    Jotform & Twilio using Zapier - Hidden Default Value in a field

    Asked by thespanishfactory on November 27, 2013 at 02:02 PM

    Hi guys.

    I am using Zapier to send SMS notifications based on form responses. There is however an issue.

    ERROR: The 'To' number +07X XXXXXXXX is not a valid phone number.


    I have tested some ways to fix this and it could be work if i could add "44" (uk international code) before that the user enter the mobile number in this format 07X XXXXXXXX. I can add it using the Default Value tool but this is not what i am looking for. I want this "44" value hidden for the user, adding by default.

    There is any way I could do this? I cant use iframes as the our page it is responsive, so we are using ----


    Many thanks!

    Ok I fix it ! :)

    You only need to add 44 in Zapier:

    To Number (required)  

    Required number format: 15554443333 or 44111222333. Can send to multiple numbers with commas: 15554443333,44111222333

    44Fields Mobile Number
