jollz_04 — Wed, 07 Mar 2012 12:30:27 GMT

i am facing problem in connecting respective 2G network of any SIM in my NEO V. I have tried using 2 or 3 sims, they are working perfectly fine in other handsets but they are not working in NEO V.

Whenever i switch to 2G network and selects the respective network it says "SIM doesnt allow this connection", but it connects to 3G network.

So baiscally 2G isnt working.Even i have updated the software but still no luck.

Please kindly help me in this matter

i think you need to contact your network operator regarding this issue and see what they say
share it here

You tried other sims as well, are they all of same network carrier ??

if they are of different carrier then also you are facing this issue ?

But SIM is working perfectly fine in other handsets, so there is no problem with the network operator, n i have checked around 3 or 4 sims of different operators and still its not connecting but when i switch to 3G mode, it connects.

okhh

Suggest you to do a master reset
settings> privacy> settings reset
and after that again receive settings ( settings>sony ericsson > internet settings> accept)

one more thing, go through all your apps that controls such things such as battery defenders, managers, controllers and revise their settings, this issue could be due to some third party app also

I have just updated my phone's software and i have done that too, even factory settings too and right now there are no third party apps as there are only applications which come by default in the handset.

If the phone is not locked to this operator you could check if you get 2G signal inserting a SIM card from another operator.

What do you think about this forum? Let us know by doing this short survey.

either there isn't 2G coverage or you need a new SIM card, it happens.

It seems to be something in the baseband. I was facing the same problem in a SK17i with 2.3.4 and it was completely solved with the ICS update (baseband -72, Carrier CLARO, Brazil)

Now I'm facing the problem in a Xperia Play with 2.3.4 gingerbread, baseband -56. Tested a lot of firmwares (with different basebands - 22, 36, 56 and 64) and no one could connect 2G, in any carrier.

The major problem is the loss of signal in some areas, but there are another issues, as the battery draining fast since I'm always in 3G.

Is there any way to try SK17's baseband in Play? Can SE provide a flashable baseband for testing, at least?

Regards,

Chris

I have this same problem on my Xperia S as well.

I had rooted the phone, and was using ICS (Cyanogenmod 9.1.0) for nearly a year, without any problems. I always used to use a widget to switch from 3g network to 2g network, whenever I wasn't using 3g data (I found that this greatly improved battery life).

But suddenly, three days ago, the phone refused to switch to 2g network. It would lose network entirely when I put it into 2g mode, and would only receive 3g signal. This means, whenever 3g signal drops in the area I'm in (I live in India), the phone loses network entirely, instead of switching down to 2g from 3g.

My sim seems to work fine in other phones, and other sims seem to experience the same problem in my phone. Because of this, I used Sony's EMMA tool to restore the official Sony ROM (Jelly Bean 4.1.2) but despite changing the OS, the problem continues.

Is it a problem with the antenna? Can anybody please help with this?
