I think that wouldn't be 'too' complecated to do and it would improve code readability and shortness code, to have 

    @Override
    public boolean equals(Object obj) {
        if (obj == null) {
            return false;
        }
        if (getClass() != obj.getClass()) {
            return false;
        }
        final MobileProductDetails other = (MobileProductDetails) obj;
        return new EqualsBuilder().
            append(this.getMsisdn(), other.getMsisdn()).
            append(this.getImsi(), other.getImsi()).isEquals();
    }

instead of 

    @Override
    public boolean equals(Object obj) {
        if (obj == null) {
            return false;
        }
        if (getClass() != obj.getClass()) {
            return false;
        }
        final MobileProductDetails other = (MobileProductDetails) obj;
        if (!Objects.equals(this.msisdn, other.msisdn)) {
            return false;
        }
        if (!Objects.equals(this.imsi, other.imsi)) {
            return false;
        }
        return true;
    }

Especially if the rest of the code in the modules only uses EqualsBuilder... which NB does not suppert yet :)
