For the last few days, some - not all - SMS messages sent to my phone have not arrived. This occurs with services - .e.g. GiffGaff (I am on GiffGaff) - that send SMSs as TFA, except that when I tell such a service to resend the text, then I receive it. Also, a few messages from friends have gone missing. Can anyone help me to solve this problem?
I have a Zenfone 8. It has Android 12 and the latest release of the firmware. It is not rooted. The type of signal that I am on is (mostly) 4G.
I do not think that my SMS application, which is Textra, is to blame. (For, I could no see the missing messages in the stock SMS app, namely, the one called 'Messages'.)
