Try some other sim card(also another provider) that work in other phones.Try to go settings/network and select GSM only.If always "inactive sim" then take it to some repair shop.It can be hardware problem but also blocked phone from network.

Thanks for replying. Ive tried other sims and just set GSM only but still inactive sim. Any other methods worth trying before taking it to a shop?
