The message text should say. > You have requested a replacement sim card. To proceed with the replacement now, reply "Yes". To keep this sim card, reply "No". If you do not reply, a replacement will be mailed to your billing address: 54 Wolverton Gardens in 7 days, and this sim will be deactivated. An attacker now has to overcome the time delay, and the fact that the replacement sim card must be mailed to the billing address. For those people who have an outdated billing address and lose the sim card, require the sim to be offline for 7 days, or demonstrate access to an email address or credit card on the account.
