In short, SIM card-free calling refers to calls made over mobile data, Wi-Fi, or a hotspot via VoIP technology or other supporting calling apps.
SIM-free calling is commonly useful when traveling to other countries or for those seeking cost-effective communication.
How to call without a SIM card? Here are the methods
You can easily make calls over the internet without a SIM card, using devices like smartphones, laptops, or tablets. Here are the ways to make the call without the SIM card:
1. Using an eSIM
An eSIM, also known as an embedded SIM, is pre-installed in smartphones and tablets. That is, instead of a physical SIM card, it exists in digital form that you can activate by downloading the carrier profile or scanning the QR code.
An eSIM, like a physical SIM card, connects your device to the mobile network for calls and mobile data. Without removing or inserting your SIM card, you can switch between the carriers.
2. Wi-Fi calling
It is another method you can choose to call without a SIM. Allows users to make or receive calls over Wi-Fi instead of using the traditional cellular service. It uses an internet connection to establish communication. On many modern devices, enabling Wi-Fi calling lets you automatically switch to it when Wi-Fi is available.
3. Using VoIP technology
Voice over Internet Protocol, or VoIP, enables making and receiving calls over an internet connection. This communication can be via Wi-Fi, mobile data, or a hotspot. Thus, it lets you get a SIM-free call.
It is useful for personal and business purposes, mainly for companies making international calls. You can make VoIP calls using a VoIP app like Moon Dialer, which offers unlimited high-quality international calls at an affordable cost.
4. Use an internet-based calling service
Internet-based calling apps such as Microsoft Teams and Facebook Messenger are another great alternative to SIM-free calls. By downloading these applications, you can enjoy seamless communication.
However, one limitation of these apps is that both the sender and the recipient must use the same platform. For instance, if a person is making a call over Microsoft Teams, then the receiver can only communicate while using it.
