Hi SazzyCo, I would say yes. My son lost his phone a while back and reported it to the company. A few days later a friend found it and gave it back to him but it wouldn't work. He contacted the company and it took them over a week to reconect him. So they must have blocked the phone after he reported it missing. He did get them to send him replacement simcard for him to use while he didn't have his phone ie, put it in another phone, but that wouldn't work in his until they had unblocked it.
