WHY UNLOCK GSM PHONE?
- Using a national network cheaper;
- Switching between the subscription and pay in advance.
Note: sometimes it also works without unlocking.
RISK OF RELEASE :
There are risks in unlocking your phone:
- "Tampered" (Ericsson)
If your phone must be returned to the store for any repairs, they can see you did "unlock". Some phones are protected from Ericsson to unlock: After you try to unlock it display "Tampered" and no longer work: you must bring it back to the store. In addition, the type of unlocker could be a prutser and damage your phone by accident. There is no insurance for this, do not let the unlocker fool you!
