My SIM card is saying no sim or sim failure then it shows sos only on my phone. I’ve restarted my phone and also taken the SIM card out and blown out the port.

Did you try your SIM in another phone? Maybe SIM itself is defective OR if SIM shows life in another phone then your phone has issues.

@Maddox3 

sim cards rarely fail, usually it is the device itself

check if your phone is blacklisted first:

if it is clean, then test your sim card on another phone.  

if the sim card also fails to work on another phone, you will then need a new one.  Get a Public Mobile sim card from
