babum wroteAvok. for the $9 it is the same system but you get less SMS, MB and minutes (You still get the 1 number unlimited). as for how it is payed I think it is just like when you subscribe to any service (Such as BB) you recharge monthly and from that you pay. No idea if you need a different card though.
Solo - I dont think you can, Im almost sure you can't
Both the 9$ and the 17$ plans have the same number of free sms 200.
The way this plan is renewed is that you should buy a 9$ card fill youraccount with it then you can rwnew your plan, in other words te plan is renewed with credits from your line balance, I think that is right, avok ypu can always check the link i included in my first post.
