The Galaxy S3 is an excellent smartphone Android but it also has some negative points in my opinion, such as the need to use a chip (SIM) that is smaller than the previous standard of chips. This fashion began with the iPhone, of course! I agree that the standards need to go on changing as time passes, as happened with the SD cards, for example. They were physically getting smaller, and each time with a larger storage capacity. Today it is hard to even imagine the use of a SD card on your physical size the original in the compact smartphones that we have. But and the chip carrier? Want the same change?
The difference between changing the SIM card and the SD card is the following: how much you telephone exchange, usually buy a SD card again, since they are not always what you wore before would you meet in terms of capacity. But you keep your number and do NOT would need to swap the SIM card to replace the device! Including, the possibility of keeping the number when switching from the device was one of the motivations of the creation of the GSM technology and the use of chips as it is today.
Considering that those who spend good money on a next-generation smartphone like the Galaxy S3 or the iPhone, spend more 10 dollars to turn your SIM into a minichip will not be a problem, right? After buying the Galaxy S3, I went directly to a shop of Oi and transfer my number from the chip common to the minichip. The procedure was done in the hour and in 10 minutes was already with the minichip working within the Galaxy S3, as in the photo below.
In any case there are ways to turn your SIM in a minichip. Just cut the chip in the correct format because the connections electrical are “apparently” compatible. See the figure below that are not exactly the same. I thought in this possibility but soon changed my mind. The Galaxy S3 has 1 year warranty and a modification such as this in the chip could easily be reason to void the warranty, especially if the problem is related to the fitting or operation of the chip. Not to mention the headache if something goes wrong, both to get another chip how to repair the device that can be damaged.
If you bought a Galaxy S3 or iPhone of last generation, spend the most 0.1% of the value to the unit and buy a minichip for your company in the official way and with the warranty due. It is logical thinking! Avoid this ugly workaround to cut out the chip from becoming a example of the cheap that is expensive!
