How to Solve SIM Card unreadable in BB Z3, Z10

How to Overcoming SIM Card unreadable

I’ve used several brands of smartphones especially big brands, and of course Blackberry. Every
brand must have happened damage to its product with varying damage and
one of the damage that I will discuss here is damage related to SIM
card.
There may be some SIM card related damage that ever happened but I
took 3 damage I have ever experienced and it seems like this damage is
common damage.


The above damage is the damage I have encountered and there may be other damages related to the SIM Card. Some cases that I encountered occurred in BlackBerry 10 but never happened in some other brands. From the above mentioned damage we see what happened and what caused the damage.SIM Card unreadableUsually
this damage is marked with insert insert SIM Card or insert SIM card
which shown in operator indicator display even though we have inserted
SIM card to smartphone device, for BlackBerry device usually exist in
top right.
 

This
damage can be caused by a SIM card or mobile device, and to make sure
it is by trying the SIM card to another smartphone that has been
confirmed is not problematic.
If after a try on several smartphones experienced the same thing that
is a SIM card insert then it is ascertained damage comes from the SIM
card.


Cause Insert SIM CardDamage to the SIM Card chip, this is a common malfunction where yellow chips that are connected to the phone are damaged. Inside
the chip is stored data and also the interaction of DC voltage to the
SIM Card, and more detail damage can be caused by some things but
essentially the chip is damaged and can not be used.
I never experienced that SIM is not readable only once in a while but
it becomes frequent and finally can not at all, so if often experience
this damage better soon the resolve because it could be when we need a
sudden SIM can not be used.




The solution of the SIM card chip damage is nothing we can do apart
from asking for a change to the operator, if we try to tinker and
finally can, based on that experience does not last long and will happen
again.


Not perfectly connectedBetween SIM card and phone chip connected using SIM reader connector in mobile device. Not connected perfectly can be because the connector is lifted so that it does not stick perfectly or SIM Card is dirty.


The
solution of damage because it is not connected properly, the first step
is to clean the SIM card by rubbing using pencil eraser and do not rub
with metal objects let alone sharp objects.
Also check that the connector pins of the SIM connector are aligned,
if one is lifted and you dare to do it to lift a bit with small tweezers
or metal, but if you do not understand and do not want to take risks
then you can take it to the service.


SIM size is not perfectIn
general, masi widely used in mobile phones, smartphones and tablets
using SIM card-sized mini SIM, but for BlackBerry 10 are all using Micro
SIM except BlackBerry Passport already using nano SIM.
Operators
usually already provide all types of SIM card sizes so that we can
change the size according to the operator, and the operator has stock
SIM cards of various sizes made from the factory for all sizes with high
precision.
But
sometimes some users when switching devices with different SIM does not
request the exchange of SIM to the operator and do the self-cutting
that sometimes when cutting, the size is not appropriate or uneven,
especially if the cutter used is dull because it is often used.
Those who do such deductions are usually mobile phone shops to accommodate the needs of customers who buy their phones.


Solution
if the size of the SIM card is not fitting is to switch to the operator
and also avoid using the SIM card adapter if moving to a larger SIM
card, for example from the micro SIM to use the mini SIM users will
usually use the rest of the previous pieces to connect to a mini SIM.
One effect is that it can cause damage to the device, especially the mechanical components of the SIM card. So far some mobile phone manufacturers do not recommend the use of the
adapter, one of which the Blackberry does not recommend it.


Mobile phone hardware malfunctionWhen the SIM card is paired to other devices it can be read then most likely damage from his mobile device. As
previously described the possibility of SIM card connector device that
is not attached perfectly and you can straighten it yourself or ask for
help place the service.
But if the connection is already
