I borrowed a Samsung Galaxy S device in order to test an app. I have attempted to insert my iPhone 4 sim card (micro-SIM) into the Galaxy S, yet the device won't recognize it and display a 'No SIM' error. Is the Galaxy S compatible with micro-SIM or do I need to purchase a different one?

look up your device specification on GSMArena.com and check if it supports micro-sim or mini-sim. – MAKZ Oct 25 '14 at 16:37

The Samsung Galaxy S (not S2; S3; S4 or S5) uses a mini-SIM. The iPhone 4 uses a micro-SIM. Maybe Robert's answer, well, kind of missed the wood for the trees.

Sadly, most of the SIM card mobile service providers have recently taken to heavy-handed self-protection tactics to retain their market share.
Most carriers have "tweaked" their SIM cards so you generally MUST purchase a SIM card that matches not only the service provider, but also the device configuration for which it was engineered.
While there might be a way to Flash a SIM card, but a new SIM card is so cheap it is not worth it.
Besides, SIM cards must be compatible with the device as well as the carrier.
For example, Simple Mobile is a subsidiary of T-Mobile and they both use SIM cards similar to Verizon's, however, none of these are "fully interoperable" with each other, as Verizon uses a different radio frequency for their LTE/4G or whatever thay are calling it now. Some SIM's from carrier "A" work on carrier "B" but not the other way around...
I am just waiting for a carrier that does not bother to collect my metadata.
If they didn't bother with all that overhead, our service would be dirt cheap...

1Interesting, I've never heard of such a practice, at least here in Germany/Europe. The radio frequency is usually not related to the SIM card at all. – Flow Nov 21 '14 at 22:58
