I'm sorry to hear that you're having so much trouble with crashes, and making and receiving calls. The network doesn't cause crashes so this may be an issue with the phone itself. You may wish to check <A href="https://www.samsung.com/uk/support/" target="_self">Samsung's online support</A>, and they can assess if the phone needs a repair, or if they can fix this over a call or chat.</P> <P>The issue with calls may or may not be linked. Are you able to test your Three SIM in any other phone to see if the call issues are only on your S22 Ultra?</P> <P>JonathanB</P> Thu, 30 Jun 2022 10:11:39 GMT JonathanB 2022-06-30T10:11:39Z https://community.three.co.uk/t5/Devices/Samsung-or-three/m-p/1892#M190 <P>Samsung s22 ultra keep on crashing need to restart.
