"Invalid Sim Card" message/ Error: ER05

I tried following the instructions here https://support.t-mobile.com/docs/DOC-33..., because I am currently using t-mobile, but it didn't seem to help me. How do I make the message go away? (I don't care about Wifi calling btw).

Answered! View the answer I have this problem too

Is this a good question?

I put my SIM card in the SD slot but upsidedown. We traded in phones.

Thanks for trying to help!

Hi,

Have you tried turning OFF WiFi Calling in your phone or make the cellular network the default option?

Go to Settings > Wireless and Networks > more > WiFi calling

Hi, Just a thought, have you contacted T-Mobile that you do not wish to be "registered" for WiFi calling on your service?

This is from the user manual for your phone:

"Wi-Fi Calling lets you make and receive voice calls and text /multimedia messages over your Wi-Fi network when your phone is connected to a Wi-Fi network and registered with your wireless carrier's network for Wi-Fi Calling."

Hello, this problem causes when sim card slot doesn't registered in Network, my advice is call your network administration for sim card registration.

You should register sim slot by that IMEI code in your network operator.
