in general, You can use a phone without a mobile SIM. Smartphones without a SIM cannot make normal calls or send text messages on the cellular network. Secure messaging apps can replace this functionality by making use of WiFi. Phones can call emergency services without a subscription or package from the telecommunications company.
With wireless internet coverage in most homes, businesses, and communities, You can test that your SIM is not being used by removing it and restoring it securely. We will also discuss some frequently asked questions regarding phones without SIM cards. Stick to the end to discover some ingenious ways to use an old smartphone!
Can you still use WiFi without a SIM card?
You can connect to WiFi even if your phone does not have a SIM card. The SIM has a different function; It does not interfere with your phone’s ability to connect and work on WiFi.
Your SIM card will authenticate with its cellular service provider by identifying it with IMSI (International Mobile Subscriber Identity). After selecting the SIM card, The mobile network will locate and store your phone in the central database of the mobile network. The database contains permanent subscriber information known as HLR
This is how your SIM card works when you connect to your Android device or iPhone service provider.
How does WiFi work?
WiFi works differently. Your phone will search for wireless networks running on wireless routers in the area. These wireless networks are not connected to cellular networks. However , They are still connected to the Internet via an Internet Service Provider (ISP). Using WiFi (IEEE 802.11), Your phone will connect to the router through a certain wireless frequency, giving him access to the internet.
WiFi coverage is limited due to the small size and power of most routers. This means that you have to be within range of a router to get a strong signal. There is no guarantee that WiFi routers will emit signals that can penetrate thick concrete walls over long distances.
and then , If you are planning to use your iPhone or Android device with WiFi, Ensure that your home has full coverage by placing additional WiFi extenders or access points. Your best bet for optimal coverage would be to create a mesh network in your home.
Unfortunately , Mobile data does not solve the problem of no SIM card or strong WiFi signal. Mobile data works via your mobile service provider, And not WiFi.
How can you surf the internet without a Sim or WiFi?
If wireless and SIM are not an option for you, There are still ways you can get online:
The first method is to share data via Bluetooth by linking two phones together. This option is only available on devices running Android version 2.2 and above. All you have to do is pair the two devices together, Then enable “bluetooth tethering” on the device that can access the internet. very simple , is not it?
Using Mobile Hotspot
Another solution is to connect your iPhone or Android smartphone to such a portable hotspot via USB cable or WiFi. The mobile hotspot works by making an LTE (mobile data connection) connection and converting it into a WiFi signal, Thus it acts as a router. You can think of it as a portable wireless router.
If WiFi is not working properly on your phone, Try looking for a wireless router in addition to a USB-C to Ethernet cable or USB-C to Ethernet cable adapter. Using the adapter and network cable, You can connect them directly to one of the ports on the router. For your information , Only devices with USB-C will be able to work in this way. Older USB versions are not advanced enough to send this type of data via cable.
Use a WiFi hotspot
The last way you can access the internet through your cell phone is by linking to another device with its WiFi hotspot enabled. This is similar to tethering via bluetooth, But the device with the hotspot enabled will appear in your network connections. You will need a password to connect to it. This is arguably better than Bluetooth, Because WiFi is much faster than Bluetooth.
What happens when you call without a SIM card?
Since your mobile service provider cannot register your SIM card on their network, You will not be able to access their coverage. This means that you will not be able to make any calls. If you try to connect, The recipient’s mobile phone will not ring. You’ll go straight to voicemail or you’ll be immediately disconnected.
Keep in mind that SIM cards run on GSM technology now. In this way , You can use the service of other cellular service providers to make emergency calls if you do not have sufficient network coverage of your own.
If you do not have a SIM but have access to the Internet using mobile data, You can make data calls. You can do this using many communication apps like Skype, WhatsApp and the best option is Signal. You can connect to other phones and make WiFi calls – as long as that phone is also connected to the internet.
Do you want to receive text messages without a SIM card?
This function works similarly to trying to make calls to another phone without using a SIM card. If your phone does not have a SIM card, Your mobile service provider will not give you space on their network. And therefore , You will not be able to receive or send any SMS or MMS messages.
However , Suppose you are connected to the internet via WiFi, tethering, or hotspot. In this case , You will be able to use applications that allow you to send messages. WhatsApp is the most popular messaging app in the world, But there are many other apps with messaging capabilities.
Some examples include: Signal – Facebook Messenger – Google Hangouts – Snapchat – Instagram – Twitter – Skype
This is not the complete list. But you can take a look at the best messaging apps that I have reviewed that allow you to send text messages using WiFi.
Can you use mobile data without a SIM card?
Mobile data requires a SIM no matter how you want to slice it. This is because this type of data is sent over the mobile service network – not WiFi. And therefore , If you do not have a SIM card, You will not use mobile data.
Many mobile network providers offer SIM cards that are loaded with data. This type of data plan comes with options to pay for a top-up or a recurring subscription. These SIM cards will not allow you to make calls or send text messages (SMS or MMS). However , This will enable you to connect to the internet using mobile data without the need for a WiFi connection, tether or hotspot.
It’s usually cheaper to just load the data SIM in the SIM tray in terms of the monthly plan. If you don’t make a lot of calls and are looking for a budget plan, Then this option is perfect for you!
What can you do with a phone without a SIM card?
without a sim card, You may think that your phone is just a heavy weight. But this is not the case. Actually , There are many reasons why keeping and using your old smartphone can be very beneficial.
If you are an active crypto trader, Using an old phone that’s been switched to airplane mode will be safer digitally for you. The best way to store cryptocurrencies is in an offline “cold wallet”.

By reusing your old smartphone, and install a trusted wallet app, and remove the SIM card, You will get the best form of digital encryption – without an internet connection! Of course , You can connect your phone to the Internet via WiFi when needed and put it back into airplane mode when everything is done.

Safe Haven is an app that turns your phone into a personal protection device that allows you to hit the panic button if you feel threatened. no need to be confused, But there is an open source project with a similar name called Haven from the Guardian Project. This application uses a large number of sensors available on your old smartphone to monitor the room. If the application is running, It will notify your main device.
