Defy GSM network stucks in EMERGENCY MODE

Im using a Motorola Defy 2.2 MB525 (rooted)
My location: Mumbai, India.
I have IDEA sim card. Most of the time my phone network gets screwed. I was using Vodafone sim for last 8-9years, but i was facing network problem since i bought DEFY. I thought its network problem due to new vodafone 3G activation.
So I switched to IDEA with 3G. But now same here. I get no network. And if i get network, 3G doesnt gt network.
I asked other IDEA users.. they get full network.. even in washrooms.
But its only me on DEFY with EMERGENCY MODE (RED + sign).
I think its because of the FROYO update. Any HELP ? FIX ?
I hv installed Defy Baseband Switcher, network is stable now.. Hope it works fine, will update soon.
Please if any1 has more fixes feel free to post

[Q] 3G

Hi,
i m using my HTC phone in Mexico with Telcel. I bought a 3G package but I cannot receive the 3G and i m only in edge. I ahve done the configuration that i found in various webpage for Android but it doesn t change. The same thing happens with a Samsung galaxy S.. I tried the sim in an iphone and it does receive the 3G.
Is there anyone who knows if there is something t do, to configurate so that my cell can work in 3G in Mexico?
It would be very helpful.
Thanks.
Mike
Maybe your Preferred Network Type is selected Only 2G?
Thanks but i tried in Auto and also selecting WCDMA only but it only receives 2G ...
Celphone is purchased in Europe but 3G works in all other countries out of Europe..

SM-T211 Carrier issue

hello everyone, its been long since i am facing this issues (i have a workaround to tackle this issue but cant do it everytime)
as soon as i rooted tab 3 7.0 (SM T211) it started showing that there is no sim card to turn on the mobile network but calling worked pretty fine
i thought i might try different rom but not luck and on the top of that it now shows my vodafone carrier as hutch :/
can any one help me with this..?
the workaround i found is
i have to set my mobile data connection to only gsm then restart the tab if lucky it will show the vodafone in in the carrier space and then i have to change from just gsm to auto mode (gsm and wdcma)
but the problem with this is, if i restart...i have to do everything again and while in the middle of a call or surfing net on 3g, the connection drops and goes back to hutch :/
please help

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.

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.
