No connection with mobile network

My phone (which was bought only 2 days ago) has suddenly lost connection with mobile network. "Emergency calls only" is written on lock screen, near signal power bar there is a small red 'x'. I tried turning it off and on, tacking sim card out and putting it back in, trying to connect to mobile network manually through the settings "Service providers" (it says "Could not connect to network now. Please try again later." when I try to connect manually), changing network mode (to all possible modes). Still no luck. I can't send an sms or make a call.
What should I do?

I got similar issue but the only thing is phones randomly disconnects itself from the mobile network in some days. Then no matter you manually search for the network and try registering, it simply wont connect to any network.Your only solution is to reset the phone or turn off and on and it again auto catches your operator.

S860 and X2, Google not connecting on mobile network.

I live in Sweden. Had my S860 for 3 years and it has been working fine but some months ago it was not connecting on mobile network with crome and play store. Restart and it could work for some time the it was gone again. At the same time Hotspot, skype and OS update is working fine. Got a new sim card i november but it did not help. This was going more and more bad and finally it did not work at all. Tried to reverse OS a few steps back and still not working. So i tought that it was something to do with hardware. Now i bought a Vibe X2. Away from sweden for the moment (Saudi Arabia) but this one does the same when I try to connect. OS update working but Crome says ssl error and Play Store just wont connect. Saw some forums said it might be time and date that was wrong so i tried to change to local format but it was the same. My S860 i was waiting for 6 month before i could buy it (not for sale in Sweden) in Saudi. Haas been very pleased with it so now when it has been messing with me i had no problem to buy a new Lenovo phone. This time just waiting 3 month before i could buy it in Saudi. Hope this is something I can get some help to solve. /Nils

Hi Ragge
Can you tell me your firmware build number(for the S820 and Vibe x2) and Baseband version(for the S820)?Settings->About phone....
''Had my S860 for 3 years and it has been working fine.....Sorry, checked and it is a S820 i have.''
The S820 has been relesed in May 2013.
''Tried to reverse OS a few steps back...''
How did you do that?.
Can you install THIS ->Open the app->MTK Settings->Telephony/BandMode->SIM 1(Do the same for SIM2) and make a screenshot(Power&Volume-) ->post the screenshot here.Thanks

Impossible connecting with wireless network Netgear WNR 2000

I can not log on to my wireless network (Netgear WNR 2000) with my macbook. My other PC:s work fine and connect always. My Macbook only connect after I have restarted the router. When I use my Macbook in other places I can connect with wireless network. What is the problem?

I'm assuming that you're using the right network password! After that, the most common causes of difficulty are:
- The router not set up for DHCP and so cannot allocate an IP address to the MacBook
- The router has "MAC" Address Authentication (a security feature - don't mistake MAC for Mac[intosh]) turned on and the AirPort MAC address isn't in the pass list.
- The default "Automatic" location in System Preferences > Networks has been modified so that it no longer works.

GPS Inaccuracy With Mobile Network Enabled

I have a BB AT&T Passport. The GPS location with Mobile Network enabled is .25 - .5 mi off. If I disable Mobile Network and just use WiFi then my GPS Location is within 50 - 100 ft.

Very poor connection with wifi network with mini iPad.

I recently bought à new mini iPad. The connection with wifi network is lost very often and therefor not Stable. I tried the tips such as forgetting the network and connecting again, but that doesn't help. What can I do?

Do #5.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

One Z10 works fine, the other has problems connecting to mobile network

Hi, my wife and I both have Z10's, and we're both on the same mobile network (Wind Mobile in Canada). The wife's Z10 seems to have no problems connecting to or staying connected to Wind Mobile. Mine on the other hand seems to randomly drop the connection, or has trouble obtaining connection, and sometimes ends up roaming.
The only difference between the two Z10's is that hers is purchased through Wind Mobile itself, and it is locked to their network for the moment. I purchased mine a bit later, and I bought mine directly through Blackberry's online store, and mine is therefore unlocked. What I have to do sometimes is turn off the mobile connection, and turn it back on, and it works after I do that. However, that's annoying, as I'd rather have it automatically retry the network connection so that it doesn't go roaming within my own city.
Solved!
Go to Solution.

If you're passing by a Wind store in the near future, why not drop in and ask if they'll swap SIM cards for you? It could be something with the SIM.
In the meantime, try resetting your phone. This is equivalent to doing a battery pull and it's usually the first thing I recommend when troubleshooting an issue. Simply press and hold your power button for about 15 seconds until you see BlackBerry on your screen. Don't release the button before that and ignore anything that appears before BlackBerry.
Let us know if either of those solutions helps you.

Unable to connect to Mobile Network

Turned my blackberry off last night in the theater and now I can't connect to the mobile network - and therefore can't do anything with my blackberry. I have tried to restore network connections, but it tells me that there are no available networks due to radio being off??? How do I turn the radio back on???

Hi and welcome to the forums!
Between the two posts your are not registered on the network and your radio signal at -256 is extremely weak.
I would reboot see if your -dbm level is -100 or less and reregister the phone.
If it doesn't reregister I would make sure all your data is backed up with Desktop Manager, perform a security wipe and return the phone to the carrier.
Make sure you get a new unit as opposed to a field replacement unit or a refurbished phone. You are currently holding what will be someone else's refurbished phone, OK?
Thanks

Blend maintaining connection over mobile network

Hi there,
I've been using BB Blend (on a Lenovo laptop) by connecting my BB Z10 via an USB cable (no Wi-Fi).
Only today, BB Blend has remained connected to my handset even after I disconnect the cable. On the handset I get the message that Blend has switched to a mobile network connection ansd so it remains connected to my BB Z10.
Now, my questions are:
How and to which network does Blend on the Lenovo laptop connect? (even if it is the handset's network, how does the laptop connect?)
Is this something I should be concerned about - in terms of security?
Thanks everybody.

Hello,
When you disconnect the USB cable, the "hard line" connection between the device and the computer is of course severed. If they are both on the same "local" (e.g., no carrier data network involved) network (either WiFi or hybrid wired and WiFi), the two can communicate with each other that way. If you have set the configuration on the device to allow it to continue to be connected to the computer when the BB has moved off of all WiFi and is solely on your carrier data network, then the two will continue to communicate via that means.
In that last configuration, your BB is communicating to your PC via the wired (or WiFi) network on which your laptop is located, and the BB is communicating via the carrier data network. Those two are then in turn connected via the Internet.
This is a setting you control, on the device. If you do not want this communication happening when the BB moves solely to the carrier data network, then simply shut the setting off on your device.
Hope that helps!

Z10 lost connection to mobile network

My Z10 worked fine for the past 2 years. Yesterday it received messages until 8:08 am, then lost connection to the network. It is a Verizon phone with Verizon SIM and Verizon support told me to go to a store to get a new SIM. That did not resolve the problem. The icon in the upper right now says "SIM activation in progress"...as it has for the past 12 hours. Clearly nothing is happening. When I check Settings, About, SIM, the Z10 reads the SIM but the SIM is not registering with the network.
One guy at the Verizon store had never used a Blackberry and was on Google looking for answers. He suggested it was becuse I went through airport security. Another said the phone had failed and he wanted to sell me an iPhone. I don't want an iPhone and I don't want to lose my unlimited data plan at Verizon (which terminates if I upgrade through Verizon).
I am not convinced it is a hardware problem but I don't have any way to test it and the Verizon guys are just guessing...and trying to sell me an iPhone.
I have not upgraded any SW or changed any settings recently. The phone has not been dropped or anywhere near water...it looks brand new. It just stopped working mid-morning.
How do I get my Z10 working again?
Thanks

Hello,
Given what you describe, you must also have rebooted the device...since the inserted battery blocks the ability to remove/insert the SIM card. So, that basic guidance has already been carried out.
Have you checked the Mobile Network Settings, just in case something was changed accidentally somehow?
Otherwise, what you need to do is escalate beyond those at VZW you are presently talking to...clearly they are not the experts you require. You likely will need to call them (from a landline, so you can do things they recommend) and escalate beyond their Level 1 support folks and get to someone who actually knows the platform and can also check deeper into the VZW network itself.
Good luck and let us know!

Connectivity with TMobile Network- 9110 Communicat...

I have an old Nokia 9110 which once l charged the batteries works. However when l did a network search it only recognised O2 and Vodaphone. Here is a challenge to all you boffins out there - why is this? Is their a fix?
If so how do l achieve connectivity?
Richard

I used to have one of these.
The Nokia 9110 only supports GSM 900mhz networks, not 1800/1900mhz.
Internet access is via dailup at 9600/14400bps (CSD/ISDN v110/v120 was added with the 9210) - check the internet dailup number with your network service provider.
9110's can have the memory corrupted if a reboot or power less occuring during file updates.
This is fixed by a format and restore from Backup.
Install a 'reboot' program if needed, otherwise you will end up removing the battery.
A common fault is the battery block falling off - so do not remove it unless it's essential.
9110 used it's own version of PC Suite.

Netgear router won't let me connect with a network my new roomates use

I have had this problem before connecting to wireless networks, although not all of them. I just moved in with a friend who gave me the network name and password. Although my powerbook G4 sees her network, it shows an error message when i try to connect with the password. She set up the Netgear (WGT624 v3) router using her DELL and everyone else in the house (using PC's) don't have this problem. I'm wondering if we need to go through what she has set up on her computer, because I must have tried everything on mine! Does anyone know how to solve this problem?

Hi tracie,
thats OK I know how hard wi-fi is to setup, I've spent many hours in the past trying to figure out how to set mine up! Its usually the simplest of things.
Your MAC address or Airport ID (as Apple call it) is a string of a series of 6 two digit numbers/letters separated by a colon e.g. 00:2b:35:18:af:32
This identifies your Airport card on a network & your address can be viewed in System Pref.s/Network, then from the drop down "Show" menu choose "Airport" & then click the Airport tab that appears in the row of buttons & you should see your Airport card's MAC address (Airport ID). But if you cant find that option don't worry about it.
While your in Network Sys Pref click show port config. & drag the Airport entry to the top of the list.
If you do try WEP again, go to router's
Wireless Settings > Wireless network
& insure the Mode is set to "g and b" just incase.
Then > Security Options & click WEP.
Then in > Security Encryption > Authentication type
set to Shared key
Also > Encryption Strength
set 128bit
After that go down to > Security Encryption (WEP) Key
in Passphrase enter your new password & click the Generate button on the right - this will bring up your HEX key in the checked "Key" box below.
write this new generated key down & click Apply & log out.
Now on your PB open the Airport network entry window, change top box from "WEP Password" to "WEP 40/128-bit HEX"
Then enter the generated key you wrote down into the box below, & click ok/join.
Keep 'em crossed & you "should" join.

Can't establish internet connection with NAT network in Oracle virtualbox

Hi all,
I am new to Oracle virtualbox. I have created a new virtual machine with Oracle linux 5.5 (64bit). I have enabled the NAT networking adaptor so as to access internet connection from the VM. But I am not able to do so.
Here are the network settings in the VM
1. Automatically obtain IP address settings with DHCP
2. Firewalls are disabled.
The 'eth0' device shows active status. The #ifconfig command lists "inet address" as 10.0.2.15.
Please let me know if any additional configuration is required for establishing the internet connection in the VM.

The NAT engine of Virtualbox automatically provides a router between the network interface of your host system and the virtual network interface of your guest OS and offers the same DNS servers to the guest that are configured on the host.
For more information how it works, see http://www.virtualbox.org/manual/ch06.html#network_nat.
The problem you are experiencing is most likely with the network configuration of your host system.

Issue with mobile network vs wifi

Hi all, after using wifi the iPad cannot connect to 3g. It says that server is not responding or that it cannot activate mobile networks (while the signal strength is full). So I need to restart ipad and then it's ok. Thanks in advance

Same problem here...more specifically out of nowhere my ipad 3 seems to be unable to activate cellular network. But the "wheel of death" will spin and spin for many minutes prior to alerting me of the connection issue.
My ipad 1 was problem-free and the 3 just seems so much slower, especially when connected to 3g/4g.

Issue with mobile network signal ("Searching")

I recently purchased 2 iPad from Singapore and upon retuning to Malaysia, i applied for 2 mobile broadband package from the same mobile provider.
Issue i am facing is, on one of the ipad, the mobile network signal bar displays "Searching" almost all the time; only a few times it displays strong signal with 3G icon then it drops to "Searching" again. I tried to swap the micro sim around between both ipad but no such issue on the 2nd ipad which is consistenly strong signal.
I even restored the ipad (factory shipped 3.2.2) but no success.
What should i do?

After further test, I noticed the unit can't find any mobile provider under Settings > Carrier when signal bar displays "Searching".
Enabling airplane mode does not help either; only workaround is to disable Cellular Data under Settings > Cellular Data then Enable it again.

No connection with mobile network
