Or make dual sim phones widely available instead of keeping them restricted to either crappy phones or emerging markets.
Allow one sim to be assigned to the personal partition and another to the business.
I have to wonder if the main fear about making good dual sim phones widely available is the loss of revenue by the networks when we keep our home country sim and drop in a payg local country sim beside it. It removes any chance of them reaming us on roaming data and call charges.
