The key to this is when did you obtain the credit cards? You also referenced being deployed and not activated.
If you were already in military service when you obtained the credit cards and you are being deployed, or re-deployed, you are not eligible for relief under the SCRA.
However, if you are being activated, such as a Reserve call up, then Beagles22 comments will apply.
