In todays world this type of gadget is useless . 3g supportis worth of zero comparing of ram u can buy some smrtphone in place of it with 3 gb ram and better 4g support .
This big thing cannot even fitin your pocket buy something else in place of this.
no service at all you have to go to a 3 rd party store for itsreplace ment of battery. Not more than 1 hour backup of 2 hour charge.
