For $5 you can get a travel wallet the size of a credit card that can hold multiple sims - probably cheaper than a dual sim for a very small number of users.
Of course that doesn't help business/non-business accounts but personally I wouldnt want the extra bulk of handling two sims in one phone when I didnt need it.
