Why did I receive your message to open 2 1M internet service, and then there was no network? . .

This may happen because your phone bill balance is insufficient, or because the traffic you used last month exceeded the traffic cap value, which caused the Internet access function to be temporarily closed. I suggest you check whether your number is working properly and see if your mobile phone needs recharging.

Opening 2 1M internet access function will not only improve the internet speed, but also will not affect the use of your mobile phone itself, and generally will not lead to no internet.
