[Q] Nexus 5 - Not working on particular network

Hey guys could u please help me out as my nexus 5 is not working on Airtel, but is working on tata docomo ( I stay in Hyderabad)
I'm not able to understand as both are GSM and if the phone is working on one sim , it should accept the other too
By the way the phone is imported.
Pls help.
After inserting airtel sim, the phone connects to the signal and then loses it every second

Airtel sim connectivity issue
I have got my nexus 5 last novemeber and got it for service at an authorised service centre because of a blur screen issue. Now that issue is cleared, but i find it difficult to get a good coverage for airtel network even at places where airtel has good coverage. i have tried other sim (vodafone) as well and it works perfectly. This is not an APN issue; i have used the same airtel sim for almost one year in the same device
I took this to service centre and demanded an explanation, but they are saying other sims are working fine, and hence it is an error caused by airtel network.
I took a duplicate sim and also tried my sister's airtel sim. Both instances gave the same results of poor network connectivity.
Can anyone help??
i have tried factory reset as well... so i am almost out of options...

Jio on One E8(m8sd)

Getting jio signal but not registering on network
"Your sim doesn't allow connection to this network "
I installed HTC phone.apk (v 8) from apk mirror..
(By installing this I lost control over second sim but got option to select LTE in menu )
And settings (v8) from apk mirror ..
I was using reliance 4g sim ..(not jio)
After searching networks manually
I got jio but didn't got register
Any help
Will I get jio network if I use jio sim instead of reliance
Ellaborate
How did you get that 4G option?
Tellme ill try it with my jio sim...tks
I really don't know
I installed HTC phone apk v8
Restarted phone
And selected GSM/WCDMA/LTE in mobile network
I got jio network (not registered though)
Now I got jio sim but I'm not getting network..
Really pissed off
I think there is some kind of lock protecting to get 4g on this
HTC messed up with CDMA and LTE
Because when u select LTE only it switches slot to CDMA and we cannot scan network manually
Modding phone apk to disable CDMA may work I guess
Anybody got success in running Jio on HTC E8 Dual Sim?
Tried alot to get jio sim working.. Got the sim generating bar code somehow many tricks are given, sim is activated already got the message on registered number,but still unable to get any signal for JIO, Thing is HTC has done such cruelty by locking the 4G LTE, dnt know why they do it.. Same thing with my Sony Xperia ZL, In India they lock the 4G, WTF why they do it !?

I am using moto g3 dual sim in india. Earlier, i was using 4g but 2 3 months back my phome stoppped recieving 4g network on this number.
I changed my sim twice and factory resetted my phone twice. I even tried contacting airtel customer care bit they were unable to rectify this issue.
Finally i ported out of airtel and got idea but still when i select 4g network of idea is unavailable.
I am in delhi where 4g network is available.
I have used my friends sim card of airtel and idea in the same slot, then 4g works. The issue seems to be with my number only.
Please help.

I'm unable to connect to 4G network for almost 3 months. Previously was using Postpaid Airtel Sim which worked fine. But after switching to prepaid new number which is also Airtel 4G i couldnt able to access to 4G connection.
Got help from the provider even after resetting the network settings and eve
Tried with other sim card on my device which is also not working with 4G while my sim card is working with other devices and no sim card is getting connected to 4G in my device as of now.
Is this the fault of network? Or is this Bug from the OS?
try flashing modem again from stock firmware. hope that helps

Vodafone India 4g Issue

I have honor 6X indian variant.My 4g connection works fine when I am using Reliance Jio carrier sim card.But when i switch to my vodafone simcard i am unable get 4g data speeds.I am able to view vodafone 4g network and connect to it.But when i turn on my mobile data i am only getting 2g or 3g speed.I have talked with customer care , rechecked my vodafone internet settings they all are fine.Vodafone is set as primary sim and 4g is enabled.Even my subscription plan is 4G plan i have checked.Can anyone help me to resolve this.
Update : 11/09/17
Yesterday i got update BLN-L22C675B340 , after installing there was no immediate change. but today since morning i am able to connect to 4g network all right. Don't know if it was due to carrier issue or phone software issue but its has gone away now for good.
Maybe you live in an area where Vodafone have no band of LTE that's compatible with your device
im using idea 4g. i do get 3g speed sometime when there is no 4g signal but at my home i alway have 4g i got good signal at home.

So this makes my conclusion a logical one, Vodafone doesn't provide a 4G band that's supported by your device in the area where you live!

Hide the IMEI info OP.
I use Vodafone 4g in my Honor 6x 3gb variant and its working fine...
From the screenshot you provided, we're you used to set your network manually to Vodafone 3g rather than 4g network?
