I'm extremely disappointed and frustrated from my p7p cellular connectivity, especially 3G.
It is almost nonexistent, I tried to flash multiple roms , factory images , different carriers , rooting , with no use.
I tried using network guru to force the modem to use wcdma , with no luck .. I spotted my phone using wcdma UMTS couple of times , so there is no defect in the modem .
I'm always unreachable unless I forced it to use GSM .
Any idea how to resolve it , or workaround it ?
Can I erase modemst1 /2 and check ,or it is risky ?
Please I need help
Are you in the USA? Because 3G is either phased out or will be very soon for most networks.
I have to ask "why" are you trying to use 3G? The phone is capable of 5G and in the event that 5G is spotty you can turn 5G off and use 4G/LTE exclusively which will allow you to make calls and have data access at the same time. 3G is nearly obsolete. YMMV

I know, but here in Jordan ,3g still active for calls , volte is only provided by one carrier. And naturally, you won't be able to call using only lte coz by default, when you make a call , the phone switches from lte to 3g, and when 3g is unavailable it switches to GSM . And it's going to take long time to switch between those bands. I'm mostly unreachable by this process
So by default it's NR/LTE/ wcdma / GSM ..

Meanwhile here people have no idea what volte is and carriers dont enable it by default, i have to call them to enable it for me every time i switch a phone. 3G is still the most used network for calls there, even though 4G has even better and more stable coverage. I live in the european union.
I am only familiar with 3G with Verizon in the United States with the US version of the p7p with Verizon modem. The bands associated with 3G Verizon work well when you are outside of major cities and go more rural. But, max speeds of CDMA with Verizon bands are sub optimal at 1mbps. The call quality is great though as the old Verizon commercials "can you hear me now" reflect.

Hi everyone. Quick question. I searched but didn't find much, but I was wanting to use LTE only (*#*#4636#*#*, Phone, LTE Only), and it does work but on Sprint, it disables 1x and pretends like the phone has no coverage and then does the "Searching for Service" and the battery drains like crazy. Any ideas?

That mode disables all voice and texting abilities, I don't think you can use that on a phone, especially not a phone on Sprint.
turn it back, if the phone doesn't think it has a good enough signal to use LTE, trust it and drop to 3G you'll be better off.
Use global setting for Sprint

I don't want 3g though because my phone has the power to get a signal but if it gets down to 1 bar roughly (driving between towers and I'm in a fairly big city so it's not a coverage/reception issue) and it drops to 3g, despite the fact that it'll get stronger if it waits 5 more seconds.
you can not get/make phonecalls on lte only, period. its for data only.
indeed. setting it through the dialer to lte only, makes that lte data channel the only channel, it kills the ehrpd / 1x cdma 200 ip hand-off needed for voice paging to & from the network..
but NOW i know WHY you were forcing lte only via the dialer (didn't know at 1st)
but where you are (if you're on srpint) this is what' was reported happening -
Sprint used to have "same-as-native" 3G service in the western half of Kansas via those carriers, and even used to show it as Native on their coverage maps. Then it changed to Off-Network roaming a couple years ago. They even stopped Native service along I-70 through most of Kansas and eastern Colorado. Sounds like some of those carriers aren't being too accommodating to Sprint nowadays.

i didn't know, the hometown of sprint, was having such a hard time covering, it's own home state..

That's inaccurate for me as I'm in central KS. That only applies for west KS. I'm in a native market with LTE, NV, and band 25 and 26.

ok.. central ks..
what were your settings prior, to lte only?
Just LTE/CDMA. There are times I want to set LTE only so I don't drop 4g. Of course I have service with that setting.
Sent from my Nexus 5 using xda app-developers app
you know, that going via the keypad to set LTE only you'll kill the fall back bridge to 1xrtt voice & evdo 3g, right?
& every time you want to have voice service you'd have to do the toggle to undo LTE only , then when you want it back LTE only ..
you say "you don't want evdo 3g" but the devil in the details are, you'll not have voice service ither, that way..
is it worth that trouble?
Is there a way to see and change the LTE BAND that my phone is on? Rogers support aws, 2600, 700. So I was wondering if I could manually change between them. The S5 has that option in the hidden menu, so I'm hoping I could do the same on this one.
Thanks.
The phone choose the band himself, if he don't find bands authorized by your phone company, he can't use them.

*#*#46363#*#* > Phone information > Set Preferred Network Type > 'LTE/GSM auto (PRL)'
That's as far as you can get in telling it what network to operate on. It won't let you select specific bands (at least not stock). Mine was set to 'TD-SCDMA, GSM and LTE' out of the box (international version) and since I don't plan to use my phone in China anytime soon, it didn't make sense for the phone to waste resources searching for a TD-SCDMA (China's homebrew 4G) signal. Haven't noticed much improvement to my LTE signal though, still the weakest radio I've seen in a 'flagship' in a while.
Thanks.
I am also on Rogers.
Does that mean when I am on the phone, it will revert to EDGE instead of 3g by using the LTE-edge setting?
I have major issues with reception on this phone.
LTE Works Fine but the 3G/H+ signal is awful, absolute disaster on this phone. It is extremely, extremely weak. And I lose coverage often and over 50% of the times my calls go straight to voicemail because Rogers uses 2g/3g for calling. The phone can't drop back to 2G or 3G in time to receive calls when on LTE
Rly frustrating. Have tried playing with all the settings.

I'm having issues with 3G H+ too. Dont know its CM issue or not coz I had nice H+ signals on Color OS...
Can't even use internet data. most of the time network drops after using internet for a bit.. Network just suddenly gone and after that it comes back with no internet. Internet comes back online after a while...
Really worried.. and annoyed coz can't seem to find any solve for this. Even Mahdi rom had this issue..
Ho peeps,
just a quick question. I just moved to 4G but I'm experiencing some funny issues.
On my OPO under "Mobile network settings", I changed Preferred network type from 3G to LTE (recommended) and I got 4G. But, occasionally, all of a sudden I can't make or receive phone calls anymore, even if there is good reception signal. If I change the setting back to 3G, then everything works again. So, I checked the frequencies just in case and the OPO, has we know, has LTE: Bands: 1/3/4/7/17/38/40 and Three UK (my provider) for 4G has 800 MHz (0.8 GHz) and 1800 MHz (1.8 GHz). Granted that I don't know much about frequencies, bands, MHz etc, could anybody confirm that the frequencies that the opo has are fine with the ones that Three has? If that's the case, why the opo occasionally plays up when LTE is selected?
cheers

Unless this has changed recently Three uses 2 bands for LTE(4G). One is Band 3 which the OPO supports which they use it big cities and towns and the other is Band 20 which they use in rural areas which the OPO does not support. I am guessing you are in a Band 20 area at the moment and that is why it is not working.

Well the 4g actually works, sorry maybe I wasn't clear, although it is patchy, but the issue is that often when the 4G is on, the phone doesn't allow incoming and outgoing calls even if there is full reception. When I switch off the 4g back to 3g the phone works again.

Here is something I just found on the subject.
Only two UK carriers offers LTE support with those frequencies: EE (supports band 3 & 7) and Three (supports band 3). Other carriers won't be able to support LTE coverage for the OnePlus One as they operate within band 20, which isn't supported by the phone.
Band 3 has limited usability in weaker signal areas, where it has difficulty penetrating built up areas and the interior of buildings, but it can carry more users. Band 7 (only supported by EE) offers wider coverage, as it can reach further, but cannot support as many users.
If you are an EE consumer, you wont experience any LTE problems. However, if you are a Three consumer (as I am), you may experience problems with LTE coverage, when you get outside of the major cities or in weaker signal areas within cities.
However, as Three offers extensive HSPDA+ coverage (or Advanced 3G (DC‑HSDPA) as they call it), you will still be able to get very fast data speeds (up to 42 Mbps). As Three offers 3G under the 2100MHz you will be able to get this speed with the OnePlus One in major cities and regular 3G in the rest of the UK.

thanks, that's useful, although I still wonder what causes that problem as I had it a few times now (can't make/receive calls when on LTE) as I assume the band won't have anything to do with it. I was hoping to find somebody else with that problem on Three, perhaps it is just a Three thing...
I'm on Three and I either get LTE (mainly London where I work) or H+. Either way I've never struggled, as far as I know, to receive phone calls or texts. Worried now though

I am having the same problem, have tried different serivce provider sims in my phone and they work fine, just the three sim, which I can't change as I am in a contract with them, and OPO customer service is horrendous! I have tried the sim in another phone and it works fine. I have tried to chnge to 3G only, but all the three sims are 4G enabled, so when I select the Three 3G network, the phone wont register on it, I can only register on the 4G network. I have tried installing CM11, CM12, Paranoid Android, OxygenOS and had no effect, tried safe mode, tried rooting the phone, and still no effect.
Really need a solution to this, but not finding any
To be honest this problem happens at random, at least for me, so it's difficult to find the exact cause. Touch wood I haven't had it for about a month now, but like I said, and from previous experience, it could happen anytime. Read what flumpster has found in the previous post. As for a solution, I'm not sure what to say, other than switch to 3G, wait for the 3g network to pick up and then switch back to LTE, (you might need to repeat this a couple of times if it doesn't work) that fixes it, at least temporarily.

i can't switch to 3G, when I sleect preferred network as 3G it says there is no service
Hello,
I have a Samsung Galaxy J2 SM-J200F LTE, I usually just get 3G or H+ and I want to get an option to force LTE only.
I did the *#0011# it shows me the service menu :
1- I click the "Plus" button on top-right.
2- I click "Back".
3- Then input "Q".
4- Then "Back" again.
5- Finally input "0000".
I waited for 5 minutes, nothing happened. I repeated the process many times, but still I can't get to the options to choose "LTE only".
PS : I tried *#2263# too, but it shows nothing at all.
I even tried the app "4G LTE SWITCH" . But it says that my device is not compatible.
Please guys, help me.
Is it compatible with the carriers lte? Just because it says it has lte doesn't mean it will work on every carriers lte.
Also if all you are getting is 3g or lte then you may not be in lte coverage.

Yes, it is compatible with the carriers LTE bands, and there is a strong LTE coverage because I tested it in another phone having the same carrier too.
I just need a way to lock LTE only please

You dont want that. As LTE is a data signal only. If it was only LTE you would never get a phone call or text.
If it is not connection the LTE then my next guess would be that the antenna is not strong enough.
Remember not all devices are equal. Just because one works doesnt mean others will.

Then you will have to build your own rom. Which still might not happen as the part that controls that is not open source. So it will take alot of work. And with that device you will most likely not be able to do anything about it as it is not modable and there is no device that even has the option for you to compare the code.
This is just something you may not be able to do
He wanted to enable LTE only mode. . .so there's a way you need to modify CSC features. .I tried this a year ago. . it's still working
Buy xiome Redmi 2 and above phones u can force lte stand by mode also higher version like Redmi 4 has dual sim supporting dual lte stand by mode.
Xiomi offers awesome features at lower costs...

I have been trying to get my LTE working on my Samsung S8+ SM-G955FD with Freedom mobile. I have updated the CSC to XAC and GLW from the development forums and the phone will not connect to LTE at all. However flashing it to tmobiles CSC I was able to get LTE as it uses the same band 66. I initially got LTE by selecting the network operator "Home" once I lose connection from LTE to 4G it will not automatically reconnect back to LTE unless I select the network operator again. Any suggestions on fixing this?
Same issue with Reliance JIO (India) using VO LTE. Seems the phone does not support it either (the 6GB Ram Model)
up!
my 3g does work but lte not always!
I found this article around flashing csc, it seems like it's proven to work when they are the same model eg both g950w.

I would like to ask if you rooted your phone and changed the CSC as per instructions given in the Droidview website?
If you did, and the results were not satisfactory, then you would have tripped Knox, but gained little.
I am in the same situation, and am considering rooting the phone to try the method in Droidview.
Thanks.
I got s8+ from freedom and trust me I absolutely hate their reception. On a drive home or from I get interruptions of voice call for 5+min (highway drive) in some areas. Anywhere in US call reception is hit or miss. In Canada isnt always great other. Now for LTE well, it ok if you catch LTE signal. Allot of the times im on 4g. Speed are very slow. If im lucky I get LTE. So i don't know whether its the service or the phone but im not happy. I'll pay of this phone and move back to FIDO or on US network. Freedom is garbage to me. Im all over the city, country and north america - freedom isnt great for me. Fido was excellent but i didnt get any credit on the phones, in US fido rates are very high.
