Hello all,
I have Xiaomi Redmi Note 3 pro and after a drop, I cannot get any cell signal to the phone, it states "No Service" on both sims.
Wifi and everything else is working without any problem. The phone can identify whether sim phone is inserted or not, it just seems that its impossible to enable radio. I tried to reboot phone, turn-on off airplane mode, reset to factory default but no change.
I opened the back lid and all connections are in place, no loose parts are visible. Removed the antenna part, re-seated it and still its not working.
Below you can see all details on the symptoms.
- Settings / About the phone / Status / SIM Status:
Netowrk: Unknown
Signal Strength :0
Cellular network type: Unknown
Service State: Radio off
Roaming :not roaming
Cellular Network state: Disconnected
- Settings / About the phone / Status /Status -> IMEI Information shows MEID, IMEI for both slots, but IMEI SV is 00 regardless the presence of sim card in the slots.
Settings / About the phone and pulse several times on internal memory I go to the Testing menu and then I can see:
- Phone information 1
- IMEI is populated ok
- Signal strength 0dBm, 99asu
- Location: LAC = unknown, CID=unknown
- DcRtInfo : mTime=9223372036854775807
mDCPowerState=2147483647
- Current network: off
- GSM service: Radio Off
- GPRS service: disconnected
- Network type: unknown
- There turn on radio, select the type of network do not work whatever I choose.
Do you know how I can repair this situation? Is there any other lower level tool that I can use to force enable the radio or to further debug the issue?
thank you

Hi, have you solved the issue? I have same issue, need solution!
Unfortunately not, I shipped the phone back to the store I bought it and they sent it to factory where they confirmed an issue with the motherboard that was caused by the drop. They asked for $125 to repair it - I dont think its worth it since you can find this new for as low as almost $150

Oh...
Yeah you're right. Many people are getting the same problem so i don't think everyone has dropped their phone and have motherboard problem. It's just Xiaomi wants to fix the phone by easy way and earn something.

Hi guy's, have a UK SGS2. It's rooted and running Criskelo ICS rom. I've recently been in Brazil for 6 months, my phone worked fine over there. I've come back to the UK and got a standard Vodafone PAYG sim card. When I try and use it the phone says "not registered on network"
The sim card itself is fine as it works in my old mans SGS2.
I have wiped the phone and installed the standard software and it's still the same.
Anyone got any ideas what could be up?
The phone could be network locked (sim lock)
Sent from my GT-I9300 using xda premium
That's what the guy on Vodafone web chat suggested.
How and why would it get network blocked?
The phone was originally on the 3 network. I bought it 2nd hand about 1.5 years ago and it's been fine on T-mobile ever since.
If it is sim locked, is there a way to unlock it?
You can unlock with:
https://play.google.com/store/apps/...sImV1LmNoYWluZmlyZS5zZ3Myc2ltdW5sb2NrY29kZSJd
It's free on google play.
I don't think it's sim locked, I can put any chip in it. It doesn't ask me for an unlock code.
I have run the sim unlock tool. The code it came up with is 00000000
When you go into the network settings, it shows all the service providers. every provider I click on says "can't register on the network"
I'm wondering if i've had some sort of network update in Brazil that's screwed it up?

I'm sure its something to do with being abroad as i've read about someone that had the same issue when they went from China to Denmark.
If I go to settings - phone it says...
Network - Unknown
Signal Strength - 103 dBm 5 asu
Mobile Network Type - HSDPA:9
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
My Phone Number - Unknown
IMEI - the correct number, I checked
The fault isn't with the sim card itself, I can use it in other phones and I can save a contact to it in this phone.
I'm wondering if some of those network settings I had from the Brazilian phone company's have messed something up.

1. Disable Mobile data, then wait for 3-5 minutes
2. Enter Service mode, then change network to WCDMA only, repeat it like 2 times.
Done.
Correctly good luck...

my problem is described here -Can others be so kind as to verify if they are also having an issue with receiving voice calls or SMS while their phones are using the 2G network for data access. (3G and wifi either unavailable or turned off.)
We have this issue with Orange and I have tested it on one Sunrise iphone4 and we had the same issue. Which is not surprising since Orange and Sunrise are operated by the same staff. It does work correctly over Swisscom.
I raised this case with Orange over one month ago and they still have given me no concrete feedback as to why their network behaves like this.
(FYI this is a network issue and not related to any phone configuration).
Feel free to harass Orange about this. It might get them to pull their fingers out a bit. When I raised the case it took me about 10 calls to their support plus 2 visits to Orange shops to finally get a technician who was capable of understanding this simple but critical issue.
EXACT STEPS LEADING TO PROBLEM:
1. Force phone to use GSM (2G) mode only or be in an area with no 3G coverage, or if your phone chooses to use the 2G network
2. Disable switching to wifi:
3. Connect to 2G packet data, download email or download webpages: Status Bar-> spinning wheel
4. While packet data is connecting, using another phone place a call to your phone
5. After packet data has connected, using another phone place a call to your Phone
EXPECTED OUTCOME:
You expect the packet data connection to either DROP or be SUSPENDED (depending
on network capabilities) and for the phone to ring indicating an incoming call or SMS.
ACTUAL OUTCOME:
The packet data connection persists and remains active; the phone does not ring
and the call is handled by the network as if the phone was unreachable (for most
users this means forwarding to voicemail).
REPRODUCIBILITY:
always; no exceptions.
This has been tested extensively on the Orange network by me and many other users.
Tested devices which all show the same issue, iPhone4, iPhone3GS, Iphone 3G, several Android models.
Hello I have a really annoying but strange issue I cant make phone calls or send and receive text messages but I can browse the internet.
I have a Samsung Galaxy S3 which im sure is sim unlocked but im not 100% sure. It has been working ok up until recently something has changed but Ill be dammed if I know.
I am using GiffGaff and reported my SIM lost so they send me a new one with the same number on it but this did not work.
Im running the stock ROM ..I tried to re-root the phone but this did not work.
I have done a factory reset this has not worked.
If I take the sim out of the S3 and put in into either my old HTC Desire or HTC Desire S it works fine i.e I can make and recieve phone calls.
But soon as I put it back in the S3 it says "Unable to regsiter on network" so it HAS to be the S3 but im sure it is sim unlocked! ive previosuly tried Vodoo unlocker and it said sim lock status inactive could it be wrong?
I tried similar to this: (But when I got to network lock it says on my S3 (MENU NOT EXIST PRESS BACK KEY Current command is 186) what does this mean???
==============================================================================
"Put in a different SIM card to the one you use with your carrier.
Switch the device off and on again with the SIM card in place.
Open your dial pad and then type in *#197328640#.
Go to Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > and wait 30 seconds or so.
Then hit Menus and choose Back. You should now see Network Lock. Then choose [4] NW Lock NV Data INITIALLIZ."

Please can someone help !!
Does your IMEI start with 00 now?

No it starts 35 ?
so it matches with the one under the battery?
If the SIM works in other phones then the S3 is the problem, try a SIM from another network in the S3 to see if that connects.
If it doesn't then I'd guess the phone IMEI has either been blocked or is locked to another network (but wou would see a network lock message in that case). You say you can still access data - are you sure that is with wifi turned off? If it is unable to register on the network then gprs won't work either.
I suppose it might be possible for a part of the radio modem to corrupt, or a hardware fault. Try flashing a full stock ROM including a radio, with a full wipe before trying the SIM again.

For the post above this the SIM on the phone and battery are the same apart from at the end of the number there is a " / follow by a number" this is differant.
On my mobile the IMEI ends in 6785701 /04
on the battery the IMEI ends in 678570 /1
Not sure if thats relevant?
I am not conncencted by Wifi soon as i hit "Mobile Data" GPRS is enabled and data is enabled. Ok ill try what you said.

The bit after / is not relevant on the IMEI .
Have you actually entered the GiffGaff APN settings .
Or are you running on O2/ Tesco settings and not Giffgaffs .
Backup data and factory reset first .
Then update firmware .

I have double checked thatmy APN settings are correct as used this gudie: http://community.giffgaff.com/t5/Le...tings-for-Samsung-Galaxy-S3-Also/td-p/4491856
I know they must be working as soon as I enable the giff gaff APN I get GPRS data just i still cant make phone calls.
I have already tried a factory reset this didnt make any differance. When I try to force and upgrade on the S3 it says "Your device has been modified sotware updates are not avialble"
I have ordered a free micro sim from Three (thats the network i know my S3 was originaly supplied by) once i have triem them ill update.
I have run a CHECK MEND Report it is showing as this:
Ever blocked CheckMEND has a record of this item having been blocked by a cell phone network
Currently blocked CheckMEND has a record that this item is currently blocked by one or more cell phone networks
Lost CheckMEND has no record that this item is currently reported as lost
Stolen CheckMEND has no record that this item is currently reported as stolen
Insurance claim CheckMEND has no record that this item has been subject to an insurance claim
Possible counterfeit CheckMEND has no records that this identifier has been used in counterfeit products
Previous use CheckMEND has no records indicating this is a used item.
Possible clone CheckMEND has no records that this identifier has been used in cloned products
Recycled CheckMEND has no records that this item has been recycled or refurbished
Contract status CheckMEND has no records relating to this items network contract status
Warranty CheckMEND has no records that this item has been subject to a warranty claim
Finance CheckMEND has no records that this item is subject to a current finance agreement
So looks like its blocked ill try another sim on it.. hmm
Its the IMEI that gets blocked not the sim .But worth trying another sim anyway .

First of all this is not my phone nor my fault.
So It started when my mom's phone screen broken and got fixed in a local shop, after the phone screen was fixed the phone was not able to connect to a network "Not Connected To A Network".
I have tried
- Searching for Networks
- Changing SIM slot
- Getting a new SIM
- Resting the phone
- Device initialization (with Smart Switch)
IMEIs are correct
and I got no back up for the EFS folder nor did the shop back them up
Hi
I bought a second hand Sony Xperia M4 Aqua E2303 and I'm having trouble making and receiving calls. I'm hoping someone can shed some light on what may be the problem.
The phone recognises each of the different sims ive tried (showing the network name in the top info bar) but none of them are able to make calls, the call just times out and ends without any dial tones.
The signal strength is always very low for each network so I wondered if there was a hardware issue with the antenna. While searching for some information I ended up on the Service Menu > Sim Lock screen. As each of the sims I've tried have been recognised, I assumed the phone was unlocked. However, the SIM Lock screen details are confusing me. This is what is displayed -
[X] Network: 0
[X] Network Subset: 0
[X] Service provider: 0
[X] Corporate: 0
]X] SIM: 0
From what I've read so far, when an "X" is next to either Network or Service provider, along with a number, the phone is locked with a certain amount of tries left to unlock it with a network unlock code. If Network or Service provider is marked with an "X" and has a "0" after it, the phone is hardlocked to a network.
What is confusing me is that every sim I've tried in the phone has not asked for any network codes, so again I am assuming the phone is already unlocked to all networks, but why is every line of the above info marked with an "X" and a "0"? Every screenshot I've seen of the SIM lock screen only shows an "X" next to Network, but why does every line of my phone show an "X"?
Thanks for any info you can provide.
It could be that the phone u bought was a defective one. But I will try to do some more research into that issue as it a unique issue and I never experienced this.
Update:- It might be locked to a carrier of some sort or it just could be some antenna cable inside the smartphone just came plugged off or its just some software bug.
Also have you tried resetting your phone like wiping the data completely from your Xperia? If not try that or you have reset it but its still showing that issue, well I cant help much after because I have ran out of what could go wrong on your device.
