Yes. They should do it. Cell phone companies need to simplify charges. Now it is almost like a puzzle to understand how much it costs to make a phone call. There is a prize for the phone. Then another one for the sim card. Then comes service charge. And finally top up minutes. In USA and all, you just sign up for the service and decide the plan you want like $29, $39, $49 etc. whatever you plan to have and you get the service and phone and sim for free. You pay the chosen amount $29, $39, $49 etc.(only one of them

) at the end of the month when you receive the bill. No other charge at all.
