My little 6 year old is desperate to get a smart phone cause he saw it in one of his friend's wrist at school. So got him a Padzene Dz09. But now I need a sim to put in it. What is the cheapest deal on a sim only plan you guys recommend ? I am scared that is is going to call me and leave the call on, so I hope that me cutting his call from my side will do the job. But to make sure that he doesn't burn my pocket, looking for sim only plans that have unlimited text and sms facility. Hopefully a 5 GB Internet will come in handy. Kindly advise.
