Dell are the extremely popular computer manufacturing company that have been the number 1 PC manufacturer in the world for some time. To complement their strength in computer manufacturing and gain ground in the growing mobile phone industry, Dell released a number of phones, with varying degrees of success. The Dell Streak and Venue Pro being amongst the most popular.
Some of the Dell handsets use the Android operating system with other using Windows Mobile. Both of these modern systems are programmed with an easy to follow unlocking pattern, which simply requires you to enter the unlock code once prompted by the phone. This prompt will usually appear on the phone when a non-accepted SIM card is inserted.
For Dell handsets, only one unlock code will be needed, as this will remove any active locks on the phone, which are preventing you from switching SIM cards.
