Samsung B7722

Samsung B7722 has separate phone numbers for GSM and 3G networks

               Dual-SIM mobile phones (two phone numbers in one phone) have many useful applications. Some families, who like two share their mobile phones, keep one SIM card always on the phone and let the person who is borrowing the phone insert his own SIM card to the other slot. Samsung, on the other hand, has designed a dual-SIM phone for frequent travelers.

              The Samsung B7722 mobile phone can host two phone numbers. It comes with two SIM card slots where you can insert any unlocked SIM cards. Separating the GSM and 3G network connections between the two SIM cards, the B7722 has been designed with travelers in mind. One of the SIM cards is connected to a 3G network, while the other one is connected to a GSM network.

           Here's how you can take advantage of the dual-SIM Samsung B7722 when you travel. Keep your home network SIM card in the 3G slot so that you can enjoy fast data download rates when you're in your home country. If you want to save lots of money, don't make phone calls or access the Internet from this phone number when you travel. If you answer calls to this number when you are overseas, be careful, because you have to pay roaming fees.

              When you travel, get a local pre-paid SIM card. Insert the local SIM card into the GSM/GPRS slot. Always use this number when you need to dial someone. You probably won't get many phone calls to this number because no one is aware of it - unless you let your closest friends and family know about it. Also, use only this phone number for email or Internet access (if the pre-paid card includes data access, which they often don't have).

The Samsung B7722 comes with 3.2-inch touch screen. The phone is powered by Samsung's own TouchWiz software, Wi-Fi, FM radio, and 5 megapixel camera. List price for the phone is 429 euros.
