Everything works fine on the PC, sends ajax requests, processes using php, everything is as it should be, but if you access it from the phone, it gives an error 400, although everything is fine on the PC, as it is maybe at all?

here is the request code

$('.btn-modal').click(()=> {

        const name = $('input[name=name]').val();
        const email = $('input[name=email]');
        const checkbox = $('input[name=trueorfalse]');
        const emailVal = $(email).val();
        const str = 'action=impact&name=' + name + '&email=' + emailVal;
        if(!validateEmail(emailVal)) {
            return false;
        } else if(!$(checkbox).is(':checked')) {
            return false;
        } else {
            $.ajax({
                url: admin_url,
                type: 'post',
                data: str,
