Can you connect an iphone 4 unlocked from att to boost mobile?

Can you conect a att iphone 4 thats unlocked to boost mobile? With a GSM card? Does the card need to be cut or whatever that is?

No you can't. Boost mobile is a CDMA network and AT&T is a GSM network. CDMA and GSM are 2 different technologies that are incompatible with each other. Boost mobile doesn't even use SIM cards for service, it uses an ESN # that is hard coded into CDMA phones to activate service.

Nope, you can't.

  • Unlocked att iphone on sprint/boost? I need some help. My mother has an iphone 5s 16 gb white that she's willing to give to me only if i can unlock it. If she cancels her plan (she's not on contract) i can jailbreak it and unlock it. Then with the unlocked iphone would i be able to take it into boostmobile and connect it as my daily phone? I currently have a lg f7 and how would i go about removing that phone from my plan and connecting the iphone?
  • If I buy an unlocked ATT iPhone 4S can I use it for boost? There's an iPhone 4S on eBay that's been unlocked, so I was wondering if now that Boost Mobile sells the iPhone if I would be able to switch the old ATT phone to boost mobile?
  • If I buy an iphone (not from the boost mobile store) can I connect it to boost mobile? Lets say I buy an iphone that isn't connect, will I be able to get it within the boost mobile network? Or is their more to it
  • Can I use the new unlocked iphone 5s on boost mobile? I'm getting the Iphone5s when I get to the US in a couple of weeks time. (Basically, I need an unlocked phone so I can use it in a years time when I get back to the UK.) Looking at the cheapest sims in the US. Boost monthly paid sim looks like one of the cheapest deals. Will a boost sim work on an unlocked Iphone 5s. (I have seen answers for a similar question but from over 5 years ago saying no but for a different Iphone model.)
