No service-Selected network unavailable - YotaPhone

Any idea how to fix this problem? I tired to change "Preferred network type", reboot, select network manually. Nothing helps
Yesterday i had several times that suddenly the message "No SIM card available" appears, but after reboot everything was fine.

It was my provider' network. It is down. With Yotaphone's hardware and software everything is fine. Yotaphone is great!

Omnia II-After Factory settings Reset-No Network-

I have done the RESET of Samsung Omnia II. After restarting it, i starting facing issue on NOT IDENTIFYING ANY NETWORK SIGNALS.
Process::
Using Settings > Memory Settings > ClearMemory and by typing 1234 password.
After restarting, I started facing the trouble on Network signals. Its not catching any network eventhough other phones showing 100% signal coverage.
In intial set up, it is showing Data connection > Airtel IND
But after starting, it is not showing any Signals or Network operator.
I tried setting manually in Settings > Network Options > manual. Here it is showing either LIMITED NETWORK, NO SIGNAL OR Network registry error.
I tried changing Various operator sim cards but still same problem.
Problem: Seems to some important firmware related to Network is missing after reset. Please share the same if any such available.
Note: this phone I bought in Singapore and using currently in India.
Please guide me what went wrong. How to get signals on my mobile.

I have this problem too. Could you solve this problem until now???
Dunno if it will be of any help, but you can try this method for hard resetting properly (that built in hard reset function is not 100% a hard reset)
Dial this code:
*2767*3855#
The phone will freeze and reboot.
Once it reaches the "tap to calibrate screen" do not proceed and just leave the phone untouched: it will reboot once more.
After the second reboot, proceed as normal.
This should really hard reset the device.... hope it will help with your problem

Network Connections Errors

Hello everyone!
I bought Atrix recently and since purchase it was with Android 2.3.4 and the only issue I had was two random reboots and few "network connections errors" messages and brief lost of my Data Connection over 3G network. But yesterday I had that same message and since then my 3G is gone... Nothing helped - reboot, deleting APS and restoring'em, pulling SIM...
When I go to Settings → About phone → Status, Moble network state is "Disconnected".
I don't wanna root my phone in order to reflash custom or stock rom.
Can someone give me an advice or share solution if he has experienced same issue.
Cheers and Thanks in advance!
O.K. I fixed it. just dialed *#*#4636#*#* to go check DNS but I noticed that "set preferred network type" was set to "Unknown" so I put it back to WCDMA only.

[Q] Signal lost

hello all
My phone will lose the network signal and respond to any attempt to make a call with 'No Network Available' trying serch network "Error Seach"..
I have found that turning on Aeroplane Mode, then turning this off again wakes the phone up and it finds my home network (Telcel/mexico) immediately or sometimes does not return need extract sim or reboot.
another problem is that when I make a call not heard anything
Problem software?
Is there a bug in the latest release that others have noticed, or is it the view of the experts here that the phone has a defect?
I´m trying chagen option dial pad *#*#4636#*#* an "phone information" find and change "preferred network type" to "LTE/GSM/CDMA auto (PRL)" and reboot phone after changes not save
Thanks,
Sorry google translade

Unable to enter mobile netwerk menu under wireless and networks

Hello,
I have got a problem with my Huawei P8 GRA-L09.
Everything was just fine until someone told me to enter *#0011# in the dialer. The phone said something about USSD code .
From that moment the 4G LTE option disappeard under the prefered network type. I only had 2G, 3G and 2G 3G.
I was unable to get 4G LTE back, so I gave the phone a hard reset. After that I have 4G again.
But I am unable to go in the mobile network menu. If I tap it the connection seems to reset and nothing else hapens.
I tried to reload the firmware from SD card, but it fails at 95%
Does anyonen know how I can fix this? The phone seems to work fine, but I would like to get the menu working again.
Kind regards,
Marcel Voorbraak

and signal then disappeared.
I tried to inter sim uim setting but I can't because the setting page can't be interred (it say no sim uim card)
What I can do
Restart phone and quickly go to sim setting and sllect network manually
Can't search cdma it automatically
But I sheached GSM in this slot (3 networks avillabe)
as always signal listed
But the page setting still and I choose this time searching cdma networks
In this point the signal comebacks
And I can dial send messages
..
What happens. I will wait days to see
But back, menu buttons don't work
UPDATE:
after restarting phone or use airplane mode
the network lost again
And i must repeat the search as explained above.
