I need to receive SMS via wifi calling at home as the network signal where I live is useless. I don't need any other facilities such as data or voice calls as this will be used solely for receiving OTP's at home. I plan to get a PAYG sim for it. Any suggestions for a cheap handset? I've been looking at older 2nd hand phones for under £40 but it is a nightmare trying to work out whether they can work with wifi calling or which operating systems they will need to run it and even whether they can be upgraded to a recent enough OS or not.
Any suggestions please?
