Lost signal - Samsung Galaxy Note 8 Questions and Answers

I've flashed my note onto a custom rom and I've lost my gsm network, btw my phone shows the provider's name but when I try to dial any number it shows "not registered on network"
Do you know what is the problem?

No connection - why??

M700/Trinity with 6.1 Rom and latest Radio rom. Virgin sim card from another working phone used. Shows UMTS T-Mobile UK connection and 3g icon but when I try to dial out, it justs drops the connection. If I try calling the phone I get the message "Calls are not currently being connected to this number". Oh, and the IMEI is not blocked (I checked). any clues???

[Q] unlocked sgs but now shows no signal?

hi had a search around but unable to find anyone who has had the same issue
unlocked sgs from UK t mobile to use vodafone sim.
all was ok till i changed the setting to stop 3g to improve battery life, sgs went to no phone signal (blue circle with line through it on top bar). put 3g useage back on but still no signal
had a look at my phone/status:
network = vodafone uk
service state = out of service
mobile network state = disconnected
if i set network automatically it says 'registered on network'
if i select vodafone from list i get 'your sim card does not allow connection to this network'
i have hard reset the phone, locked it and unlocked again, but still the same
also tried with o2 sim and get the same problem
== t-mobile sim still works==
is there a solution out there?
Try to manually create another APN
EDIT: my bad...you meant no phone signal. I have no clue but hope that you'll get the help that you need.
what needs to be entered in the fields?
i've had this happen on two phones..........one was due to me messing up the nv_data files. the other was fixed by reflashing.
take your pick
i haven't had the phone flashed
i only used ADB to get the Network Control Key which i then use to unlock the phone
can you suggest the next step for me
i assume the professional unlockers use a flashing method, should i get it unlocked by one of them?
its possible the imei has been blocked
if blocked tmobile customer service said that i should hear 3 beeps when i try to make a call, but i get a message that 'not registered on the network'
could it still be blocked even though i do not get the 3 beeps?
if it is not blocked is there anyway i can get this working on a vodafone sim?

[Q] My phone is unlocked, so why wont my T-Mobile SIM work

I entered *#7465625# and it says
Network Lock OFF
Network Subset Lock OFF
SP Lock OFF
CP Lock OFF
Yet when I put my T-Mobile SIM in, it says EMERGENCY CALLS ONLY
When I got to SETTINGS, NETWORKS, MOBILE NETWORKS, NETWORK OPERATORS
it searches
Then when I choose T-Mobile or T-Mobile Orange
It says "Unable to register on network"
And then immediately says "connected to network"
Then back on the desktop it shows "emergency calls only"
Can anyone help please?
can you check for your IMEI number *#06#
How does that number help?
I was going to put it on here, but a quick Google came up with:
"i would never give my imei no. out to anyone the reason is that the imei is the identification of the phone a bit like a chassis no. on a car now if you give your imei no. out then there could be a chance your phone can be cloned i.e copied ! so if someone else has the same phone thats been stolen the imei no. can be transferred to the stolen phone its obviously highly illegal but there are some dodgy people out there who can do this"
So I'm hesitant to give it out on here
Do you have any idea what can be done to sort my phone?
Thanks

[Q] Network Issues

Hi guys,
I'm having network connection problems I recently purchased my RAZR I, was informed it was unlocked,
however when I insert my 3 sim, I get the message " Cannot connect to network at this time, please try again later" !
The phone doesn't display any sim error messages, I've purchased a 16 digit unlock code, in case its locked,
but am unable to enter it into the phone as no error screens pop up, I've tried android codes which are
supposed to "call" the "enter code"scene, but without success.
I can't find a working code for the "engineer mode" either....
I've changed radio mode to "gsm only" (I'm in the UK)...
I've rebooted, factory reset....etc etc
Phone info screen states... Network unconnected
GPRS. off
I'm at a loss... How do I remove the "little red triangle", emergency calls only & connect to a network so I can use the phone.

Which software is installed?
Which provider do you try to use?
Is the sim card working in an other phone?
If you manually search for a network, do you get any choice?
Phone is running stock ROM ... Jelly bean.
I'm trying to use my Three Network sim which works fine in other phones.
I've manually searched networks... Results show 3, Vodophone, o2 & Orange... Selecting 3 brings up same "cannot connect at this time...." message.
I've checked APN settings, they're as they should be !
Thanks for quick response...

Which exact software is running? Please the full image string.
That would show for which country/continent the phone is setup. Maybe you also just need to call Three Network and ask if they see some error on their side.
Stats are as follows...
System version
91.2.29001.XT890.Retail.in.GB
Android
4.1.2
Kernel version
3.0.34-g261995f
[email protected]))
Build number
9.8.21-50_SMI-29.1359955748
As the phone won't register on the network, Three are unable to test the connection ! Plus my sim works in all my other phones.
The RAZR I is reading the sim as my contacts import to the phone, so I don't think the sim jacket is at fault either....
Hope this helps...

Oh ! I've also checked the IMEI number online & as far as I can tell its not blocked...
Come on guys any ideas.....

No idea now. It could be a broken phone or a broken sim. Maybe one metal contact on the SIM is broken, or something like that.
I've been in touch with Motorola, there answer is a factory reset.... I've tried a few sims and all are recognised ( the associated APN loads every time...) but still no network connection. I've also checked the antenna connections to ensure contact is being made....
Could this be a software issue? The phone is rooted, can I use ADB to alter IMEI ?
Thanks in advance...
