Ya there is some stuff that is out of control. I work for a SNL telco company and we tell our customers anywhere from 7-15 business days.

Reason for this is due to amount of staff, and also if a port gets rejected. Losing carrier can be petty and reject for various reasons. Wrong Adress, account number etc.

Depending on the company port times can take 5 to 10 business days or longer.

What about point to point internet? Is that an option?

Using the 4g/lte you have two options.

Use a cloud service or host it yourself and get apps on your phone and use lte from your phones. Usually it will run fine. But make sure you host it in the cloud.

Or get a 4g/lte router and do it that way. But you would have to watch out if your using an on premise system as some of them require port forwarding and you usually can’t do that on a 4g/lte internet due to being shared. You’d still have to look at using a hosted service.

I primarly use 4g/lte for backup for VoIP but then have some type of stable internet inside.

What about satellite internet?
