Semi-incompatible sim with new ROMs (can't send texts)...

For background, my device is a c500 (typhoon) and I've tried various roms (but I'm using the 6.1 one atm). I didn't have this problem with the stock ROM.
I find that, although the phone works and I can recieve text messages, I can't send them because the "text message service center" field is empty and if I enter anything in the box, it clears as soon as I leave the screen.
Also, trying to use the SIM manager (for contacts etc) returns the message "invalid or missing sim".
To me, this seems to be a semi-incompatible sim card. I've seen other phones with the same issue (eg here) so I don't think it's a specific phone/ROM issue. I've tried SDKCerts.cab and using a cab to install the network settings, neither worked.
Has anyone seen/fixed this before? Thanks.

have you tried another sim?
not sure about your operator but mine always send me a new sim if i so request for free

Hmm. I tried an O2 sim - works fine. Maybe it's because my sim is 3G (and the phone isn't)?

Here's a similar thread on modaco that comes to the same conclusion. If anyone else has the same problem, this is probably the solution.

just trying my luck, is there another solution to this issue yet, orange uk wont send me a 2g sim for anything so im stuck

UPDATE:
For information orange wont send me a 3g sim as the handset i should have is a 3g phone so they dont want to know
unfortunately I cant keep the phone as its no good to me

[Q] Problem : No call, no SMS, but 3G ok

Hello, I have a big problem with my Nexus S Eur (I9023 SLCD)
I bought it used but almost new, and no bill…
The phone, not modified, worked fine for 3 months. (2.3.4 GRJ22)
But one day I could no longer use the calls and SMS, while the Internet connection (3G) worked fine.
The majority of other sim cards are not properly recognized, but mine yes, it recognize the PIN code, the network (Numericable, a French MVNO), and correctly read the APNs. I can go on the net with data connection, but no call, no sms… (No MMS in the subscription I chose)
I tried to restore it with ODIN like I read here, it worked fine, but same problem.
I tried Custom ROM, custom Kernels, I tried ALL the radios of the I9023, no change…
When I call, no error it just hangs up the phone.
SMS, it says sms was not sent
The only one error I can read is, when I want to consult the call forwarding settings : “Network or SIM card error”
Any idea?
If the phone is a stolen one, and if the IMEI is blacklisted (3 months after?!?), is it normal that I still use the 3G connection?
The simcard work fine in my old phone
Thanks !
PS : sorry for my english, I do the best I can

No idea?
Maybe Hardware problem?

is the phone rooted?
try the *#*#3646#*#* to select your correct baseband settings.

When the problem started, the phone was rooted
After, I tried rooted and unrooted
With the 4636 I can access to the list of the baseband settings (now GSM/CDMA Auto (PRL) ), but if I change it (GSM only for exemple), it is not saved.... It doen't say anything, but if i quit the 4636 screen and return to it, it is GSM/CDMA Auto again....

Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.

Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.
Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!

Same here
I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.

Lineage OS 7.1.1: Unable to send SMS messages

Hello all,
I flashed my girlfriend's Sprint S5 with Lineage OS recently without a hitch, all services working perfectly. We ended up traveling, so she went to Sprint to set up a temporary international roaming plan. Everything was completely as expected abroad. When we got back, her phone would not send SMS messages.
We tried the usual airplane mode and such, and to no avail. Assuming something was wrong with the network configuration from travelling, we reset network settings. Didn't work. I then decided to just do a full wipe and re-flash of Lineage OS. Still doesn't work. I then resorted to going back to the stock TouchWiz ROM from Sprint. At that point, under the stock ROM, SMS were sending. Out of curiosity, we flashed back Lineage OS, and SMS will again not send. We noticed that if the SIM card is removed, SMS will send, but the phone would not be able to access 4G LTE. We also confirmed with Sprint that there are no restrictions on the account.
What could be causing this to occur only on custom Roms? Do we need to do a PRL update? If so, how does that work on stock Android?
Thanks in advance!

S5 sprint No outbound sms
I've had this problem for weeks....So far the only solution is using Google voice app....

I'm using LOS 7.1.1 20170207 kltespr nightly, LTE SMS can only receive, sending doesn't work. Only 3G SMS works.
Things I noticed:
Settings -> About Phone -> Status -> IMEI Information. When on 3G, all information is displayed here, when on LTE, only IMEI and IMEI SV is displayed, there's no PRL/MIN/MEID/ICCID anywhere, not even disabled or greyed out, just hidden completely.
ICCID also shows DUMMY_NV_ICC_SERIAL instead of the actual ICCID.

Same experience for me, I've been trying to find a workaround for over a month with no success. Alternative text messaging apps seem to work, but I don't trust 3rd parties with my SMS.

Unable to send SMS
Mike.
Which third party SMS app are you getting to work? Besides Google voice I have had no luck with any third party app?

I'm having the same issue. I'm on Resurrection ROM which is based on Lineage. Since update I can't send SMS at all other than via Google Voice. I can receive SMS and I can send/receive MMS.
I did find that if I change to 3g only for my network settings, I can send SMS. But then of course I don't get LTE data speeds for everything else. So the issue for me at least is tied specifically to LTE. Wondering if there is an APN or other setting I can change that would fix this but so far no luck finding anything.

Bug reported since 01/28
https://jira.lineageos.org/browse/BUGBASH-37

I've run into the same problem or similar. If I set my preferred network type to GLOBAL then I can send and receive SMS/MMS messages but I'm forced to either Roaming LTE or 3G. It's often stuck in 3G after a drive for any distance. If I force it to LTE, then SMS/MMS stops working and I can't place or receive calls either but the network will show up as LTE and Sprint.
To get there from Settings Home -> More (under Wireless and Networks) -> Cellular networks -> Preferred network type -> Choose Global.
Sometimes I can force it back to LTE but roaming if I switch temporarily to LTE then once it connects switch back to Global. Occasionally I have to put it in airplane mode to get the radios to reset and connect but some combo of switching network type and ending up in global and switching into and back from airplane will do the trick.
YMMV of course.

one way I fix it temporarily is to:
cell networks - carrier settings, let it crash
go in again and let it find your carrier
once connected, make a phone call at least to get it ringing
I can then make sms mms.
it's a rediculous work around but it works for me every time

SMS Sending Problem with Lineage 14.1 (31.07.2017)
Heyy
I'm not able to send sms from SIM 1 but can send sms from SIM 2 in Lenovo A6020a46 (2GB) on Lineage 14.1 (31.07.2017).
The same SIM is working good in another roms and Calling + Internet are working properly.
After dialing *#*#4636#*#* in Phone Information - SMSC Refresh then it appeared "Phone no.", 456 and I pressed Update.
But there was no process for saving or updating. Then I reentered in Phone Information but SMSC Shows blank.
What to do??? anybody help in this matter will be immensely appreciated.

I made this file using Odin with the steps from here. I flashed the file, set the connection to LTE aand it worked. https://forum.xda-developers.com/showpost.php?p=71582847&postcount=5908

To fix this issue with having LTE signal and sending SMS at the same time you have to open EnginneringMode app (or *#*#3646663#*#*) and check 'Sms over Sgs support' in Misc Feature Config tab.

Doesn't work because nothing comes up entering the code. Any idea?

If that code doesn't work for you, try to find an app called Engineering Mode MTK. Unfortunately I cannot attach any screenshots yet (I got less than 10 posts).

fix
there is an option in network settings (enhanced 4G LTE mode for comunications etc) i disabled that option and messaging works fine now. before unchecking this option i could only send sms only with phone on 3g mode, now it works fine. i think this option is for hd voice calls via 4g lte.

I see this is an old problem and I´m having the same problem. I can receive SMS, but I can´t send.
But to add to that, I couldn´t connect at all with my previous carrier and changed carrier after which I can use data, call and send SMS. I still can´t receive SMS.

SM-N9860 - "Not registered on Network" error suddenly in the UK

Hey guys, really hoping someone is able to help me.
Back in September 2020 I purchased the SM-N9860 variant from T-Dimension for use in the UK on EE's network. Everything has been running smoothly since day one, up until yesterday (31st May) where the phone would constantly struggle for signal, flip flopping between "No service" or extremely slow 4g. If I try to make a call I get the "Not registered on Network" error message.
Since then I have done everything I can think of:
- Restarted the phone several times
- Switched Airplane mode on/off
- Manually selected my carrier
- Reset network settings
- Tried my sim in another phone (which worked fine), and tried a different sim in my Note 20 (exhibited the same behaviour of "No service")
- Checked IMEI but it's not been blacklisted
- Tried my sim in the SIM2 slot
- Full factory reset
but none of them made a difference.
Tonight I decided to try and flash different firmware to see if that might have any effect; both TGY and BRI firmwares were flashed successfully with Odin but neither have solved the problem. I'm now at the point where in my home I can see the 4g symbol appear above the network status for 30s - 1min but it never actually loads any data, before returning to "No service". Compared to my fiancee's S10+ which is also on the EE network and easily hits 20Mbps without worry in the exact same room.
Does anyone have any suggestions of what to try next? Has anyone else encountered this?
Thanks,
RBrNx

I've spent some more time investigating this and I am 99% sure it's an issue with the device.
Below you can see a screen recording of the issue that I made this morning while I was out a walk, you can see it goes from having signal but no internet ("Emergency calls only"), to "No service", then to 4g but I wasn't able to even load a website, before it moved back to "No service".
I've also attached two screenshots from the NetMonster app, one is from my Note 20 and the other is from my fiancee's S10+. Both were side by side when the screenshots were taken - mine has no service and her's has 4g.
I've since tried a number of other SIM cards in my phone, including another EE SIM and a Three SIM - both work immediately in the S10+, but neither are able to register when put into the Note 20.
I tried to contact Samsung Support but they were next to useless. The UK support team told me I'd need to contact Hong Kong support "as they have full access and information", but all the HK support could do was tell me to visit the HK Support Center...
I'd love to be able to fix this issue but I'm not sure what else to try
EDIT:
Some more information that I forgot to add - When I am out of the house I can occasionally receive calls/texts or use the internet, so I know for sure that they are all working (i.e EE haven't blocked my account) but most of the time I am stuck with "Not registered on network"
I'm wondering if it's an issue with the antennas, it's almost as if they are somehow weaker or less receptive than they were a few days ago

Does it behave this way when in safe mode ? How about in 3G mode? If it's hardware then Samsung doesn't recognize devices that are from other regions in relation to warranty work. You'll have to test the after sales support of T Dimensions now. Failing that sell it as is on eBay for parts or try and trade it for another device.

I'm using the same device on Vodafone UK and no issues here at all

I'm using an N9860 HK model, also from T-dimension, with EE since last autumn. I have not had any such problems with mine.
I haven't flashed or rooted the phone, but I have tinkered in the service menus in order to gain 5G service and possibly other service improvements.

Yeah, same for me. Changed the 5g whitelist settings but no root.
