vodafone will be the best choice for your kid.
you have to recharge 20qr in two months. so total 120qr per year, as she will not call that much.
its the best because you don;t have to think about extending validity every month like QTEL.
but the money which you recharge must have to finish within 2 months or not it will disappear. i think its easy to finish 20qr in two months.
so go for vodafone red. buy a sim card and 20qr recharge card. thats it!!!
enjoy and keep in touch with your kid where and when ever she is!@!
