Are sim cards re-programmable

Answer 1

well. well. well. there are 2 answers for this question. and a yes and a no.

for example in my case. i do travel to many cities and there i have to get a new sim card and insert it in my mobile. rather than carrying 2-3 bulky mobile phones? i can push all the data and sms and a-z info which can be stored in the sim card to another sim card. at present i got 8 sim cards and all are working and all from different cities. so i need to get an 8-in-1 sim card empty and reprogrammable so that i can push all the data from those 8 cards to one card and use it in one single card. this is the positive side of technology, where during dire need you can help yourself by saving time and money

going to a professional and get it done. you got sim card readers from companies like gemplus which offers a wide variety of sim card reader. and you can read the data and copy it to the blank sim card using the same reader which will then act as a writer. you (also may) recover deleted data as well, like accidentally deleted SMS and phone calls made of your phone via bluesnarfing and other techniques, you may recover the old untampered data before you got a sms virus from a very good well wishing friend of yours and recover the data and also use multiple cards. its programmable. yes.

but now the dark side. someone may sniff your mobile phone and smart cards used to punch in open locks off offices and blah blah devices and etc use imagination and gain access to your secure data. they may copy your mobile details, may get your bank account and pin and credit card and debit card pins and what not, anything which has to do with technology and profit is main motive and also industrial espionage. they may even clone your sim card and its not that tough. and you end up paying for those calls you never made, nor will ever. use imaginations to visualize how it may ruin/screw ;-) your life or someone else's.

blottom line: like 2 sides of a coin there are plus and minus points to each and everything. you need to decide which side are you in. and same with

technology too. you can use it to have fun and have profit at the cost of someone else and also may learn and develop.

check out "the hackers choice" wiki Google:the hackers choice and go to non-german and wiki up and look for cellular technology. you got a heck-a-load of info on this topic. and how you use is upto you. good luck.

p.s. before your adrenaline rushes to do something nastily evil think Z times, measure many times cut once. i.e. if you are a whistle blower? you may use it for your wishfull purpose else you may use it for the reason i am using it. backup 8 sim card's data and stuff all those in one. and save me space and hassle of carrying 3-4 mobile phone or 2-3 mobile phone with dual simcard, just use one universal sim card does the trick.

good luck.
