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?

this phone is working without any problems and with every sim cards but yesterday phone shut down and now when i start the phone in display show sim failure only emergency calls but sim is inside and when i remove sim phone not start how can i solve this problem????
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!
I got my htc mini a few days ago. worked fine, and then it started to have no signal but data worked. so i got i new sim card from my carrier and all worked for a day.then the same thing happend. and the first sim card was micro sim card and the second was a nano simcard with adapter to micro sim.
I have trayd to put my phone back to factory settings, searched manually for network, trayd to remove and install the sim countless times with no luck. the sim card is trayd in another phone and it dosen't work there neither. and the phone is not rooted or anything like that
So i was wondring if it can be the phone that destroys the sim cards or maby i am unlucky with sim card?
Two months ago my Nexus 5 would start randomly losing signal or say that there was no sim card inserted. After a few reboots it would recognize the sim and let me use it normally, but when the device gets turned off and turned back on again there would be no signal.
More recently my Nexus 5 just says no sim card inserted but when reinserted it gets detected with no signal. Is there anyway i can fix this issue as i got signal yesterday but sadly restarted my phone because of a graphical issue and i lost the signal again. I have also done a factor reset and re-flashed android. Any help would be useful!
(Yes i have tried other sims and same problems)

Since the phone behaves the same way with different SIM cards, it could be a hardware failure with the SIM card reader.

Click to expand...
Click to collapse
But sometimes it will detect the sim and give me a signal and if i restart the phone it will not detect it again. If it was something wrong with the sim reader wouldn't it just not work at all?
Not necessarily because it should always detect the presence of a SIM card, active or not.
Most likely, there's a bad solder joint somewhere, it would work after a few restarts because the metal would expand as the phone heated up and make contact again. You could try to bake the logic board, might fix it. But, realistically, it's a long shot.

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,
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.
