Gabb Wireless is a cellular service company that provides devices with limited access, meant to serve as a child or teen's first device.  They advertise that their devices cause families "Less Tech Stress.  No internet. No social media.  No worries."

Please be aware that there are usually discounts on device purchases (which are sold separately from the monthly cellular service).  When the devices are sold out online, our reviewer found that they are very reasonably priced--and often cheaper--on Amazon.
