LAST UPDATED: April 16th, 2023

In today’s digital society, parents may find themselves in a stage where they need the convenience of instant communication with their child, but are hesitant to give their child a phone because of risks associated with smartphone usage such as exposure to adult content, bullying, screen addiction, and online predators. 

The Cosmo Smartwatch, as a child’s first device, is a bridge into the digital world for children and parents. With the smartwatch, parents and children benefit from the convenience of instant and secure communication while simultaneously offering children a sense of independence. The Cosmo Smartwatch includes the following features:

  • 4G connectivity on U.S. networks
  • Real-time GPS tracking
  • SOS alert mode
  • Geofencing
  • Secure phonebook
  • Locked-down internet
  • Wi-Fi enabled
  • Waterproof

The Good

  • Instant Communication Without Internet Access
  • GPS Tracking and Geofencing
  • Secure Phonebook
  • Durable and Waterproof
  • Free with 12-Month Subscription Plan
  • 30-Day Return Policy

Instant Communication Without Internet Access

Although there are apps and smartphones with parental control features, smartphones may still pose a risk to children through its core features such as internet browsing, social media, unrestricted messaging, and app stores. In contrast, the Cosmo Smartwatch does not have internet access or apps, easing monitoring concerns for parents. The smartwatch enables instant communication through voice calls, text messages, voice messages, and video calling on 4G LTE networks in the United States. The smartwatch also has an SOS alert mode where a child can ping their parents’ phone with an urgent alert and call emergency contacts.

GPS Tracking and Geofencing

The Cosmo Smartwatch provides real-time GPS tracking so parents can know their child’s location at all times. In addition to the GPS tracking, the smartwatch also offers geofencing where parents can set up safe zones and receive an alert if their child leaves the zone. Location accuracy depends on which method is being used to report the child’s location. When outside in an open area, the accuracy is between five to ten meters. When indoors connected to Wi-Fi, the accuracy is between 50 to 100 meters. Location Based Tracking (LBS) triangulates the watches position by using cell towers; the accuracy of LBS is between 500 to 2,000 meters. LBS is only used when both GPS and Wi-Fi are unavailable. 

Secure Phonebook

Through Cosmo Smartwatch’s secure phonebook, children are only able to call saved contacts. The phonebook can store up to 30 contacts enabling safe communication between the child and multiple family members and friends. Additionally, there is a block stranger calls feature in which calls from unknown numbers are blocked. 

Durable and Waterproof

Designed for children in kindergarten through eighth grade, the Cosmo Smartwatch is durable and waterproof. It has no glass features and is comfortable to wear. The watch is rated IP67: it is protected from dust and is waterproof in up to three feet of water for up to 30 minutes. The watch can withstand daily functions such as washing hands or rainy days, but it is recommended to remove before swimming or showering.

Free with 12-Month Subscription Plan

The Cosmo Smartwatch is free with free annual upgrades when parents sign up for a 12-month subscription. When parents opt for a 12-month subscription, they also receive a 30 percent discount on subscription services. Cosmo Smartwartch’s subscription includes unlimited 4G data, calls, and messaging. If parents do not want to commit to a year, they can sign up for the month-to-month subscription service and buy the device for 75 percent off. 

30-Day Return Policy

If parents are unsatisfied with the Cosmo Smartwatch, they can return the smartwatch for a refund of the initial activation fee, return shipping costs deducted, within 30 days of receipt.


The Bad

  • Short Time in Business
  • 6-Month Limited Warranty

Short Time in Business

There is no clear indication as to how reliable the smartwatches or services are as Cosmo Smartwatch has only been in the industry since June 2020.

6-Month Limited Warranty

Although a six-month warranty is included with the Cosmo Smartwatch, its competitor, the LG GizmoGadget, has a 12-month warranty.


The Bottom Line

The Cosmo Smartwatch provides parents and children a first device that is a simple and secure method of communication without the litany of risks associated with smartphone usage at an early age. The smartwatch has all key features desired in a smartwatch phone for children: calling, video calling, messaging, GPS enabled, geofencing, secure phonebook, durable, and SOS alerts. The overall cost of the watch and subscription services is similar to the LG GizmoGadget, but has the added benefit of unlimited 4G data, calls, and messaging that isn’t provided for the GizmoGadget when enrolled through Verizon Wireless.

Cosmo Smartwatch is new to the industry, and although it provides a six-month warranty, it is not clear how reliable the smartwatch or services are as it's only been in business since 2020. Parents are able to return the smartwatch within 30 days of receipt if they are unsatisfied with the services.

Complete waste of money and trust. We bought two watches for our children in school so we can keep in contact with them when needed. And it turns out to be totally worthless. The watch shows the signal strength is normal. When my son calls me, my phone rings. But neither of us can hear each other. Texting doesn’t go through either way. Imagine at the moment you need to get in touch with your children, and that’s exactly when COSMO fails. Too bad for us we bought an annual plan! We are stuck for a year! Don’t make the same mistakes!

This product was incredibly difficult and confusing to set up. Also, the technology didn't work as it was supposed to. I couldn't reach anyone from customer service to help me, either on the app or over the phone. When you call the customer service number, you just get hung up on over and over again. I have now received numerous automated emails from the company telling them how much they care about me, but haven't been able to speak to anyone. At this point, I am trying to cancel the product and subscription and get a refund, but I can't get through to anyone to do that. This whole experience has been an absolute nightmare. Definitely recommend going with a different product as this one is a complete waste of your time and money!

It does what it says in their website. With this Geolocation feature I KNOW where is my son, which gives me peace of mind. I can call my son and he can call me anytime from anywhere. It's a big deal when he is 4 years old. And if he just need some encouragement, he send me a short voice text, and I reply "Good Job!". It makes a huge difference in his confidence. This Cosmo Smartwatch definitely contributed to build our father-son relationship.

Georgia Richmond Mayagüez,

In a day and age where social media is absolutely recking our children’s self-esteem, it’s so hard to decide when they should have a phone. We want them to be safe, to know where they are going, we want them to call if anything goes wrong, while also protecting their social intake. Cosmo watch is an amazing tool for parents in that in-between stage with their children. Letting kids be kids just a tad longer!

This watch is terrible. I purchased three of them and still cannot get any of them set up. It's been two weeks and I'm trying to get my money back for the plans and insurance I bought. I've tried contacting customer service and they're awful as well. Supposedly I'm getting a call back but I'm not holding my breath. I've spent almost $1000 between the watches, plans and insurance and they are awful

Greatly appreciated the simplicity and focus on security features without all the unnecessary distractions from a phone. I was looking for a device which provides a sense of safety and the ability to communicate, without the entire world having access to the child. That's exactly what COSMO is - really thankful something like this exists!

This product has changed our lives!! We are so fortunate to have found Cosmo. The technology is everything we need. Being able to connect and track our child has given us so much peace of mind. I’ve been recommending to our family and friends!

The charge does not last and the signal is not consistent. We purchased this for Christmas and tried to return it before it had been activated 30 days, but the guarantee only applies to 30 days from the purchase date. Look elsewhere for a watch option!!

Great product for parents looking to communicate with and keep track of kids! Easy to set up and customer service was great when we had a few questions. Definitely recommend as a cell phone alternative

This watch is VERY cheaply made. It is difficult to navigate through the options - and at the same time, it is extremely easy to make an incorrect selection (like, accidentally changing the language to Korean when trying to change something else in the settings). Additionally, the watch has never worked correctly. It would never make nor receive calls - and the texting feature is very limited. It did not accurately track my child's location either - often showing him several states away, when I knew for a fact that he was just at our neighborhood park. Overall, pretty unhappy with the purchase and will just send my child out with a walkie-talkie as that is a better option than this watch.

Same as others have noted. Purchased, setup a subscription, watch won't connect. Customer support is non existent. Clueless and stammering... Looks like a waste of money right now

Don't waste your money. The service is spotty at best and we live in an area where we have never had a problem with other providers. Tech support is untrained and cannot resolve issues. They pay customers to leave 5 star reviews by giving then a free month of service.
