Sprint Denies Report of Unlocked Micro-SIM in iPhone 4S

Yesterday, Macworld reported that Sprint would be selling the iPhone 4S with an unlocked micro-SIM slot, potentially allowing users traveling abroad to simply slip in a local micro-SIM card and avoid high roaming costs.

Ars Technica now reports that Sprint has reached out to deny this report, indicating that the iPhone 4S will not work with international micro-SIMs.

However, while Sprint will now support international roaming on GSM networks with the appropriate monthly plan, the company will not be selling the phone unlocked for use with international microSIMs. Ars asked Michelle Mermelstein, a Sprint wireless device public relations representative, to confirm that the Sprint iPhone 4S would not work with international microSIMs. “That is correct,” Mermelstein said. “I believe Verizon’s device works the same way.”

Sprint customer service agents have also been offering similar information in response to questions about international travel with the iPhone 4S.

iPhone 4S has World Mode Capabilities with the pre-inserted SIM card. However, you will not be able to use non-Sprint SIM card with it, due to technology differences. If you purchase iPhone 4S you will be able to use it internationally with Sprint Services.

Note: International capabilities will be locked and you will have to call Sprint to activate.

The iPhone 4S, officially set to launch on Friday, is a world-mode device capable of supporting both GSM and CDMA networks, but carrier locking and other requirements will substantially limit that flexibility for customers purchasing subsidized versions of the device.

Sprint, you let me down

I am a TMobile customer currently using an original 2G iPhone jail broken. I am going to be in a line on Friday buying an iPhone. I would have bought it from you, or who ever will have an unlocked international SIM slot. I guess as no one does, I will go with AT&T for the HSPDA+

Sorry Sprint, short sightedness just lost you a customer.

A contract is a contract, and I understand to get a subsidized phone I will need to be locked into a plan for two years. Why you can't just let me do what I want to with my phone (impacting your data network in no way) as long as my monthly check to you rolls in, I have no idea.

Annoyed.

What a load of horse crap. I guess the best bet is to just buy the factory unlocked iPhone and use it with AT&T in the US and anyone else outside the country.

It seems you cannot use the factory unlocked on the CDMA networks.

AT&T wins I guess.

It's time the US actually protect the consumer for once and pass a law to get rid of this locking crap. It's your phone, you should be able to use it where you want. They all ready penalize you when you leave early to recoup the subsidy. Cell phones in the US are ridiculously overpriced.

Well that's a let down.. I'm out of the country about 30% of the year. That feature alone would have got me to switch from ATT to Sprint!

Best of both worlds! Unlimited Data at home and freedom when abroad...

That's too bad! Sprint if you ever see this there are a lot of business customers who travel internationally that would love to have a feature like that!

@19.95 per megabyte abroad with ATT I usually just turn my iPhone off and use a cheap local burner or Skype.
