3845#*855# (for International model)
3845#*851# (for T-Mobile)
3845#*850# (fot AT&T)
!!! Verizon and Sprint - don't know,because when you enter model number of these two carriers nothing happens. Someone could check this out and tell me !!!

For the Tmobile variant, I can access the different networks through the standard menu.

Maybe you would like to stick it to LTE only!? :laugh:

On AT&T. Did not have RAT selection. Just a list of all LTE bands. I noticed I can not connect to LTE anymore. Is there a certain LTE band I should choose? I'm in US Florida, Orlando area. Thanks
EDIT
Just selected each band one by one, and Band 17 only one with LTE.
Thanks

You can use *#*#4636#*#* and do the same, without any problems...

These aren't mods. They should be in the General section.

Hi
I don´t have a LTE contract with my operator, but only a 3G contract.
Is this mod/tweak of any use to me?
Many Thanks

lol they are on the settings>tethering and networks>>mobile network>network mode. the selection is the same.

Is there a way to disable 3G data? I'm on the edge of a LTE network and its perfectly fine 600kb/s but It keeps switching back to 3G which only is 80kb/s and I'm about to chuck my phone.
I know LTE is strong enough to be constant, its just the phone picking the best available connection, which is very inconvenient for tethering. I switch my Airplane mode on and off and get LTE for about 5 mins.
For sprint one of the menu's is ##data## (or ##3282##) Is this the menu you'd use to access LTE only settings?

Anyone able to get the international (korean) version working on t-mobile lte?
I move around a lot, and I'm all about no contract pre-paid plans so I want a GSM phone that could get on att and tmobile bands. I currently have a Note 2 (originally on att) that was rooted to enable tmobile lte.

Did you see your model listed in the OP?
If not I would assume thats why its not working for you
That said ive seen a few guides on how to accomplish the same thing on the f400 models. A search should find them easily enough.

Have you found out how to go on HSDPA instead of 4g LTE? I also have the at&t model.

Meizu MX5 no 4G network capabilities

Hello,
I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)
I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz
Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.
I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)
I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.
I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.
Anyone here who has knowledge which could give me an answer?
Kind regards,
Martin

Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try

Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin

Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.

1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin

Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.

What were the results of this? Is it true that firmware can affect the signal received?

upgraded to the latest firmware yet?

Redmi 3s network issue

Hi guys,
I have been facing really bad network issue for redmi 3s prime.. Basically there is alot of people facing this issue.. The problem is when network drop to 2g it will not revert back to 3g or 4g.. One of the facing issue sometimes when i drop it will go to IWLAN..
The workaround tips is we use 2 sims and sacrifice our sd card..which some of us dowan to..one other tip is to open gps and open google maps and let it run on background..which will drain our battery..
Some of the user said it is kernel issue, some rom issue and some said it is hardware issue..
I hope someone here will help to sort this problem..
Thanks and best regards..

My redmi 3s network is also week

same problem here! 3s Prime international

Yeah, I'm facing also quite poor battery life due to this continuous network search / reconnecting problem. The workarounds mentioned above, using 2nd sim slot makes a difference? Don't get the tip with maps... With active GPS the reconnect 2G - 4G e.g. Works? But GPS is a known bug by (most/all) cm based roms? I really hope the official kernel source will fix it. I'm using the international version of the phone as well, with b20 lte (as long as it's connected to it )

I have tried:
- Second SIM - did not fix it, seems to work for a short period, but was down to 2G again.
- GPS - sometimes works other times no.
Issue isn't with 4G for me, only with 3G. my phone will only connect to 4G and if it drops off 4G goes straight to 2G even with full 3G reception. I have only seen it connected to 3G on the odd occasion.
Kernel source is not likely to fix it. Only fix (if software) has to be the modem firmware I think.

I had a similar problem with 3s prime purchased from India. Turns out that the network problem is caused by the lack of bands in the phone. Eg. My network runs on the 850 Mhz and 2100 Mhz but phone had 900 and 2100Mhz. so when there is a variation in the network bands I used to get call drops and no network. Even I phone used to get 2 bars in the remote area but I had no service.
There are so many versions of the phone out there. you need to be careful which one you choose. If you have network problems, my money is on the lack of bands in the hardware.
I have these right now compared to 4G: FDD LTE B1/3/7/8/20(2100/ 1800/ 2600/ 900/ 800MHz), TD-LTE B40(2300MHZ) TD-LTE 2300(band 40) FD-LTE 1800(band 3) / 850(band 5)
3G WCDMA 850/900/1900/2100MHz UMTS 2100 / 900 MHz
2G GSM 850/900/1800/1900MHz GSM 1800 / 900 MHz.
Although some models are "international version" they may not have all the bands. I cant find the links now as I already got my phone 2 weeks ago but I know for sure that I have looked at many international versions not having all the bands.

If i did this I will never have 3G as my network uses the B8 900 WCDMA band.

My operator uses 900 mhz and 2100 mhz
My phone has never, ever connected to 900 mhz band
Your operator must use two bands atleast for one connection
Try to disable it, its very easy to undo the process
Feedback me with results. Regards

Exactly the same in my case. I disabled the 2100 and it is working better. But also I still dont have any 4G network

I encounter the same problem ! Disabling all the LTE band and 3G band and leaving only the B20 LTE band and 2G band make the phone works properly in 4G.
(My Carrier is Bouygues Telecom in France. It uses the B3 and B20 band for the LTE)
This is really usefull as the phone was really so unstable i coulnd't use it normally to call or receive calls neither receiving or sending sms !
With this trick, at last i can use my phone.

(Experimental) Enabling 2xCA support support in RN4 - Mido

Mi Guys,
(Standard word of Caution: Risk of bricking your phone! Only proceed with, if you understand what you're doing)
After becoming very happy to see dev supports on our Mido, I was very desperate onto enabling LTE+ (Actual 4G) on our device over Bands 3/5/40 for Indian 4G only operator JIO.
SD625 - Actual Hardware supports it so if software support is enabled theoretically it should work...
Hence I followed this guide (https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584)
After using 549755813908 value and restarting the phone, I got very happy to see 4G+ on MIUI9. BUT BUT BUT, Phone actually doesn't aggregate with two carriers still! What happens now is whenever the phone is in Band 3 or 5, this + sign just appears.
After that, I flashed NOS ROM and even now, LTE+ appears, but actual carrier aggregation doesn't happen. I can confirm No Data Speed improvement whatsoever and can confirm same using NSG App. Pls, check Screenshots attached. Any leads are most welcome!

Band 5 has slow speed due to its 5Mhz bandwidth. Remove it and try locking on B3 or B40. I am sure it will provide you faster speeds. B3 has 10Mhz and B40 has 20Mhz bandwidth.
So i removed band 5 from my phone to have better speed and it worked.

ChinaTelecom 4G Band1+Band3
Mido Can not use it

is there any trick to use internet on 3g sim and 4g sim volter for calling only, means if i change default internet to sim other then jio , then jio should get network only for calling

While that correct, the point about this post was to enable CA in Mido. Most of the articles point 625 chipset aggregates stably over Band5 with 3/40. Anyways it doesn't aggregate on any bands, as I explained

So far nope..

May be this is due to locked nv values. When was trying to modify nv values for LTE bands i found that many other values were disabled.

You can try to enable 2CA by following my thread. But it doesn't connect 2CA as expected hence no speed improvement so far.., I have no clue what is going wrong. Thus I created this thread to gather some inputs by some experienced guys who know about this..

After becoming very happy to see dev supports on our Mido, I was very desperate onto enabling LTE+ (Actual 4G) on our device over Bands 3/5/40 for Indian 4G only operator JIO.
SD625 - Actual Hardware supports it so if software support is enabled theoretically it should work...
Hence I followed this guide (https://forum.xda-developers.com/lenovo-p2/how-to/enabled-4g-ca-p2-t3707584)
After using 549755813908 value and restarting the phone, I got very happy to see 4G+ on MIUI9. BUT BUT BUT, Phone actually doesn't aggregate with two carriers still! What happens now is whenever the phone is in Band 3 or 5, this + sign just appears.
After that, I flashed NOS ROM and even now, LTE+ appears, but actual carrier aggregation doesn't happen. I can confirm No Data Speed improvement whatsoever and can confirm same using NSG App. Pls, check Screenshots attached. Any leads are most welcome!

With this error hint, I have to close this post I guess. Don't buy Redmi Mid range you are looking to escape carrier congestion

It was proven it doesn't work, since why OP removed all the files.

It's useless even in those bands the jio speed is capped.
FUP=fair usage policy :silly:

Band 5 has slow speed due to its 5Mhz bandwidth. Remove it and try locking on B3 or B40. I am sure it will provide you faster speeds. B3 has 10Mhz and B40 has 20Mhz bandwidth.
So i removed band 5 from my phone to have better speed and it worked.

Hello Brother,
Can you please tell that how to remove band 5 from the phone and lock it on B3 and B40...??

N900L Network Data Issues LTE GSM WCDMA no automatic switching

READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid

No it doesn't, the problem is already there even before I rooted my device. Flashing stock lollipop rom on odin didn't help either

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41
https://www.frequencycheck.com/countries/philippines
I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.

According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.

I mean activate only the LTE's frquency band used by your carrier.
Check your PM.

I've already done that, but the problem with radio service network is still present, I can't make or receive any phones calls nor messages.
