Ok this is probably the most frustrating thing ever.
I'm on O2 Pay as you go, in the UK and my phone just isn't connecting to the network at all!
I don't have a clue why, I can't send or receive phone calls and texts and this is a bloody big problem.
Whenever I go to search networks it comes up with all the main networks, such as Orange, t-mobile...etc. Comes up with O2 too, but whenever I click on it to register it, it says "your sim does not allow a connection to this network"!
Anyone else in the UK on O2 Pay as you go getting the same problem!?
Mine does and says that now and again, mine is contract but when its says "your sim does not allow a connection to this network"! mine just connects,
Have yo tried restarting your phone? if not try this first.

Mate I've tried everything! Restarting the phone.
Leaving the phone off for a while.
Trying to connect to other networks.
Taking the piss at the moment.
I'm just wondering if it's an O2 network problem and not a problem with my phone.
I've never had this problem before, not ever.
Had the phone since it came out.
are you with anyone else who is on 02 to check the network?
Tried taking the sim out and give it a clean? can be somthing as simple as this, other than that try flashing a new radio on to it or try a hard reset

Hi, I'm new here.
My M8 isn't receiving signal, everything else works fine, I checked the sim card in another phone and it works.
I did notice that airplane mode is stuck tuning off. Any ideas how I can fix this?
I rooted the phone (very new to rooting) but didn't go so far as to flash a mod. I unrooted the phone back to stock. It was fine for a couple of weeks, then one day randomly lost signal.
I've tried factory resetting but no luck.
Thanks

Can you try manually selecting the network in settings? Is your sim card and phone compatible?

When I go to search network operators it says no networks found, the sim came with the phone and worked fine for months until now. The SIM works in another phone just fine. Maybe it can't find network because airplane mode is stuck turning off...

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.

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..

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.

I am using mi max 128 GB. mobile data is not connecting with sim 2. With sim 1 it's connecting fine. I tried to connect only 2g also but no use. I had verified the sim with other phone and it's working fine. Both my sims are BSNL and both have working data plans. I tried removing and reinserting sim, rebooting, tinkering with *#*#4636#*#* but nothing worked. To be precise nano sim is working for data connection but micro sim slot i.e sim 2 slot sim is not working for data connection but working fine for calls and messages. Please tell me what to do?

It's a stock MIUI 8.2. The OTA update from 8.1 to 8.2 came just now and i updated. Even after update same problem is there. I had also tried with AIRTEL sim. But the data is not connecting.

I´m not on Miui to test it, but if you got to Settings -> Sim Cards you can click on Sim-Card 2 and there are some settings like prefered Sim Card Settings or something like that.There you can choose something like for data connection
I bet you've already tried that, haven't you?

I can´t give you an answer for that. I´m in Germany and here is no Xiaomi Support for their Devices. If I was you, I would flash another Rom and test it, but if you have a normal warranty you can go to the next service center and let check it by Xiaomi.

Two Sim Cards from the same network will not work. Try using a different network sim card in slot 2 and check if it works. When you use two simcards from the same network, are you able to call using sim2?
can you not select it from the bottom menu i can switch sim one or 2 but cannot use both at once
APN
From how much time you are facing this issue?
Is it appeared randomly?
Or it happened after doing something?
I can not place or receive calls unless i manually search for mobile networks and register on it again, it happens every hour or so.. Anyone else had this issue? What can i do to fix this?
Reset your Network settings.
If this not helpful try an factory reset, you will lost all your datas. So backup it.
