This is a question to all the Rogers Wireless users:
Does anyone know if Rogers locks their phones to 3G; or more accurately, if they set their phones so the user can't manually force GSM?
I ask because I've been trying (and failing) to find a way to set my HP iPAQ 910c to lock into GSM mode in order to save battery life. My phone settings panel lacks the "Band" tab some resources I've found talk about that allows changing of radio band, and I've tried a number of registry tweaks an an attempt to enable the tab so I can specify GSM network to no avail. The best I've been able to do is get DHR BandSwitch to set a timeout on my data connections, which helps a bit.
I have a SGS5 (SM-G900F) downgraded to Kitkat. (4.4.2)
I can use LTE with one operator A (4G shows in statusbar, speedtest measures above 50Mbits).
I bought a sim for operator B but I cannot switch to LTE mode in Mobile Data Settings -> Mobile Networks -> Network Mode. Any option with LTE is simply not available.
I tested the sim for operator B on an iPhone 6 plus, it works just fine.
I have found some guide for secret codes and walked through it to force LTE. It works, but it does not switch to 3G automatically when I receive a call (it does this with the card of operator A)
So I know that my phone does support both operators frequency bands, I can force it to work, but I want to have the convenience of automatic switching on a phone call.
Is there a list somewhere in the software that has flags for networks to enable and disable LTE options in the menu ? Can I edit this ? Where is it ?
Will updating my Android version fix this ? ( I would really prefer to avoid this, since I use SnoopSnitch )
Operator A is: Vodafone (DE), A1 (AT)
Operator B is: HoT (AT)->MVNO for T-Mobile (AT)
Any way to enable missing/hidden LTE bands ? I'm interested in Band 66 which is a superset of Band 4.
Anyone? I am in the same boat as freedom mobile recently started turning on their LTE network on grandfathered plans.
Any help would be much appreciated.
In the same boat, hope Band 66 could somehow be enabled.
Try *#546368#*990#, then navigate to Field Test, then modem settings, then LTE band selection...
Be careful to note the path of navigation and the values changed...donot try if not sure...
unwanted fiddling will result failure to identify network signals...
Anyone have succrss with above mentioned procedure?

I tried this, but no matter what band I select it says FAILED.
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
Does it work on genuine non custom stock firmware ??

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.
Is there a way to determine the current band (LTE/UMTS) that I am using with a stock phone without root? I tried the service menu (*#lgmenu#*910#) but I don't see any options available to select LTE band.
I don't know about the H910, but on some variants, in the hidden menu, you go to Field Test -> Modem Settings, and you can see an LTE Band Selection menu there. However, if there is no reset option, then I don't think it's safe to mess around with the bands there since you could be stuck on a single LTE band.
For checking what current band you're on, you can use one of those network signal analysis apps like LTE Discovery, Network Cell Info, or SignalCheck. Their main functions should work without root access.
