China Mobile has not used up its mobile phone traffic this month. Can you transfer it to next month? Are there any restrictions?

From 20 15 to 10, the remaining traffic in the current month's package can be carried forward to next month by default for qualified systems, and the carried-forward traffic will be invalid before the end of the next month. Enjoy unclear packages: basic tariff package with traffic, monthly package with traffic, leisure (night) package, TD package, MIFI(4G traffic package), happy traffic annual package and so on. Such as tariff transformation, traffic package change, account cancellation, port number transfer, etc. , the remaining traffic of the original package does not enjoy this service. In addition, if there are open air packages, quadruple music (triple guarantee), automatic upshift packages, quarterly/semi-annual packages, holiday traffic packages, preferential traffic, Internet cards, CPE, MIFI (non-4G traffic packages), daily traffic packages/hourly traffic packages, and traffic premium packages, you can still enjoy the service of "traffic is not cleared in the current month" after switching to the network.
