I came across the following user developed article explaining the several reasons for WAN02 and 05 error codes: https://networkbuildz.com/fix-t-mobile-home-internet-error-codes-wan002-wan005-and-cel002/
About ½ through the article the author explains a few steps on how to overcome the errors including unplug and restart the gateway, remove and reinsert the SIM card (or go to the local T-Mobile store and ask for a replacement SIM card - it could be defective), or do a device reset.
Let us know what fixes your problem.
The T-Mobile 5G internet worked good for 6 months, then started randomly breaking connection and displaying error code WAN002. They tested the home unit remotely and told me to go to the nearest T-Mobile store to have a new SIM card installed. After I returned home with the newly installed SIM card in the Router, the WAN002 code started again after a half hour of use. The next tech said it was a cell tower issue. After waiting 5 days for them to check the cell towers in my area the code went away. Have T-Mobile run checks on the cell towers in your area if the SIM card does not resolve the issue.
