SIM Card Does not Recognize. - Android Q&A, Help & Troubleshooting

I use Lenovo A789 (A789_S223_130206) . I have rooted (boot image) it with SP (SP_Flash_Tool_v3.1222.00) flash. After rooting all is fine but SIM card is not recognized? have you any Idea? How can I able to recognize SIM cards? please help me

Am not familiar with lenovo devices.. But is the sim not recognized whatever you are doing or how often you reboot.. I once had the problem, that sim wasn't recognized because it was very old and perhaps broken.. Maybe this is the reason..?

When I first got the phone both slots worked. I've rooted the phone and installed some things and may have broke something. SIM2 works but the other slot is broken. I'm on tmobile too.
Feiteng GT-A7100 "Mobile Network Not Available"
Oh, gosh, I'm really stuck. Tried two SIM cards (redpocket/att and spot/t) and either works. Sim cards work with
dumber phones. Really like this phone (ie cool android hardware) other than it won't work as a phone.
I also have suspicion about the IMEI. Bought from everbuying.com. please email vjp2 panix com because I dialup and don't
have broadband. But I will try to get back to forum if someone replies. The Phone sees the SIM card (ie, knows name, and some addresses).
I don't know about all those extra setting with initials (some it has, others not).
But it says the SIM card is disconnected. Took it outside, closer to cel towers. Is it possible the sim cards are too cheap.
I only want talk. I've seen doc this phone is 4 bands, others say 2 bands

i have same problem
1) I noticed one of my sim slots (sim 1) was not detecting the sim card. Error message was something like "no sim card" which is different than "no service". In examining the sim slot, one of the gold pins in the slot was not making contact with the sim card. I took a small safety pin and bent the pin slightly up.
** NOTE ** be careful bending this pin up. If you use too much force, you can snap the pin off and then you would be totally screwed.
I then reinserted the sim card and the phone detected it since the pins were now making contact with the sim card.
2) Another thing I noticed is sometimes I get "no service" even though other times I would get 4 bars of signal strength at the same location. I went to settings and disabled the sim card. Waited about 10 seconds and then re-enabled my sim card. It then seemed to reconnect with the phone network.
My carrier is TMobile.

maybe the sim card is not properly inserted or there must be any problem with the sim tray, my advice is to take the phone to a service centre

Very same issue here. Quite a big disappointment because my spouse chose this one out of a Sony Experia Z, Motorola Razr and two Chinese Samsung clones. Anyone with a solution?

Yep, replace for a new SIM card.
That doesn't fix a locked slot. If the slot is locked and not the sim itself I haven't a clue how to fix it. I'm dealing with the same problem. I can use the same sim in one slot and it will work and in the other slot it says the slot is permanently locked. IT IS NOT THE SIM THAT IS LOCKED.

No sim card detected

Hello,
Redmi 5 Plus it stopped to sim card detected, I have been read that this problem appears after the update.
I try to unlock bootloader for install new soft but one of the steps in unlock bootloader is to insert the sim card and start mobile data - but no sim card detected.
Any ideas?
Thanks.

Try different Sim card, mybe yours is damaged.
If new SIM card is not recognized, well you have 2 options:
— hardware issues
— Persist partition is damage.
For persist you can search XDA forum for solution.
Good luck.
