Hi friends,
When mobile data mode is open on my phone, if i don't touch phone for a while, it gets disconnected to 3g although there seems 3g icon and signal. After that, i am closing and opening mobile data and the problem gets resolved. But after a period same problem occurs again. My operator is the best operator in my country. There are no problems for signal.
If you can help, i will be very happy. Sorry for my bad English.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.
at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.
Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

That's a network issue, get a new sim and speak with your provider. Try the things I listed too

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything
Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..
Thanks for your help mate. Can't believe I forgot to press the thanks button [emoji2]

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.

Can't be because of the sim because I usually do this when I use the phone as a hot-spot to keep the phone in 4g. But I haven't used this option in a while, about the same time I upgraded to ob21... I just wanted to make sure it's not because of it. Thank you

Sounds good, doesn't work :laugh:
Seriously now, tried but no luck
What I know, there must exist support on Phone (ok), SIM (ok), LTE (ok) and telecom provider (nok). Phone must be on "white list". I have the same problem.
I had success eith this om SIM1 only when I first got my OP3T, but now it doesnt work any more It still switches to 3g for calls whereas before it did not, but dropped the calls.
I need LTE only often where 3g and 4g are both bad and the phone keeps rolling over between the two. I just need net at that time.
Anyone succeeded in ysimg some app for this?
Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?
Did you try calling the carrier or going online to their site and activate the phone? Not from Australia but I think it's worth a try.

Hi there. When I first got my unlocked phone and put in my Verizon sim, it worked right away. However, when I logged on to the Verizon site, it was showing my old phone with the new IMEI and the phone could receive calls but not call out. I called Verizon and asked them to activate which fixed the issue. Can't you call the carrier and ask if they can help you figure out why you can't call when on the cell network?
That is the same error I get here in the States if I try to manually connect to any roaming network (network other than T-mobile, the carrier I use).

It works on T-mobile, but it refuses to connect to any other network, and if I try manually to switch, it gives that same error message you get. Roaming is included in my plan for calls, text, and data, so it is supposed to work, but these phones have issues. I currently have the temporary fix on my phone for the T-mobile issue, so it has stopped flipping to "Emergency Calls Only" and back, but the fix prevents it from seeing other networks now. Whether it is Samsung or T-mobile who has to fix it, it needs to be fixed!
I have a 7T if I restart my phone the mobile radio power turns off and I have no service. It will magically go back on eventually but until then I get no service for about a day. new SIM cards do not help, factory reset, network reset, all that crap does not work. How to fix this?

Who's your provider? Verizon or it's MVNO?
Maybe get a new SIM from your provider?
Is it network or hardware?
Borrow a sim card from another network, preferably from someone with the same phone, and see if it still happens. If it is a hardware problem you will need to contact whoever you bought it from
