What is a Dual SIM Card?
With the help of a Dual SIM Card you are able to use 2 SIM cards in 1 mobile Phone!
What are the advantages of a Dual SIM card?
Save yourselves the 2nd mobile Phone and distinguish between private and business calls!
Reduce your mobile costs quite comfortably, while you select the most inexpensive SIM card without changing the SIM Cards in your Phone!
What is the STK-menu?
About the STK (SIM tool kit) interface you are able to link applications on the SIM Card with your Phone!
You will find this in the mobile Phones at different places, for example, T-Mobile cards will have somewhere in your device "T-Mobile services".
From there you administrate the Dual SIM Card.
There you can switch between the cards and administrate other special functions of teh Dual SIM card.
The classical digital Dual SIM Cards use this STK-interface, and overlay the original STK entry,
an exception from this is the
GDS16th-A and the
GDS20th-A, which can use the 007 mode, so they leave the original applications of the Dual SIM card carrier.
This makes sense if you own, for example, a TwinBill card of T-Mobile, you would have than 3 phone numbers in only one mobile Phone!
What is the different between an analogous and digital Dual SIM card?
With the analogous Dual SIM card you switch between the cards by turning off and on your Phone!
The digital version uses an additional menu entry in your device from where you can select the second SIM card!
What is the different between the NoCut-Version to the Cut-Version?
The NoCut-Version does not need cutting the SIM Cards. The Cut-Version needs cutting the SIM Card, you can cut with a pair scissors or you use our special pincer!
Is it possible to use the fitted SIM-Card as normal?
The SIM cards can be adapted with the provided plastic adaptors again comfortably on the original SIM card size!
How is the dual adaptor SIM mounted??
The NoCut version is equipped with your SIM cards, afterwards the SIM card 1 is pushed in the slot of the device, the rest must be stowed away in the battery space in such a way that the battery lid still closes itself.
That's why we recommend basically the cut version with which the fitted cards are laid in the places SIM of the Dual SIM Card. The Dual SIM card has now the size of the SIM card!
How are the SIM cards reduced for the cut version?
Either you cut it with a pair of scissors, or you cut it with our special pincer!
Reduce the Dual SIM Cards supplied from G-Telware the battery?
All Dual SIM Cards, we offer, do not reduce the battery additional!
It is defined by the fact that usual digital Dual SIM Card on the market reduce the accu-running-time already without switching the SIM Cards!
Extreme case, up to 20% of the original battery run time!
Which of the Dual SIM Cards offered by G-Telware does support the UMTS function?
The analogous Dual SIM card supports, if it is compatible with the mobile Phone, always the UMTS functionality!
From the digital ones the GDSI3G is able to support UMTS/HSDPA/HSUPA.

My device recognises none or only one SIM card and/or boots in the off-line mode
After the punch or reaping of the SIM cards originate burrs the undesirable contacts produce, thereby it can come to error messages.
Deburr these please like in the
videoinstructions to see. On this occasion, the short slant is all-important in the SIM card!
Provide for the fact that the SIM cards lie in the card places very "swimming", so that no lateral mechanical tensions originate,
one good contact prevent.
Deburr if necessary a little bit more to reduce the mass!
If you have insert and upgrade very often the Dual SIM card, the contacts are getting more and more flat,
form out, hence, the contacts with a ballpoint pen of the back of the Dual SIM card (without the SIM cards) again!
With a graphite spike (e.g., usual pencil) you can plane the six rectangular contact surfaces from the mask layout!
If your card SIM is considerably older than 2-3 years, an exchange to a newer one should helps with the tip to your carrier/provider about the incompatibility to your new mobile Phone!
My device announces after a switch often a registration error
Exchange the SIM card and check whether the edges are deburred. On this occasion, the short slant of the SIM Card is all-important!
My UMTS mobile Phone boots in spite of all in offline mode
Switch your mobile Phone to GSM-only mode!
