The Advantages of Wi-Fi Calling: A Comprehensive Guide

Wi-Fi Calling is not just another app-based service like WhatsApp or FaceTime. It is a technical standard that has been jointly agreed upon by smartphone manufacturers and mobile network operators. One of the key benefits of Wi-Fi Calling is its compatibility across all operating systems and networks, making it a convenient feature for users regardless of their device or network provider.

Exploring the Main Benefits of Wi-Fi Calling

One of the most significant advantages of Wi-Fi Calling is the ability to make calls even in areas with poor mobile signal coverage, as long as you are connected to a Wi-Fi network. This feature comes in handy in locations like basements, modern office buildings with insulated windows, or remote areas with limited mobile reception. Additionally, with a stable Wi-Fi connection, the call quality is often superior to that of a weak mobile signal.

When traveling abroad, Wi-Fi Calling can be particularly useful. By connecting to a hotel Wi-Fi network overseas, you can make calls back home without incurring international call charges. This is especially beneficial for users with flat-rate plans, as it allows them to stay connected without worrying about expensive roaming fees. Moreover, incoming calls to your mobile device can seamlessly transition from Wi-Fi to LTE or 5G networks as you move out of Wi-Fi range, ensuring uninterrupted communication.

Beware of Hidden Costs: Understanding Wi-Fi Calling Charges Abroad

It is essential to note that unstable or slow Wi-Fi connections can impact call quality negatively. When using Wi-Fi Calling to dial local numbers while abroad, such calls may be billed as international calls from your home country, even within the EU where roaming charges do not apply to Wi-Fi Calling. To avoid unexpected charges, it is advisable to disable Wi-Fi Calling and switch to the standard mobile network for local calls while traveling internationally.

Pro Tip: If you need to make local calls while abroad, consider switching off Wi-Fi Calling and using the standard mobile network for cost-effective communication.

How to Activate Wi-Fi Calling on an iPhone

1. Open the Settings app on your iPhone and select ‘Mobile Service’.
2. Locate the ‘Wi-Fi Calling’ option and enable ‘Wi-Fi Calling on this iPhone’.
3. If you have a dual-SIM model, choose the desired line under ‘Mobile’ before enabling Wi-Fi Calling. Note that this feature may not be available if your current plan does not support it.
