[Q] Dual Sim Problem - Xiaomi Mi 4i

Is anybody else facing the same problem as me?
I can't use sim 1 for outgoing call, and I will get the message "number unreachable". After rebooting, the issue seemed to be resolved by itself. But not too long after that, the problem appear again.
I noticed it happening since a few days ago. Any ideas how to solve it?

Nope not me

No SIM error

Hi Everyone,
Are any of you receiving the "No SIM" error? My VZ S3 will start up fine, but within a few minutes, it says No SIM at the top and then the radio restarts. It will do this a few times and then the radio will just lock up. No data or voice. I took it back and they tried a few different SIMs including the SIM from my Nexus. All of them did the same thing. I asked for a new S3 and they wouldn't exchange it because they've been told it is a known issue and Samsung is working on a fix. Anyone else having this problem or know of a workaround?
Thanks,
Rob
Sorry if there's another thread on this. Searched for No SIM error and didn't find anything

Yep. Mine never fully locks up, but it happens constantly. Was gonna return it but from everything I've read Verizon won't do anything about it. Just waiting on a fix from Sammy.

I went to a different store. They replaced the phone and used the SIM from my Nexus. It's been working for a couple hours now, and before I couldn't get past a few minutes. I also got an apology for having to go to another store.
I had this problem only once. I believe it has something to do with the cell tower. This particular area I was in had 4g/full bars. Once I got to this job site. I tried to make a call and I got a "No SIM" error. Then my service status would change to a "No service" Icon. Seconds later 4g would come back up. I was at this location for 3 hours. I tried to make many calls/texts within that time and out of 30+ attempts I was only able to make 1 call. The rest were "No SIM". Once I left the area...2 miles out. I was able to make calls. I have not experienced "No SIM" error since then.
Mine was definitely not location specific. It happened everywhere from Milwaukee to Green Bay. I still have not had it happen on phone number 2.
I've been dealing with the same thing. Mine appears to be location specific. It only happens when trying to make a call or sending a text. I can use data all day without a problem. I've had my phone and sim card replaced neither fixed it. I tried loading cm10 to see if that would fix it but instead of saying "no sim" i got the locked sim card prompt asking for the pin to unlock it.
As for samsumg working on a fix, I've called them several times and every time they assure me that this is the first time samsung has ever heard of the problem. I've given up on them and just hope this becomes a big enough issue for our devs here to take a look at it.

[Q] Random no service fix?

Hi, my HTC One S sometimes displays 'no service' when the phone is booted. A restart fixes the issue. This only happens when I turn the phone on first thing. Spoke to HTC about it and they said it sounded like a sim problem. I ordered another sim from giffgaff and still have the same problem but not the 'restricted access' messages. I have googled this and people seem to have had the same issues with this device but the posts have never detailed a solution. Is there one?
Thanks.

[Q]I need precious Help

My HTC Explorer is two years old and everything was working fine, suddenly i got an issue. whenever somebody call me i didn't get their calls. If i'm using my phone and somebody gonna call me yea i will receive his call but when my device in sleep mode. i didn't get any calls. I've tried other sim cards. I've unlocked bootloader and flashed again stock rom but issue is still persist. I'm assuming, it should be hardware problem. It's been two months passed since I've not find any solution.
Does anyone has similar issue?
Is it software related or hardware?
I will appreciate it if anyone could help.

No SIM

I have been getting a no SIM error on my Verizon Note 5. Probably happened 5 times in the past 2 weeks. Reboot temporarily fixes the problem.
Anyone else having a similar problem? I will probably try to get a new sim from Verizon.

No issue here. Have you re-inserted the SIM card? If that doesn't help take it to Verizon.

Yeah, that was the first thing I did. It happened 3 times yesterday. I will call and get a new sim.

Same problem here. Was really bad last week and now hasn't happened for a couple of days.
I ended up getting a new sim card yesterday from Verizon

Happens to me at least 2-3 a week. Also drops from 4G to 3g, and sometimes my service doesn't even work. A coworker who has a Note 4 on Verizon mentions he has to restart his phone every few days as well because his connection just goes out sometime. I don't know if it's a software issue or if Verizon is just being ****ty right now
I finally got the sim replaced today. Hopefully this will fix it. Really don't want to reset the phone or exchange it.

I have had a new sim for a day now. The error has not popped up again yet. I will check in again in a couple days.

Just got the error again today. Thought I was good.

I was having the issue quite regular and, took my sim out and cleaned it (wiped) off what looked like dirt and have not had the issue yet.

I had the error once or twice since I swapped Sims. I have not had it happen again since that last post.
The only thing I did is clean the sim card and blow out the sim port.

I ended up going to get a new Sim and no more issues with it. I do see any times I lose data connection and then it reconnects.

I was at Verizon was out when my phone froze...waited 1.5hrs, when all needed to be done was hold the power button and the down volume button simultaneously to create a battery disconnect to reboot....I asked about this same issue as I was doing a system reboot when the Note 5 froze....she said the phone when not receiving service will automatically switch to "global" to maintain connection but can't switch back...need to go to settings->mobile networks->check the network mode to verify it's in the lte/cdma mode, if not select that.....IDK, it happened at my house where I have a network extender, so that shouldn't have happened.....saw this solution somewhere else....saying the slot may be a little loose causing the connection to be unreliable, I'd start w/ something thinner than copy paper first....or wait for the "masters" to comment....:
If there is a little room for SIM movement in the slot then the contacts between the phone and the SIM will not meet causing this issue. Try to cut a piece of paper the size of the SIM card and place it on top of the SIM ( not on the side where the gold connector is). Insert both in the SIM slot then check if the problem still occurs.
This happen with my galaxy 4, and i changed the sim card, but the problem still happened, now my new galaxy note 5 start the same way. Sucks
Me too
I have been having the same issue twice a day now for at least a week. Guess I need to make a trip to the Verizon Store.
I had this same problem, started out once a week, moved up to a few times a week, then finally when it was a few times a day I went and got a new sim. They told me if this doesnt work bring it back in and they will give me a "new used" phone.
2 weeks without the issue, phone bumps the nightstand a little too hard and starts happening again.
I pulled out the sim tray, cut a piece of packing tape to match its shape. Put the sim in and layered the tape over it. Seems to have resolved 99% of my "no sim" issues. I say 99% because it happened once in about 6 weeks since I taped the sim in place.

Honor 8 - emergency call only

I have a really weird problem
I have an emergency call only message, the problem comes once in a while and it disappears after 10-20-30 seconds.
All was fine on my first honor 8 but I have changed/returned that device because of a faulty camera. So I got a new one + I bought one more for my wife. Now both devices have the same problem. I have even tested a fourth device (still honor 8) and I have always the same problem. I don't know if is a faulty SIM card or not because it was working on the firs one and I'm talking about two SIM cards....
Any suggestions/solutions?
Thanx

Try switching the network mode to 3G or 2G. Maybe the cell signal is a bit weak in your area.
I think it would be weird for all phones to have sim issue.. that it is a faulty sim.. you should change to new sim..
Try a different Sim on both devices, if it's not fixed, then try a factory reset
Hii @badcop
Did you solve the problem??
Please report back so that we also can know what to check and
to do if we bump in some kind of same situation..
Thanks
If nothing works, just rollback to MM and factory reset

I've tried to do a factory reset but the problem was here, and i'm using two SIM cards on two different phones with the same problem.
I need to try the first solution - switching from 4g to 3/2g instead of automatic.
Thanks
Did it work?!
