While one can still buy a prepaid SIM card without ID in the USA (though I don’t expect that to remain the case for long), there are plenty of OPSEC slipups: if you top up your account with a bank card in your own name, the mobile provider will associate your identity with the SIM card. If you leave the phone with that card turned on overnight at your own home, it is trivial for the mobile provider or authorities to link that SIM to your own identity, etc.
