Yes, my mobile phone number has not changed in 25+ years :) - so SMS
reception was still possible.  It has been an inconvenience as well,
at times, when mobile reception was spotty, or Amazon decided to send
not a 4- or 6-digit code, but an URL with a 32-byte random identifier -
to my Nokia 208, which does "SMS and voice", but no "Internet"...

If going for SMS 2FA, I think one should take into account that it's
known to have attack vectors - so maybe combine that with an e-mail
"SMS 2FA has been used to log into your account from an unknown 
device", etc.
