Hi, I'm super interested in the GPS tracking feature, particularly after the bike has been stolen. As I'm sure you know, not only will the bike need a GPS chip to get its lat/long, it will need a cellular module to send that information to the cloud where we can read it on the Nireeka app. My question is: here in the US what cellular carriers will the bike be compatible with? Is there an estimate of what the monthly cost for this cellular service will be? Given the affordability of the Nireeka bike, I assume a lesser priced 3G cellular chip is being used? What happens at the end of 2019 when all the carriers end their 3G networks?
