Dual-SIM phones are mobile phones that support two SIMs. Dual-SIM phones empower users with two phone lines on a single phone. You can take advantage of reduced call rates, without losing your existing line. You can also use one line for your personal life and the other for your professional life. If one network is erratic in a given location, a dual-SIM phone enables you to easily switch to another network with a better signal, giving you a more reliable connectivity. Here we will provide brief overviews of some dual-SIM phones.
Dual-SIM phones usually come with a dedicated button for switching between SIMs. The SIM that you are currently switched to is the active SIM while the other is the standby SIM. To use a particular SIM to make call or use other mobile services, you have to switch to that SIM. Some dual-SIM phones enable you to receive calls from both SIMs irrespective of which one is active. Such dual-SIM phones are said to be dual-standby. Dual-SIM, dual-standby phones are truly two phones in one. Without the dual-standby feature a dual-SIM phone cannot truly replace two phones. Some dual-SIM phones do not have the dual-standby, meaning that you can only receive calls on a particular line when it is active. If you are called on your standby-SIM, the caller will be told that your phone is switched off.
Another interesting feature available in some dual-SIM phones is the hot-swappable secondary SIM, which simply means that you can remove and replace SIMs from the secondary SIM slot without switching off the phone.
The hot swappable secondary SIM feature extends your phone beyond dual-SIM as you can easily swap secondary SIM with another SIM. Some dual-SIM phones will also store settings for each SIM and will remember them whenever you slot them in.
Here are some dual-SIM phones:
