I am using this mts product since 3 months, this is a very usefull dongle. It has nice 3g speed in my area and even my friends are satisfied in different areas. I am using postpaid connection, the bill is clear and transparent. No hifden charges and fixed monthly charges. The product is good and durabke too. The coverage is nice and the speed almost doubles during night time. May be because of less consumers during night. Once I connect it, the connection never drops. It is continuously connected to the network. I love mts.
