Hello
i changed phone operator two days ago, i put the new sim into my phone but it do not recognize the sim card. i went into network settings but some options like "access point name" is disabled ( i guess because it do not read the sim..). even if I try to connect to wifi..it does not work..it wont evene scan for network.
It was working just fine before i changed the sim...i also tried a factory reset....but nothing...i put different sims but it just wont recognize ( the new sim works fine on any other phone...)
Any suggestions??
is it something can be fixed via software?
Thanks

Got my brand new HTC Touch Cruise the other week and it was working great. I then decided to try and Geotag my photos which apparently is as simple as changing a registery value. So off I go and download the trial of Resco Explorer 2007 and reg editor from their website and change HKLM\Software\HTC\Camera\P9 »Enable« to 1
Soft reset the phone and then the phone no longer connects to the network.
(The geotagging feature of the camera worked fine too.....)
I uninstalled the tools, did a hard reset and reloaded the original ROM to no avail - the phone still refuses to connect to the network (Telstra NextG - Australia) which it was working fine with before. I have also noticed that when there is no Sim in the phone the IMEI does not agree with the one on the back and when the Sim is in it says the IMEI is "Not Support"
Any help would be appreciated, I'm missing my new toy already!
Do a Hard reset and your problems should be gone. Easiest way is "Settings > System > Clear Storage > 1234". Remember to sync your contacts before you do it and good luck
I'd already tried a hard reset and loading the latest ROM (Which was the same as the one it shipped with) but that did not work.
Just tried doing it again the way you suggested and it's still broken.
Also on further inspection my IMEI when it doesn't have a SIM in to is almost the same as the one of the back but just has an extra 01 on the end. It still says "Not support" when I have the SIM in it though....
All sorted out.... It seems it was an issue with Telstra(They said they had a brief outage, and for some reason my SIM didn't reconnect to the network until they gave it a "Kick"), not the phone that just happened at the same time as I was editing the registery. Talk about bad luck......

Yes so next time your Polaris not working so blame always your operator if the device dont connect, The imei cant NEVER chance with a registry chance what ever you do with the device the imei never changes, with that numbers you cant mess with
you said the imei changed when you have the sim card inside and evidently you couldn't connect to the network because of that... so deosn't that implys there's a 'possibility' that bypass the hardware imei by doing something to the sim? we might be on to something here guys..
So got this shiny new phone and decide to root it for adblock etc.
The root went fine, I used the Xperia-L root zip not the chop--- something. So a while after that, maybe a day or two suddenly I get a No Service.
I went into Settings-Mobile Networks and try to choose the network manually, I couldn't, I can move through Auto and Manual but when I select Manual it always goes back to Automatic. Can you guys confirm that that settings doesn't work? Can you choose Manual instead of Automatic?
Then the phone scanned for available networks and it found my home network relatively easy...
NOW selecting my home network gives me the error "Could not join network right now. Please try again later"(or something like that). A minute after that a toast message pops up "Registered on Network" but I still get no service...
Anyone have any idea? I thought Sony phones are root friendly with them sponsoring CM and all....
I have tried everything. Unlock, relock bootloader, restored TA...flashed stock firmware....taking the sim card out while power is still on and inserting it again.....
So frustrating, thanks for any insight....:fingers-crossed:
It happened with me..
What I did is,
Switched off the phone
Removed SIM card
Restarted phone
Again switch it off
Inserted the SIM card
Restarted the phone..
It worked!
Heres whats going on
I have reset the N5, and flashed the July MM image. Everything flashed fine.
I insert SIM before booting, Android doesnt see SIM... so i pulled out the SIM and reinsert while on, and it sees it.
The Signal goes into an empty triangle... It says you have voicemail. And nothing else happens.
No data, no service. *#*#4636#*#* shows the right selection, it gives me the option to turn on the radio, but if i click it, nothing ever happens.
Under phone info, it sees my phone number, the IMEI is fine, and its not blacklisted when i check multiple carrier's websites.
I just cant seem to figure out why it wont just acquire service signal even when APN settings are right.
Anyone got any tips, tricks or solutions to this?
Possibly damaged sim card or sim card reader?

dont think so, i think its software maybe.... When i do *#*#4636#*#* it will show my phone number on the top... if i remove SIM, the number becomes "unknown"... so i dunno
If it happens with all SIM cards, it could be a damaged sim reader as different areas of the SIM card contains different information? Not sure.
I have similar problem with MOB30P on T-Mobile network. The 4G LTE would work just fine (I can browse web etc), but the voice is where it is failing hard. I would have dropped calls along with calls not coming through (both calling out and receiving calls).
I downgraded to MOB30M and everything appears to working fine now. I have not opened any bug against Android yet, because I am not sure if I am the only one experiencing this problem.
Hi, I was googling for a problem like your one. My N5 does not recognise the sim at boot, but only if it is "hot". If I put it in the fridge for ten minutes and then reboot, all works fine until the next shutdown. I'm sure it's an hardware problem (already tried different sim) so I disassembled all the phone, and it looks perfect. With some cleaner for electrical contacts it can survive for some days, and then starts again. So sad, I don't want to change phone just for this stupid problem XD
I'm getting exact same issue with my Nexus 5 since CM13 0803 update, which brings MOB30Y to my phone I believe.
At first my phone could still recognize my carrier (China Unicom), but there is no signal.
Then I flash radio image from MOB30Y and the phone now cannot find SIM card completely.
Even reflashing factory image doesn't help.
I'm now trying to reflashing MOB30P to see if it helps.
Update to latest August security update radio and bootloader
it is my uncle's phone
SM-G920F Galaxy S6 (G20FXXU5DQA2)
flashed back to stock and everything is 100% stock but the mobile networks in settings is missing and the sim cards wont work, it detects them being inserted but doesnt seem to connect.
Please help, couldn't find anything
Messing around with mobile data gives "insert sim card"
tried to factory reset from recovery, clearing the cache and reset from the Smart Switch desktop software.
Could possibly be an issue with the sim card slot, does the phone show a valid imei number?

100% hw, faulty SIM reader, cold solder, or something else on motherboard.
Try to ask in Samsung authorised repair center, maybe if you are lucky like me, factory warranty would be accepted.
I just told them I bought the phone second hand and it does not recognize SIM, did not go into details
force stop stuck on s6

The same thing happened to my G920P and I was stressing out looking for a solution. Finally, I figured it out myself.... I used idonne apps unlocking service awhile ago and still had their unlock app installed on my device. After trying repeatedly to no avail to unlock again I finally started looking thru the 3 dot settings and manuvered to the IOT HIDDEN SETTINGS TAB. From there I went to the "test mode menu" setting. Then to HW Test setting, down to #7 NV Rebuild All. Clicked that and let it do it's thing and all settings returned, no more stressing. Hope it works for you.
So I have a Samsung J3 (2018)(SM-J337A AT&T) I got from the US. I noticed that the WiFi doesn't work so I tried to factory reset it, thinking that would fix it. Nope, just made me stuck in the start. It just keeps me from moving past/skipping the WiFi connect because of the FRP and when I do try to connect, it doesn't connect even though it can detect. I tried multiple other WiFi connects like pocket wifis or mobile hotspots but no luck.
It gave a message at the start saying "Insert SIM Card to access network services." so I tried replacing the AT&T SIM Card with a local SIM Card but no luck either. It didn't detect either of the SIM cards.
Is there any way I can fix this?
