Samsung S4 users might want to unlock their phones in order to change carriers. This happens when they are either dissatisfied with the present one or might want to visit another country and use the local network.
The first step is to contact you current carrier to see if they will do it for you. If they don’t agree, go to a third party with the IMEI number of the device. This might make the phone warranty void. A lot of online and offline sources are there to provide an unlock code. While putting in a new carrier SIM, you will be required to punch in the same. If you don’t have the SIM handy, but want to be prepared beforehand, put the code on the dialer in this format: #7465625*638* (unlock code)# or #0111*(unlock code)#.
Don’t put in wrong codes more than 10 times as that will get you stuck with the present carrier forever. Unlocking doesn’t guarantee that you can connect to a new service as that depends completely on which networks the phone is built to connect to. Use your model no. to determine which 2G, 3G and 4G LTE wireless band the phone can access and also if they use UMTS/HSPA/ EV-DO.
