Mobile Service drops to 0 bars /x, reboot sometimes fixes Zenphone 9 Android 14

[JTWAYT]

Zenfone 9, Android 14 Patch level April 5, 2024
FW version WW_34.0304.2004.108
Provider T-Mobile

Since about April 28, I've noticed cell signal cuts out completely with 0 bars and a little x on the icon. I have moderate signal at home. I'm traveling in Houston and can see cell towers along the highway. Sometimes I can power cycle the phone and it re-acquires signal. This morning I tried 3 times with no improvement. 2 hours later, it has 2 bars.

What should I try?
