[Q] 3G connection doesn't work - HTC One V

I have a problem on my phone : the 3G connection doesn't work. When i'm on GSM only, no problem. But on GSM/WCDMA auto, all the connection are stopping ( Including 2G ). My APN are good, and my Simcard too ( I tried it on another phone ). I didn't have this problem at the beginning, but it started 2 or 3 weeks after. I already tried to reset my phone, but i have the same problem after !
Sometimes, when the connection doesn't crash, I have the "3G" logo on the top of the screen. Unfortunately, the connection doesn't work : the arrow to the top is on, but the arrow to the bottom is off.
I have no problem with data connection in GPRS/EDGE : it works perfectly. The problem is only on 3G

[Q] Seeing "H" symbol but no data??

I have a HOX (euro model), and it has been working for several weeks now flawlessly on AT&T here in the States. All of a sudden though, this morning I am unable to get any data over my connection.
I'm getting full bars, seeing the H symbol (sometimes it switches to 3G like normal), and I have an IP address. But I cannot seem to get any data to actually transfer.
I have rebooted the phone several times, gone to airplane mode and back, switched to GSM only and then back to GSM + WCDMA mode... and still no luck. Wifi works without a hitch.
Anybody have any ideas?
.... and I fixed it. Did a soft reset and it worked just fine.

3G disconnect, only use 2G (GSM). Help me!

I installed room ( {Rom}{ICS} Official Global CM9), after 2 days my phone's network is disconnected. I reinstall the original room 2.3.4 but only use 2G when I used dataroaming; completely unusable 3G & network global mode always (I fullwipe data before reinstalling room 2.3.4 ; radio 1.09.01.0312 & APN properly installed). Please help me how to be able to use 3G
because my phone is example:
Unfortunately, I'm having the same problems with this ROM on HSDPA that I was having on aeroevan's ROM. GSM is found immediately on boot, however, HSDPA is very flakey. It will succeed in connecting every now and again, but then randomly drops the signal and won't reconnect. I thought maybe I just had a weak 3G signal where I was testing, but I have a BB Bold for work as well and that can easily maintain a 3G connection on the same network. I also had no problem way back in the day with CM7.2, but that ship has sailed .
Also, when the phone is in WCDMA preferred mode, after a while the phone will lose all connections (usually after a reboot but not always), including to GSM and when I go to reselect my network operator I get the message "Error while searching for networks". No matter how many times I reboot the phone or switch to "GSM Only" or "GSM/WCDMA auto" it never lets me again select my network provider.
Dude you already posted the same thing in q&a why did you post here

[Q] No network data connection

Hello all,
I got my P6 for a few days and from time to time I had troubles to connect the data network (2G and 3G).
When I switch the data on, it connects to the network for 1/2 seconde and then it disconnects (the H+ symbol stays on though). Switching the data off and on again only repeats the problem.
Restarting the phone allowed me to finally have a stable connection so far but since this morning it doesn't work anymore. Removing the sim didn't help.
I'm on B125.
Anyone encountered this problem and managed to solve it?
Thanks!
I may have solved the problem.
Use tweakker from the play store to get the exact apn details for your carrier (mine is Base Belgium) and put them in the apn settings.
Since that I can connect the data without any issue (except a new bug: switching to "2g only" make the connection bug again, except if the data is switch off before and switch back on after a dozen of seconds). It seems that it is more like a carrier problem but that creates bugs only with Huawei products (source: internet).
It seems that the P6 is a very capricious phone, I love it but I wouldn't recommend it to anyone which is not an engineer!

Dual Sim issues

Hello,
I'm using two swedish providers in my phone - 3 and Telenor. Both are capable of LTE/UMTS, I'm using 3 as the primary provider for all options in the Sim settings and the Telenor one only to receive calls.
So I recognized a problem where my data connection would drop when the 'open wifi'-notification popped, I tried to disable that and it seemed fine at first. However I'm still getting data connection drops when me phone swaps from LTE to UMTS(3G/H/H+), no errors are thrown and I'm only seeing it due to no data loading within apps or disconnects in-game, the display isn't dropping the coverage indicator nor the indicator for which network is being used(3G, H, H+, LTE, 4G+). After some time the data connection returns but keeps dropping rather frequently once this pattern starts.
Airplane mode restores connectivity for a while (I haven't clocked it) but eventually the connection stops receiving data and the disconnecting pattern returns.
Calls and SMS are working as far as I've noticed so far.
Any ideas?
Edit: I've restarted the phone multiple times.
Any one got similar issues or any fix :3?

Cannot connect to cellular networks anymore "Error while searching for network"

Cannot connect to cellular networks anymore "Error while searching for network"
My phone used to work fine. Then I turned on Hotspot one day, and I don't remember if the phone restarted or not, but soon after turning on the hotspot and connecting to it, it dropped the network connection and it will not connect to cellular networks anymore.
Everything else is working fine, bluetooth, Wi-Fi. I am not getting any restarts (boot loops). Everything else is fine, I just cannot connect to cellular networks. The SIM is fine because I tried it in another phone; it works fine.
I tried everything:
Resetting the phone.
Setting to 2G, 3G, LTE.
*#*#4636#*#* > Set preferred network type, radio bands (Auto, US, Japan).
Wipe cache partition.
Nothing works. It cannot connect. Does not see any networks at all.
Do you guys have any idea? Is this a hardware failure? What else can I try to do?
