iphone messages truncating php mailer email

Question

I have a website that uses php mailer to send form input to a phone using the Verizon service. The issue is that the online form is being sent to a phone via text using the PHP mailer.

On the Android phones, the email is received properly and displayed in its entirety as a text message.

On an iPhone, the email is received as a text message, but it's truncated and only a portion is displayed. Notice that it stops at 'Cu.' It supposed to have about eight more lines of information pertaining to the appointment schedule. I'm wondering if iPhone has a character limit shorter than Android phones.

Anyone know how to avoid the text from being truncated on the iPhone?

I've googled for information, but all I get is how to fix the native iPhone email client. Which, isn't the issue.

Thank you.

It's pretty straight forward. The code pulls the form variables and assigns them as variable variables to the $message variable in a foreach loop.

<pre>
    if ($OK_customers && $OK_appointments && $OK_customers_appointment) {
    $message = '';
    $selected_appt_day = date('l', strtotime($appt_date));
    $selected_appt_date = date('m-d-Y', strtotime($appt_date));
    $message .= "\r\n: ".$selected_appt_day.", ".$selected_appt_date."\r\n\r\n";
    $message .= "Please confirm:\r\n\r\n";

    foreach ($expected as $item) {
        if (isset(${$item}) && !empty(${$item})) {
            $val = ${$item};
        }else  {
            $val = 'Not Selected';
        }
        if (is_array($val)) {
            $val = implode(', ', $val);
        }

        $item = str_replace(['_', '-'], ' ', $item);
        $message .= ucfirst($item) . ": $val\r\n";          
    }

    $message = wordwrap($message, 70);
    $mailSent = mail($to, $subject, $message, $headers);
    if (!$mailSent) {
        $errors['mailfail'] = true;
    }
}
</pre>
