Hi,
I know a question like this has been asked many times, but I'm at my wit's end.
It's about my dad's phone. He got a new one (Samsung A22), and a new provider. It worked for a while. Now he cannot make any calls anymore and cannot receive calls (data works). But now it gets strange:
I put my sim card (same provider) into his phone, everything works.
ok, maybe his sim card is broken, but no.
I put his sim card into my phone, everything works.
We also already got a replacement sim card, same problem. And we did a factory reset on the phone, nothing changed.
We called the provider and they tried a "reset" on their end (not really sure what exactly they did there, customer support), no change.
So, if the phone is broken, why does my sim card work and if the sim card is broken why does it work in my phone.
If anyone has any hints, I'd be very grateful.
Hi,
have found how to fix this issue? It's happening to me now, and i don't know what else to try to make it work.
Thanks
Re-flash Stock ROM.

A couple of weeks ago my phone started generating an SIM error message at startup.
I then changed ROM from the Orange WM6 to the latest HTC version, and since then i get the same error message.... Missing or invalid SIM please contact you service provider....
The weird thing about this is that I still get the error message, I clear it twice, and it asks me for my PIN and continues to work just fine... I thought that changing the ROM would sort this as I just put the error down to some sort of OS problem initially.
Anyone else experienced the same of similar issues?
I replaced my SIM to see if that made any difference but that hasn't changed a thing either...
.G.
the same here. don't know why..
hi! ive had alot of experience with phones giving similar errors. found its one of two reasons..
1) the phone is blacklisted. its weird but blacklisted phones works sometimes and other times it gives some sort of invalid sim error.
2) the sim is just simply not making proper contact with the metal pins. in nokia phones i usually just put a small piece of cartboard or thick paper in between the battery and the sim and the pressure forces the sim closer to the pins.
dunno about vox tho. put its worth a try
I get the same problem, with an O2 SIM card in a HTC-branded S710. Sometimes it happens, and sometimes it doesn't.
If it happens while turning the phone on, then I find that all of the sounds are playing faster than usual also (things like message and call tones are high pitched). If I go into Comm Manager, put it into flight mode and back out again, it not only finds the SIM card properly but also fixes the sound issue.
I wonder whether it's something to do with my SIM card possibly being a USIM card instead, since it says "O2 3G" on the card, but of course, the handset is not 3G-capable.

My excalibur (HTC 620) phone has exactly the same symptoms with a USIM (3G). It has no problem with other 2G SIM.
I am not sure whether it is something with the ROM. I flashed my phone with wm6.1 rom cooked by Kavana.
I had the same issue with one of my 3G SIM's. Eventually I didnt know what else to try so I got a SIM swap and thats solved the issue. Not a single problem since then
Hey folks, i tried searching here for my issue. I found many similar threads, but nothing that solves my issue.
Two days ago i started having issues sending picture messages, today i start losing network signal until it cut out alltogether.
I tried multiple sims from different carriers and got nothing. Ive tried the following:
Factory reset.
Rebooting and reinserting sim
Resetting apn settings, custom apn settings.
I have WiFi, and the symbol says "no service" nothing about emergency calls only.
The new information i have, which i didnt find on other threads here is this; i found a sim card app and tried it, its able to pull my sim card information off the card, (phone number etc.) yet i get no cell service. Any ideas?

Hey @kimsgrim
Hmm so u already did a factory reset? And didn't restore anything before test?
Really stock or u changed anything (Rom or Kernel)?
But ur phone doesn't say "No Simcard found, please insert and reboot" or kind of that?
If no the simcard is fine and the phone also seeing it. The sims u tested where card which definitly work on other phones?
So two things possible in my opinion:
1) System problem: Anything is reset or not working, which should be done with a factory reset or maybe flashing another stock firmware over
2) Hardware defect of antenna. Would be sad, but no other point for be atm.
Much success
CHEERS
Sounds like the sim card reader is messed
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
Hey!
I have a strange problem with my Mi4i (MIUI 7.5.2.0). The phone shows "no signal" or "emergency calls only" with a specific sim card, which works in other phones and used to work in the phone in the past.
The device works well with other sim cards too, even from the same provider. Just not with the specific sim card, which happens to be the one i would like to use. I cannot remember if the problem occured after an update (ota only).
I have tried so far, without any effect:
- a factory reset, without deleting the personal content.
- ordered and tried a new sim card from my provider
There seem to be similar threads in this forum, but they do not adress exactly my problem afaik.
Does someone has an idea what else i can try? I will provide further information if needed.
Thanks in advance!

Might be an unsupported band. What phone have tried the sim with?
Thanks for reading . Oneplus One, iPhone 5C. Sorry i forget to tell the sim card worked in the Mi4i. I didn't use the phone for a while and i might have updated it (ota) when i turned it on again recently. I guess the problem persists since then.
Any chance the update caused it?
did a full wipe and reinstalled miui (7) in fastboot mode. no change. the sim card works fine with other phones. the phone works with other sim cards fine too. just not with my main one
I have a new sim card, it works great with my other phone,
but my oneplus One does make an issue out of it.
I just did a factory reset and it finally worked after trying every other trick (airplane mode on/off, taking out the sim card...)
I tried other sims and they do work 2/4, the sim out of my other phone didn't.
I have no idea whats wrong with my phone.
I am trying to factory reset it one last time, as I suppose it's taking my old apn setting from my google account.
I will try to go without play store for awhile if that works.
EDIT: ok, this didn't work. I didn't even connect to wifi this time, maybe the sim's dead?
But why is it still recognized by my other phone?
EDIT2: Just called the carrier, the issue is with my phone, as they do not block any models and oneplus one usually works with them.

I spent 48h to fix it...^^
