CbIPStrange, I can ask the software team if they have any kind of limit enabled. Which would be strange, phone calls routinely go that long...
I have just found that every call I make with sim1 drops after exactly 30 minutes (tried 3 times). I don't know if the same situation happens with sim2 (can't check right now). I wonder if it is a setting I can change or some carrier limitation?
Could somebody help me?
Call drops after exactly 30 mins.
