Hello guys. I remake phone to work with 3G (solder sim slot in service just like in guide wrote) But now my phone sometimes (2-3 times in day) is missing SIM card. After reboot the SIM is working fine, but in few hours SIM is missing again and reboot needed. I know that the same problem was with another phone another man (i found out it on russian forums about Photon). Any suggestions? Can somebody help me?
I had the same problem. for me it was just the case. there was not enough space for the sim so it get pressed all the time down on the side
and the other side was coming up. that was making problem with the contacts of the sim reader.
Yea, I would think a loose wire/solder or some clearance issue with the SIM slot...

Hi there.... There are 2 possibilites here... The first is that your sim "went"... This is the least likely of the features, but it can happen (happened to me).. The more likely senerio is that your sim is just loose underneath. I used to have (Actually I still have it) a mpx200 as well.. It was a GREAT phone, except the sim housign was poorly designed and the sim cards dont; always hold a good contact. I suggest that you take out the sim card and reinster it.. The also fol a small piace of peper in 1/2 and place it over the sim card under the battery... that seemed to help a lot with my phone... Sometimes my card would do that in the middle of a call.. very irritating. Let me know if this helps!
Hi !
My Htc one S sometimes show the advice that indicate that there is no SIM inserted, even if the sim is there and even if the phone is already power on, it shows the message after some times it's on. Any suggest?
Have you tried a different SIM card? Could be something wrong with the card. Also make sure all the contacts on the SIM and phone are clean.
If it still doesn't work then looks like you'll have to go back to HTC.
My SIM didnt work in my S when I got it.
After some googling it seemed quite common on the X.
The general answer was "get a new SIM". I got a new SIM and it solved my problem at least.
If a new SIM doesnt work, it might be a hardware issue with your device and you should probably return it.
actually I just have one micro SIM and I cannot try a switch. Also in order to try I would need to take the other sim for long time because this happen with a low frequency..
Get it exchanged from your carrier. Shouldnt cost much, if anything at all (Telia here in sweden didnt charge anything at least).
Hello,
Sometime two times per day I got this message: Sim card hot plug alert. In this time SIM 1 is disabled. I see that phone do not see the card. SIM car do not work. After restart everythng work well. Phone is nearly new and I have this problem all the time. It is bad because sometime I dont see this and I am not available on SIM 1. Sim card is new 4G and I had a same problem with old SIM card. Even if phone is on the table this heppend. I put tape on sim card to make better contact but is the same. No efect. Anyone know what is problem?
Hi, I had one plus one updated and I decided to flash LineageOS to it.
after I did it I got an error that sim not found , after searching in google I decided to go back to stock ROM. (I followed this tutorial https://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541)
Now I'm still getting the error SIM not found.
I can see my IMEI.
I have the latest version(no updates)
I looked in FAQ and did a search in google ' didn't found solution.
it worked for a few minutes with LINEAGEOS but then stopped suddenly
my SIM works fine in other phones
Happened to me as well. Sim would work fine on other phones but not on my OPO.
Take out your SIM and place a piece of paper on top of it before placing it in SIM card tray. Insert and reboot.
Solved the problem for me. :good:

works. thanks.
Happened to me and to a friend before and i can confirm that it works. It all started when the nano sim adapter got stuck juuust a little bit in the sim tray, so after removing it i was unable to get the sim to work , so i tried the method with ductape, and it worked, and one day i dissassembled the phone to change the camera and i find out that the some of the pins in the sim tray got cut and became shorter so they couldn't reach the sim card preperly, and adding the ductape would push the sim card to it so it can make a proper contact, but i found it ashaming to put so thing and fragile pins like that because i can assure you that i didn't pull or force the sim adapter, but i was just shaking the phone so it can fall.
HI,
I bought my son A53 in best buy in the United States
my phone version is SM-A536U1/DS I was told the phone is unlocked
I am in Israel now and everything was fine for 5 months and I had no problems
but in the last week the phone cant find my SIM card and I get a message saying
Insert SIM Card and my phone cant find the SIM
What Can I do to fix this Problem?
well either there is hardware fault or maybe the sim cannot be read.
i suggest try cleaning the sim first with a soft sponge or q-tip. If the problem persists try blowing compressed air in the sim slot. If that doesnt work either try your sim in some other working phone. If it works then your phone is faulty.
