This is better than most phone shops in the plaza as it is not restricted to one service provider.
They help you choose the plan that best suits you, explain the phones and their features.
They're also willing to help you with any issues you encounter.

Great range of products and good prices. The staff at the TTP AllPhones do what they can to help you (ie help choose a plan, the right phone for you etc). The don't just sell for one service provider, so there is more choice.
