Here's an idea :

	When you generate the HTML, when IMEI is needed, generate a text box
:
<input type=3D"text" name=3D"IMEIxx" value=3D"">

	When IMEI is not needed, generate a hidden field :
<input type=3D"hidden" name=3D"IMEIxx" value=3D"noIMEI">

	In this way, you're sure that things are symmetrical.  The "xx" is
the label for your nth mobile.  This label has to be generated by ASP.  
So
when you want to validate your field, go through all IMEIxx and check 
if any
of them is empty or contains string of wrong format.

	Since the hidden IMEIxx fields can't be changed by users and its
value isn't empty string, you can be sure that this field passes safely
through validation.

PS: I don't understand what you meant by "combobox".
