How to Make a Phone Call Without a SIM Card?

When mobile phones first hit the market, they were tied to a specific carrier and had physical SIM cards. Today there are plenty of ways you can make a phone call without a SIM card— from Voice over Internet (VOIP) Protocol services to app-based solutions that use Wi-Fi networks instead of traditional cell towers.

Here is an overview of how you can do this in the most convenient way possible!

1. Wi-Fi Calling

WiFi Calling is a type of Voice over Internet Protocol (VoIP) technology that allows users to make phone calls, or video calls, using an internet connection.

Wi-Fi Calling

You don’t need a SIM card for the service, nor do you have to be connected to any cellular network, which is ideal if there’s poor phone coverage in your area or expensive plans available.

How to Call Without Sim Card Using WiFi?

Here are the steps on how to call with WiFi without SIM:

Step 1: Check Your Device Compatibility

Make sure that your device supports WiFi calling by checking with your carrier or looking up its specifications online. Not all devices support this feature, so it’s important to double check before proceeding. 

Step 2: Connect to a WiFi Network

Once you have confirmed that your device supports WiFi calling, connect it to an available WiFi network (such as one at home or work). This will allow you to make calls over the internet instead of through traditional cell towers. 

Step 3: Enable WiFi Calling on Your Device

After connecting to a compatible WiFi network, open up the settings menu on your device and look for “WiFi Calling” or “Voice & Data Over Wi-Fi” under Network Settings or Call Settings, depending on what type of phone you have (e.g., iPhone or Android). Toggle this setting on if it isn’t already enabled so that you can start making calls over the internet instead of through traditional cell towers when connected to wifi networks. 

Step 4: Place Calls Over Wi-Fi

Now that everything is set up correctly, simply place a call like normal from either the contacts list or dialer app – just remember that both parties must be connected via Wi-Fi for it to work properly! You should see something indicating that you are making a call over Wi-Fi next time you initiate one; otherwise, there won’t be any difference between placing regular voice calls and ones made via Wi-Fi other than potentially better sound quality due to higher bandwidth speeds associated with these types of connections.

2. WhatsApp Calling

With WhatsApp, you can make voice and video calls conveniently with the app without having to use a SIM card or your cell phone plan.

WhatsApp Calling

All that is needed is a valid phone number and access to WiFi! With WhatsApp Calling, users have the ability to place calls through this app using only their WiFi connection—no need for additional plans or SIM cards.

Step 3: Add Contacts

Once you have registered, add contacts that you want to call from within the app itself or import them from your address book if they already have WhatsApp installed on their devices as well. 

Step 4: Select the ‘Call’ Option

Tap on any contact’s name that you want to call, then select the ‘Call’ option at the top right corner of the screen next to their profile picture/name or status message (if available). 

Step 5: Check Internet Connection

Make sure that both users have a good internet connection before starting a call so as not to experience any issues while talking over voice chat via WiFi or cellular data connection (depending upon what type of network connection is available). 

Step 6: Make Calls With Ease

The call will be connected instantly once both parties accept it, allowing them to communicate over audio in real-time.

3. VoIP Calling

VoIP, short for Voice over Internet Protocol, is a communication method that leverages an internet connection rather than a phone line.

VoIP Calling

It’s often referred to as services like Skype, allowing users to make video calls online without needing to use SIM cards or have any phone plan.

Step 2: Set up Your Account

Once you have chosen a provider, sign up for an account by providing basic information like name, address, phone number etc., along with payment details if required. 

Step 3: Download and Install the App

After signing up for an account, download and install the mobile app provided by your VoIP service provider on your device or computer. 

Step 4: Configure Settings

Log in to the app using your credentials and configure its settings such as voice mail, ringtone etc. so that you can use it as per your requirements. 

Step 5: Make Calls 

Now you can start making calls either through Wi-Fi or 3G/4G network connection depending upon the availability of data plans in your area at low cost or even free of charge in some cases!

4. Google Voice Calling

Google Voice is an impressive app for making and receiving calls without using your mobile phone’s SIM card.

Google Voice Calling

How to Call Without Sim Card using Google Voice?

Here are the steps on how to call with Google Voice without SIM:

Step 1: Create a Google Account

You will need to create a Google account in order to use Google Voice. This can be done easily by visiting the official website and following the instructions there. 

Step 2: Download the App

Once you have created your account, download the Google Voice app from either Apple or Android stores, depending on which device you are using (smartphone or tablet). 

Step 3: Sign In

Once downloaded, open up the app and sign into your account with your username and password credentials provided when creating an account earlier on. 

Step 4: Set up Your Phone Number

The next step is setting up your own personal phone number that people can use to contact you via Google Voice instead of having them call directly through their SIM cards in their phones. You will be asked if you want to port over an existing number or choose one of those available in different area codes across America (or wherever else you live). 

Step 5: Make Calls With Ease

After completing these steps, all that’s left is making calls! Just enter someone’s name or number into the search bar within the app and hit “Call” – this will then dial out through your new virtual phone number line rather than needing their physical SIM card present in order for them to receive it like before!
