If cell service is available in at least one area of the property, you could have a dedicated sim for receiving SMS 2FA and use a 4G router to forward the SMS to an email, e.g. Teltonika have this functionality [1].

The 4G router also has the benefit of being able to use externally mounted antennas. Which might help in low signal areas.

Not ideal, but might at least be a solution for some people.

While that is a solution someone could use, it wouldn't work for the subject here:

Yeah wont work for everyone, but a directional antenna mounted high up on house might have a better chance than a phone antenna.

The idea of mounting a directional antenna "high up" on a house (or paying someone to do it) for the purposes of receiving SMS 2FA seems wild.

You can also get antennas with suction cups. I have used this before to get 4G internet in a house with no access downstairs, by sticking the antenna on an upstairs window.

An outdoor antenna would be better, but yeah more of a pain. I guess it really depends on how badly someone wants SMS.

MOUNTAIN valleys, need to get WAY higher up than the top of the house.
