Thank you everyone for your help! I am glad to tell you that I have downloaded the AddAPN APP from Google Play and it works for me. This one is free. The key is: you have to remove your SIM card before you save the new APN you created.
Thanks everyone for your reply! I note that I can't edit the APN settings. According to the below articles, it seems to me that it won't work because of an Android 8.1 issue. I may need to leave Public Mobile! https://productioncommunity.publicmobi...
