The suggestion that such advertisements are true or false is to call local 10086 to verify the most accurate. This port is 10086, which has certain credibility, but it needs to be optimistic about some requirements, such as at least how long it will be online and fixed monthly consumption. If it is not suitable for use, don't be greedy for this petty gain. Because some network access contracts that are not in line with their habits may lead to a lot of meaningless expenses.
