did you cut the sim to micro sim size manually? if yes than check the contact ppoints.
if it was already micro sim when you bought than something might be wrong by hardware side.

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.

[Q] Please help - Galaxy S6 edge 'No SIM Card' problem

Hi folks! My new galaxy s6 edge is showing 'No SIM card' always. When i inserted the sim for the first time, i was able to get the network but after a while it started showing 'No SIM card' . Later i updated my phone software to Android 5.1.1. Then for a minute or two i was able to get the network. After that it failed to read the SIM card. I even tried with different sim cards. But no luck. On the hardware side, the sim insert tray and sim card looks perfectly fine to me. I guess it's a software related problem. Is anyone also facing this problem? Is there a solution to this?

Second SIM slot stopped working after update

A really weird problem appeared on my device after upgrading to the latest miui 8.7.19 global beta from the 8.7.12.
After this update my secondary SIM slot stopped working. It reads the SIM correctly but it can't connect to the network.
If I put the same SIM on the slot1 it works, if I put it on the slot2 it doesn't work.
It's driving me crazy because I have the need for 2 SIM for work.
I already tried to revert it back to the old ROM via fastboot formatting the phone but it did not help. The problem is still there.
Can someone please help me? thanks.
