Technically, our unlimited data plans are limited to data use only. For example, you can't insert the SIM card into a phone and have it operate as a regular cell phone plan that supports calls, text messages, and data.However, depending on the devices and apps you use, it may be possible to send and receive texts and phone calls. Contact us for more details.Also, hotspots cannot send text messages, but they can typically receive them. However, they're usually limited to system generated messages regarding activation status and data usage.
