So I've had a Thunderbolt since day 1 and happened to lose it a few months back. I went to a Verizon store and they replaced it with a fee since I had insurance. Just last night I found the original phone, some how it fell behind a storage bin in my garage. Since I reported the phone as lost, do I have to return this phone to Verizon? I'd like to just throw another sim into it since I have another contracted sim card and just use it as a tether device for work. I'd hate to have any issues with my plan for them thinking I scammed the system or something to get a second phone. Thoughts?
