One problem is that the signal strength rarely reaches the 3G signal (the blue light in the modem device) so the Internet connection speed is too slow and it takes me several minutes to navigate on a regular website. Also, the signal often fails, which is another problem.
Iíve been dealing with these two problems and I consider the service almost useless. I have checked the 3g coverage and the city where I live is on the list.
Something must be done to correct these problems; otherwise I must cancel my subscription.
