I changed my sim card and now im locked out and I cannot remember the password…i didnt think i'd ever use it. The online instructions are useless since I cannot even get to any settings or the app since my phone is…well…LOCKED!!! No support since this is a trial. Thank God It is because I'd be pissed if I wasted money on this dumb thing! I will NEVER buy!
