[Q] SIM failure

Hello i've started to have problems with SIM card, sometimes randomly it just pops up window that SIM card is not inserted and all i can do is restart phone and even when i restart it it cannot find the SIM card, i have to pull out the battery and reinsert the SIM to make it work, it might be because of the guy at t mobile who cut the SIM card wrong and it gets dislocated in the solo and also it might be system failure so im asking is anybody else experiencing this?

Yes I experienced this. It was really annoying. I managed to fix it by removing the sim card and wiping it gently using cloth. If that didn't fix it, then ask your carrier for a new sim card, because yours might have become defective.

SIM not detected
Hello, i have the same issue.
Nothing helps. Put in and out different SIM Card's. No one of all SIM are detected.
Could it be, that a self cuted SIM, to Microsim Formfaktor, damaged the SIM Reader of my new Note?
But yesterday it works really fine with the self cuted SIM. In the Evening i put out the cuted SIM und put in a other (Origin) Microsim from an other Carrier, that works fine too.
After that, i put the cuted SIM with an Adapter into my old Desire. Then i have issues with 3G Networks. The Desire find 3G Network, connect to the Network and lost the connection immediately. When i choose only 2G Networks it would connected.
Today at the morning, i want to know what's wrong. Desire or cuted SIM. I put the cuted SIM back into my Note. Boot the Note. If it booting up, it poped up a message, that the Phone must be restart because the SIM has been changed. When the Note reboot again it, it shows a SIM Icon in the Notification Bar and tells it's no SIM Card inside. I tried the other Microsim (OEM cuted) it won't be detected too.:crying:
Does anybody have a solution for me?

Thank you i tried to clean the SIM card a little bith with cloth and spits and grits, did not happen since then, i hope it will be solved, if not i will try to get a new sim card from carrier, after all the SIM card is like +11 years old

Buy only d855 version as a result you will lots of dev support....also. Have a easy ota update....d858 only have dual sim thats it

i think there'll be a huge battery performance difference between dual sim&single sim. you should consider that. maybe you can find another option with dual sim and better battery performance.

I have 3GB ram, 32GB, and dual sim. and battery is really nice... performance is better, and OTA updates are the same. (D856)

Thats not true. I got both, dual and single sim. and its the same thing. plus the dual have 1GB ram extra and 16GB extra storage. and extra sim slot. in conclusion dual sim is better.

I also have a dual sim. No such difference. Just yes due to dual sim it will take up some more battery. but still there is no difference I will

Problem With SIM 1 On HTC Desire 816 Dual SIM

Problem with sim 1 on HTC Desire 816 dual sim
Recently I got a hold of a HTC desire 816 dual sim, and when i inserted my "DIY" nano sim, the pins caught up and now they are broken. Now, I realize there is another sim slot, but it doesn't support 3g. So can I somehow make the phone think sim 2 is actually sim 1 slot, or maybe you have a better solution
P.S. I have a rooted phone with stock ROM

have you tried this as a work around?
I know It's quite tedious but if it works as a work around let me know. trying it out myself now
