Data and phone transfer issue

[Ray31]

My data will not work. I payed for this plan over a week ago, I have had the SIM card activated for days and my data doesn’t work, I can’t change the APN, and nothing else has worked. I also tried to transfer my phone number 3 separate times and it won’t change.

@Ray31 , what model of phone do you have?  Generally, if your phone is relatively new, the operating system should be able to identify through the SIM card information the APN settings on file in the phone that could work for this service.  User edits of APN settings are not required.  By chance, do you have more than one SIM card in the phone and have set mobile data to a second SIM.
