Those who keep one mobile number of the office and one for home now do not have to carry two different cells, and can handle their work with a two SIM mobile phone. Two SIM phones are of two kinds – standby double SIM phone and active twin SIM phone. In standby twin SIM telephones, dual-SIM adapters were made available to use in regular mobile phones to permit them to contain two SIMS and to change from one to another based on the requirement. The busy two-SIM phones can work with two SIMS, both of which could be active at the same time. The dual sim technology has taken its course through the years and it’s not just a matter of a single night. Formerly there were sim holders that was a good start. These dual sim holders would fit behind the battery of the mobile phone and would hold two sims at one time. Though these were not active at the same time, but you could use the other sim by restarting your mobile phone. The dual sim holder was though a good beginning but it was not the right solution that completely fulfilled the demands and it was improper and more inconvenient.
Then the next step was dual sim adapter which was not a lot different from the sim holder but it provided the necessary evolution. The sim adapter works the same way as the dual sim holder functions but the difference is that the adapter is be set in the sim’s place holding two sims inside the sim jacket. This technology again had the negative and awkward side to it as it was not automatic and the sims weren’t active at the exact same time. Exactly like the sim holder, you have to turn the phone off and back on to activate the other sim. With these advancements, some of the developers thought of a more solution. That was to place two mobile phones in one casing or holding. This idea got developed and resulted in the dual sim smartphone which would share the very same LCD but keep the two sims active at exactly the exact same time. Today dual sim smartphones are very popular with the youth specially. These phones provide you the choice to maintain two numbers active at the same time and you can also make and receive calls from two different networks at the same time. The sad news is that there are only a few producers who have taken this to big stage and the more reputable companies have not yet established their campaigns.
