I purchased this phone with the understanding that "Calls made within the wireless network will not be deducted from your plan's minutes, which allows you to get unlimited calls and save money at the same time". However that has not been the case with my Samsung T409. While this maybe the case with the additional Home Router, calls made using while connected to open wireless routers still used my alloted monthly minutes. Bringing along the home router where ever I travel is not a feasible solution.
So what's the point in this phone? If it was to unburden the overburdened wireless network, then yes it saves the carrier, but it screws the end consumer as there is really no benefit. One of their other selling points has been that you can now receive better signal strength in areas where wireless signal strength was low, but WiFi access was available such as your office or home. If that was really the case, why wouldn't anyone not just set their phone to Forward calls to their Home or Phone either.
I'm also pretty distraught at the use of the term "Unlimited" as in "Make unlimited calls to anywhere in the US". It should be more like, "Make unlimited calls to anywhere in the US and we'll bill you for it too..."
I'm also disappointed with this phone as I was in an International location (Canada) and found an open WiFi Network, I made a call and was charged the International roaming charge even though I was connected via WiFi. If it's the International roaming charge for Canada while connected via WiFi it's will be the same for International roaming charge when connected via WiFi while in Europe or Asia. What was the point in this phone?
I've had this phone for a month now (Dec 07), my cell service provider is T-Mobile and I'm disappointed with the purchase of this phone.
