Keys to keep in mind before buying a mobile with Dual SIM
1. How does Dual SIM technology work?
Unfortunately, most manufacturers do not offer too much information about how Dual SIM technology works and just announce that your product can work with a dual card.
In this sense, they do not usually specify the size of the cards that can be used with the model in question or if both cards are compatible with 4G connectivity. The only thing you have left is to do a quick research on the Internet to go on insurance.
All the smartphones This list works through the Dual Standby method. That means that both cards are on hold for the entire time and that you can only use one of them at the same time.
It will not be necessary, however, that you change the SIM manually or restart the phone every time you want to use the other. Of course, if you are calling with one of them, you will not receive calls made to you on the other number.
2. What is the difference between Dual Standby and Dual Active?
We have announced that the phones on this list come with Dual Standby because they can only be used one at a time. There is also the Dual Active method, which allows you to have two telephone lines running and receiving calls simultaneously.
If you have an Android phone, your operating system has a menu where you can specify which SIM card you want to use for calls, video calls, messages and mobile data. You can choose a SIM for each function or choose to be asked before.
3. 3G or 4G connectivity?

In addition, you must specify in your settings smartphone which of them you want to use with this 4G connectivity. Of course, if you are using it on one of the cards and you receive a call on the other, this connectivity will be disconnected.
Instead, you can use both cards at the same time with a 3G mobile phone, somewhat slower when you want to watch videos on streaming or perform other tasks on the Internet than fourth generation connectivity.
4. Where are contacts saved?
You may worry where the contacts of both SIM cards will be saved, since nobody likes the idea of losing them by mistake. By default, these will be saved in your contacts list smartphone.
You also have the possibility to hide the contacts of one of the cards. In the Contacts app on your mobile, tap on the three vertical dots, followed by Contacts to display. Now you can select the contacts of one of the two SIMs.
5. What price are you willing to pay?
One of the factors to take into account is obviously the budget you have allocated to a smartphone with Dual SIM. Vers that in this classification there are phones for all budgets: from 100 to 700.
6. What other benefits do you need?
On the other hand, you should not guide yourself just in case a smartphone It has Dual SIM technology or not. You should look at the other benefits offered as if it were any other mobile and analyze whether or not they adapt to your needs.
