Now the communication facilities in the disaster area should be damaged, so the signal may be unstable. Try to be on the roof or the top of the mountain or under the signal transmission tower, so the probability of receiving the signal is higher, and the crowded places also have an impact on the signal. Try to find out if you can find officers and soldiers and borrow satellite phones. This is basically unaffected. In addition, don't worry, I sincerely hope that you can contact your family as soon as possible and report peace! God bless Yaan! !
