My Sister did recontract for Samsung Alpha 4G, with this free Samsung Tab 3 7" wifi only.
The model is SM-T110
Mine is without front camera.
The model you link is different model SM-T113.
That SM-T113 is most probably for sale only.
And may not be the same model for free gift.
It is not given together when you purchase the handset.
They will give you the redemption letter to claim for this free gift.
So they may not able to say which model.
Since they did not give together with mobile handset.
