would really appreciate help pls I'm having trouble with my galaxy note s10 + so I'm getting the message 'error while searching for networks' ,emergency calls only and eventually when it does give a list of networks when selecting mine it briefly states registering, then showd unable to connect try again later' although very occasionally ill notice a couple of my messages get delivered and the 3 symbol for the network appears this is literally for 2 mins max before emergency calls only shows. Also I'm getting a black triangle with exclamation mark inside with the letters MM underneath, this shows on the status bar in the top left corner, it doesn't remain on the screen it disappears soon after, when scrolled down it suggests 'phone not allowed for voice' I've tried all the possible methods on YouTube apart from the video of a lunatic prizing the back of his phone and poking and prodding the motherboard (not sure if that's the right name) with a screw driver, well instantly knew that I was çertainly not trying that so no idea of the outcome. Must admit I was rather disheartened to hear one you tuber finish his video after going through the different methods to solve network issues, his final words quite abruptly "the phones blocked " and that was the end of the vid. Surely not? Especially as I've had the 3 symbol showing and messages was sent( although this only happened probably 3 separate occasions, can anybody at all shed any light please, I will also mention the signal shows as though its full this hadn't altered. Thankyou in advance
