MMS and SMS are not working properly on my iPhone5s. I've had trouble receiving group messages for the last eight days. Phone randomly dumps a bunch of backlogged messages at random times.
I'd like to know what settings will allow me to get messages that have been sent to me but do not show up on my iMessage group texts. It looks like messages I send out are being received but their replies do not show up on my phone.
iPhone 5s, iOS 12
