What if all the other mobile phone companies were to attractively package twin sim or multiple sim card phones with one slot "locked" to their network? what if additionally the locked slot were to somehow be configured as the default permanently so that while you can receive and make calls on the other SIM cards, the process would be significantly cumbersome. Me thinks that while the green sim card would automatically take one of the slots, the operator with the default sim would eventually benefit. -- Regards, Collins Areba. Strategic Operations.
