Can I get an Unlocked iPhone 5C on the T Mobile 30 dollar plan?

So I want to get an IPhone 5C and my parents and I want the cheapest plan out there. So can I buy a T-Mobile sim unlocked IPhone 5C from the Apple Store and then purchase the 30 dollar plan that T Mobile sells at Wal-Mart?

Yes, you can. However, you may also need to order another SIM card for that $30 plan. The card normally costs $10. If you call T-Mobile customer service, ask for a special offer, which costs you only 99 cents.
