I think that's acceptable. I expected a lot longer, to be honest.
As an alternative, I could instead just call both parties back once
the phone has camped. There's a number of ways to communicate the
wait, and I don't think users in rural areas would be particular
bothered by the execution. In my own experience in rural Uganda, they
went through a lot more hoops (e.g., climbing trees) for coverage.
