[Q] XOLO 3G not working - Android Q&A, Help & Troubleshooting

Hi Seniors,
I'm looking for your solutions.
I bought new XOLO Q800,
After few weeks only I found that it's not working on 3G mode.
i.e. if I select WCDMA only mode It is showing No Tower(Signal) at all.
and If I set to AUTO(WCDMA/GSM) mode it Shows signal.
In AUTO mode It connects only to EDGE not on 3G.
I tried many possibilities like flight-mode/wifi-on-off/removing -reinserting SIM .. lot..
Info may help senior to understand problem:
SIM: AIRCEL INDIA
in AUTO mode:
When I search network manually,
It shows All 2G and 3G tower in that area.
like
AIRCEL2G
AIRCEL 3G
...
..
and I'm able to Register to AIRCEL 3G in AUTO mode.
but still internet connecting to EDGE
In WCDMA only mode:
When I switch it from GSM only mode or AUTO mode to WCDMA only mode.
It Shows no Signal(Tower)
in Manual mode If i search for Network,
It Shows
AIRCEL 3G tower. but I can't Register to this AIRCEL 3G tower in WCDMA-only-Manual mode.
It says "Can't Register to the Network Right Now"
Please Help me! I will send whatever details u asks about my phone.
I sent my device to service center once for this issue. They said repair done. but I'm still facing same problem( They changed my IMEI !!! , but still same phone/screen with my screen guard)
If I contact them now, they r not responding properly.

Sorry Its Not a HW failure, Its Fault with SIM

Last Day I have fought with my Q800+SIM to found that its a 3G fault with network. not with HW device.
When i sent a msg to AIRCEL START 3G to 121. they sending me msg that 3G activated already. but they have not activated in real.
I used my 3G/4G dongle AIRTEL SIM in WCDMA only. it worked fine, later I discussed with AIrcel and confirmed that 3G not activated yet on My SIM.
Thanks those wish to Help.

Please help. I'm facing the same problem.
I also inserted the same Aircel sim in first slot and Vodafone in the second sim slot. Even Vodafone sim is not working in second sim slot. :/

Facing the similar problem
I have also same issue with my Xolo Q800.
Mobile data is not at all working in my mobile. No 2G, no 3G.
I sent an email to customer care. They said format the mobile to factory settings. I did it but still same issue.
If someone finds a solution, please reply.

Hi, I could resolve it by rooting (yes). I have rooted and and upgraded to 4.2.1.
Even now I am having a custom ROM. No issues for me. In face now both the SIM slots have 3G feature.

[Q] K900 3G problem

Hello everybody, i purchased K900 from china last month and receive it quickly. He looks very nice but i've got a problem with it. I'm on vibe rom V7 includes android 4.2.2 with french operator SOSH sim card. When i'm using 3G data mode, it doesn't work, i mean : that's impossible to open any webpage or internet connexion. I'm trying resolve the problem with APN configuration but without success. And, when i switch form 2G/GSM mode, it works, but the debit is too low to exploit data possibilities.
So, i've tried to launch internet connexion with Bouygues Telecom sim card, and 3G works fine....
I believe the problem is my K900 doesn't support SOSH frequences (Orange operator).
Anyone can explain me what's going on my phone?
Best regards.
Up?
I mean, 3g signal behavior on my k900 is lost and found constantly.....
Please help me diagnose this trouble!
Best regards

Thanks karellang but network mode still Only WCDMA....
It's surprising because SOSH (Orange) and Bouygues both use 2100MHz frequences for HSDPA.
I just bought my K900 a week ago, I'll try my B&You (Bouygues) simcard tonight and check it works.
Alright! I saw that i tried with a bgtel sim ans that works perfectly.... The signal is always There with no losts. Please someone tell me if he had a sosh sim, and the correct APN he is using for data?
Best regards...:crying:

LTE network

Having a problem here. i don't know if its the phone or the network. Im using C6833. I just changed my sim card for a GLOBE LTE sim (Philippine) ., but upon switching on LTE/WCDMA/GSM it will scan network but after 5 mins it will lost its connection and will not scan any network again.. but in a settings of WCDMA/GSM my network run smoothly., can you figure out what is the problem? thanks for your help.,
Sorry for reviving ths post, but I have a problem close to what OP has...
When I click LTE/WCDMA/GSM. It cannot detect any 4G signal, goes to 3G. Then, the option reverts back to WCDMA/GSM.
I tried the SIM card on another phone, and it can detect 4G signal.
Would appreciate any help.

S6 edge network mode issue works with gsm only. Any solution please

Dear All,
I have purchased my s6 edge device a month before. Issue is this that whenever I try to use it with wcdma or LTE (auto connect) a message appears that "not registered on network" and phone works with gsm only. Means on gsm network mode phone is working fine but on LTE or WCDMA mode there is no network and emergency calls only appears. Please help in this matter. There is no issue from network carrier side its confirmed from them.
