Hello! I have this issue with the phone that persists for a few weeks. It started when I tried to put another sim along with my current one. From then on, it really doensn't matter if I use the phone with 2 sims, 1 sim, or 1 sim in slot 1 or 2. Sometimes it shows no SIM Card, sometimes just no signal, sometimes no internet access but it has a 4g connection. I have tried to use it completly without sim and ofter some time, the Wi-Fi dies (goes gray in settings as well), and after some times it connects for 5 seconds, disconnects for 5 seconds and so on (so does the internet mobile connection). I have tried to flash global stable on it with TWRP, it seemed like it was a little more stable, but not *stable*. Today I have flashed Global Stable Miui 11 fastboot rom (xiaomi flash tool), no success whatsoever. It doesn't have warranty anymore and I would really like to try and find a solution.
At first I thought it was the sim card pins, but it is not because I have issues with Wi-Fi even with no sim inserted. Do you guys have any idea what the problem could be?

I have a very strange problem with my Thunderbolt that is connected to newer Gingerbread ROMs with Sense 3.0.
The thing happens is that the SIM card is not detected by the device in those ROMs (Gingeritis 3D Beta VII, Synergy and Liquid Gingersense 1.6. I have run them with the MR2, MR2.75 and the leaked MR3 radio and different combinations without any success. I have also updated the CWM to the modded 4.0.0.5 from 3.1.0.2 and completely wiped /system, /data and Dalvik cache between every flash.
When I flash an older Gingerbread like Gingeritis 1.2, the SIM card is detected again and contacts stored there show up. But immediately when a new Sense 3.0 ROM is flashed, it simply disappears which also removes the 4G connection of obvious reasons. The result of that is a complete loss of all data connection. It's possible to get 1X with the cover off (removal of the 4G antenna) but immediately when the cover is put back, all connection (including 1X and 3G) disappears.
All problems seems to be related to some kind of compatibility problem between the SIM card and the newer ROMs. My Thunderbolt is one of the first out there and it runs the first "Easy root" method that was released.
Beside this strange problem with the SIM card and the associated loss of data connection, it works perfect.
It would be interesting if there are any suggestions. I have double checked all MD5 checksums to be sure that all ROMs has been downloaded properly.
I am grateful for help with this issue. I would prefer to run the latest Sense 3.0 ROMs with working 4G.

My guess would be a bum SIM card. It really shouldn't act like that regardless of ROM or radio.
I decided, out of curiosity, to try with my T-Mobile SIM card to see what's happen. It can be read and show up in the phone book properly. So it seems like I have to order a new SIM card then.
It's a bit strange that the card fails this way because I've never experienced that with other SIM cards that I have used for years. But the inability to read it with specific ROM/radios indicates that there are some kind of compatibility issue. My SIM is one of the first they shipped with the Thunderbolt so perhaps it's a part of the bad batch.
I have now made some additional experiments including flashing the device without the SIM inserted. That removes all abilities to make calls, obviously.
When the SIM is reinserted, it found the network with a strong signal and calling works. I have now also noticed that saving contacts to the SIM works and the People app can show them properly. The only place where the problem shows up is under Wireless and Networks under the APN settings. When I enter that part, it says "no SIM found". Otherwise the card is obviously found by the device and calls are working. Data connection is not working though, it's only if I remove the battery cover that I can manage to get 1X working. So there seems to be something going on with the SIM in the 4G department.
My experimenting indicates that the SIM is working otherwise. When I tried other ROMs I have now noticed that the 4G is missing, it can't connect on 4G at all. The difference is that "SIM card not found" under APN settings is not shown.
Status for now with other words:
1. Phone calls works.
2. Saving and managing contacts to and on the SIM works.
3. APN settings presents the "no SIM card found" message. The APN itself shows up.
4. Data connection is not working with the battery cover on.
5. With the battery cover off, I receive 1X.
I have also tried to set it on CDMA (auto PRL) without any success when it comes to data connection with the battery cover on.
I have problem connection to my WiFi when I use my device with any GSM network SIM card.
Settings app will keep saying that it is connecting and the connection will never succeed. If I turn-off and turn-on the WiFi for couple of times WiFi may connect again.
The problem won't go away even after removing the SIM card. Doing a factory reset (without the SIM card) will clear this problem (WiFi will connect properly). But If I put the SIM card back, the same problem will come again.
Does any of you face this issue with you p3100 ? (mine is p3100 - India)
Same Problem
Facing the same problem, the wifi stops working after 5-6 mins, then I have to restart my device to get the wifi work again, but again it starts giving no connection error (with SIM or without)

yeah, I've got the same problem while connecting with wi-fi, got around it by simply disconnecting the wi-fi, clearing the saved setting & then searching for the connection again. Have to do this every time.....grrrrr
I had exactly this problem with stock ROM IMM76D.P3100DDBLF3. I do not have it on CM9 RC2.
I am not sure that it has anything to do with GSM.
FOR EVERYONE WITH WIFI AND SIM CARD PROBLEMS. THE FIX IS SIMPLE.

i have samsung p3100 after flash my tab imei 0490------------- i repair with z3x box now tab2 show no service pleace help me
Hi guys,
I've tried searching but have not found the answer. I successfully rooted and loaded AOKP, as well as CM10 and one other ROM. On all of them, I can make calls and use wi-fi, but can't get mobile data. The signal bar shows "3G" and "H+" at times, but never turns blue when wi-fi is off. I've checked http://support.t-mobile.com/docs/DOC-1976 (t-mobile site) which includes instructions on APN settings for data and picture mail, but that didn't seem to solve the problem. I've also tried turning Airplane Mode on and off, and I've done a factory reset and cleared Dalvik cache for each ROM. The SIM card is about 4 years old, if that matters.
Thanks a lot for the help!
Sounds like the sim card my sim card is less than a year old and randomly my phone doesn't have network and a message comes up and says to clean my simcard because its dirty or corrupt. So I turn my phone off take out the sim wipe it on my pants lol and insert it back in and its fine after that. I would get a new sim and try it out or use a friends sim and see if it works correctly if not then it sounds like the sim port on the phone itself.

I was hoping to find some answers here to a strange problem that's happening with my Poco X3 NFC.
This hasn't been much of an issue before due to WLAN coverage, but I'm more in need of mobile data right now, and wanted to use LTE instead of 2G or 3G which is quite slow in comparison. My provider does support LTE, I've checked everything on that end.
Whenever I turn on LTE, my phone immediately is stuck, gets a black screen and reboots to the recovery menu. After that I have to set everything to airplane mode quick, disable it, and then disable mobile data very fast to stop the loop. There's absolutely no such problem with 2G or 3G set, but as soon as I use anything LTE related it's stuck.
I've tried a factory reset, I've tried no SD card, I've tried both sim card slots. I've also tried every possible LTE combination set via *#*#4636#*#* and it happens with each and every one.
I've gotten messages and pages to load with LTE in my status bar, so theoretically the connection does work. It's just the bootloop afterwards that makes everything completely unusuable.
My phone is out of the box, nothing custom done or rooted. I thought that maybe a few MIUI updates would fix it because there were loop issues, but nothing helped so far. I'm running MIUI 12.0.8.0 stable right now, Android 10. I do have warranty, but first I'd like to know whether the issue might be fixable on my end.
Thanks in advance!
Same problem here
Hello,
here is my phone's issue:
after losing signal for a while ( for example when I'm in a garage) from time to time ( like 50% of these cases)the signal does not get restored. The tricky thing is it shows the GSM signal is just fine and the only reason I know it is NOT there is that there is no internet data by these range bars.... Obviously I cannot make a call and am unavailable. When I enter my house through the garage and the phone gets Wifi I can't even realize the data is not there and I might as well be unavailable for an hour or so... Sometimes the issue resolves itself,sometimes I have to switch to SIM 2 and back and that fixes the problem until the next GSM loss. I even got a new SIM card and factory reset the phone- with no results. It has been recently upgraded to MIUI 13 with no effect whatsoever... I have to use 2 SIM cards ( one for professional purpose). If you don't help me I'm going to throw this thing through the windows
Best Regards Chris
