Hi All, i am from india and using Jio sim( 4G provider in Band 3, 5, 40). In stock rom I can see the sim can able to connect All bands,. But in all AOSP based roms the sim is not able to connect to Band 40( Always very less signal). Can anybody explain this? I tried Network signal guru App to lock the sim to band 40 only,. But the band 40 itself not listing in the app,. I can able to select band(3 or 5).
Please advise is there anybody using Band 40 in AOSP roms?

According to the HTC websites the supported LTE bands of Nexus 9 LTE version are: Bands 1,2,3,4,5,7,8,20
But when testing where only band 20 is available (using the Telia operator in Sweden) it only gets 3G. If I try the same SIM-card in my Galaxy S4 i9505 I get full signal strength of LTE/4G on band 20 (verified using the service menu).
I also tried the Tele2 operator which actually showed LTE service, but from using it in my S4 again it seems that band 7 was the strongest band in that place. When I tried Tele2 in another place which should have LTE coverage on at least band 8 and possibly band 20 it again showed 3G... (I didn't try it in the S4 as I didn't bring all the tools and adapters to use the annoying NanoSIM standard).
So does band 8 and band 20 actually work on Nexus 9? Otherwise it's going back to the shop because the lacking 4G support is not acceptable.
Hello,
I am trying to find out the way in which I can able to activate the "Service Menu" or Engineering Mode" for LYF Wind 4, Handset from Reliance Jio, supporting LTE. I need this to change the LTE band to Band 40, which might result in better DL/UL speed for Jio, as the speed presently is really poor, under the "Welcome Plan".
Any Suggestions?
Its bad for everybody mate. Just try doing an reset APN. Thats seems to improve the speed. But its consistently fast only at night. Band 40 is also TDD band so effective bandwidth goes down with number of users. Only FDD bands can give us consistent speed because each user doesnt share the band with another but get his own dedicated one instead.
Hello
Please in my country there is a 4G only data network that supports VOLTE. The network uses Band 900 and 1800, both which are supported by KATE
But I cannot lock on to the signal on my device. If I search it gets the signal, locks for about 3 secs and disconnects.
Please is there anything I can do?
NB: I've heard that it works fine on LineageOS but not on MIUI.
I prefer to stay on miui.........
Hello,
I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India)
It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier.
Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM
I unlocked Bootloader flashed old MIUI version and rooted my phone
I installed Network Guru in that
for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2
When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

My kenzo has the same issue with China Mobile(China).
Failure at msg2 for band 38, band 40 and band 41.
Currently, I lock it down to band 39 to get it work.
I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine.
Tried to flash the original ROM and modify the NV with QTSP but didn't work.

I think its an hardware issue, replacing the motherboard might be the only way
I got the H901 T-mobile locked off ebay about two years ago. I moved to India recently for work and will stay for a year. As a tmo customer i was able to permanently unlock it using the app it came with before i left the US. I bought a local sim card (Reliance Jio 4G) which uses 4G only (voLTE for calls and data). I checked the frequency bands before getting this sim and it supported 2 of the 3 bands. My problem is that it wont take to the network? (If there is a similar thread please link me to it).
Jio LTE Bands -
FD-LTE B3 (1800 +) (Supported by v10)
FD-LTE B5 (850) (Supported by v10)
TD-LTE B40 (TD 2300) (Unsupported)
I think T-mobile mostly used the 2100 band for LTE in the US. Does this mean that my phone is not taking to the 1800/850 bands or is the cell phone provided not broadcasting over them and just using the 2300 band which is unsupported by my phone?
1) Found the service code *#546368#*901# played around with the bands. (Bands 2, 3, 5 and 20 were a success on this network even though only bands 5 & 3 are supported that was weird) - No luck getting 4G
2) Then forced Band 5 & 3 cause those are my only true options and did rat selection as LTE only. - No luck getting 4G
3) Kept above settings same and went to APN. Saw missing APN and googled the settings. - Success! 4G but no text/calls active.
Trying to figure out how i can get voLTE on this now.
I found a work around with an apk from the service provider that handles calls and texts using LTE. But still cannot text or call using v10's voLTE feature. If anyone knows why i'd like to know. Otherwise, this thread can be closed.
