I have a samsung galaxy ace 2 x and i would like to know if i can change to a iphone 4s and keeping the same plan and i pay 30$ every month so is it possible to keep the same plan if i switch to a iphone 4s?
Yes you can keep the same plan. Just make sure you have no remaining negative tab. Since your plan is $30, you have the option of using Tab S or M.
Tab s 150 off
Tab M 300 off but there is a $5 tab charge monthly
All tabs are cleared within 24 months.
