What does it mean for telecom internet access to drop to 1Mbps?

It means that your internet speed is limited. 1Mbps is the network speed of 128k/s, which is already very slow in the 4G era.

Generally speaking, when the traffic reaches a certain level, mobile operators will limit the speed of surfing the Internet. See the package regulations of the card for the specific traffic speed limit. You can ask the telecom customer service to see if there is any relevant agreement in your package agreement.

Regulations of three major communication operators on traffic speed limit:

1, China Mobile's unlimited package, will give you a speed limit directly when the usage exceeds 20G. When it can still be used at the network speed of 1Mbps, after capping with 100GB, the traffic will be turned off this month and re-enabled next month.

2. The "Speed Limit Description" of China Unicom's unlimited package of Shen Bing Card clearly states that after the usage reaches 40GB, the Internet access will be reduced to 7.2Mbps Of course, if you are a small Shen Bing card, the 20G network speed will only be 1Mbps.

3. China Telecom's unlimited package. After the Internet traffic reaches 20GB in the current month, the Internet access rate reaches 1Mbps, and it will resume normal use next month.
