I'm not a subject matter expert, but a Google Voice number can be used to receive texts and is protected by the relatively robust security of your Google account.

If the issue is the SS7 network, that won’t help unless the originating text is also in Google Voice.

That seems pretty possible though, if SS7 is the only issue then providers of 2factor SMS auth should just have a number on each network and when a 2factor request comes in they should determine what network its being sent to and then actually send the SMS from the number they have on that network.

Unfortunately, some services won’t accept a Google Voice or any voip number.
