Cant send or receive calls

[SpinyNorman]

Been fine with Smarty for months then at some point in the last week I've been unable to make or receive calls. Had this before with a porting issue last year which Smarty kindly fixed.

Tried sim in another phone and no change.

Samsung s10.

This is likely due to Smarty's parent network Three switching off 3G in your area. The S10 is not on Smarty's list of incompatible devices (see here) so can you see an option for switching on VoLTE (4G calling) anywhere in your phone settings?

All I have is lte/3g/2g which is already selected.

@NigelTy_1746721  But have you checked that it is on the compatible list?
