Can You Use Call and Text SIM in Mifi Device?

Are you considering using a mifi device for internet connectivity, but wondering if you can also use it for making calls and sending text messages? In this blog post, we will explore the possibilities of using a call and text SIM in a mifi device.

Understanding Mifi Devices

Mifi devices, also known as mobile hotspots, provide a portable way to connect to the internet using cellular data. They work by creating a local Wi-Fi network that multiple devices can connect to, allowing users to access the internet on their laptops, tablets, or smartphones.

Using a Call and Text SIM

Typically, mifi devices are designed to work with data-only SIM cards, which means they do not support voice calls and text messaging. These devices prioritize providing internet connectivity over voice services. Therefore, if you insert a call and text SIM into a mifi device, you may encounter some limitations.

Firstly, mifi devices usually lack the necessary hardware, such as microphones and speakers, to facilitate voice calls. Even if you manage to insert a call-enabled SIM card, you won't be able to make or receive calls directly from the mifi device.

Secondly, texting is not supported by default on mifi devices. While some mifi devices may have a basic text messaging feature in their interface, it is often limited in functionality and not comparable to a dedicated messaging app on a smartphone.

Workarounds and Alternatives

Although mifi devices are primarily meant for internet connectivity, there are some workarounds and alternatives if you still wish to use a call and text SIM.

One option is to use Voice over IP (VoIP) services. Many mifi devices support connecting to the internet using Wi-Fi. By using a suitable VoIP app, you can make calls and send texts over the internet instead of relying on traditional cellular networks. This method allows you to utilize your call and text SIM indirectly through the mifi device.

Another alternative is to use your call and text SIM card with a compatible smartphone or feature phone and then establish a personal hotspot using your phone's internet connection. This way, the mifi device can simply connect to your phone's hotspot, providing internet access while still utilizing the call and text functionality of your SIM card.

Considerations and Limitations

While the workarounds mentioned above can enable call and text functionality with a mifi device, there are some important considerations and limitations.

Firstly, utilizing VoIP services requires a stable internet connection with sufficient bandwidth. If the mifi device's internet speed is not adequate, call quality may suffer, and text messages might be delayed or unreliable.

Additionally, creating a hotspot with your smartphone and connecting the mifi device to it can consume more battery power. Both devices will be actively using their radios and processors, which may result in reduced battery life.


In conclusion, while mifi devices are primarily designed for internet connectivity, there are options available to utilize call and text SIM cards. However, these workarounds come with limitations, such as potential call quality and reliability issues, as well as increased battery consumption. It's essential to consider your specific needs and the trade-offs involved before deciding whether to use a call and text SIM in a mifi device.
