Subject: Android 17 Beta 5 - eSIM Network Connection Issue & Invalid MMI Code
After updating my Pixel 7a to the Android 17 QPR1 Beta 5, I am completely unable to use USSD/MMI codes on my new Vodacom eSIM. Every time I try to dial a shortcode (e.g., 14901#) to buy bundles or check my balance, I get a "Connection problem or invalid MMI code" error.
My carrier (Vodacom Tanzania) has confirmed that my eSIM profile and network status are perfectly fine on their end. The eSIM data works, but USSD codes fail completely. I have already tried resetting network settings, toggling Airplane mode, and restarting the SIM, but nothing works. This seems to be a modem/eSIM bug specific to this beta build. Please fix this in the next update. Thanks!
