Method of unlocking a mobile telephone type wireless communication terminal |
摘要 |
In a method of unlocking mobile telephones, in particular one using the "SIM-LOCK" method, the user of the telephone submits an unlocking request directly to the manufacturer of the telephone and the manufacturer sends unlocking information to the telephone after verifying with the operator that the user is entitled to unlocking. This simplifies the administration of unlocking requests and makes it more reliable.
