Not only SMS-based two-factor is susceptible to phishing, its also susceptible to intercept/forging by the rogue governments (RU) https://meduza.io/news/2016/04/29/mts-otklyuchil-oppozitsioneram-sms-servis-vo-vremya-vzloma-ih-telegram https://meduza.io/news/2016/04/29/mts-otklyuchil-oppozitsion... And very limited security in SS-7 makes it possible to hijack the messages even for the foreign phone numbers.
(Edit) Just to point our, here I talk not about possibility of sms interception - I'm talking about sms intercept that DID happen in 2016 and is widely publicised and have a lot of sources, including timeline of this event and comm with the mobile service provider(albeit, this info is mostly in russian)
