I have a T-Mobile prepaid sim card and I was wondering if anyone had the experience of buying an unlocked Samsung Galaxy S3 and using the prepaid sim card?

Does it work fine? Is there any issues with it?

My main reason to stick with unlocked is to avoid lag in the firmware updates which occur in locked phones due to reluctant carriers. Also if I decide to flash and experiment with my phone I would not be breaking in contracts.

If "unlocked" means "no SIM lock", I don't see why it should not work. – Izzy Sep 30 '12 at 13:02
Well a lot of Carriers have issues when it comes to Quad core as the US mobile carriers do not support them. – Sam007 Sep 30 '12 at 17:07
You see me confused: What has the number of cores to do with the SIM, or with the telephony function as such? That's as if a highway would not support cars with quad (all-wheel power). – Izzy Sep 30 '12 at 18:53
Seems you are not aware about issue with the cores in US telecomm carriers. Here's a brief description, wired.com/gadgetlab/2012/06/…, of what is the effect of cores on the Carriers and why Samsung Galaxy S3 is dual core and not quad core in US. – Sam007 Sep 30 '12 at 20:43
No, I'm not involved in crazy politics, patent wars, and the like xD Honestly: It's the carriers decision which phones they sell (and that's what the linked article is about). But if you got the phone somewhere else, they surely won't send someone after you to have a look inside your phone and count the cores, RAM, and the like. To them, the SIM card counts. To the phone, the SIM lock may count to recognize the card. That's all in this context. – Izzy Sep 30 '12 at 20:52

If the mobile is unlocked, then you can use any SIM card. There won't be any problems.
