Usage of two SIM cards in a single phone is an option that phone users are searching more and more often in a mobile phone functions. Using a personal phone number and a work number in a single gadget can be very benificiary. Money economy by using two different tariff plans or two different providers or using cards with credits during the business travels – are only some of the reasons why dual-SIM phones are more and more popular. Users are not forced any more to carry two mobile phones since the producers invented ingenious methods to resolve this problem.One of the most recent models of dual-SIM phones is Evolio Duo 100. It works in two networks simultaneously (doesn’t need restarting for switching from one SIM to another), is equipped with 2 MP camera, video camera, Bluetooth, MP3 player and it is compatible with WAP, MMS,GPRS. The device can uses memory extensions up to 1 GB.
Dual-SIM Evolio phone has a battery of 1050mAh, webcam function and reasonable dimensions 109,8x49,5x15,3 mm and a weight of 95 g.
Sound quality is the essential quality for this phone. But the thing that is the most interesting for the users in such a model is the facility to work with both SIM cards. Here are some examples:
CALLS:
- in the moment when the owner receives call from card nr.1, appears also on the screen near the name of the caller the name of the card by what the call is received
- to make a call: a phone number is hit and then you have two options:
a) calling from the personal number in case if you hit the green button (see photo)
b) calling form the work number in case if you hit the white button (see photo)
CONCTACTS:
- contact number from the each SIM card are stoked in the Evolio Duo 100 in common, but the owner of the phone knows permanently to which SIM is corresponding the number, because there are symbols 1 or 2 near all of them. So, the user knows whether the number is on the card number 1 or card number 2.
SMS:
- when the messages are received the same rule as in case of contacts is used. Received/sent messages are marked with 1 or 2 for knowing which SIM received/sent the message.
-before sending the message the user has an option to choose "send from Master" or "send from Slave".
As a weakness we have noticed only the fact that the phone does not have a loud speaker. Otherwise it is a very good mobile phone. Extra Categories (currency converter, measuring system converter, calculator, e-Book reader, Health System-control, Organizer with calendar + task list + multi-alarm system) and an intelligent shortcut system so you can navigate in each submenu using only few buttons closes successfully the list of Evolio Duo 100 functions.
