[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...

No signal/voice/data - Restricted access changed. Voice service is blocked

Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.

Maybe the IMEI is banned for some reason?
Never heard of this issue until now
Have you tried to flash a firmware that aren't from any carrier?

Yes I did, flashed the USA unbranded kitkat rom.
Just got the chance to test with two sim cards from different carriers:
Carrier #1: Registered on network, no data traffic, voice call drops just after trying to call, signal ok
Carrier #2: Registered on network, data traffic seems ok but can't navigate, shows H+ and proper APN and traffic arrows activity but when you try a call it says "Mobile Network Not Available"
Can't send SMS, they stick with a "Sending" status and wont get past it.
This phone was purchased unlocked without a contract, can't see how the IMEI could be banned, plus we do not have regularization for IMEI ban in my country, it's currently a mess.
On a side note it does not detect the sim's phone number which it does on any other phone.
Maybe it's some hardware related issue?

Well that's interesting
My phone can't detect my Sim's phone number either (though i don't know If it is only for me)
Have you tried to flash a ROM? (from XDA)

The sim number information depends on the sim itself, most carriers register this information within the simcard so when you go to status you may retrieve your own phone number but I have seen sim cards without this info. The sim cards I tested do have this information and were available on a Galaxy S5 and Xperia Z1 but this E1 fails to read this information which kinda indicates a problem. I don't remember the codes for debugging the sim and network info or I'd give that a shoot.
I will try a custom rom, maybe a different kernel and see if the behavior changes any bit.
I am bidding on a Z1 Compact for this friend, should be a proper replacement and a hell of an upgrade, just concerned about E1's loudness which is certainly superior.

Interesting, I also get this if I don't reboot my phone after like 5 days.

SM-G973W Not Registered On Network

I just bought a used phone, I put my sim card in and it says "not registered on network". I tried my friends sim (confirmed working) and I get the same thing. I checked the IMEI and it's not blacklisted or anything, I'm really confused. I'm in Canada and it has Bell apps installed if that matters. Any help would be appreciated.
I've tried to manually select the network. I'm on public mobile, I see the option to select it but it doesn't work
I've also reset it twice
