Be on the lookout for charges from SMS Outlet on your America Express charge.

This will probably show up as an internet charge with the company located :

Merchant Number:
1044708386
Merchant Address: 658 MCCORD AVE
BAKERSFIELD, CA 93308-4716 USA

This address shows up on google maps as a single family home.

There is apparently a legitimate company SMS Outlet in Tempe Arizona who state they have had a lot of American Express card holders call with unrecognized charges.

Let's nip this one in the bud!
