Mate 7 - no sim card deteced? - Ascend Mate 7 Q&A, Help & Troubleshooting

Hello,
today I bought an Mate 7 (secondhand). The Mate 7 is working fine so far but it isnt recognizing my SIM Card!? I tried several SIM Cards but always the same problem "no simcard inserted" and i can only do emergency calls.
Luckily I got the original bill ... do i really have to send it to huawei for a repair? (still got warranty) or is this a known problem and i can fix it by my own?
Greetings from Germany

Yes, you have to. Furthermore, it is secondhand. You don't know what the other guy did with the sim card slot

In my case everything was working fine, just a battery drain issue which led me to upgrade to lollipop and then it was still working great, reception has even become better. Then for some stupid reason I decided to downgrade back to kk and flashed b300, after this flash everything worked fine and I proceed to flash b137 which was there originally when I purchased it. Flashing went smooth but... no sim card detected.

Tilt SIM issue

I have an At&t tilt a friend purchased that I have SIM unlocked and updated to the default shipped HTC rom with Radio v. 1.27.12.11, after several hours the phone can no longer read the SIM card and comes up saying the sim is missing.
If I reinstall the At&t rom and replace the bootloader to stock versions the phone is again able to "see" the SIM and works normally.
Does anyone have any ideas as to why this is happening? My intuition tells me it's the radio but I have done this to 8+ Tilt's and have not had any issue with any of them. (all of them are using radio 1.27.12.11 also)
Hi
this looks like a damaged SIM, try and contact your service provider to replace the it
Thanks, I've tried that.
I've tried putting a known good SIM into the phone with no luck. And if I put the SIM in question into another phone it works perfectly.
i flashed my Tilt with dutty's v3 rom with the 1.27.12.1 radio and had no problems whatsoever for six days.
I flashed my friend's Tilt with the same rom and radio and put my working sim in his phone to test voice quality, etc and got "Sim is missing error." I put a second working sim in the device and got the same error.
I now get the same error when I put both sims back into my Tilt.
I've done a hard reset and flashed 1.27.11.31 and issue persists.
any help is appreciated.
edit: I reflashed the radio. Now one of them is working.
I'll keep at it.
OK, Now after flashing both the HTC and AT&t roms several times as well as all of the radio varients I have determined that something is wrong hardware wise with the phone.
No matter what ROM I flash the sim card cannot be read and furthermore if I then flash the stock bootloader and "lock" the phone the SIM can be read for a period of about 10 minutes.
This is very strange and I can find no good explination for this behavior.
I am flashing the origional At&t rom and bootloader back on the device and sending it back to At&t.

hi so u mean u simunlocked your kaiser130 but how,, im unable to unlock my kaiser 130 locked on uk orange ---regards--cpukiller
I had this EXACT problem. My sim would work in my old 8525 and in an ETEN x500 but kept coming up NO SIM FOUND in my Tilt...It was a brand new TILT and I could not figure it out.
I put a little piece of tape on the lid of the sim card holder on the inside. It puts a little more pressure on the bar that holds the Sim in place and Voila! It recognized the SIM and I have not had a problem the last two weeks.
Give it a try...
I had the same issue with my kaiser. I was able to resolve the issue by applying pressure to the bar while shifting the SIM laterally. Sounds like there's a minor manufacturing issue with the SIM holder.

Just wondering, at times my phone drops signal completely. But only for like 30 seconds to a minute. Do you think it's possible that it "loses" the SIM card?
Or is it more likely that the Kaiser just has poor signal quality? Mine will drop signal even when in a 4 bar area, and when next to other phones on the same carrier which remain at 4 bars.
I would try it...I get very good reception with my TILT. I did try the putting a little pressure on the sim card initially and it would boot up and show the SIM but I would lose it quickly. I tried the little piece of tape as the next step. You don't need much, I used scotch tape and just a single layer so it doesn't add much pressure, just a little bit.

[Q] help with spontaneously unrecognized SIM card

Ok, I'm going to give you guys the whole background story just to cover all the bases.
I've had a Nexus S for about 6 months, never had a hitch. Rooted it, etc etc all fine and dandy.
About two weeks ago, I updated it to CM 7.1 RC1. So far so good.
I've always had the same Vodafone SIM card, which has accompanied me through a couple of phones. Last week, I went to London and bought a UK pay as you go card, to use data without roaming. Perfect. No problems whatsoever.
So, to make it clear, I never had problems with my original (portuguese) SIM card, nor with the british one I had just bought.
However, it was upon my return that I realized I had forgotten my SIM card at my friend's house. I quickly stopped by the Vodafone store at the airport, where they promptly gave me a new SIM, ready to use within a couple of hours.
Since then, my phone after a short period of being on, spontaneously fails to detect the SIM card/no longer recognizes it. I've tried scanning for networks in the settings, but it won't let me register again. It takes a reboot to get it working. Thing is after a couple of minutes or hours, it happens again.
I have since exchanged the new SIM card with a newer one , also from Vodafone, albeit a different store. Yet, the problem persists.
I didn't alter any settings between Portugal-UK-Portugal, so everything should be exactly the same. Does anyone know how to solve this or why this happens?
Faulty phone?
Faulty radio?
Faulty SIM cards?
ROM bug?
Any help is appreciated.

No SIM Card?

Sorry for the spam.
After I was finally able to get this phone working, it worked great for a few hours before losing all signal and telling me that it couldn't find a SIM card. Naturally, I was confused. (It dropped all service after 20 minutes earlier in the day, too. Airplane mode fixed that.)
(Phone is unlocked and rooted with Ace Tool Kit; I use T-Mobile.)
Now, when I put a clean AT&T SIM in there and reboot, it reads fine and has no problems fetching APN information. The T-Mobile SIM, on the other hand, does not fare as well anymore. I also tried another active T-Mobile SIM to no avail (works on BB; does not work on this phone).
I'm thinking that something is going on with the radio and it's tripping up the OS. Has anyone seen this before? Should I flash a new radio?
Thanks!
Try a layer or 2 of tape on the back of the sim card so it makes better contact.
It actually turns out that powering the phone off for about 15 minutes or so fixes this problem. I'm guessing there's a bug in the baseband that causes this.

Xperia Z5 E6653 SIM CARD ISSUE

Hey there, everyone.
I've had my Z5 for over a year now, it's been running completely fine and have been happy with the phone. However last Wednesday my SIM card doesn't seem to work anymore. Let me rephrase that, the Z5 no longer reads the sim card. I have tested the SIM on two other phones ( one Locked to O2 and one Unlocked) and the SIM does work on both.
I've tried many things such as :
Searching Google + XDA, however the threads seem to be 2-3 years old.
Hard resetting the phone
Taking the SIM card out and gently cleaning it
Upgraded phone to 32.2.A.5.11
Downgraded the phone to 32.1.A.1.163
Tried to turn the Radio ON in the *#*#4636#*#* , didn't do anything, won't turn ON.
doing a factory reset did not work.
I am beginning to think the SIM card slot inside the phone is somehow damaged or moved position.
Any ideas? I'm stuck.
Guess it's an hardware problem, if so, you're screwed but if you have a warranty (seller or Sony) try to use it, I can't help you further sorry mate

Question Insert SIM Card Problem

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.
