When you check the DIGITAL meter by putting it on beep mode
The fourth and seventh leg should be between 300 and 500 at the end, the fourth leg is the ground in which the beep will sound.
Friends, if reading is coming in all your legs, then you can change your Sim Tray to another.
Your problem will be solved 100%, because sometimes it happens that due to water damage in the Sim Leg, it becomes salty due to which it is not touched in the Sim Card and that is why your Sim Card is not working.
Friends, we have got some Jio F220b and F320b sims outside some CPU IC, that too we will tell you through the picture, which leg goes till where.
Friends, if you like this information of mine, and your problem has been solved by this post of mine, then tell me the problem of any of your mobile through comment so that I can put it here in the post.
Thank you
