No, I would not recommend it.
If you plan to travel overseas, you need a true quadband mobile phone for use on GSM systems. As I read it, this phone can only handle one of two dual bandGSMs that you choose.
In USA, there are many areas only served by Verizon and Sprint which are CDMA systems not GSM.
Just go on ebay and search for 'unlocked quadband GSM mobile phone.'
They can be had new from about $25 and up over $400, depending on how much silliness you want on the phone.
