Hi all, can I know whats the difference between 16k/32k/64k/128k sim card? Let say I'm using 16k sim card, am I able to enjoy full 3G speed while surfing?

Thanks.

the capacity is different..
thats all i think..
not sure..
wait pro come in give comment..

Should be the capacity only but some people say 3G need to be 128k to enjoy full speed not sure about this

so nobody know nothing ?

I googled about this and did'nt get any answer
just found this thread

128k can store more function such as 3g and number

smartcard (in general) or SIM card (for mobile) is like a ultra-micro-mini computer.

it has a processor and storage. This storage is very small because it serves a very basic function (like floppy -> cd -> hdd).

similar to hdd, u have different type of "partitions" for different kind of "applications"

the larger the size, the more "applications" can be fit into.

why 3G sim (it's called USIM or Universal SIM) starts from 128K because it needed a dedicated "application" for 3G functionality.


off-topic: do you know our MyKad has different functions? National ID, e-passport, drivers license, MEPS, ATM, Touch'n'Go?

all these are individual "applications" stored inside a smartcard chip.

Each application DOES NOT interfere with the others. It has it's own multi-level encryption and authorizations.

Each entity (or govt / private agencies) dictates their own security and HIGHLY proprietary. Each security level has 2 type of encrytion/decryption key: PRIVATE and PUBLIC.

for e.g. to access drivers license, u need the PUBLIC decryption key and access authorization from National Transport Dept.

To update your IC, u go to National Registration Dept. To reload TnG, u go to Touch'nGo counters

why we can "read" these info everywhere because data is retrieved ONLY (with PUBLIC DECRYPTION key). You CAN NOT write/overwrite any information into the chip without knowing the PRIVATE DECRYPTION/ENCRYPTION key.

ohh thanks that was helpful

it's mean for 3G user better take 128k sim right ?

will get mine soon

capacity n speed broo..

Capacity only. NOT speed. The reason why they need the extra storage is to store all the configuration and added features on the SIM. Nowadays we don't store our contacts on the sim itself so pretty much you can neglect the storage size as long as the sim itself can offer the added 3g functionality. The speed depends highly on the package which you signed in and the coverage area. Surfing on a congested zone might yield a lower speed. Just my 2 cent

no such thing my old maxis simcard is 64k not upgraded to 3G. I just need press code to activate 3G using till now also no problem.


The 16k,32k,64k and so on its the memory capacity how much it can store such as smses and phonebook including some additional features

128k can store more contact num i think

Yes. But what's the use of storing 1 name with 1 number when today's contact storage is somewhat limitless.

Gemalto is a very huge corporation, merged between Gemplus and Axalto few years back. A LOT of smartcard/sim card/credit card uses Gemalto's chip.


Also, there will be 1MB USIM (or MegaSIM). Google it.

Any of the teleco provide 256K simcard? So far I know is maxis provide only.

Actually does it matter? How often do you use the simcard memory?
These days ppl use phone memory


Even it support the sim memmory they divide it to like 5 phonebook.

Why do you need such big simcard?

the sad thing is that the divided phonebook is not linked to each other... if i switch phonebook2 d and my fren in phonebook1 called, no name will come out... duH~

lulz so it does'nt affect 3G speed at all

no need change,keep my 16k sim

not effected i am also using 16k sim card for my 3G also no problem

then copy the contacts in the sim to your phone.

Is there any reason why maxis 128k sim have a 3g ready thing on the simcard?

hmmm. my celcom blue have big sim, xpax 3g have small sim cip. so size dosent matter. both 3g sim.

didnt know there's such a thing... good to know...

i usually store my contacts in my Sim card... means consume space...
does it affect my sim card 3G capability?

The sim card memory, like explained in previous post, is used to store contact details and sms, if you choose to use sim card memory on old phones. e.g. nokia 3310, 8250, etc.

Nowadays, most phone uses its own memory to store contact and sms. Or you can opt for memory card (micro-SD, etc.), hence it can store many multiple times more than the 64/128kb sim card.

The advantage of using SIM card to store, is you can put into other phones and straight call numbers in phonebook previously.

The SIM card memory storage has nothing to do with mobile download/broadband speed. 1kb is more than enough to store all the configuration strings.

1KB settings is one thing.

the applet is another matter because it take space.

Actually big sim and small sim got difference?

No difference for all current latest h/p. Unless you are still using Nokia 8250, 3310, etc. and you choose to store contacts and SMS in SIM card.

128K is better laa...

can install lots of java application provide by d network provider n oso banks...

Well whenever you change a phone you will find a larger capacity simcard handy

all telco have 128k sim? coz my maxis oni 64k..didnt have easyacces option

Yes I think but you need to pay to get 128k sim

I am using 32k simcard also have easyaccess. Maybe u look at the wrong place of your phone?

highlight this to Maxis service centre.

they should provide free fix or free sim for you.

When your phone cannot on, and need to repair, thats you should think twice you should save your contact in your phone memory or simcard memory.

To save my contact, I prefer save it in my simcard.

ya..
me too..
prefer save in simcard..
if change phone no need to hassle to move the contacts from old to new phone..

I just sync with the pc. The puny little storage isn't big enough to save a single name with address, pics, multiple contacts and description.

My 16k sim dont have easy access...

Older phones cannot sync with PC

From what I recall, phones that can transfer contacts via bluetooth can literally backup the data correct me if I'm wrong.

for sure dont hav ler...16k only oooo

the larger the space the more developer can store mini apps inside the USIM, but then use 3g or not, does not matter one, once 3g activated use what K sim card also can one geh

I don't really agree with it. With Nokia,
(i) I can backup Phone Memory into Memory Card and manual backup out into my PC
(ii) Use PC Suite to backup Contacts, SMS
(iii) Use Online Ovi to backup Contacts

I have all in place. If it is urgent, I can buy the cheapest S60v3 phone and restore within <1 hour.

In fact, I have done option (i) before to swap a phone. All apps and data are intact.

Agree on this point.

hi guys...a noob question here...how to check the capacity of the SIM? thanks

Just use logic Simcard is for emergency just like phone failure but for normal usage on select phone memory. Just remember anything transfer from a device to another device is always slower compare to device that transfer directly

wut capacity u want to check??

is it d size???just take a look at d back of ur sim...
c what is written there....

either 64K or 128K

thx...check d..mine is 64k

normally, all standard sim comes wif d package is 64K....but not all..like xox comes wif 128K..n some others i think...

for more contacts n sum other app only mehh

from what i know is, umobile 128k sim card can store 1000 number. no saperated phonebook. and some of the 64k sim card restrict maximum characted u can save as the name. example if you put lelaki anak lelaki, the sim will not store all the car. instead they will only store lelaki ana something only.

yup restrict max character is not good thing

do we have to pay for using ovi service?
do we charged if browse ovi via phone?
