I'm not sure if I understand what you mean, but if it's like I assume it is, then you should have some options.
If you don't, then sucks to be you.
Number checkups are very easy in Sweden, just enter the number and you'll get the name.
Except if they have personally gone into these pages and confirmed that they don't want to be a part of the list.
You normally get added to these lists when you get a new number.
A cell phone number probably not. You might be lucky and find it on a person searching site like Spokeo. Paying premium is never worth it as the numbers are often invalid or changed. Your best bet would be to card a subscription so you don't waste your money.
