Tell me please why the defence discount services code doesnt work with new phone and airtime. And ive checked, new phone not on the unvalid list. Who can fix this. thx

S20+, my 2nd keeps resetting when you are on certain apps and when its plugged in charging. This is the 2nd phone as the last one did exactly the same {also the s20+}. Its no use to me so can you fix or is it going back. Also cannot use google as it ...
