You need to change <xsl:for-each select= "database/sims/sim[simID = $callsimID]"> to <xsl:for-each select= "/database/sims/sim[simID = $callsimID]"> to make sure you select the sim elements down from the document node / .
I would however define a key <xsl:key name="sim" match="sims/sim" use="simID"/> and use <xsl:for-each select="key('sim', $callsimID)"> , that should be more efficient.

This is pretty straightforward and you don't need <xsl:for-each> at all. Also, you really should modularize your stylesheet.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html>
<head>
<title>Customers</title>
</head>
<body>
<xsl:apply-templates select="database" />
</body>
</html>
</xsl:template>
<xsl:template match="database">
<table rules="all">
<caption>Customers</caption>
<xsl:apply-templates select="
sims/sim[
simID = current()/calls/call[
countryCodeOfOtherParty = '49'
and areaCodeOfOtherParty = '31'
and numberCodeOfOtherParty ='124567'
]/simID
]
" />
</table>
</xsl:template>
<xsl:template match="sim">
<tr>
<td><xsl:value-of select="customerID" /></td>
</tr>
</xsl:template>
</xsl:stylesheet>
where
sims/sim[
simID = current()/calls/call[
countryCodeOfOtherParty = '49'
and areaCodeOfOtherParty = '31'
and numberCodeOfOtherParty ='124567'
]/simID
]
unsurprisingly means "every SIM that has a call to that particular number" . Note the use of the current() function to reference the <database> in mid-XPath.
You can improve performance by using an <xsl:key> , but in the end that's only necessary if your <database> is very large and the stylesheet becomes sluggish.
