Dual Sim Smartphone Features
In addition to the traditional technical specifications to be evaluated in a smartphone with a large screen, such as the display, the camera, the internal memory, the RAM and the processor, for Dual SIM phones there are a few more technical features to take into consideration. Let's see which dual Sim Android phone to buy.
MicroSD slot and second SIM
Some dual SIM smartphones have one condiviso slot for the MicroSD and the second SIM, this means that you have to choose whether to enter another number, or, take advantage of the space to add external memory to the device.
It is not possible to use the available space to do both, except through unofficial methods, however, not recommended in order not to compromise the correct functioning of the device.
Slot 3G/LTE e GSM
In dual sim smartphones there is full support for 3G / LTE data network of a slot, while the other goes for 2G, therefore, it only allows you to make phone calls.
On more modern models there is the hot switch function which allows you to move the data connection 3G / LTE from one sim to another, without having to physically reverse them.
When buying a dual smartphone, make sure there is always support for the networks used by your operator.
4G / LTE support
Particular attention to some Chinese smartphones that don't support 4G / LTE and therefore do not fully ensure compatibility with Spanish networks. They are incompatible with the a frequency band 800MHz that some operators use for 4G, so you may have trouble connecting where the signal is weak.
Differenze tra Dual Standby e Full Active (o Dual Active)
The difference between the dual SIM Dual Standby and Dual Active technology it's very simple. The first keeps the two numbers active at the same time to receive messages and calls, but if one of the two receives a phone call, the other goes into standby and cannot connect to the network.

This way, even if you receive a call, the other number is not put on standby and can also be contacted. Among the other advantages there is the possibility to talk to two people at the same time, and to switch from one number to another without losing the line, very useful functions especially for those who want to use the device on a professional level.

Usually, in single sim models there is only one slot dedicated to the SIM card and one, apart, for the MicroSD; in Dual SIM it is possible to find two slots intended for SIMs and a separate one for external memory, or a slot intended for dual use, forcing the user to choose whether to expand the storage space or have two numbers always active.
