Not only iPhone, Blackberry . are portable from abroad to unlock, the phones of Vietnamese carriers are also unlocked as usual. This is essentially the same as a subscriber leaving the network, causing network headaches.

Operators such as MobiFone, VinaPhone, Viettel, Vietnamobile, or before that S-Fone all cooperate with phone manufacturers to launch SIM packages with phones.

Simple, cheap

When asking to unlock an internal phone in some shops in Thanh Xuan district (Hanoi), most of the store owners demand to leave the phone. Meanwhile, shops in Tay Son Street and Vong Street (Hanoi) said: the price of unlocking is 100,000 dong and takes after an hour.

According to people in the profession, the unlocking is quite simple with the equipment available. Only need to invest about 10 million, there is a whole set of device unlock devices. With these devices, the unlocked device only needs to run the software within 15 minutes to return to the " original " state, which can use any network (except CDMA network) in Vietnam.

However, only a few big stores or shops specializing in repairing and unlocking cell phones are ' shopping '. Most small shops often follow the old way of receiving customers' machines, transferring them to these centers and eating the difference.

Mr. B., the owner of a shop specializing in unlocking machines in Ho Chi Minh City, said: 'One week, we can receive about 20 - 30 machines belonging to network sets. Most are brought by small shops, a few are by retail customers. Previously, the number of unlocking machines was quite large, mainly the lines of VinaPhone, MobiFone, Viettel such as Nokia 1200, Samsung E1110, Huawei T156, T202, . Depending on the quantity, the fee can range from 10,000 VND - 50,000. d '.

In addition, this network when ordering production with Samsung, also required to strengthen new security techniques, want to unlock must have a new account of the company to intervene .

However, how effective it is, because hackers will also have enough " skills and solutions " to deal with. On some forums, there are some kind of jokes like: " What's the problem. Vietnam still unlocked iPhone or some Vodafone or T-mobile phones, . then unlocking the power What is so special about 'domestic' voice? '

Perhaps noticing the general psychology of consumers and also wanting to ' restrain ' users' network speeds, besides the ' tough ' measures, networks are also implementing some ' flexible ' methods. 'more, for example: donate a' money 'immediately to the account when buying a machine that breaks down the promotional amount evenly for 6 - 12 months. And the majority of user comments said: " The best way is for operators to regularly take care of their customers rather than using rigid technical measures ".
