[Q] Plz help me for Asia network?

hello
i am having a HTC Desire Z/G2 with T-mobile
i am from india, i am connecting to BSNL sim card and phone is not connecting to network. also the reliance mobile network is coming and going., no fluent network is getting.
please help me ?
Thanks Regards

Is the phone SIM unlocked?
Can you make a call or send SMS, or you can't connect at all (voice and data)?

might just be a bsnl problem you do know that bsnl sucks right, try another sim card from some other gsm network also set your phone to 2g only mode and see if it catches a signal as a last resort factory reset your phone.

[Q] Can any genius solve my problem

HI, I am using Micromax canvas 4 from last 5 months. From last 3 months I am facing coverage issue in my home town. I am using Airtel network. The cell doesn't catch good range in my home only. Also many times calls get dropped. But when I tried same sim in other cell, it catches good network and calls to didn't get drop. Same is the issue with GPRS. GPRS too didn't connect quickly and transfer data very slowly but other devices don't give these problems with same sim. I had complained to Airtel and their engineer didn't find any problem in their network. Very interesting is that when I move outside my town, the same cell canvas 4 doesn't give any problem. It works perfectly. And please note other network doesn't give any error in my home town. I asked about this thing to one of the mobile expert about this, he told me that Airtel works on 1800mhz frequency and so canvas 4 might b not catching good range in that frequency. Can anyone help me to solve the issue?

I thought I will get the help here but no one genius replied to my query. I m very upset.

I have never heard such a problem before. I am also a Canvas 4 airtel user but i dint face any issue.
maybe you have not turned your 3G service OFF ( by default 3G service is ON on one of the SIM)
1. Goto settings>
2.wireless and networks> more
3.mobile networks>3G service >OFF
This generally occurs when you are not in a 3G circle or you may have not subscribed to the 3G services.
(Don't forget to press thanks if it solved your problem)
else use a vodafone sim in the other slot.

Bro if u will go by my advice just flash stock v14, I also had same problem solved it by flashing v14 @anupdada

@ashutosh. I m not a beginner my friend. Actually there is no problem in 3g mode. Only in 2g there is a problem. I found that if I am nearer to the tower the is no problem as such. It doesn't catch good net work if tower is at far distance.
@Alok brother how to do it. Hope I don't need to root for that. It's under warranty that's y. Pls provide me stock rom.

Which version are u on? U can check it under settings >>about phone and see the custom build version

@alok singh It's S9111B_MP_F2F3F5F8_B1_IN_MMX_14_FLASHER_USER

Brother I think no one genius here to solve our problem.

Do one thing, select ur network manually, select Airtel 3g if u have 3g plan activated else select Airtel 2g, see if this solves ur problem @anupdada @rahul110

it maybe a hardware problem or your service provider in a particular area. Do you face the same problem with other sim cards too? other than airtel? Maybe there are more number of airtel users in that area and less TDMA slots available. But i am not sure still you can try using a different sim card.
Or you can try flashing the stock rom once again. But it will wipe your data so dont forget to take backup of your phone memory or app memory. http://www.skyneel.com/2014/02/Micromax-A210-Canvas-4-get-new-update-Stock-Rom-V2.html

I have the same problem! You could solve it?

1. This may be obvious but you do have the sim in sim one?
2. Go to settings / more / cellular networks ends make sure you don't have 2g only selected.

Just update to 2.19.40.22 fw update..it has 3G stability and 3G works fine after this update..if you have older version this problem will persist ..

Same problem in my ASUS ZenFone 2 laser 550kl model finally said that customer care service executors better to check in authorised asus customer service centres the problem may occured due software issue...

Still facing this issue on Airtel Network in India at many locations. The network switches between 3G, H and H+ and hardly pages open up. Also, there are call drops when network switches from 4G to 3G/2G and 3G to 2G.

Network problem on ONE PLUS 3

I just brought a One plus 3 last week.
I m using jio in sim slot 1 and bsnl in sim slot 2.
If I select cellular data on the Jio sim, both sims have network. But if I select cellular data on Bsnl sim, jio does not get network. I m using on oxygen OS 3.2.6.
It is hardware or software problem?

thats probably because jio is a 4g only network and oneplus 3 doesn't support both sims running 4g at the same time.

But bsnl is not 4g right?

That doesn't matter, you can only set 4g network on the sim that has an active data connection. Suppose you have idea and Airtel and both have 4g, which ever sim is your data sim will be able to have 4g access.

4g and Mobile Data switch

Hey guys! So I encountered this thing today.
Jio is 4g only network and generally it offers good connectivity but in certain areas it's not that good!
So I went to settings and thought of switching my mobile data to the 2nd sim which is an airtel 4g sim.
Now airtel is 2g/3g/4g network!
But turns out if you have to switch your data to second sim, it will enable 4g on that sim and your Jio 4g only sim is hanging with no network at all!
So it seems there is no way you can keep one of your sim on 4g and use 3g network mobile data on other sim!
Is anyone having a solution to this?

simply wait for the update bro

I am too facing the same problem with my jio and Vodafone sim. I am trying to switch my Vodafone data on but not able to do so without disabling the jio sim. Has a fix been already released?
