I would like to know: 1. does it come with an adapter for nano-SIM? 2. the sim is under the battery. is it easy to remove the sim from the M7650 or do you need tweezers or something ? i often need to slide the sim in and out because i also use it with another router or phone. I will be able to remove the sim from the M7650 quickly and easily or every time will be a struggle ?
