I might have missed this but the calling issue for some customers with the implementation of VoLTE only affected calling.....not text messaging or data? Correct?
While @evanne2 hasn't confirmed whether or not data is working? (I'm assuming no at this point.) Do you also have no working services on your phone? Putting your Sim card in another phone and another working Sim card in your phone will help determine whether or not the issue lies with the device or the Sim card. If another providers Sim card is put in your device (especially another network's Sim card) that will also help identify if it could also be a network and/or provider issue.
If it's not just calling affected on a newer device (which would likely be the VoLTE issue) then in could be a Sim card provisioning issue especially if it occurred right after renewal. Much rarer would be the need to replace the Sim card but contacting customer support to reprovision the Sim card and reset the account would need to be attempted first and usually fixes the issue. Even putting your Sim card in another device and making a call or sending a text and reinserting it back in your phone can reprovision the Sim card.
Error messages such as the ones suggested by @softech could indicate a blacklisted phone if it was bought second hand or a Sim card that is not connecting properly in the phone due to a poor fit, dirt or debris on the Sim card or in the Sim slot.
A few more details will help narrow down the issue. The community can often help solve technical issues quicker than customer support or the tech department if back end access is not required to fix the issue.
Can you provide a screenshot? Do you have any bars / signal showing?
What troubleshooting have you tried? Have you reinserted the sim card?
Have you accessed your account to make sure you have paid?
