How to open international SMS reminder on mobile phone

This happened to my mobile phone. I asked the customer service and said that I didn't open international business and I couldn't see it.

If the signal in your place is unstable, the network is temporarily missing, or affected by other aspects (magnetic field, tunnel, or other network blind areas), this situation will also occur in some closed places (elevators, subways, underground garages, toilets), which may also lead to the temporary unavailability or delay of SMS. In another case, due to the network settings, if the access point is not set correctly, the multimedia message cannot be received. Most of users' questions focus on Android models. Although there are many settings on the Internet, most of them still can't be used normally. Here we introduce you to a relatively simple and very practical method.

Solution:

Mobile phone settings-wireless and network settings-mobile network-access point name. After entering the name of the access point, if it is empty, you can click the menu button and select New APN, and then a new interface will appear. Fill in the name (name) and the APN option is "cmnet", regardless of other options, and then click the menu to select Save. After all the above steps are completed, you will find that there is an access point of cmnet in the access point. Just choose it. At this time, you will find "E" and two small arrows in the notification bar, indicating that the network connection has been set up successfully.
