Can I put a prepaid phones sim card into a unlocked iphone?

So like a prepaid phone from walmart with a 15-30$ a month cost for each card or something like that, could I put that sim card into a Unlocked iPhone and only need to pay 15 or so dollars a month?
(of course after buying the 900$ iphone and all that.)

Yah. Lol

You can sure put a prepaid simcard into an unlocked iphone. But if you want your iphone to accept that simcard, make sure it can be used in an unlocked phone.

  • Should I put my metroPCS 25$ sim card into an unlocked iphone? I got this metroPCS 25$ plan. They gave me a very bad (unlocked/sim card) phone with a sim card inside it. Second day, i put this sim card into another phone that was unlocked, called it and it worked. I'm planning on buying an unlocked iphone to take out my sim card out of my bad phone and put it inside the iphone. Please tell me if it is gonna work? Will i have problems with metroPCS? Will it work on other unlocked smartphones and so on.
  • If I put a SIM card into an unlocked iPhone will it lock it to that phone? I recently received an unlocked iPhone 5s as a replacement from LifeProof. The point is, it says ATT unlocked. It says SIM required when I turn on the phone. I have a sim card but it's from my current service which I'm going to cancel so I don't know if there's a way to bypass the sim required. Or if I use my current sim card will I no longer be able to use another one?
  • I put my old phones sim into iphone 3? I had a motarola phone, and was on a contract and had all the things like 3g, texts, minuets.

  • Can you put a T-Mobile micro sim card into an unlocked iphone 4s? My brother recently gave me his iPhone 4s since he got the new iPhone 5, so I can't make calls, or text, or get on the internet (unless I have Wi-Fi). I found my way into the sim card slot for the iPhone, but my MyTouch 4G sim card is too big.Me and my Mom are going to go the T-Mobile store to get a micro sim card so I can transfer my data onto it, so I can put it in the iPhone. Will it work?
