Voip.ms is great for a simple SIP trunk but it has almost none of the programmable voice and other features of Telnyx or Twilio.

I had an horrible experience with VoIP.ms.

Every time I wanted to call a number in Europe I had to contact their support and go through "can you try now and see if works?" several time.

After 3 months I had enough of it and asked to have my provisioned credit reimbursed but they just refused.
