The dual SIM smartphone: useful or gadget?

 If dual-SIM smartphones are happy days in China, Europe has for several years passed the multiplier to expand its offer, in view of a demand ever stronger. So, the dual SIM mobile phone, actual evolution or simple gadget?

DOUBLE LIFE

Separate your professional life from your personal life: this is undoubtedly one of the major advantages of a dual SIM smartphone. No more need to bustle permanently with its 2 mobile phones. Equipped with its two SIM cards, it allows you to go from one life to another at the touch of a button. Some models can offer you to separate your directories, history not to get tangled brushes ... finally, the lines.

 More generally, the dual SIM smartphone can be a practical solution to preserve your privacy, by offering you the possibility of having a secondary line permanently (or "temporarily", by means of a prepaid card). What you avoid to distribute everything to the first comer your main phone number.

FROM ONE NETWORK TO ANOTHER

Nothing is easier with a dual SIM model. It's up to you to have fun combining the performances of two different networks. The goal is, you guessed it, to find the ideal complementarity between two operators in order to maximize the ability of your mobile to "hang" the best signal possible. Here again, the prepaid card may initially be an option to test this or that operator and help you make the optimum choice.

DIVIDE AND RULE

On the one hand, SMS / MMS and telephone communications, on the other, Internet surfing. On one side a SIM card with a "standard" subscription to make your calls and "text" galore, and the other a 4G SIM card with a data only subscription of 3, 4 or 5 GB to surf at will. Using a dual-SIM smartphone, you will have the possibility to organize your phone by "use".

WITHOUT LIMITS

Finally, having two different operators on one and the same phone obviously makes sense when one is always (or often) up and down the world. Or, simply, when you live near a border. A dual SIM terminal will avoid you the surprises of overcharging (if you do not have the option of roaming or "roaming"): you just need to give your mobile a SIM card of the country in which you reside, that whether for a holiday resort or for recurring round trips for professional reasons, for example. What stays reachable internationally as "local" on a single phone.
