[Q] GPRS connection but no GSM

Hey guys,
My phone stopped working about a week or so ago and I tried everything to fix it, nothing worked, stumbled upon this thread: http://forum.xda-developers.com/showthread.php?t=1045869
And decided to check if my IMEI was blocked (it was), I called Tesco Mobile, asked them to unblock it, which they did but I cannot make any texts or calls. I have tried:
-Reflashing radio
-Reflashing ROM
-Factory Reset
-Leaving battery out overnight, putting it in the next day
-Tried SIM in other phones - it works in other phones
-Reinstalled stock Sense ROM
The strange thing is, I can use the internet but cannot make texts/calls. Advanced info via *#*#4636#*#* shows:
IMEI: same as on phone
Phone Number: correct number listed
Current Network: Unknown
Singal Strength: 0
Location: LAC = unknown CID = unknown
Neighbouring CID = unknown
Roaming = Not roaming
GSM service: Disconnected
GPRS service: Connected <<< WHY IS THIS CONNECTED AND GSM ISN'T?!
Network type: unknown
Message waiting: false
Call redirect: false
Radio resets: 0
Data attempts: 0
Data successes: 0
If I try to change the network to anything other than GSM only then it just reverts back to GSM only. The SIM works in any other phone, my phone IS unlocked, was working perfectly prior to being IMEI blocked, so what appears to be the issue? I called up Tesco to confirm the bar is removed and they said it is, so, what gives?
EDIT: I can happily browse the internet while out and about - no wifi, definitely GPRS as I use it while I am away from my home wifi/any wifi I connect to. I am confused as to why I can use GPRS but cannot use GSM...

maybe bad sim?

SIM works in other phones and didn't have a problem with it previously... As in I can make calls and texts if I use other phones but only internet in the HTC Desire... :S

GT-N7105: Sim Card Not Detected

Hi,
I just was given a Note 2. The problem with it is that it doesn't detect the sim card (even though one is inserted). It's a GT-N7105 and apparently has been unlocked to work with T-mobile.
An IMEI number is listed when I go to about phone >status. Here is what it says on the "status" page
Network: Unknown
Signl strength: -105 dBm 4asu
Mobile Network type: Unknown
Service State: out of service
My phone number: unknown
What have I done is hard factory reset the device, rooted it, installed a new version of Bliss Rom but that hasn't fixed it. What should I do next?

CM12.1 can't connect to mobile network.

I just reflashed CM12.1 and have a BIG problem. I can't connect to the cell network.
On the SIM status page, this is what I see:
Network: unknown
Signal Strength: -75dBm 19asu
Mobile Network Type: Unknown
Service State: out of service
Roaming: not roaming
Mobile Network State: disconnected
My Phone Number: it is shown but i won't post here
IMEI: also shown but I won;t post here
IMEI SV: shown, but won't post here

Dude stop making new threads everytime you run into a issue, keep it in 1. It's annoying.......
Try another rom ...... see if they works, simple.

HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14 -> Voice Only, No Data

I just installed the HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14_AROMA-Installer.zip on my HTC Verizon M8. After doing so I can only get data via Wifi, it does not connect to 3g or 4g. I was wondering if this is a known issue if someone could direct me on what steps I should take to troubleshoot. I should mention that even though its a verizon phone I am using Smart talk.
Here are my current settings:
Preferred network Type: Global
CDMA Subscription: RUIM/SIM
Access Point Names : VZWINTERNET.
Network Operators : receive "Error while searching networks"
SIM status -> Cellular network state : disconnected

You used this version? http://forum.xda-developers.com/verizon-htc-one-m8/development/rom-vzw-stock-gpe-5-1-lmy47o-h9-t3212413
Did you do as the thread states:
[*] If you have issues with 3g/LTE data hand off, do a full RUU and do a factory reset with the stock recovery. Alternatively just flash the stock recovery and do a factory reset. Theory is the stock recovery rebuilds NV data. Getting a new SIM card has also been reported to work. Calling customer service and asking them to reset your connection has also been reported to help.

I'm having similar issues but I'm using page plus(Verizon network with Verizon m8 and only text and calls work but no data. Also using Verizon APN any suggestions

My phone doesn't detect SIM*card with lineage OS

Hi,
I recently bought a second hand smartphone Galaxy S4 GT-9505 which according to IMEI info was first delivered on 2013 r. and uses a Qualcom Snapdragon 600 APQ 8064T chipset and is powered by a 4.2 Jelly Bean android version. I use a French Orange SIM card that works normally on other phones.
I installed the recommended version of LineageOS for this device.
The installation went smoothly and the system boots normally. Nevertheless, after booting I can see a barred SIM card icon on top of the screen.
In the Mobile network settings only one entry is available, i. e. :
- Data roaming is greyed and not accessible
- Preferred Network type is greyed and not accessible
- Connected line identification is accessible
- Access Point Names is greyed and not accessible
- Network Operators is greyed and not accessible
Finding a tuto dealing with this kind of issue, I phoned *#*#4636#*#* . Then I could go to Phone info menu and there I could see this :
IMEI : my imei
Phone number : unknown
Current Network :
Signal strenght :
Voice Service:
Data Service: Disconnected
Voice Network Type: Unknown
Data Network Type: Unknown
Voice Call Status:
Roaming:
Set Preferred Network Type: here is a dropdown list. According to the tuto I tried every value but all of them failed to revive anything.
Is this a known issue and what can I do ?

Same can't find any info. I am using a oneplus T6
