As I mentioned in a recent post, I am teaching a course in educational technology in Uzbekistan. My university has very limited WiFi access (there is campus-wide WiFi, but only to access specific university-approved websites). I was considering purchasing a mobile WiFi router in order for me and my students to be able to access apps, websites, etc. in class. The only problem is that the monthly data costs might be prohibitively expensive for the Uzbek teachers in my module. Does anyone else have any other ideas?
