I am thinking of buying the following phone in order to be able to use it in countries listed in the subject line. Advertisement claims that it will work in all of Asia but I have no way of knowing for sure based on the stats provided. Here are some questions directly aimed at people living in Dubai (surrounding cities), Saudi Arabia, and Pakistan: Are all phones there designed around GSM technology? Because this phone also uses a SIM chip, will replacing the chip I use in USA with one in either of those country the only requirement to have the phone operating fully?
Please take a minute to read the details in the link provided so that answers to my questions can be given in detail.
Thanks.
