    Unlocked T-Mobile Samsung Galaxy S3 on AT&T Network?

    I have 4 t-mobile samsung galaxy s3 currently on T-mobile. I will need to switch over to AT&T later this year, and am wondering if I unlock these SGH-T999 phones and use them on the AT&T network will everything work correctly? If not which differences would I encounter? Would it just be wise to sell the phones and just purchase the AT&T SGH-I747?

    If you can get them unlocked then the Tmobile version will work fine with the exception of LTE. You will have 3G/HSPA+ but it certainly won't be as fast as Tmobiles. If LTE is a must then your only option is the ATT model.

    You can get T-Mobile to unlock them or buy unlock codes on eBay for a few dollars each.

    I would sell them and buy the AT&T version of the S III or something equivalent to that.
