There are always plenty of good reasons to upgrade and choose from one of our big brand mobile phones. Customers often ask us Android or IOS, what is the difference ? Android is an open source operating system while iOS is a closed operating system with some open source components. Android operating system can be declared as universal operating system as it is for mostly all kinds of smartphones except Apple hardware. While iOS is restricted to Apple devices only. So whatever your preference, Mammoth phones can meet your needs !
