I bought one for my child with special needs. I got the one with the SIM card included. Set up the watch and subscription. The text worked initially but calls and gps didn’t. GPS said the location wouldn’t work within 72 hours. 4 days later I reached out to them through Amazon and received a reply saying they would reset the watch I replied asking a few questions and they answered my queries and told me to let them know when they could reset it, I replied telling them they could do it when they were ready. Nothing happened so I decided to send it back and replace it. The same thing happened but this time no calls, texts or gps. I reached out again explained I returned the original and was told I hadn’t replied to the original agent telling them when to reset the watch. So I said I had replied but as the problem persisted I decided to get another one. I received no response. After trying 2 watches and the same problem happening with both I decided to send the second one back too. I messaged them to tell them I wanted to cancel my subscription as I had sent 2 watches back and had a reply asking me to let them try and fix the problem before I did this. I told them I had given them 2 opportunities to fix the problems before I decided to return them and please just cancel my subscription, I received no reply.The idea is a good one and it does seem that, for some people at least, they do work, however I would suggest you purchase the watch from Amazon as it is easier to return if faulty but make sure you get one without the subscription.UpdateAfter posting my review, Paula from Xplora reached out to me about the problems I had with both watches and asked me if I would like Try a free upgrade.I’ve had the new watch for a few weeks now and I can honestly say it works really well. The school mode is great and means that he can still wear it during school time. The GPS has worked really well except for one instance when my child seemed to teleport from school in Manchester to Legoland in Windsor, however, the incorrect location reporting is really good and easy to use. I would recommend the XGO3 as it is exactly I was looking for initially.
