To do this we will simply have to enable WiFi calls, which will mean not only being able to receive these without SIM coverage, but also greatly improving the quality of any made in any way, so if you have not tried it yet, keep reading.
Call without coverage with your iPhone
To do this, as we said, we would have to enable WiFi callingwhich would give us the possibility of doing these, or even receiving them, thanks to the internet, even if we do not have coverage from our company, which would be great for us in a rural house, a train, or even the plane itself, where the airlines already They offer WiFi connection, but where we will not have our SIM network.
- Go to Settings > Mobile data.
- If your iPhone has two SIM cards, choose a line (in the SIM Cards section).
- Tap Wi-Fi Calling and turn on On This iPhone.
- Enter or confirm your address for emergency services.
This method can have many uses, from those already mentioned, where we do not have coverage, to the moments where we do have coverage, but we do not want to use the mobile plan, since many people have limited minutes and do not want to spend them. This way you will use WiFi, so your data plan will remain intact.
Furthermore, it will be a way of battery savingsince being at home, we can put on airplane mode, using less battery than normal, and we will continue to have internet and be able to receive calls, since these will go through WiFi.
By default, the iPhone will use the best method, that is, if, for example, you are making a call over the Internet, and suddenly, we are left without Wifi, due to a power outage, moving too far away, etc., it will connect. automatically to the mobile network to continue the call without ending it, just as in the opposite case, in which we can be going up to our house while talking on the phone, and when we enter it and connect to the WiFi, improve its quality.
This there is no cost and it will depend on your mobile model, data company and WiFi provider, however, it works great in most cases and the best thing is that it is free and very easy to activate, it has no drawbacks.
And you, did you know this “trick”? The truth is that it costs nothing to activate it, and it will always have more benefits than disadvantages, so if you don't have it configured yet, I don't know what you are waiting for. Go and try the difference in quality between activated and deactivated, you will see how noticeable it is, a lot. Especially in bars, restaurants and places where there is little signal inside, but that have a free WiFi network to connect, the difference is brutal.
