Sometimes abusiness trip, when was the business office, or travel, the phone did not
signal a sudden, you feel if suddenly LOW half, then how do we encountered no
signal at the situation?
Smart phone
already has become an indispensable part of our lives, but if no signal that
this phone would immediately become a decoration, can not talk, can not send
text messages, the network will also Rom. The vast majority of cases occur intermittently,
and so will automatically recover a little, but after a while child or if no
signal no service state, that is out of the question, the following will bring
no signal solutions.
You look at the
current location is not in the signal blind area, including those outside the
network coverage blind spots, such as workshops, factories, suburban and rural
areas, yet construction of the network where communications facilities, as well
as city cell phone signal where the signal can not be blocked by the shield
cover, such as offices, bars package, the elevator, underground places,
buildings and other places.
Workaround: out
may not signal venue into a large place to call.
If the position is not the issue it may be
caused by interference facilities, cell phone signal is received through
propagation of electromagnetic waves, radio waves between the base station and
mobile phone by launching establish contact, so as to achieve the purpose of
voice calls. Electromagnetic interference with cell phone signals have an
impact, this situation will generally appear in the examination room.
Solution: Find
signal interference around the device, you can turn off or remove.
Especially when
the network is busy may appear a temporary fault, it will also have an impact
on the mobile phone signals. As often occurs in the bustling commercial
district phone call does not go out, others do not come to fight the case,
especially during peak periods, commuting and holidays often delayed.
Solution: avoid the downtown business
district, the peak time, signal
condition will automatically improve.
Is not caused by
external factors no cell phone signal, it is likely to be caused by the battery
voltage instability, inadequate power supply circuit receiving a signal, the
voltage fluctuating state, the received signal also will not be stabilized.
This phone can not access, even phone can not dial.
The solution:
high quality for a piece of the phone, the signal problem will be fixed.
