T AT&T Options Ahead of Earnings

If you haven`t sold T AT&T here:

Then analyzing the options chain of T AT&T prior to the earnings report this week, I would consider purchasing
Calls with a 20usd strike price and an expiration date of 2023-4-21, for a premium of approximately $0.38.
If these options prove to be profitable prior to the earnings release, I would sell at least half of them.

I am interested to hear your thoughts on this strategy.
