TMobile Edge to H signal???

I live on the borderline Edge and G3/H signal towers. When it switches to Edge, the G2 is EXTREMELY slow on the data.
Is there anyway to force the G2 to maintain the G3/H signal and cut out the edge? I live in Rancho Cucamonga, CA and seems that its always on edge instead of the faster speeds. Please help!

Try going to settings> mobile networks
Then make sure that "use only 2g networks" is off
Then go to access points name and select "tmobile data" if that doesn't work go to a tmo store and complain

Dont need to reboot. Also note that if your not in a 3g/4g area it will give you no signal

It's *#*#4636#*#*
GSM/Auto (PRL) seems to hold onto UMTS/HSPA longer than WCDMA (Preferred).

http://forum.xda-developers.com/showpost.php?p=6591742&postcount=2

tried to force the setting but it will go back to the wcdma preferred setting afterwards...anyone see the same?
is the Gsm/AUTO only better?

Not sure. Sometimes it seems like if I back out instead of hitting home it defaults back.

According to "T-Mobile" they said there upgrading their towers for the HSPA+ network thats why calls and text messages are not going thru sometimes........Lol!!

I just pressed back after changing the setting on mine and it's sticking.
I set it to GSM Auto (PRL) and it does seem to make a big difference in battery life (3G coverage is kinda funny in my area).

You have the # and * transposed.
Try *#*#4636#*#*. You shouldn't have to try dialing, it should immediately jump into testing mode

How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.

Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+

Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.

Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

Nice
I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.

So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.

I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?

As per the previous comment:

what is the fix to get hotspot internet sharing with the Nexus 4 ? Do i have to had a APn for 3G and swith that it to share my connection ?
I'm with the original firmware. Android 4.2.1

process com.android,phone hase stopped working
i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM

Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?

How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then

fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

[N9005] 4G was working. Now it's not. Help!

One morning when I woke up my N9005 was stuck in the boot animation. I waited a while but I had to hold the power button in to force a power off. Since then I have had no 4G at all. 4G was working before this. Can anyone suggest anything that might re-enable 4G?

Contact your operator.

It's nothing to do with my operator. I have tried two different SIMs from two different operators that both worked with 4G before. I own the phone, it came from eBay but as I said it was doing 4G before.

I already did that. At least I think I did it right. Afterwards it started up exactly as usual. There was no extra optimising apps like after an upgrade. I used Odin. Do you think I did it right? I also tried a factory reset. Still no 4G.

I can't help anyhow but what I do if I loose LTE connection I force it back with 4G Switcher app. You choose LTE only and it should connect (though I can't call or receive calls in LTE only mode) so what I do is when LTE conects I swap mode to LTE/Gsm auto and LTE stays as long as I'm on LTE area (until I somehow loose LTE again in area where LTE is available). Try that out maybe it will drive you to some new conclusions what the issue may be.

It says it's incompatible with my device!
Also it sounds like you had the situation where you lose the ability to select "LTE/WCDMA/GSM (auto connect)" and can only select "WCDMS/GSM (auto connect)". I have not lost the ability to select "LTE/WCDMA/GSM (auto connect)".

1- Yes, that's the one
2- It works on my Note 3
3- As to your assumption...well I'm not sure what you talk about. I'll explain my issue. Sometimes when I'm on LTE available area my phone connects to HDSPA+. Then I do what I described (I choose LTE on this app to force connect via LTE). I don't know do I loose "ability to select "LTE/WCDMA/GSM (auto connect)" as you said. To be specific what are you reffering with it to? To phone settings or to this app setiings? All I can choose on phone settings is 2g,3g and 4g. There's no X/Y auto connect. This option is in apps settings though and I don't really care what I loose there as long as it works when I want to force LTE with it. I'm courius why it's not compatible with your device. What phone do you have?
All in all in the end use of this app won't solve your issue permanently but with it you could make sure LTE receiver and LTE drivers on your phone system works. Then you could dig down further. You would just know that LTE works at all on your phone.

"LTE/WCDMA/GSM (auto connect)" is a setting on my phone. See my Screenshot_A.png above. It tells the phone to automatically switch between LTE (4G), WCDMA (3G) and GSM (2G). The other choices don't include 4G. I reach it by Settings / Connections / More networks / Mobile networks / Network mode.
Is you phone rooted? Mine isn't. Could that be why the app doesn't like my phone?

Further info: apparently the phone was originally Portuguese but has been flashed with UK BTU firmware. However as I said before it definitely did do 4G when I first got it. Samsung tried to tell me there was some kind of update that might has disabled 4G in the UK for this device. Sounds like a made up excuse to me.

I think so. Isn't the info in my screenshots of Samsung Phone Info Plus (in a post a further up the thread) enough to confirm?
If not could you guide me how I can check. Thanks.

I compared it to uk firmware on sammobile.com and it seems to match. Maybe you need to flash the entire uk firmware again in Odin?

Still same. I've taken it to a Samsung service centre now.

It's back, and it's working fine now. And, nice surprise, it was apparently just inside it's guarantee period so I didn't have to pay.
I'm not sure what they did but it's back on Portuguese firmware, which doesn't seem to matter, I just select English (UK) after factory reset and all is well.
Oddly the WiFi adapter has a new MAC address but the magnetic field sensor must be the original one since it's calibration is way off exactly as it was originally. (You have to calibrate it after every reboot by rotating the device in three axis if you want compass functions to work).

*Need help asap* Calling and Network instability

On Thursday, my Xiaomi Mi A1 arrived. Upon activating the sim (MetroPCS), I was faced with mobile network issues. I had problems such as dropped connections, delay in calls and interruptions during calls. I factory reset my phone about 2-3 times in attempts to fix it but it remained the same. I also cleared default apps and tried to troubleshoot it but had no luck.
Every time I make a call, it takes about 10 seconds to go through and sometimes it just drops it. Most of the time, the calls are choppy and it is hard to communicate with others. I also noticed that some people are unable to call me and it goes straight to voicemail. I have an average of 1-2 network bars. Very rarely, such as last night, I had 3-4 bars and my calls worked correctly. But that didn't last long and now I'm back to the same problems.

If you have time, you can try to flash Nougat rom if the problem still persists. Try to take the phone to your operator's store, they can do something about it.

I'm thinking of returning it. What can the operators store do about a weak signal? Its a problem with the phone I guess. MetroPCS uses Band 4 for LTE and I have a really weak connection for some reason.

Dial *#*#4636#*#* and select lte/cdma/umts (auto prl) that should solve your problem. Most Xiaomi phones come with Chinese network settings as default.

I dont know, for example my SIM card was working but had no signal, so I went to their store and they changed SIM card to newer one and everything was working fine. Sometimes SIM card can get corrupted or damaged.

No internet/data during phone calls

On Sprint's Network, unlocked bootloader & critical partitions. Anytime I even receive a notification for a phone call coming in, my LTE is dropped instantly. Deny or hang up the call, it comes back. I've read that Sprint's 3G can't handle voice and data at the same time, but this is 4G. Wifi is also completely useless on this phone as it stays connected for about 60 seconds tops.
Tried doing a complete wipe and reset to both Pie stable and Q beta 6, same exact thing. Tried all the network options in settings and nothing.
Does anyone with Sprint have working LTE during a phone call? I'm trying to figure out if it's a **** copy I got from Amazon, or the network. Thanks.

I can't say anything about Sprint, but VoLte on Verizon behaves the same way for me on Q beta 6. If the radio cycles for any reason I lose VoLte even if it shows selected. I have to toggle it in network settings for it to work.
Just curious, if you go into the phone info with *#*#4636#*#*, does it show that VoLte is provisioned?
