T-Mobile USA Begins Offering Micro-SIMs, Targets iPhone Owners

Last month, T-Mobile USA revealed that it had over one million iPhones running on its network, despite not being officially sanctioned by Apple and the handsets not being able to take advantage of 3G data speeds due to differences in the carrier's network standard compared to other GSM networks. T-Mobile customers had also needed to trim down their T-Mobile SIM cards to fit into the iPhone's micro-SIM slot, as the carrier had not yet begun offering the smaller cards.

As noted by App Advice late yesterday, T-Mobile USA has now rolled out micro-SIMs and has specifically targeted iPhone owners on its page promoting the new cards.

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.

T-Mobile is offering the new micro-SIM free of charge with a two-year contract when purchased via the carrier's website.

T-Mobile USA has been rumored for some time to be preparing to offer the iPhone, although AT&T is currently in the process of trying to acquire the carrier. That potential acquisition has received some opposition, however, and regulatory authorities are still examining the proposed deal. But even with an acquisition, AT&T has said that T-Mobile and AT&T will operate somewhat independently for several years as the combined carrier works to integrate its systems, meaning that an iPhone specific to T-Mobile is likely still of interest.

I surely hope nobody signs up for a two year contract for a SIM card.

T-Mobile clientele isnt quite what Apple is looking for.

That is pretty condescending. Not sure what you mean. Maybe Apple is looking for people that can spell, which would eliminate you.

The big reason AT$T wants to acquire TMO is because without them in the game, AT$T and Veri$on will be able to raise prices in lockstep without anyone making them look bad. After this, you can expect V$ to take over Sprint... and then you have a duopoly.

This all but confirms that iPhone 5 will support T-Mobile's 3G.
We can't be too sure about that

My thoughts exactly when I saw that (2 year contract) next to free price.

That has to be of the worst deals ever. I thought this would be prepaid.
