There are two options available in the market to buy a phone where one is unlocked phones and the other locked phones. You can buy the manufacturer unlocked phones directly to use any of the network carrier services on your mobile. However, these are a bit expensive when compared to the locked phones. The locked phones are offered by the network carriers, which lock them to their network SIM so that customers can use only their network services till a certain time period. These locked phones are offered at cheap rates as the network carrier companies retrieve their money through their locked network services from the client. By buying the locked phones you can get any latest model phones in affordable rates, but you are locked to the network carrier.
 

However, with many third party sites offering their services to unlock the phones using factory codes you can simply unlock the phone bought from the network carrier. You can have the Sim Unlock iPhone services by just paying around $6 based on the phone model and you can get the factor code within 2 to 5 days’ time to Sim Unlock iPhone. The third party sites can unlock your iPhone on all iOS versions either using the IMEI code or the iTunes. Similarly, if you want to unlock Alcatel phones which comes with unique subsidy or network code you need to look out for the IMEI code that can be found underneath the battery of your mobile or press *#06# on the keypad for the IMEI code to display. By sending this code to the third party unlock Alcatel phone you can receive the code to unlock your SIM within 4 hours’ time.
