When I went to China last summer, I met a lot of [mostly businessmen] who had dual sim card phones.
In the late 90’s I remember clearly a device released that fit over your phone jack or connected to your phone and automatically dialed internationally using the cheapest provider for the call. (Nowadays, this would probably be almost universally utilize a VOIP calling plan to be cost effective..)
I wonder why more phones don’t have dual sim cards for international travelers, or this “switch to the cheapest plan” on-the-fly-type-system no longer seems to exist. I’m willing to bet that international travelers would love a phone that can switch between networks at their destination effortlessly.
Then again, maybe I’m just not looking in the right places..
