The most advanced and technologically sound operating system which is being used in most of the Smartphone and tablet computers today is Android. This OS has been introduced, developed and owned by the OHA (Open Handset Alliance) and the leader of this alliance is none other than Google, the giant in the world of technology.

Almost all the Smartphone are now being operated by Android and the number is increasing quite fast. Most of these Smartphone are SIM free which means these Smartphone are free from all sorts of network obligation. So anyone can use these Smartphone with any desired network and they are completely free to do that. To assist the concept of SIM free the concept of SIM only deals has been developed. If you don’t know what a SIM only deal is then consider reading the next paragraph to have some idea about it.

SIM Only Deals:

SIM only deals or contracts are signed between the two parties involved in the process (the cell phone user and the network provider). The main idea of the SIM only deal is the user will pay only for the using the SIM card and nothing else. There is no handset included in the deal, so the user can use any handset with the deal. The deals are actually combinations of minutes, texts and data. Different deal offers different combination and cost differently. But to have a SIM only deal one have to have a SIM free handset to use with. Even if anyone is having a deal running he or she may get a SIM only deal. Suppose that person’s deal is going to be ended soon and he wants to keep going with the current provider but don’t want to upgrade his handset. In this situation he can get a SIM only deal which will allow him to use the current SIM card but will not be needed to upgrade the handset.
