Android phone only detects certain sim cards?

Can anyone explain to me why my cell phones only detect and show that a sim is inserted for certain sim cards? For example, my S3 is able to detect a Koodo micro sim, but when I put in a Fido micro sim, it will not detect it and say no sim card inserted. Same goes for my spare dual sim phone. Any reasons why?

This could happen because your phone might be locked to a particular carrier. Search your device forum for help on unlocking.

[Q] Weirdness in SIM2

Hey guys,
I have a new HTC E8, rooted like any respectable XDA member. I'm from India and travelling to Singapore, and there's some weirdness with my Airtel nano SIM and the SIM 2 slot. I have a local SIM with 3G in Slot 1.
For the first two days, Slot 2 would occasionally disappear, with the phone claiming there was no SIM in it. Opening and closing the tray would restore the connection. On day three, this stopped working. No amount of reinserting would get the phone to recognise the SIM.
So I swapped the SIMs and both work. Swapped them back and the Airtel doesn't work in Slot 2. The local M1 SIM has no problem in either slot, but I obviously get only 2G in Slot 2, and the whole point of a local SIM and a dual SIM phone is to get cheap data when on roaming.
Help me figure this out? Either the Airtel SIM doesn't like Slot 2 anymore (it used to work), and refuses to work on it, or the phone doesn't like the SIM, or there's simply a loose contact (but that doesn't explain why the other SIM works).

Huawei honor 6 (single sim model(micro)) H60-L04 sim slot issue

Hi Team
I was having a honor 6 phone (Indian variant)
My sim was nano sim and I used it with the help of micro sim adapter.
When I put my new micro sim, it don't work,
I again put the adapter one it works,
Got a hard time figuring out that the culprit maybe the bent pins inside
But while doing these trials, the sim with adapter got stuck and i had to pull it out.After which no reception
But surely some pins are damaged as its not taking any network now
My concern is now this
Q1. Can only the sim slot be replaced ? or have to change full motherboard?
Q2.Any compatible sim slot for this device?
(H60-L04 sim slot not available and people are not ready to service )
Q3.will the sim slot of honor 6 plus work?
Kindly reply as this is a bit urgent
Thanks for your time
Vighnesh
Note that this is not similar to the international variant which has 2 sim slots
i think you have to change all
i had the same, send to repair and they change all
