Eroare : cartela sim a fost indepartata ,reporniti dispozitivul . Timp de 3 saptamani am tot incercat rezolvarea acestei probleme prin diferite metode ,respectiv : - unroot si actualizare la ultima versiune oficiala - schimbat 3 cartele sim - injurat toti angajatii Telekom care raspundeau la 1234 - instalat si reinstalat modemul - instalat ROM prin odin , versiuni UK , FR , RO ...etc - incercat alte cartele sim vodafone ,orange ,telekom - ingrosat cartele sim Esec total , nimic din ce e scris mai sus nu a functionat . Singura metoda care a functionat este desfacerea carcasei si adaugarea unei bucati de carton peste mufa card reader astfel incat capacul sa preseze si sa se faca contact perfect . Atentie ,nu schimbati degeaba card reader-ul ,si cel nou o sa faca la fel. Atentie cand desfaceti telefonul ,marginea aia ieftina se rupe foarte usor . Tutorialul complet cu poze il gasiti aici : How to fix Galaxy S4 "Sim card removed&… | AT&T, Canadian Bell, Rogers, Telus, Virgin Samsung Galaxy S 4 | XDA Forums In plus fata de tutorial ,eu am scos mufa card reader si am pus-o la loc inainte de reasamblare (nu stiu daca a contat),am folosit carton in loc de pluta .

Un prieten de al meu are o cartela sim care este blocata,nu poate fi sunat (Cand suni zice ca cartela a fost deconectata ) nu are credit,nu are minute,nu poate primi mesaje.Dar el poate suna in orice retea oricat doreste ,poate folosi internet nelimitat,poate trimite mesaje nelimitate. Intrebarea mea e daca a mai intalnit cineva cartele de genu si daca stie cum se poate face rost de ele? EDIT:Imi cer scuze,daca poate un moderator sa mute topicul in https://rstforums.com/forum/discutii-non-it.rst multumesc.(M-am grabit si am postat direct in off-topic)

SIM cards are among the most widely-deployed computing platforms with over 7 billion cards in active use. Cracking SIM cards has long been the Holy Grail of hackers because the tiny devices are located in phones and allow operators to identify and authenticate subscribers as they use networks. A German cryptographer Karsten Nohl, the founder of Security Research Labs claims to have found encryption and software flaws that could affect millions of SIM cards, and allows hackers to remotely gain control of and also clone certain mobile SIM cards. This is the first hack of its kind in a decade. Nohl will be presenting his findings at the Black Hat security conference this year. He and his team tested close to 1,000 SIM cards for vulnerabilities, exploited by simply sending a hidden SMS. According to him, Hackers could use compromised SIMs to commit financial crimes or engage in espionage. Once a hacker copies a SIM, it can be used to make calls and send text messages impersonating the owner of the phone. The exploit only works on SIMs that use an old encryption technology known as DES. DES is used in around three billion mobile SIMs worldwide, of which Nohl estimates 750 million are vulnerable to the attack. GSMA, which represents nearly 800 mobile operators, will notify telecommunications regulators and other government agencies in nearly 200 countries about the potential threat and also reach out to hundreds of mobile companies, academics and other industry experts. Nohl believes that cyber criminals have already found the bug. Now the theoretical details of the vulnerability is out, he expects it would take them at least six months to crack it, by which time the wireless industry will have implemented available fixes.
