Can I get my old contacts and viber history if I reactivate the sim card I lost?

I lost my iPhone and the sim card, if I reactivate the sim card from the company, and use the card on a different iPhone can I get back the conversation history or contacts?

No. You can store contacts on a SIM, but it's physically resident on that chip, not another one like it.

No, But if you sign in your iCloud on your a different iPhone, there might be chance that all your contacts will be back but the conversation history will not come back.
