on the online bookings can you specify mobile number as the text system will send to a land line .

possibly ask for both mobile and home number with the texts being sent to the mobile number

Hi a1lux,
if you have set up Clickatell then under the phone number there will be a check mark that the customer has to click if they require SMS notification and they would not check it if they use a land line. Also Clickatell should not be sending SMS to land lines.

We do not see the need to add 2 fields and complicate the form further.

Please give us more details of your observations and how did this come to your attention.

Kind regards.
