Q1. How does the Dual SIM Card Holder works?
The Dual SIM Card Holder is the size of a normal SIM card, it will be installed like the normal
way you install your SIM card into the phone. The SIM card holder would house 2 SIM cards.
You just need to power off and then power on the phone to toggle between the 2 SIMs.
Q2. Could both SIM (lines) be active at the same time?
No, only one SIM card could be active at anytime, there isn't any product in the market yet
that allows both card to be active at the same time. If you wish to continue receiving calls from
the other non-active SIM, you could divert the calls to the active SIM card before toggling
between the SIM. Please note that SMS/MMS could not be diverted.
Q3. How to switch between the 2 SIM cards?
You just need to power off and then power on the phone to toggle between the 2 SIMs. For
some Nokia phone models, you just need to key #3370# from the standby menu, the phone
will power off and on by itself. Nokia phone that uses Symbian OS; like the 3650 and 7650;
does not support the #3370#.
Q4. How to install two normal SIM cards into one Dual SIM card Holder?
The installation steps are as follows,
1. Original SIMs need to be cut to the appropriate size.
2. The cutting could be done by using a pair of scissors or by our cutter tool.
3. Our cutter tool is more recommended as it is more precise than a pair of scissors.
4. The cut SIMs are then place onto the Dual SIM card Holder.
5. A sticker or metal bracket is placed over the holder, depending on the phone to be
6. The sticker or metal bracket is for the purpose of securing the cut SIM to the Dual
SIM card holder, but it may affect the thickness of the Dual SIM card Holder.
7. This completes the installation.
8. Don't worry; we will perform all the above steps for you as part of our free installation
Q5. Will cutting the SIM card permanently damage the SIM?
No, it will not damage the SIM if cut with out cutter tool.
Q6. Why could the SIM still function after being cut?
The metal contact of the SIM card is the most important portion of the whole card. We are
cutting out the metal contacts and discarding the rest of the card, which means we still retain
the important portion of the SIM card. Information on the SIM will not be lost after being cut.
Q7. Could all SIM card be cut?
No, only SIM card with the metal contact close to the edge of the card could be cut. Please
refer to our SIM Compatibility table for the supported type of SIM card. We will not cut
unsupported SIM card. We will only cut unsupported SIM if you insist and we will not be
responsible if it could not work.
Q8. Is the cutting process "Non Reversable"? If I decided not to have 2 SIM Cards anymore,
does it means I can't use the SIM anymore?
No, we have a recovery kit to convert the cut SIM back to a normal sized SIM, in cases when
you decided not to use 2 SIM cards or when you accidentally spoilt the Dual SIM card Holder
and do not wish to get a replacement. The recovery kit is FREE together with your purchase.

No, modification of the phone is not required, only your SIM cards were modified.
