Mobile Number In Form

[lazysheepmedia]

Good morning

Is there a way to make sure that a user puts a mobile number into a form in the right format. I have built a form to create AcySMS receivers (users) but I need to make sure the mobile is in the right format -

For example the mobile number that is put in should be +447345678901 and not 07345678901

Thanks

Mark
