Engineering mode - ZTE Axon 7 Questions & Answers

Does anyone know how to access this so that I can check which LTE band I'm connected to etc?
On my LG it was simple - I just entered some numbers and symbols into the dialer.

Thanks, but that is not reliable at all. The only reliable way to tell is in engineering mode. Too many errors with those apps.

This worked on my old Sony and it seems to work here as well:
Go to your phone dialer and enter this:
*#*#4636*#*#

You need root to know the actual LTE band.

I"ve noticed the end is reverse of the beginning in the past, so I tried that and it worked.
So dial *#*#4636#*#*
But that doesn't tell me the LTE band. Maybe the Axon 7 doesn't have more information.

TD-LTE:Band 38/40/41 ,
FDD-LTE: Band 1/2/3/4/5/7/8/19/20/28AB,

I've looked around, and I don't think there is an engineering or service menu available.

Network Signal Guru: https://play.google.com/store/apps/details?id=com.qtrun.QuickTest&hl=en
While it's not engineering mode, it does have deeper radio access than tools like LTE Discovery and Signalcheck. It has the ability to turn on and off (supported) bands, allows band locking, etc.

[Q] How to get 4G/LTE on N9005

Hi,
I can't seem to figure this out, I have the N9005 and currently reside in the US. Anyone knows how to turn on the 4G/LTE on the phone? My provider has 4g/LTE here and want to be able to use 4G/LTE instead of H/H+ that shows on the phone.
Would really appreciate any help. :crying:
Thanks!

Enter *#2263# and select LTE Mode.
Check your APN settings in more networks/mobile network/APN. Make sure your on the providers LTE APN.

N9005 does not support many of the LTE frequencies in US.

1. Change with a root explorer of your choice (e.g. Root Explorer, Solid Explorer or EF File Explorer) the value“false”*in file*persist.radio.lteon*into*“true”*by way of build-in text editor of the root explorer. The file is located in root/data/property. Be sure permissions of*persist.radio.lteon*are set to rw, after altering the file save the file and make it read-only. Reboot your phone, now you will see and be able to pick the option* “LTE/WCDMA/GSM *(auto connect)” in Network Mode menu.*Important: before altering ANY file on your phone be sure you have a copy of the original, unaltered file!!!*Advantage of this solution: even after a phone reboot the option* “LTE/WCDMA/GSM *(auto connect)” will remain visible/activated.
2. When you are afraid or not tech-savvy enough to alter phone files you can download*“Advanced Signal Status” on Google Play. Start the app, go into*Advanced Info*located on bottom of the app and subsequent choose *LTE/GSM/CDMA auto (PRL) in the first sub-menu of Advanced Info. In phone Network Mode menu option* “LTE/WCDMA/GSM *(auto connect)” will still not be visible but nevertheless you will be able to use LTE/4G. Disadvantage of this solution will be that after every phone reboot you have to start “Advanced Signal Status app” and reactivate LTE/GSM/CDMA option.
Please remember that LTE/4G will only work in area’s with LTE and your phone data-plan includes the use of LTE. Good luck and have fun!

Yes I know it doesnt support many of the LTE frequencies but I thought there was a way to enable that, but I'm not sure how.

Nope, don't care about APN at this step.
APN settings does not affect at this step.

I have n9005 note 3 I had to do this to get lte option.
If you have it goto network settings and change mode to LTE.

So you have LTE mode selected in settings, but it still doesn't go past H+, and you're sure you're in a 4G area?
Firmwares and secret codes aren't going to solve this.
Your provider likely uses a different frequency than the phone supports.
You could simply look up your provider frequencies and check them against the phone specs. If they don't match, game over.

Well I have the n9005 and currently is on the T-mobile US carrier. I thought n9005 has one frequency that is the same as the T-mobile 4G/LTE unless im mistaken?

The LTE frequencies for the N9005 are 800/850/900/1800/2100/2600.
T-Mobile US uses 700/1700/1900/(2100)
The 2100 overlaps, but unfortunately T-Mobile US only uses it as a support network. Meaning it's not active by default. 1900Mhz is the main network.

Follow this topic to add required bands to your phone.
Wait a moment is your SIM is LTE/4G supported?
Some providers only allow you to connect to the 4G, if you have such contract. For example, I am customer of Tele2 in Estonia and I can not use 4G either, because I currently have such contract, which only permits me to use speeds upto HSPA+.

S4 GT-I9505 Only GSM Problem [SOLVED]

Hi
I have S4 9505 and it only connects to gsm 900 band which is EDGE in my country. I'v searched but i came up with nothing so thats why I'm asking here if any1 knows how to fix this phone to register on 1800 or 1900 LTE bands. Im pretty sure that it has to do with the modem. Is there any way to force the phone to register 1900 band through service mode *#0011#?
Thanks
If it is the modem why don't you change it?

Open the dialer and dial *#*#4636#*#*
Go to phone information and tab the menu button or the 3 dots.
Go to select radio band and try switching bands.

Did it ever work on LTE? It might be that your SIM isn't LTE capable or that your provider has yet to enable it for your number/contract. This happened to me too when I got the phone and wondered why LTE wouldn't work. Try asking them about this.
Also, I'm not on stock anymore but I think there might be a setting for network preference somewhere, something akin to limiting data only to EDGE/H+.

Adding LTE Band to MOTO G5 PLUS (XT1686)

I bought Moto G5 Plus (XT1686) from India and now I have moved to USA.
In USA i am using AT&T. Though this device support LTE ( band B1, B3, B5, B7, B40), but LTE doesn't work for this device in AT&T network and I guess it is because of support LTE band incompatibility.
I want to enable new LTE band 17 & 12 on this device (so I can use AT&T LTE band).
I am looking for detail steps which can educate me to enable LTE band 12&17 on this device.
I really appreciate your time and suggestions.

Download shortcut master
To my knowledge you can't enable or change LTE bands... Assuming this is like previous Moto devices, that information is locked deep in the device in an encrypted partition and messing with it often gives you IMEI 0 (really bad, no mobile radio at all). We tried this with numerous 3rd and 4th gen devices...
My word of advice is don't try to mod your device in this way, best case it will do nothing and worst case you brick it... Pick up a new or used device if you can't live with HSPA+ (assuming you get that). TBH, depending on where you are, HSPA can be faster than LTE on AT&T's network. lol
Thank you Stokerk - Shortcut Master - does not do much - apart from displaying my current values - again, I am looking to ADD LTE Bands.
acejavelin - Thank you - I may decide to live with this brick / It works on Just 1-band on AT&T - my current Moto G4 Play works on ALL Networks (CDMA + GSM) / Will live with this bad purchase !

4G network not available in Switzerland

Hello everyone,
I just bought a mi A1 but unfortunately the 4G network didn't appear in the list of available networks anymore. I checked the settings and 4G is the preferred network type. Also, I have LTE/UMTS (auto) as preferred network type in phone info. I tried several options with no luck.
Any help would be very appreciated, thanks!

Essential Phone Service Menu

On my old Samsung phone I could enter service menu and switch bands. I have tried to enter service menu on the Essential using *+#000000#, but I get "Connection problem or invalid MMI code". What am I missing?
Does anyone know how to switch bands on this phone, and make it stick? I'm tired of being assigned a crappy band with low signal at inappropriate times.

Yes, I have done that one. It is not the true service menu, but the test screen, where you can choose between CDMA, LTE, UMTS, etc. but that's not quite what I'm looking for. It won't stop the phone switching to a low performing frequency channel. I want to be able to switch to say band 4 or 5 or 66 and have the switch stick, disabling band 17 and 2. But thanks for the reply. The original *+#000000#, is close, but I'm missing something. Still looking.
