Downloaded the whole manual for Mavic Mini , been flying 3 days only and now realise manual says mobile data should be turned on, must have missed it in tiny booklet you get with Mini ? No problems flying without mobile data up to 350 feet and good distance away . I admit I am a stupid old git - how vital is mobile data? Again being an oldie I'm not on social media every minute of my life and have a small monthly data package, help/advice appreciated . Thanks Barrie
