom or a moded stock rom. Have you just removed knox and carrirer iq on stock rom?
I'm stock. It could actually be a SIM card issue. I'm using the same SIM card I had from my old galaxy s. I had to cut it to fit the note. Hmmm.. I think that's as good as any place to start.
It could also just be this tower is finicky. Maybe it's not 100% up and running yet. Just wish it would lock onto lte after the call again. It's so choice having those speeds!
Thanks for the SIM suggestion. I'll let you know how it goes.

Is your lte connection stronger than your 4g connection. Because even though it may be faster it always goes with the most reliable connection.
If I know I have lte I just quickly go into dialer and change it to lte only and then back to lte/wcdma and it'll stick to lte afterwards

Couldnt one simply use 4G toggle app?
I tried toggling 4G... going into and out of flight mode... taking the battery out and restarting... going into GSM only and then back to auto select.. Nothing worked.
The method I described above apparently forces LTE only mode and somehow causes it to stick on LTE after going back to Automatic.
I've been doing it all day with great success. It would be nice if it automatic went back to LTE, but in the meantime this is a solution where there wasn't one before.
Sent from my SM-N900T using Tapatalk
It's because they just recently updated the tower. I was having the same issue in my area. I thought it was the phone and had it replaced. I finally spoke to someone at T-Mobile who knew what they were talking about. He said that it takes them months to tweak the tower until they get the optimum signal. Once that happens, you should go back to LTE after a call.
