The Different Ways You Can Make Calls Without a SIM Card Explained

What are the top ways for making calls without using a SIM card? Find out all your options!

SIM cards are a key part of your cell phone, and most people find that they can’t make calls without one. Your SIM contains your personal number and a lot of your other cell phone-related information. It tells you who the carrier is, the country code of origin, and a user ID that is unique to you. Without a SIM card, you may find that making calls isn’t possible.

However, you may not always want to use a SIM card to make a call – you may have lost your card, you might have damaged it, or you may not want to use your number for the call. You might also have no signal on your cell phone.

In this article, we’re going to find out, if can you call without a SIM card, and if so, how? Some of the top options include things like WiFi calling, using VoIP, and using a messaging app – so let’s find out more about these.

WiFi Calling

Make Calls Without a SIM Card

What Is Wi-Fi Calling?

WiFi calling is probably one of your best options if you are looking for a way to make a call without a SIM card, although it does require a bit of setup. It can only be used if you have access to a Wi-Fi network.

Wi-Fi calling uses a built-in feature on most smartphones (although not all) and it will allow you to make the call using the Wi-Fi network instead of using your cell carrier’s coverage. You may have to pay an access fee for this in some cases, so it’s important to check in advance. For some people, this is included in their cell phone package.

You will need to contact your provider if you want specific instructions on how to set up the Wi-Fi calling feature on your phone, but in most cases, the process will involve the following steps:

  1. Check that you are connected to a viable Wi-Fi connection
  2. Activate the HD Voice function (you may be able to find this under Advanced Voice Settings for older smartphones; most modern smartphones have it automatically activated)
  3. Accept the Terms; Conditions for Wi-Fi calling when this box appears on your phone
  4. Check and confirm that the US address entered is correct, or update it if it is not correct

You may also need to check whether you have the setting “Wi-Fi calling” enabled on your phone. You should also make sure that your data is turned off, as you won’t be using this for the call.

If you are not able to access Wi-Fi calling using these steps, try researching a guide for your specific model, or contact your cell carrier for further information.

What Are The Benefits Of Wi-Fi Calling?

Wi-Fi calling is a great option if you are going to be somewhere with limited or no reception because it lets you take a Wi-Fi network’s signal instead of looking for your phone carrier’s signal. This allows you more flexibility about where you call from.

It’s great as a backup option for companies when servers go down, too, and it may help you save your data. In some cases, it will be cheaper or possibly even free, making international phone calls a better option (if they are available).

There are lots of instances in which both individuals and workplaces can benefit from it.

What Are The Drawbacks Of Wi-Fi Calling?

One of the biggest drawbacks is that you do need a reliable Wi-Fi network and you may not have sufficient speed, especially if you are trying to do this in a public place where lots of other people are also using the network.

Furthermore, in most cases, you can’t use this feature when abroad; most cell phone suppliers restrict it to US phone calls only. Some will also prevent you from calling internationally, although this depends on your carrier.

You also can’t move away from the Wi-Fi network. Some cell phones do automatically switch to using your cellular connection if you get out of range of the Wi-Fi, but not all do. If you want to learn more about this, get in touch with your provider.

Which Devices And Carriers Allow Wi-Fi Calling?

Most modern devices allow Wi-Fi calling, and all major US carriers do. That includes Verizon, Sprint, AT&T, and T-Mobile. If you have an old smartphone, you may not enjoy this feature but check with your company before you dismiss it as an option.

How To Make Calls

Landline and desktop calls tend to be as simple as dialing the recipient’s number into the phone and waiting for them to pick up. This is very straightforward.

The biggest advantage of landline and desktop phones is that you don’t need either an internet connection or cellular service to make calls. They tend to be stable connections, and a lot of people still have them.

How Does This Compare With Other Options?

Landline phones tend to be considered old-fashioned when compared with the other options, mostly because they have to be used in one place, and they require dedicated equipment. Since most people today have access to cell phones and reliable Wi-Fi networks, the other options are often preferable, even without access to a SIM card.


You can still make calls even without a SIM card, using a Wi-Fi connection, VoIP options, messaging apps, or a landline phone. It’s important to think about how much portability matters to you, as well as what sort of connection you are likely to have. 

If your connection won’t stable and you don’t need to move around, a landline may be the best option, but otherwise, consider one of the other solutions. It’s likely that in the future, more and more people will move toward these as alternatives to traditional phone calls or using cellular service.
