"Will this aHappyDeal.com Cell Phone work in my country?"
Whether a mobile phone you buy from aHappyDeal.com is compatible or not depends on whether the supported GSM frequencies of the phone match the frequency of your cell network.
Luckily there are only four GSM frequencies. You simply need to find out the GSM frequencies supported under your current SIM card cellular provider. After that, you simply match it to the GSM specification of your chosen aHappyDeal.com mobile phone.
