    I have a 3G ATT SIM from a work device. If I cut it down to nano SIM size, will it work in an iPhone 6 (at 3G speeds, obviously)? Or is an LTE SIM required? Thanks.

    it is my understanding that as long as its orange it will work

    you really should have work just give you a different sim or switch your sim

    i wouldn't cut the sim unless i was desperate.

    if work gives you a basic messaging phone and you stick the sim in an iPhone with cellular data turned on, they might get mad

    as far as 3g goes, it won't matter i think, as far as i know the phone will connect at 4g/lte speeds regardless of the sim. except when it comes to cricket and they slow your speed down
