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 include two SIMS and to change from one to the other according to the requirement. The busy two-SIM phones can work with two SIMS, each of which could be active at the same time. The double sim technology has taken its course through the years and it’s not simply a matter of a single night. Formerly there were sim holders which was a decent start. These dual sim holders would fit behind the battery of the mobile phone and would hold two sims at a time. Though these were not active at the exact same time, but you could use another sim by restarting your mobile phone. The dual sim holder was though an excellent beginning but it was not the ideal solution that fully 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 within 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 another sim. With these advancements, a few 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 led in the dual sim smartphone that would share the same LCD but keep the 2 sims active at the same time. Today dual sim smartphones are very popular with the youth especially. These phones give you the option to maintain two numbers active at exactly the same time and you may 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 large stage and the more reputable companies have not yet established their campaigns.
