I used huawei pocket wifi with $90 plan (25gb), and today I bought Huawei wifi cube 4g. When i bought that cube, they gave me a prepaid sim which is free (6gb). After i was back home, i set up the cube and checked the internet speed. The speed was amazing. download speed 25.39~31.45 mbps : upload 20.85~33.50. However, my old sim which is $90 plan internet speed is download 4~7mbps : upload 2~3 mbps. i checked them in same place(my home) and with same device(huawei wifi cube 4g). I really do not know why my old sim internet speed too slow. please help me out....
