T-Mobile Customers Can Finally Use the iPhone 4

If T-Mobile just so happens to be your network of choice, then there are two things you would probably like to know: T-Mobile customers can now use iPhone 4 on its network and hey, that network choice will be gone post AT&T merge anyway so it may be better on your wallet to just go with a subsidized iPhone 4 from AT&T rather than using the simple workaround T-Mobile finally devised involving a full-price, unlocked version of the same phone that costs 2-3 times more.

Micro SIM Cards, which the iPhone 4 and a short list of other smartphones utilize, can now be purchased in a T-Mobile retail store (I was unaware that those still existed…) for $9.99 and online for free. Both required a two-year data plan commitment. A user can then place the Micro SIM Card inside of an unlocked iPhone 4 to receive full T-Mobile service. An unlocked, meaning that it is open for other GSM carriers, iPhone 4 would have to be purchased from AT&T at a price of $649 or $749 for the 16GB and 32GB models respectively.

With the limited adoption of Micro SIM cards, this is obviously a move specifically aimed at bringing iPhone users over to the carrier. T-Mobile admits online that that is indeed the case, ”Already have a GSM phone or iPhone that you need to activate – or have an unlocked GSM phone you want to use on the T-Mobile network? Just get a Micro SIM card and choose a plan. Slip the ready-to-use Micro SIM card into your phone and you’re ready to go.”

The practice of purchasing an iPhone without AT&T service then unlocking it for T-Mobile usage in areas with shoddy coverage from the former or to receive cheaper data rates has been ongoing since the phone’s early days. Once the latest iteration was released with support exclusively for a smaller type of SIM card, there was a roadblock for T-Mobile customers to upgrade. After over a year, T-Mobile can finally support Apple’s latest-and-greatest – wait, can it still be called that?

Welcome to last year, anybody who is ready to hop on board with the iPhone 4 on T-Mobile. On the bright side, this likely means that the next iPhone rumored to launch in fall will work on T-Mobile from day one.
