SIM card helps you connect with the network service provider to make, receive calls and texts. While this is the case, the internet also functions through the SIM card. There are many instances that your SIM card may fail to connect with the network service provider. What if there is no signal? What If the SIM card is dysfunctional? You can still connect to the internet if you have a smartphone.
Functions of a SIM Card
SIM card is a microchip that your GSM phone has. It is the one that processes calls and texts through the parent network. For example, if you are calling someone from the phone, the SIM card connects the call with the network tower that is closer to your location. Once that is done, the network tower connects the call with the tower of the person whom you are calling. The receiving network tower connects with the person’s phone, and you start talking without any interruption. All this operation happens in a second, while it depends on the person whether he picks the phone or not to talk.
Further, the SIM card helps in connecting to the internet as well. The data connection is also possible through the SIM card as it delivers data packets and receives data packets through the tower. High-speed internet is also possible these days.
One important aspect, you must also understand here is, though the SIM card is a significant part of your communication channel through your cellphone, you can still connect to the internet without that too.
How to Connect to the Internet Without a SIM Card?
The smartphone offers you the flexibility to connect with the internet even without a SIM card. You must realize that smartphones are smart enough and they can function even without the microchip. There are two modes to connect with the internet without a SIM card. Though the technology is the same, the mechanism is different.
- Mobile Hotspot Connection
- Wi-Fi Connection
If there is someone who has an appropriate signal in the phone with a proper SIM, you can connect to their internet. All they have to do is, open the hotspot of their phone and offer you the password to connect if they have set one. However, the speed of the internet might differ in this case. As the person who is sharing the hotspot might also use the internet. The bandwidth might be reduced causing slow speed.
The next way is, if there is a Wi-Fi source for the internet, you can connect the same with your phone. As you establish the connection, you can access the websites and use the Apps available on the phone as well. It is also to be understood that, even if you have a SIM card and a Wi-fi Source connected, the speed of the internet can be enhanced. You can attempt this and see the difference.
So, your phone does not require a SIM card to connect with the internet but a source to establish the connection.
