Try to login, EverSafe will send an SMS.
Then click "Didn't get the 2FA" ... then you'll get two options "Send again as SMS" and "Send again as Email"
While you're in Self-Serve, you can activate a new SIM card (if you already have the SIM card and can read the number off it) - you can't activate a new eSIM since to do so you need access to the app on the phone you don't have access to. Or you can report your phone as lost/stolen to temporarily suspend all service to it.
If you've ever logged onto your Self-Serve or your email from your missing phone then I recommend you change these passwords to secure your phone. Indeed, it's smart to change all your passwords to everything anyways, just in case, especially for your Self-Serve and your email(s) and your bank(s) and credit card(s) and payment site(s) and maybe even your social media site(s) - just so that a new "owner" of your phone cannot screw you over, steal your identity, drain your funds, etc.
Ignore the copypasta advice others are offering about this. If your phone is currently in the hands of a malicious or criminal person then every second could make the difference. Damage control immediately. Don't wait for a distant customer support agent/team to eventually get around to starting an impersonal support session and asking you questions ... by then it might be too late.
