If you haven't heard much from your students, my iphone, which I had planned to use as a wireless hotspot, is not allowing other devices to connect. This means that students can write using my phone, but can't connect with their own devices. If you've had radio silence from your student, this might be why.
Also, tomorrow we're heading to Ruaha National Park, a protected area the size of Belgium. I'm not sure what mobile coverage is like out there. If you have an emergency and can't get through to my phone, you might also try to call San Moyer, who will be able to get in touch with us via our lodges or HF radio. Dan's number is: +255 687 107 730
